(Filming was in compliance with COVID-19 guidelines...)

(and counselling was provided for child actors.)

(CGI was used in most scenes that include animals.)

Give it back. It's mine.

If you let it live, you'll end up like that rat snake.

Is that what you want?

(Mouse)

What did he say?

What's wrong? Did something happen in there?

It wasn't Han Seo Joon.

What?

Han Seo Joon didn't tie those knots.

- That knot... - I never used that knot,

learned it, or taught it...

to anyone.

He never learned it from anyone, taught it,

or shown it to anyone.

And you believe his lies? How gullible are you?

Han Seo Joon didn't tie those knots.

The knot on the mouse's head was tied to the right.

But this... It's tied to the left.

There's a knot tied on a mouse's head?

Guard!

Mr. Kim!

Darn pervert.

What on earth did he do to the mouse's head?

Look. It's tied to the right.

If it were the same guy, the knot would've been tied...

in the same direction even if it's a variation.

All the records we have of Han Seo Joon's surgeries...

are the ones studied by students.

He's a lefty,

so why are these knots tied to the right?

Some surgeons are like that.

You see it with baseball players too.

Some lefties bat on the right side.

It's just like that.

It wasn't Han Seo Joon who killed Park Doo Suk's daughter.

There could be two scenarios. Either it wasn't Han Seo Joon...

or another person tied the knot instead.

An accomplice?

(Daughter of the Lead Detective in the Head Hunter Case Found Dead)

(Another Victim of Head Hunter is Found)

Tie her up before she wakes up.

(Woman Found Dead by Her Husband)

(Daughter of the Lead Detective in the Head Hunter Case Found Dead)

Judging by the dent in the tree...

and the car's broken tail light,

the accident must've been staged to lure her.

Don't you find this odd though?

What do you mean?

The taxi driver testified...

that this is where he let Song Soo Jung off.

There was a telephone booth here at the time.

Song Soo Jung called her brother from here.

A car accident didn't need to be staged...

for him to grab her from here.

How did he get her to the crime scene then?

Car accident or not, no one would easily...

follow a stranger way past midnight.

Especially a woman. And it was snowing that night.

What if...

there was someone she would've let her guard down for?

So there was an accomplice.

Let's check the precinct that got the original call.

They'll have a record of it.

(December 5, 1994)

What's this?

A witness? This wasn't written in the notes.

I didn't think a man with a kid...

would be going around slicing people's necks,

so I didn't bother to report it.

- A kid? - You see,

not many cars travel on this road.

But I saw one that day.

I know all the cars in the neighbourhood,

and it wasn't from around here.

I couldn't see the driver because of the headlights,

but there was a young boy in the passenger seat.

A young boy?

This one is a bit clumsy.

As if a child tied it.

He seemed around 10 years old.

Han Seo Joon didn't have a child back then.

I know.

There aren't any young boys who disappeared around that time.

Are these all the children that went missing?

- None are left out? - No.

Could Han Seo Joon have used the kid to lure his victims?

What if he grew up to be the next Han Seo Joon?

Thinking about that possibility gives me the chills.

It's still only a possibility.

Let's first look for a man in his 30s...

who is linked to both victims.

(Kang Min Joo, Hong Na Ri)

(Jo Ho Young)

There aren't any men that the victims knew...

who are from an orphanage...

or who could be suspected as Han Seo Joon's accomplice.

Between Kang Min Joo and Hong Na Ri,

nothing overlaps.

I just don't get it.

I'm sure it was someone who knew both of them.

- Someone they knew? - Yes.

A security footage shows...

Kang Min Joo getting in a car while smiling...

and there were no signs of forced entry at Hong Na Ri's house.

She opened the door for the killer.

It means they knew each other.

No.

It has to be someone irrelevant.

The culprit enjoyed killing people.

If I were the culprit,

I wouldn't target someone I know.

Why? Because I'd want to enjoy the process without getting caught.

Officer Jung, you fool.

Then what if you were the victim? Would you get in a stranger's car...

with a smile on your face?

And if you were a woman living alone,

would you welcome a complete stranger into your house?

- I mean... - I'm sure there's someone...

they both know that we're not yet aware of.

Let's start over.

We need to go back to the beginning.

When you're stuck, it's best to start all over.

What? You're right. Someone really did touch this.

See? I told you.

There.

Who is she?

She got reinstated a month ago,

but she's still waiting to get assigned to a post.

