Family Murdered in Guryeong

Is the Eldest Son, the Elementary School Boy, the Main Suspect?

Was this your doing?

No.

You didn't see anything that day?

Right, I didn't.

I didn't see a thing.

Guryeong Police Station

The Almighty...

never answered my prayer.

I ended up a killer.

My first kill was sloppy,

and I remember being exhausted.

However, the excitement and thrill I felt that day...

lingered in my thoughts.

This morning, at a boxing club in Seokjin-dong, Moojin,

the severely burned body of the head trainer was found.

The victim turned out to be...

a bereaved family member of a victim of Head Hunter,

the serial killer who terrorized the country 25 years ago.

After that day,

the killings continued.

Mutated DNA surfaced as society evolved,

creating psychopaths.

The top 1% of those are known as predators.

Just like it's a lion's instinct to hunt for rabbits,

to these predators, other human beings...

are nothing but prey.

I'm a predator.

That's how I was born.

Mouse

You jerk, stop right there.

Episode 2

Stop right there!

Let go!

Darn it.

Darn.

Take that.

You have the right to remain silent and to an attorney.

Anything you say can be used against you in a court of law.

Hold on. Are you going to shoot me?

You're insane. A cop can't do this!

You're right. I've lost my mind.

Help. Is anybody there?

- Help! - Shut it, will you?

You want people to help a murderer?

Just stay still. I'll be quick.

Moo-chi, please. Don't do this.

Don't let that man ruin your life.

What the...?

Where are you off to?

Get over here.

Where are you going?

Hey! Get down from there.

If you fall and die, this chase would've been for nothing.

Fine. Shoot, then.

Shoot and I'll jump!

Who said I'd shoot?

I was only messing with you to scare you.

Messing with me? You're the one from before.

You shot me in the back after telling me to run away!

Darn him and his good memory.

Okay, fine. I'll arrest you instead.

Come down from there and I'll arrest you.

Come on. Get down here.

Get back here.

Think wisely.

You raped those sisters,

and beat them to death with a hammer,

but this darn country won't ever execute you.

Instead, you'll be stuck in a prison cell forever.

Someone with a pretty face like you?

You should know that prison houses all sorts of perverts.

I won't be able to help then even if you beg me to kill you.

Hey! Unbelievable.

Were you really going to jump?

Are you deaf? Didn't you just hear what I said?

I didn't camp outside your girlfriend's home...

for a year just to see you jump off a building.

Get down here!

If you jump from here, your intestines will fall out.

They'll burst on the street.

Think about those who must clean that up,

you selfish jerk,

so let's take the cleaner route.

Okay, fine. Just stay there,

and I'll shoot from here.

You can land on the ground with my bullet in you. Okay?

Okay.

Gosh.

I should really quit drinking.

Where did you go?

Did you really jump?

Darn it.

He just couldn't be of any help, could he?

Hello?

I was on my way to church at dawn, and I saw a big flash,

so I came to check what it was.

I can't believe this.

She struggled to raise a daughter all by herself.

Do I smell alcohol?

My gosh.

What?

You keep moving.

Don't move, okay?

Stay still.

Moo-chi.

Hey. Did you see that?

The corpse keeps moving.

This is so cool.

Didn't I warn you not to get drunk and mess with my case?

You're upsetting me. You talk like we're strangers.

This isn't your case. It's mine.

- My gosh. - This was done by that jerk.

Look. It's pretty obvious.

- You called him, didn't you? - He kept calling me.

- He killed her. - I'll take care of him.

Listen. Hey, let go.

- Come on. - Let go of me, you punk.

- Let's go. My gosh. - I swear he killed her!

- How drunk are you? - This is my case!

Gosh. Wait.

Gosh, no way.

This is new. I didn't even remove the tag.

This way.

- Make sure he stays here. - Okay.

I swear I'm right!

It's that jerk!

- He killed her! - I'm sorry.

He forced me to call him whenever there was a murder case.

He's doing an interview.

Stop him. Stop him from saying anything!

This was committed by the guy who recently killed the gym trainer.

I'm certain it was him.

He killed her too.

Maybe he's one of those guys who hates God,

or maybe he just craves attention.

The police are investigating the case with the assumption...

that the trainer and female employee were killed by the same culprit...

who has hatred toward a certain religion.

You failed again?

I'll grow old and die at this rate.

I won't let that happen.

Has it been a year?

You swore to kill the guy who killed those sisters with a hammer...

so you could come in here to kill me too,

but you're still on the other side.

What's the rush?

You'll die anyway.

You just wait.

He was a small fry.

This time, I think I found the real deal.

Ko Moo-chi.

You'll...

eventually fail.

What?

You can't kill people.

I can tell just by looking into your eyes.

I can tell if you're someone like me, or just an average human being.

I thought you were a brain doctor, not an eye doctor.

To have the ability to kill someone,

you should have emptiness in your eyes,

but your eyes are filled with emotions.

Anger, pain,

regrets, sympathy,

and love.

Cut the nonsense.

It's not something you can work on.

You're just born with it,

so don't try too hard.

Quit talking nonsense and just wait until I cut you.

It won't take long.

Fine.

I'll look forward to it, kiddo.

Next time, you'd better stab me properly.

Not here.

Do it right here.

Recently...

I found a Bible at a murder site,

and I read something very memorable.

That really taught me something.

"Anyone who takes the life of a human being is to be put to death."

"Anyone who takes the life of someone's animal..."

"must make restitution."

"Fracture for fracture,"

"eye for eye, tooth for tooth."

Leviticus 24:17-20.

Amen.

I used to bad-mouth the great god up there,

because He'd always talk about forgiveness,

but it turns out He knows what He's talking about,

so I figured I should follow His words.

I should return exactly what was done to me.

I should do more than just teach you a lesson.

It totally spoke to me.

I should do what you did,

and kill you in front of your kid.

That's what an eye for an eye and a tooth for a tooth means.

That's what God is trying to teach us, right?

That's too bad.

I have no children.

That's too bad. I saw your child.

Don't dare lie to me.

I saw your wife and child...

with my own two eyes.

He's dead. To be more exact,

I killed him.

I heard psychopaths have...

an unbelievable amount of love for their kids.

Why?

You don't want your kid...

to see you be killed?

Then again, that kind of incident...

is extremely hard to forget.

It stays with you forever.

Han Seo-joon, you just wait.

I'll make sure...

your child feels the same kind of pain...

I felt for life.

This is quite unexpected.

I'm surprised you came to see me.

How's our kid?

You should've brought him with you. I wanted to see him.

He's dead.

- What? - To be more exact,

I killed him as soon as he was born.

I did it with my own two hands.

I came to tell you that.

He looked a lot like you.

That's why I killed him.

I didn't want him to turn into a monster like you.

How dare you...

kill my son?

How dare you?

My son...

is alive?

Next, you need to remove the thorns,

but leave a small twig.

She's so good at this.

People keep complimenting me after I started taking lessons here.

Really?

They're crape-myrtles.

Ko Moo-chi

They symbolize a longing desire to meet the person you miss.

Don't you remember me?

I went to your home before.

You did?

Snowman.

Snowman...

You...

Give me money.

What? What...?

My brother got surgery nine times thanks to your husband.

Tomorrow, he needs to get surgery again,

but they won't operate if we don't pay the balance.

They'll...

They'll just let him die.

I'm...

I'm sorry. I'm really sorry.

You're sorry? I don't need your "sorry."

Give me money!

- Student... - Give it to me now.

Give me the money.

This is wrong. Why must we live like this?

You're living just fine, so why?

Why? Why must we live like this?

Your husband, the Head Hunter,

was a successful doctor.

He must've made a lot of money.

Give me money. Give it to me!

My brother will die if he doesn't get surgery!

Wait.

Let's talk somewhere else.

Give me money.

Give me money for my brother's surgery!

Mom.

What's his problem?

I'm very sorry.

Are you trying to get yourself killed?

I'm sorry. I think...

this bird broke its leg.

It wouldn't move when the car was coming, so I instinctively...

You must've been startled. I'm sorry.

You almost died because of that bird!

You're right. I'm sorry.

I'm sorry. Have a nice day.

I'm sorry.

Is he kind or stupid?

Hey. I'm out of thread.

My hands will get stiff if I don't practice.

You know threads are banned.

Medical equipment especially can't be used freely by inmates.

Bring it.

Your predecessors gave them to me without complaint.

Do you think I studied until I got sick...

to pass the civil-service exam and become your servant?

Don't be scared.

Keep it down!

You must think you're a king because everyone's scared of you.

Get over yourself. You're nothing but a mayfly...

with limited time left.

Your threats don't work on me.

"Your threats don't work on me."

That's what I told him.

- What is this? - You're new, so you don't know.

Didn't you hear about the guard...

who became disabled and retired after upsetting Han Seo-joon?

He doesn't do anything himself. The others just do it on their own.

Look the other way, and bring it to him.

Where are you? Are you on your way?

You forgot your ID? Stay there. I'll get you.

Hello.

Repentance, Salvation, True Reform

Please bring the costumes here.

- Hey. - Did you bring it?

- Of course. - The cards too?

- Cards. - Okay.

There you go again.

Do you think you're an animal doctor?

- There's Chi-kook. - Hey!

- Hello. - Hi, Chi-kook.

Wow. You look like a completely different person.

- You look great in a uniform. - Thank you.

Hey. Throw away that knockoff watch. I'm embarrassed just seeing it.

You guys got it for me to congratulate me on becoming a guard.

This is genuine in my heart.

Seriously. I'm the idiot for trusting that moron to buy it.

What kind of a cop gets scammed on a knockoff site?

He couldn't tell it was a fake from the eagle having a you-know-what?

He can't differentiate R from an N.

What's Anmani?

How could you pay $1000 for that?

That's not a you-know-what. This is a leg.

Dong-koo, get your mind out of the gutter.

That's why your nickname is Gutter Koo.

Why would it have only one leg?

Ba-reum, this is a you-know-what, isn't it?

It's not. It's not.

- Let go. - My arm is short.

Stop it. Enough.

How is work?

Well, I'm trying my best not to look like a pushover,

but it's not easy.