(Another Victim of Head Hunter is Found)

(Daughter of the Lead Detective in the Head Hunter Case Found Dead)

(Hong Na Ri, Kang Min Joo)

Why are you investigating this?

It's nice to see you're healthy.

Good to see you, Officer Jung.

Why does my heart ache all of a sudden?

I'm sorry. I didn't mean to deceive you.

Don't you know what happens if you mess with the evidence?

You were caught on CCTV, so don't even try to deny it.

I saw a scar on Hong Na Ri's wrist...

while looking through the case photos.

I could tell that her hands were tied together with something.

So I went to her house to check what it could've been.

And there, I overheard you guys talking to each other.

The pattern is different from when Kang Min Joo was murdered.

Kang Min Joo was abducted, murdered, and found in all different places.

- So I wanted to check the knot. - Why would you do that?

Here you go.

Does it have anything to do with that?

Yes, I wanted to check if the knots that were used...

to tie Kang Min Joo and Hong Na Ri's hands...

were the same as the one that was used to tie the hands of...

- that detective's daughter. - How did you know that?

How did you find out that the two knots were the same?

Back when I was getting ready to shoot a documentary...

regarding the death penalty,

I saw the knot that was used on that kid.

I still remember it because the knot was very unusual.

And I started investigating after I recently saw the same knot.

Quit lying to me.

The press knows that Kang Min Joo's hands were tied together.

But we never revealed the knot itself.

So how did you find out?

You'd better tell me the truth.

I didn't see the knot used on Kang Min Joo.

(A month ago)

Kang Min Joo might not be...

- the first murder victim. - You're so cute.

The murders probably started a month ago.

Good dog. That's it.

Hey. Come here.

A middle-aged lady visited me as soon as I got reinstated.

She told me she thinks her daughter got murdered.

Oh, hello.

The police just thought she ran away from home.

- They thought she ran away? - Yes.

Even though the dog was dead and hanging from a tree?

Apparently, Kim Young Hee had been suffering from severe depression.

So the police thought she killed her dog...

and disappeared due to her depression.

Then they filed it as a runaway case and ended the investigation.

They thought she just ran away even after they saw the knot?

No, it wasn't here.

On the day of the incident,

a handcart went missing from the park.

The culprit probably didn't know...

that the knot came loose because the dog gnawed on it.

The knot was found in here.

The police didn't see it...

because it's located quite far away from the park.

You should've taken it to the police as soon as you found it.

Why did you keep it for yourself?

Give it to me.

I can't give it to you just like that. There's a condition.

- What's that? - I want to cover this exclusively.

I want my show back.

So I want you to share every single detail with me...

regarding the investigation.

No, I find you uncomfortable.

I don't find you comfortable either.

I can't just do nothing while I'm on probation...

and end up getting fired.

What's your real reason?

- What? - Do you think I don't know you?

You want to catch this guy.

Why are you so eager to catch him?

Do you know a producer named Choi Hong Ju?

Yes, of course. We worked with her at your place...

back when we were trying to catch Sung Yo Han.

Do you remember?

- Then by any chance... - Yes?

Gosh, why are you so hesitant? What is it?

Did I ever have feelings for her?

What? You?

You cunning punk.

You can't do this to Bong Yi.

"Bong Yi"?

Are you talking about Oh Bong Yi, the girl you often talk about?

"Oh Bong Yi"? You're unbelievable.

You remember Ms. Choi but not Bong Yi?

You're so mean.

Do you know how much she worried about you?

It's not like I don't want to remember.

I just can't seem to remember her.

What in the world was that flashback?

Ba Reum.

- Hey, Auntie. - What are you looking for?

I'm looking for a photo album.

Like photos from kindergarten.

Why all of a sudden?

I have this vague memory of back when I was little.

Really? That's great.

I might have a few photos at home. I'll bring them next time.

Oh, really? Will you do that for me?

- Auntie. - Yes?

Why is there a bird cage here?

You used to have a bird right before the accident.

I think I slightly remember.

- Then where's the bird? - You didn't eat dinner, did you?

I made cheonggukjang, your favourite.

Cheonggukjang?

What's wrong? Do you not like the smell?

- No. - I'll get rid of it.

I'm sorry.

Your palate has changed.

You used to love cheonggukjang in the past.

Hello?

Yes, this is Jung Ba Reum speaking.

The redevelopment office?

So you think Kim Young Hee, Kang Min Joo, and Hong Na Ri...

were all killed by the same culprit?

We might find an epithelial tissue, so send it to the NFS.

Okay.