Ba-reum. Did you pack the thread?

- Isn't it there? - No.

I left it at home.

We can't do the show without the needle and thread.

- Look more. - Darn it.

Will this work? It's a medical thread.

- Yes, it will. - Yes. It doesn't matter.

Thank goodness.

Have you seen the Head Hunter yet? I hear he's here.

- Yes. - Let me meet him.

I even joined his fan club.

What? I wondered what birdbrains joined that, and you're one of them?

- A birdbrain? - You think murderers are cool...

because you watch movies like "Hannibal."

It's because of losers like you that scumbags like that pop up.

Didn't you watch the news?

A woman who worked hard to raise a daughter alone...

was stabbed 20 times all over her body and died.

It's because of jerks like you...

that those scumbags think they're something.

I got it, so stop.

He was hiding like a rat and killed that helpless woman.

That cowardly jerk.

I got it! I won't ask again!

Stop being so arrogant just because you're a prison guard.

- Why, that little...! - Hey.

Dong-koo quit studying for the civil-service exam.

He's writing a scenario to pursue his real dream.

It's about a psychopath or something.

He joined the fan club to gather information.

Is that itch to become a director back?

He'll be good at it.

Chi-kook. Make up over drinks later, okay?

Sure.

Will you help me?

Lift it a little higher.

This is crazy heavy. Why are we carrying it? It has wheels.

It's because of the wheels.

If they break on the gravel,

it'll mess up the show later.

Sorry.

Let's take a break.

- It must be exercise time. - Yes.

You know,

I thought inmates on death row... How do I put it?

I thought they sat in solitary confinement,

repenting for what they did to their victims and praying,

and lived like Buddhist monks,

but...

they eat three meals a day paid for by taxes from the people,

and just bum around every day.

When I see them, I wonder at times.

They say they'll never be executed before they die,

so they don't repent for what they did,

and shamelessly live carefree lives.

Imagine how the victims' families would feel seeing that.

Imagine how angry and bitter they must feel.

But...

for a brief moment today,

I was afraid of those scumbags. I'm so ashamed of myself.

What do you mean?

Actually, that needle and thread I gave you earlier...

It's him.

The Head Hunter.

He looks just like us.

Did you think he looked like Thanos?

You're saying there's a monster inside him.

I'll teach Na Chi-kook a lesson.

Find someone for me.

Geumsin-dong bus stop, Midnight, Town bus #12

Byun Soon-young

Byun Soon-young's home

He has big feet.

Moojin Bukbu Police Station

Darn, he should be here by now.

Why have you been ignoring my calls? I texted you many times too.

Congratulations. After a year of investigating,

you finally caught the Sisters Killer.

I hear he took his own life.

Still, you'll get credit for catching him, right?

You're incredible!

I can't believe I never noticed your talent before.

Flatter me all you want. I'm still done with you.

There's more to congratulate you on.

You went viral online.

"A drunken interview by a cop?"

"Instead of catching a killer, he's been catching beer bottles."

Blaming it on cough medicine was hilarious, though...

Why, you...!

I didn't drink and drive.

I wasn't even on the clock.

Can't a cop drink when he's off duty?

That being said, the one who killed the boxing-gym trainer...

Don't you know how I get when drunk?

That was the alcohol speaking.

You know I turn into a pit bull once I smell blood.

I know it wasn't the alcohol talking.

What made you link the two cases?

I can't seem to figure it out myself.

Different neighborhood and different M.O.

Tell me the link you found.

What is it? Come on. You can tell me.

Get lost.

Detective Ko, wait!

Why did you even go there drunk as a skunk?

- You should've just slept it off. - There's blood on this rice.

- Have it analyzed. - Why did you even go there?

Are you listening to me?

The same culprit?

Why don't you quit the squad and go into writing novels?

Take a chance at a best-selling author.

The familiar lullaby is lulling me to sleep.

I need to take a quick nap.

What a troublemaker.

I don't know why I even bother with you anymore.

Stress will only escalate my hair loss.

Why does he even care about his looks?

Ko Moo-chi

Seokjin-dong Boxing Gym, Song Soo-ho Case

Name: Song Soo-ho

Blood being analyzed by the NFS

Ko Moo-chi

- Excuse me. - Yes?

I'm the driver of the town bus #12 in Geumsin-dong.

- Answer me truthfully. - Unbelievable.

You were spotted there by a witness.

Yes, that's him.

He was at the bus stop when she got off.

Right.

- I remember since it was odd. - I was waiting for her...

- to ask her out, - I'm sure of it.

...so I followed her.

She screamed and ran off, so...

I mean, I'm a man of pride too.

Anyway, I just went home and that's the truth.

Get him out of here and issue a warrant for his arrest.

But I didn't kill her.

It wasn't me!

Come with me.

No, let me go. It wasn't me!

Uncuff me!

I'm telling you the truth. I didn't kill her.

You. I saw you on the news.

Detective, it really wasn't me.

You said she was killed...

by the guy who killed the boxing gym trainer.

Unbelievable. Just come with me quietly!

It isn't him. His feet are too small.

We have a witness.

The bus driver?

The bus driver saw him at the bus stop,

not during the killing.

He has five priors for assault and rape,

but not for murder.

He must've killed her while trying to rape her.

There isn't any evidence to back that up.

Moo-chi.

- What? - Don't cross the line.

Stick to your own cases.

You can hardly find your own suspects.

But he's not the culprit. Why won't he listen to me?

Then who is it?

You're still here?

Don't you have a job to do?

I'm actually quite busy.

Then please get back to work, Producer Choi Hong-joo.

That's exactly what I'm doing and you aren't being cooperative.

The boxing gym case is about to be aired,

but there's no suspect,

and the detective in charge is refusing to talk to me.

I'll have nothing to air at this point.

Then go in another direction.

I never told you to air my case on TV.

Just like the Sisters Killer case, you might bad-mouth me...

as an incompetent cop.

I'd rather not have my life ruined.

Go in another direction? That'd be highly humiliating.

I'm the award-winning producer Choi Hong-joo.

I can't back out without taking a stab at it.

Take all the stabs you want.

I guess I have no choice.

It's better to go in another direction...

than fail to air anything.

Exactly. You made the right choice.

There are other cases to talk about.

I'll make sure to tune in, okay? Good luck.

How about this, then?

What?

A cop hooked on illegal gambling.

Hey!

That hurts.

A junior of mine is writing an undercover piece...

on illegal gambling.

I stumbled onto that while helping with the editing.

You should be glad my junior didn't recognize you.

If this is aired, you'd be...

Darn it.

Should I air a show about a cop who's hooked on illegal gambling,

or stick to my original piece about the Boxing Gym case?

You decide and let me know.

Ms. Choi!

You scare me, you know. You're like a leech.

Out of all the cases out there, why are you hooked on this one?

He's Song Soo-jung's younger brother.

Unbelievable, right?

Both siblings dying like that.

I want the killer to be caught for the sake of their mother.

Is that it?

Is pity your only motivation?

This isn't just out of pity,

but responsibility.

Responsibility?

Last night, between midnight and 1 a.m.,

Byun Soon-young was murdered.

Here?

The news mentioned a drain.

She went home with food uneaten by a customer...

to give to her daughter.

I found the plastic bag right here.

This is where she was killed.

I found a footprint too.

A footprint?

- Is that...? - Don't step on it.

Is that a clue?

He's no average culprit.

The soles of his shoes had been removed,

so we can't find any evidence from them.

How did the body end up in the drain?

Did she run in that direction after being attacked?

Check these.

See the scratch marks?

She was killed here,

and then dragged about 300 feet...

to the drain.

Why?

Beats me.

Why did he go to all this trouble?

♫ I love you ♫

♫ I love you ♫

♫ I know I'm not good enough for you ♫

♫ We all get tired as we live life ♫

♫ but I'll be a shoulder you can lean on ♫

♫ Thank you ♫

Where is Chi-kook?

He couldn't come because he had to help with the paperwork.

♫ Let's sing this love song together ♫

♫ Let's sing it together ♫ Ba-reum, it's your turn.

Are you kidding?

The crowd isn't happy. Let's move onto the next one.

I'm a bit sweaty because I'm nervous.

- Cut it out. - You're so lame.

There's a hole in my armpit.

I should sew it with this thread and needle.

It's a big hole.

Wait a minute. I'm a little hungry.

- Do you have anything to eat? - No, sir.

Then I'll have to eat this thread.

- That's nonsense. - What's he doing?

- It's really gone. - It's gone.

I'm full now, so I'll get back to...

Wait. I'm sorry. It's coming out...

- He's trying so hard. - Seriously.

My goodness. There we go.

That one was good.

That was worth watching.

Good one.

Do Not Cross

Sit down.

What?

Gosh.

Go on.

What are you doing?

This was how the body was found.

This is embarrassing. It feels like I'm swearing.

Look where the finger is pointing.

That building. It looks like a church.

The cross.

The culprit used the middle finger to swear at that cross.

Her ring disappeared.

Maybe he broke her finger while trying to take off her ring.

Follow me.

Moojin Prison Magic Concert

Now it's time for today's highlight. The world-famous magician,

David Copperfield, will even be surprised to see this one.

Let me introduce the best magic trick...

you've ever seen in your life.

Can I get a volunteer for this one?

Me. I'll do it.

Okay.

Is it okay to handcuff you?

- Why would you do that? - I'm sorry.

Okay, fine. Here.

Okay then.

This man will vanish into thin air.

Okay.

Let's see.

Ta-da.

Seriously?

- What kind of magic is that? - How lame.

- Why is he still here? - This isn't it.

Let's try one more time.

Okay. This time, he'll really be gone.

I'll open it now.

- 1, 2, 3. Ta-da. - Ta-da.

- What is that? - What happened?

- What's that? - My gosh.

What's the matter with him?

Stand behind me and watch.

When we got here,

his arms were tied together at the back like this,

and his finger was also pointing up.

But his body was burned.

He was completely burned, but his finger was still pointing up.

That means his finger bone was already broken.

Plus, Song Soo-ho didn't even wear any rings.

The culprit broke his finger on purpose.

Look here.

The scratch is below the ashes.

That means he moved the chair before he burned the victim.