Let me catch this jerk.

What kind of trouble are you trying to get into this time?

You work in the Evidence Management Team,

not the Violent Crimes Unit.

You know I'm a violent crimes detective all the way.

How long do I need to rot in the Evidence Management Team?

I need to prove that I'm worthy in order to get transferred back.

Give me a chance.

I'll prepare everything on my own.

Don't look at me like that.

Only until the NFS results come out.

- What's wrong with you? - Thanks.

It'll be torn down before the presidential election.

Hi, Eo Bong.

- Stop it! - Bong Yi!

Oh Bong Yi. Bong Yi.

- Oh Bong Yi! - Oh my gosh.

I'm sorry.

My baby.

Officer Jung.

Please check in on that brat...

Bong Yi...

now and then.

She stopped coming to school after what happened to her grandmother.

It's sad. Graduation was just around the corner.

I give in.

Do you want to marry me?

Marry me...

once you graduate.

Where are you, Bong Yi?

Hold on. Hold on.

You poor thing.

But you need a comfortable spot...

to give birth in.

Hold on.

I'll make you a nice home.

Be patient.

I'll be quick.

Why did you call me here in the middle of the night?

- Look there. - Where?

I took these pictures at Kim Young Hee's...

and Kang Min Joo's places last night.

The home and the neighbourhood were falling apart.

The wallpaper was moldy, and there were cracks everywhere.

- But? - But...

Aren't the window bars too new?

You're right.

These are new too.

The worker who installed the bars.

So they wouldn't be suspicious if they ran into him...

And they wouldn't be identified as a common acquaintance.

The city ordered this model.

It was for women living alone in high-crime areas.

Who installed them?

They were volunteers.

It was a joint campaign with the anti-crime association.

Excuse me.

Do you raise that dog here?

Yes. The volunteers here take turns...

taking care of it.

Detective. Kim Young Hee's dog was also white, wasn't it?

Yes.

Captain. Please check...

whether the dog hairs found on Kim Young Hee's headband...

belonged to more than one dog.

Can we find out who installed it?

It was a one-time event,

so many people came to volunteer.

So we didn't record them all.

Many of our volunteers are extinguished in their fields.

- Like CEOs of corporations... - How can we tell...

where is where?

Do you have the original photo for this?

- Where is this? - Hong Na Ri's building.

How can you tell?

Here. Look.

There was a cabinet in the balcony next door,

and it had turtle stickers on it.

How did you know?

I saw it on our way out when we came last time.

- You remembered this? - Yes.

Did your brain surgery make you a genius?

Right? Dong Koo said I wasn't very smart...

before the surgery.

That's right.

(Safety for Women)

I'm Choi Hong Ju. I'm working on a documentary...

on crimes targeting women.

My daughter is in college and lives alone. I did it for her.

I have five daughters. When I hear about crimes against women,

- it hits too close to home. - I was reminded of my daughter.

- That's why I volunteered. - Isn't she pretty?

It's a girl. Thinking that I will be a dad soon,

I wanted to help any way I can to create a world...

in which all daughters can be safe. That was why I volunteered.

Thank you for your participation.

We've prepared a small gift.

My gosh. You didn't have to.

Two tied to the left.

Jung Man Ho and Kim Baek Ki.

I suspect Jung Man Ho. He was emotionless.

- I was reminded of my daughter. - Hey.

- You don't have a daughter. - And he lied.

What are you thinking about?

He cruelly killed Kim Young Hee's dog.

- And? - Thank you.

Can we do a couple of follow-up interviews?

Kim Baek Ki and Jung Man Ho.

- Okay. - And Woo Hyung Chul too.

What is it about?

They said to wait here while they set up the camera.

How cute.

They'll be here soon. Have a seat.

It's Jung Man Ho, isn't it?

He clearly hates dogs.

No.

- Woo Hyung Chul? - I'm sure of it.

Look.

Kim Baek Ki, Jung Man Ho, and the other volunteers...

made the same gestures.

But...

Woo Hyung Chul's are larger and more exaggerated than usual.

Especially here.

"I wanted to help any way I can to create a world..."

"in which all daughters can be safe." When he said that,

his hand gestures were big as if he's putting on an act.

Like he's explaining something he doesn't understand.

Isn't it unreasonable to judge based solely on hand gestures?

That's why I checked again to be sure.

Can we do a couple of follow-up interviews?

I pet the dog the exact same way in front of the volunteers.

Both sides of the neck, the side, and under the tail.

That's how I pet it.