That window was open when we got here.

According to the people who work out here,

they never opened that window because it was broken.

You're saying the culprit opened it?

Now come back here and look where the finger is pointing.

A cross.

Exactly. The culprit opened the window,

and moved the chair to a place where the cross was visible,

so he could give it the finger.

Then he set Song Soo-ho's body on fire.

It's like he wanted the cross to see it.

The two cases have another thing in common.

He took trophies.

You mean the toy ring that was taken from Byun Soon-young's finger?

Her daughter bought it as a gift for her birthday at a stationary.

But he didn't take anything from Song Soo-ho.

It didn't say anything on the case report.

We missed something.

There's something missing from here. Try to find it.

How would I know?

Something precious.

Could it be those boxing gloves?

Song Soo-ho used those gloves...

up until the day before he died.

He wore them to spar.

The day his sister, Song Soo-jung, got those gloves for him,

she was killed by the Head Hunter.

Those gloves had a sad story behind them,

so he treasured them as much as his own life.

The fact that the culprit took trophies means...

the two cases were committed by a dangerous psychopath.

People like this culprit think of murder as a hunt.

He might even be hunting someone right now.

- What happened? - What's wrong with him?

My goodness.

My gosh, what happened?

Chi... Chi-kook!

What's going on?

Help! Help!

Officer Na is severely injured. Please come to the assembly hall.

I think someone got hurt. I'll see you later.

What happened?

Help!

- Is he dead? - Give me that.

Turn on the lights!

- Turn on the lights! - We need a doctor.

- I already called a doctor. - Breathe, Chi-kook.

- Chi-kook. - Help!

Wake up!

Give me the thread and needle. You used it for your magic trick.

It's him. The Head Hunter.

Don't touch him! Don't touch him. Go away! Get away from him!

Why isn't the doctor coming? Tell him to come right now!

- Over here! - Hurry!

- Come on! - Hurry!

Excuse me.

I think we should take him to a big hospital.

There's too much blood coming out of his brain stem.

If I don't treat him now, he'll die.

I'm not a brain doctor. I don't know what to do.

Are you saying we let him treat my friend?

That's too bad. I thought I'd use this chance to practice my skills.

Help him.

Father.

Father, don't you know who he is?

Let's trust him.

He's the only person...

who can save Chi-kook right now.

Turn him around.

In the name of the Father, and of the Son, and of the Holy Spirit.

Let me get this straight.

A psychopath...

who hates deities, religions, and the cross,

hunted Song Soo-ho and Byun Soon-young for no reason?

No.

There's a clear motive for murdering Song Soo-ho.

A motive?

Song Soo-ho was burned to death,

but according to the autopsy, his bones were broken...

in his skull, ribs, thighs... All over his body.

He was beat severely before he died.

The dirtbag hit him in the most painful parts of his body.

It was bad enough to detach all the cartilage.

It must've been excruciating.

Please...

- It was probably so painful... - ...kill me.

...that he begged to be killed,

but the dirtbag didn't give him his wish.

He watched as he suffered in pain,

until the moment he died.

The motive for murdering Song Soo-ho was revenge.

It was filled with rage.

Revenge? Do you have proof?

I found conclusive evidence.

The Holy Bible

The lab results showed...

it was saliva mixed with Song Soo-ho's blood.

As in, it came from his mouth.

Right. He'd placed it on Song Soo-ho's lap.

Why do you think he did that?

To show him that Bible verse.

He may have made him read it himself.

"Eye for eye..."

Hurry.

On three.

Right index finger.

Is that the severed finger?

Left middle finger.

That's only one finger.

There are two severed fingers. Find the other one.

I'll look.

After killing Song Soo-ho,

he placed the Bible...

back here.

He didn't put it upside down...

by mistake.

He wanted it to be found,

or he was enjoying himself, seeing whether or not we found it.

"Fracture for fracture."

"Tooth for tooth."

This means the killer did to Song Soo-ho...

as Song Soo-ho did.

Did Song Soo-ho burn someone to death that the killer knew?

Who knows?

Everyone said Song Soo-ho wouldn't hurt a fly.

You never know how people are deep down.

Anyway, did you find Han Seo-joon's son?

What?

What I asked.

That's...

I reported it to my station manager, and he said not to sensationalize.

Fine. I'm still looking anyway.

What'll you do if you find him?

Will you harass him in Han Seo-joon's place?

I understand how you feel, but must you find the son too?

What did the son do wrong?

What did the son do wrong?

What did I do wrong?

At least his dad's a murderer.

My mom and dad were good people who didn't need laws.

What I'm getting at is...

I'll make his son carry it too.

The horrifying memory I'll carry with me my whole life.

I'll make him carry it too.

That's only fair.

That's the only way it'll be eye for eye, tooth for tooth.

- Detective Ko. - Why?

I know you say that,

but you would've found him by now if you tried.

You're intentionally not looking.

If you kill Han Seo-joon in front of his son,

a new Ko Moo-chi will be created.

You're saying you'd do that?

Yes, I will.

I'm curious...

what he's doing and how he's living.

Why did you save me?!

I've lost all my babies! Why did you save me?!

Goodness!

Soo-ho!

If you want to die, cut deep right here next time.

You must cut at least an inch deep. That way, you won't fail.

Or sever an artery.

You can just cut off your arm.

That way you'll die for sure.

Doctor.

That's a bit...

How could a doctor say that?

- Stop that, Dong-koo. - Get off!

Apologize to her, you jerk.

Why must I apologize?

- Why, you...! - Stop it.

No, don't. Don't do it.

Don't do it.

If we weren't at a hospital...

- Soo-ho... - I'm sorry.

My baby Soo-ho...

Who's my next patient?

- Over here. - My baby.

Excuse me.

I don't know what happened,

but I'm sure the doctor is just very upset.

I'm sure that was just his way of telling you to be strong,

and to hang on.

Excuse me! I have Na Chi-kook's finger.

- Prepare for surgery. - Yes, sir.

- Call Neurosurgery... - Where did you find it?

In a corner behind the stage.

Thank you.

His guardian must sign the surgery consent form.

I signed it earlier because they're coming from out of town.

Doctor. Dr. Park's surgery will last a half hour longer.

What should we do?

That'll be too late.

Dr. Sung!

Yes?

We'll bring him in for surgery.

Assist him until the neurosurgeon arrives.

I'll get ready.

Wait. Isn't there another doctor?

He has a lot of experience, so don't worry.

He's bold and meticulous.

He knows human anatomy very well.

Where he must stab to kill instantly,

or make them die slowly.

It's like he studied anatomy.

Scalpel.

He's an expert with the knife.

Sung Yo-han

Youngest Surgeon Sung Yo-han

How is Chi-kook?

The surgery went well,

but he was in such serious condition when he came... We'll have to wait.

He was given great care initially.

Who's the prison doctor?

Well, an inmate who was a doctor happened to be on the scene.

Han Seo-joon.

Han Seo-joon? Han Seo-joon...

That Head Hunter?

Yes.

He was there?

- He was lucky. - Gosh.

Patient: Na Chi-kook

They caught the culprit.

Really? Who was it? Who did it?

Well, it was one of the inmates who follow Han Seo-joon.

He confessed he did it to teach Chi-kook a lesson...

for disrespecting the Head Hunter.

We're checking to see whether Han Seo-joon ordered it.

- What class do you have tonight? - English.

I'm hungry. Let's eat something.

Come out. It'll pour.

Come quickly.

Why won't you pick up?

I'll just have to cross it myself.

Please. No, don't!

- What...? - Die!

- Ma'am, it's me. - Die, you scoundrel!

It's me, Officer Jung.

It's Officer Jung. Ma'am, it's me.

Gosh. Officer Jung, what brings you by?

My sweet baby. Goodness.

Snap out of it, please.

My poor baby.

- Puppy... - What?

Puppy...

That's right. I chased him away.

It's fine.

You're all right.

You're okay now. Grandma's sorry.

I'm so sorry.

Ma'am? Ma'am!

Why, that...!

I'm sorry. I called but she didn't hear me.

I had no idea it was you.

Your bloody clothes...

had me thinking the worst.

You aren't injured, are you?

Yes, I'm fine.

You must be feeling terrible.

Your friend will recover soon,

so don't be too heartbroken.

Got it.

Good night, then. I'll get going.

How can you go looking like that?

- Wash up at my place. - No, no.

I can take a shower at home.

You can't go looking like that.

What if you run into the old ladies in the neighborhood?

You'll end up putting nails in their coffin.

- Come on in. - But...

- I'm fine, ma'am. - Come in and wash up.

- But... - Come on.

- Ma'am, please. - Let me wash that for you.

Gosh. Ma'am, let me.

Here.

This looks delicious. Thank you for this.

Well, eat up.

How many times must I tell you,

I was held up making kimchi at Ddong-gu's?

You were probably enjoying the pork that was served.

Must you put it that way?

Whatever. There's nothing wrong in my staying back...

to enjoy some pork.

On your own, though? I like boiled pork too, you know!

What's wrong? You're barely digging in.

Is it because of your friend?

All the more reason for you to eat up.

That'll lead to the speedy recovery of your friend.

Have some of the rolled omelet.

I made it especially for you...

with extra cheese.

I'm not a big fan of it.

My goodness. I love how you enjoy the food you eat.

What's the big deal when we all enjoy food?

I see.

Did you get hurt?

I see you scraped your skin. It must sting.

It'll get infected, you know.

Let go! My injuries are none of your business!

- I'm done eating. - Bong-yi.

That imbecile. You won't eat more?

- I'm done! - Unbelievable.

You're a real pooper, aren't you?

You should be starved for days on end...

to truly appreciate...

So...

You see.

That's not who she is. She might act that way,

- but she has a huge heart. - Of course.

- Anyway, dig in. - Right.

You know,

that's just because she's shy.

She gets timid, you see.

Timid? Why?

Unbelievable. The man she likes was sitting right in front of her,

and then you took her hand in yours.

How couldn't she blush?

Ma'am, please. That hardly seems like the case.

Wait.

Have you thought about what I said to you?

Ma'am,

I can be arrested for that.

Can you cut it with the jokes?