Jung Man Ho looked too uncomfortable to even pet it.

Kim Baek Ki and Woo Hyung Chul appeared to put it endearingly,

but Kim Baek Ki pet both sides of the neck, the side,

and the back of the neck.

Woo Hyung Chul pet both sides of the neck, the side,

and under the tail.

Exactly the same.

- So what? - Most dogs...

hate being touched under their tail,

so people who really like dogs don't pet them there.

- Then why did Woo Hyung Chul... - Because of me.

Because I pet it under the tail in front of them.

Woo Hyung Chul saw me pet it under the tail...

and copied me down to the order...

and pet it under the tail too.

He mimicked my actions.

He didn't pat the dog with love.

Because a cop was in front of him,

he patted it to make it seem like he loves dogs.

I'm sure that Woo Hyung Chul is the one.

What about the knot then?

The knot was tied to the right.

He already realized that this was a fake interview.

It's why he tied a different kind of knot...

than the one previously used.

- Check this out. - The lawyer for...

This is Woo Hyung Chul from when he was on the news.

The words of the bereaved families were delivered.

Right here. He's holding the pen with his left hand.

So he is a lefty.

But the knot was tied to the right...

to make it seem like a right-handed person tied it.

Hold on. Did you study up on psychopaths or something?

What makes you so certain?

You know...

- I can just feel it. - That again?

Did you spend some time in a psychopath's brain?

I saw on the news that you were released.

It's all thanks to you, Mr. Woo.

I'm grateful.

Thanks to me?

I resigned as soon as I figured you out.

If you had stayed on my case,

I would've gotten a reduced sentence.

Why have you come to see me?

The girl.

I was wondering if you knew where she was.

The girl?

- Don't tell me... - Don't get me wrong.

- Don't tell me... - Don't get me wrong.

All I want to do is apologize to her in person.

My current lawyer won't tell me where she is though.

I only want to apologize.

I don't know.

I scrapped all documents when I resigned as your lawyer.

Even if I knew where she was, I wouldn't tell you.

I guess I have no other choice.

Because of this around my ankle,

I can't search for her myself.

Even though I want to,

I should give up on finding her.

Who's he?

Hey, Dad.

Yes, Captain.

Do you know which dog hair was on Kim Young Hee's headband?

Yes, it was from two different breeds.

Two?

Okay.

Two different breeds.

("Study on Psychopaths")

"When psychopaths explain..."

"abstract and sentimental concepts like families,"

"they move their hands more."

As if he's putting on an act.

"Beat gestures are mostly used."

Like he's explaining something he doesn't understand.

It didn't sound like something from a textbook.

Seriously. What's gotten into him?

Darn, I'm exhausted.

Nepo, lend me a hand if you're not busy tomorrow.

- Officer Jung. - Yes?

Would you like to join my team?

- Me? - Him?

He doesn't seem like the type, but he's got good detective skills.

Don't waste that at a small precinct.

Check if this hair is the same as the one found...

on Kim Young Hee's headband.

Jung Man Ho, Woo Hyung Chul, and the others.

Check their whereabouts on the day of Kang Min Joo...

and Hong Na Ri's murder and Kim Young Hee's disappearance.

Got it.

But Officer Jung hasn't fully recovered yet.

- You'd find him a burden... - I'm thrilled.

Do I get to be called Detective Jung now?

- He can't... - Come on, Detective Jung.

Lawyer Woo?

Yes, he took the dogs out for walks often.

The volunteers can take the car out.

Would you have a record of that?

- Of course. - Then...

Could I see the log for March 8?

(March 8: Woo Hyung Chul, window bars)

- Please call me anytime. - Sure.

Take care.

- Good luck. - Thanks.

Hello. Please come in.

- Please have a seat. - Who was that earlier?

He offers free consulting for runaway teenagers at times.

Gosh, your wife is stunning.

You must be getting some fun on the side though.

I didn't know you were a detective.

Anyway, how can I help you?

The log says you took the car from the volunteer center on March 8.

Where did you go to volunteer?

He came by to install security bars on my window.

I saw him often on TV, so I remember him clearly.

Moo Chi, I checked and everyone has a solid alibi.

- Are you sure? - What did I tell you?

Officer Jung hasn't fully recovered yet.

So Woo Hyung Chul has a solid alibi?

You should've listened to me, not him.

Then check the alibis for Kim Baek Ki and Jung Man Ho.

Detective, Woo Hyung Chul is the killer though.

As if.