The neighborhood elders have the wrong idea about us.

- This isn't a joke. - Come on.

Think of Bong-yi's age.

She's only 18!

Why would you shed a year off her age?

She's 19 now, you know.

Also, she may seem...

skinny with no curves,

but she has the goods.

- Are you saying she's smart? - No!

You know, the goods.

She has curves.

She's curvy like an hourglass.

Thank you for the meal. I'll get going now.

I really should.

- Here. - Thanks, I'll get that.

Just so you know, this isn't a joke.

Seriously think about what I said.

Sure.

Okay, let's say he killed Song Soo-ho out of vengeance.

What about Byun Soon-young?

There didn't seem to be any emotions behind her murder.

It seemed random.

Just like the Head Hunter, the killer's a pure psychopath.

His instincts got the best of him.

A psychopath.

Psychopath

Daniel Lee Who Identified the Psychopath Gene

Daniel Lee?

Daniel Lee Not Awarded the Nobel Prize

Daniel Lee's Journey to Being Nominated...

for Nobel Prize in Physiology or Medicine

The list of 24 candidates was announced.

Edmund Kemper shot his grandparents in the head,

and then sliced them with a knife.

Wanting to know how it'd feel to shoot his grandmother...

was why he killed her.

His first killing woke up the killer in him.

The consciousness of a psychopath...

lays dormant on a subconscious level,

and explodes when met with a trigger.

The killer, for reasons unknown,

murdered the boxing gym trainer...

out of personal vengeance.

That triggered the killer in him to rise,

which led to the random killing of the hostess-bar employee.

The cool-off period will shorten,

and his killings will become bolder.

It seems to me he's just getting started.

There could even be more victims...

than the ones we recently discovered.

What's this?

Last night at a reconstruction site in Guoh-dong,

the body of a homeless man in his fifties was found,

and the police are investigating the case.

The body had been decomposing a while,

and the police estimate the time of death as 15 days prior.

Before it's too late, we must investigate these cases...

with the possibility of their being serial.

The killings won't stop.

If the killer is truly a psychopath,

even at this very moment,

he'll be hunting for his next victim.

I'm not in my best condition today.

It's why I'll be choosing an easy prey.

Someone petite...

who'll obviously lack strength.

How ideal.

To say that the one who killed the boxing gym trainer,

and the one who killed the bar employee are the same,

is still somewhat of a stretch.

However,

what if the culprit who killed the boxing gym trainer...

also killed that woman who was found in the drain?

What if the culprit is really a psychopath?

Then we must stop him to prevent more innocent people...

from being murdered.

Zodiac, the serial killer of the century,

wrote this on the very last letter he sent...

to a broadcasting station.

"Please help me."

"I cannot stop myself."

If this culprit is also a psychopath like him,

he might desperately be seeking our help.

Sherlock Hong-ju

Good work, everyone.

- Good work. - Good work.

Come on. Let's go.

Zorro, where are you going?

Zorro, come back here.

Where did you go?

I don't think Officer Jung is fit for this job.

I agree.

Do you think this cat was killed by the same guy?

It has no teeth.

You're right. It seems it's been a while since it died.

This hasn't occurred as frequently as before, right?

Maybe he moved.

- Officer Jung. - Yes?

You get nauseated over a dead cat.

You'll completely lose it if you see a dead body.

I'm sorry. I'll try harder.

You can't work on this kind of stuff.

If you go to the office,

you'll see some leftover posters in the cabinet.

I want you to post them all around the neighborhood.

Look at how slow he is.

- Get moving! - Yes, sir.

On the 13th of last month, a female was reported missing...

after having disappeared while she went out for a walk.

However, she was found dead...

My goodness gracious.

You'd better not stay out late.

How can I do that? I'm a senior in high school.

Gosh, cut the nonsense.

Eat up and wash. We'll be late to mass.

It's Father Ko's last day at our church.

I heard he's attending a church in Yirye-dong or something.

I'm busy. I'm going to the library with a friend later.

My goodness.

People might think you always get the highest grades in school.

My gosh, what if I do get the highest grades?

It's not like you can afford to send me to college.

I see. Do you always get the lowest grades...

so I won't have to pay for your college tuition?

My goodness, what a thoughtful granddaughter.

I won't tell you to study, you brat.

Just make sure you graduate,

and please just think of a way to marry Officer Jung.

Don't be so cranky whenever you're around him.

Grandma, I'm so sick of hearing you talk about him all the time.

Do you even know how much older he is than me?

- What? - Don't make me marry an old man.

"An old man"? What's the matter with you?

He's only in his twenties.

- That means he's old. - My goodness.

Let's be honest. He's the best guy out there.

He's like a cute little chestnut.

He's so handsome.

A chestnut, my foot.

He looks so weak.

It doesn't even take much to fight guys like him.

I can easily knock him out with the side of my hand.

You brat. Is that all you ever think of?

You can search everywhere.

You'll never find a man like him.

He's kind, handsome, and polite,

and last time he even won...

a citizen prize.

Back when I collapsed while collecting waste paper,

he suddenly showed up,

carried me on his back and started running like crazy.

If it weren't for him,

I'd already be dead by now.

Why did he run like crazy?

He could've just called 119.

If you're dumb, you end up exhausting your body.

You mean brat.

Even dogs are left to eat in peace. Don't hit me when I'm eating!

Dogs at least wag their tails,

and show you how much they care.

She never stops talking about Officer Jung.

Police

Eo-bong-yi. Hey, Eo-bong-yi.

Eo-bong-yi. Wait.

Pronounce my name properly,

or I'll pull your tongue out and use it as a jump rope.

It's not Eo-bong-yi. It's Oh Bong-yi, okay?

Okay. Show this to your school friends,

and if there's a witness, tell them to call the cops.

You still haven't caught the culprit?

We pay taxes so you guys can get paid,

but you're always slacking off.

I can't believe you still haven't found...

the psycho who kills cats and pulls out their teeth.

It's been months.

It's because there are no witnesses.

Take this.

Sarang Pharmacy

Your wound will get infected if you don't treat it.

Mind your own business, okay?

Hey...

Ma'am.

Hey, it's my grandson-in-law.

Are you here to see me?

Yes, hop on. I'll take you to church.

I don't think I'll be able to go to mass today.

I need to visit Chi-kook after I drop you off.

Father Ko will be upset.

He cares for you so much.

Ma'am, are you injured?

What? No, I'm okay.

My leg feels a bit numb.

- Gosh. - My goodness.

Let me see.

Ma'am, this...

What happened?

You fell on your way to pick up Bong-yi, didn't you?

Is that why you were late?

- Well, you see... - Bong-yi thought you were late...

because you were caught up eating pork.

Goodness, don't tell her about this.

If she finds out I got hurt, it'll only worry her.

Okay?

My goodness. Ma'am, try to move your ankle.

Can you move it?

No, it hurts.

Okay, you can stop.

Your bone seems fine.

You just tore a ligament.

You also got hurt here.

If you don't treat your wound, it'll get infected, you know.

My gosh, this is so upsetting.

It'll sting.

Isn't it cute?

This is Goat Man. This character is the bomb.

The kids love him.

With this Band-Aid,

you'll become a fashionista in this neighborhood.

What?

This goat will make me become a what?

A fashion what?

I'll go.

What? Go where?

I'll pick up Bong-yi whenever it rains,

so you just stay home.

My goodness, that's absurd.

I can't make you do that.

You're busy enough working for the government.

Gosh, don't think that way.

My job is to care for the residents.

Bong-yi is a resident, and so are you.

Really?

Then will you do that for me...

until my leg gets better?

Sure.

Why can't Bong-yi cross the bridge when it rains?

What? Well...

That's because...

Unlike how she seems,

she gets scared very easily,

so every time it rains,

she gets scared that she might fall into the river.

She gets scared.

What? My goodness.

By the way, Bong-yi...

- Puppy... - What?

I think I heard her say something about a puppy.

Why did she suddenly talk about a puppy?

Well, that's because...

back when she was little,

she used to have a puppy,

but she ended up losing it and went looking for it.

Goodness, we'll be late.

- Okay. Let's go. - Okay.

You're no different.

How could you ask him to be saved?

Let go of him. Don't take it out on Father Ko.

How could you go on TV and say you forgive him?

Who do you think you are?

- Father, are you all right? - Yes.

Please comfort her.

What? Forgive him? Give me a break.

What garbage.

Do you believe in God?

Student Bong-yi. It's been a while.

Did you believe in God?

Of course.

When our heart is within Him,

He listens to our prayers.

When we face trials...

and tribulations, He saves us.

That's not true. He doesn't save us.

That's why I can't stand Him...

who you believe in.

Darn it!

Darn it!

Darn it.

Where is it?

Why? I'm off today!

What?

Cash

One month until Kang Duk-soo's release

Hey, kid!

I'll see you again real soon!

Dr. Sung Yo-han?

Someone wants to meet you.

Song Soo-ho's gloves.

Byun Soon-young's ring.

That homeless man was missing a shoe, right?

We checked, and it's his.

Whose watch is this?

Inmate 4440. You have a visitor.

You wanted to meet me?

I was curious...

how much my son grew up.

There's no church or a cross.

There's no sign of the body being moved.

Stop.

He drew a cross in here,

and stuck her finger in.

Take her away.

Bingo!

Bingo! Detective Ko Moo-chi! Great deductive reasoning!

I hope you like your gift!

Personal items of the recently-murdered gym owner,

female worker, and unidentified homeless man...

were found at the scene.

The police are treating this as a serial murder,

and will form a special team to investigate this case.

My mom said...

there was another child who had the monster gene.

In addition to the personal items of the four victims,

they found a man's watch.

The police deduce there's an additional victim.

I've always wondered...

what happened to that child.

Did he become a predator like me?

Or did he become a normal person unlike me?

Mouse

Last night, I... That's not it. So...

You really think I did that because I like you, don't you?

- Bong-yi! - It must've been heavy...

with an adult man inside.

Go inside.

Me? Okay.

Chi-kook's watch was found at a murder scene.

What? Whose watch?

I want to learn from you. Let me join the investigation.

How did you know? It's still classified.

Detective. What is this?