It was only a lucky guess.

Just call those who asked for window bars to be installed.

Those we know might not be the only victims.

Darn it.

I'll make the calls.

- Did you check him out too? - Yes.

He had to get stitches for the injury.

What did you find?

I was just about to call you.

The hair you collected from the dog house...

is from a different breed...

than the hair found on Kim Young Hee's headband.

Seriously? Then he was barking up the wrong tree.

Got it.

Right. Moo Chi!

Jung Man Ho's cell phone was nearby Hong Na Ri's house...

at her estimated time of death.

Jung Man Ho?

It really wasn't me.

Why were you in the neighbourhood around the time of the murder?

A friend of mine owns a carpenter shop there.

I was there to make a tool box...

for a friend as a birthday gift.

Can someone verify that?

The shop was closed that day.

So you happened to be alone that day.

You've got to be kidding me.

Oh, wait. I took a photo of the tool box I made...

and sent it to my friend.

Show me that photo.

I deleted it.

So your phone happened to be out of storage space.

I'm telling the truth!

Do a forensic analysis on the phone then.

Give us the friend's number.

- He'll have the photo you sent. - Oh, right.

Is it under "Jae Pil" or "Hyung Chul's Dad"?

Jae Pil? Are you referring to Woo Jae Pil?

Wait. You must know him.

Now I remember.

He used to work violent crimes with the Guryeong police.

(Detective Woo Jae Pil)

He's not answering.

Hello?

In anyone home?

In anyone home?

It's me, Captain. Please put Jung Man Ho on the phone.

- Go ahead. - Sure.

I'm right, aren't I?

Jae Pil has the photo of the tool box I made.

Has Woo Jae Pil also been doing volunteer work...

installing window bars on homes?

His name wasn't on the list.

Not really.

He'd go with Hyung Chul on his day off,

but he wasn't registered with the center.

He went with his son?

Who took the photo outside Saetbyul Villa?

Jae Pil, of course. He always took the photos for us.

2, 3.

Okay, that's good.

Let's take one standing.

(Safety for Women)

It's the dad, not the son.

So nothing was out of the ordinary.

Did you see anyone suspicious?

Okay.

(List of applicants for safety window bars)

"Oh Bong Yi"?

(Oh Bong Yi, 13-1 Anshin-dong)

Anshin...

Anshin-dong.

Bong Yi.

Bong Yi.

Bong Yi, it's me, Ba Reum.

Call me.

There are no street lamps or CCTVs here.

It's too dangerous.

You're dead.

Stop, you jerk!

Shut it!

I look nothing like a thief.

Stop barking. Let me think.

It's a white dog.

What... What's all that?

Bong Yi...

Woo Jae Pil.

Did you kill those women?

Yes.

Did you also kill Detective Park's daughter, Park Hyun Soo?

Yes.

Why did you kill her?

- Tell me. - Detective Ko.

Get off me.

- Talk if you don't want to die. - Detective Ko, calm down.

- Detective Ko. - Moo Chi, put that down.

- Tell me why. - Hey.

- What do you think you're doing? - Get off me!

Jerks like him deserve to die!

- Let go of the gun! - He killed Park Hyun Soo!

What are you saying? Calm down and explain.

Park Hyun Soo! He just admitted that he killed her!

Jae Pil, why...

Why...

Where's Bong Yi?

In the ER.

You brat.

Do you know how much I looked for you?

I can't believe you're living in that neighbourhood.

Who could he be?

I'm sure I saw him somewhere.

Where's the patient?

She just left.

We told her not to leave, but she insisted.

(Emergency Medical Center)

It rained like crazy...

on the day of the incident.

So every time it rains,

that poor child...

I'm sorry I came too late.

I'm sorry it took so long to remember you.

Let's go.

Where did you get something so childish?

Hurry up.

I thought you might not want me to come.

My arm hurts.

Let's go.

The killer who targeted only women who lived alone...

tried to do it again in Anshin-dong.

But the woman fought back, and he was arrested at the scene.

Anshin-dong...

Hey. It's me.

Mom.

Does she live in that neighbourhood?

Why would she? She moved away years ago.

Why would she want to live here?

A "no" would've sufficed. No need to yell.

Mom. Should I...

come visit?

Why would you come here?

Please, let me live in peace.

I'll make some food and go to you.

Don't you dare come here. Okay?

(Police)

This old woman is being suspicious.

Mr. Kim.

You're off tomorrow, right?

Yes, I am.

Will you please help me?

Did you tell him?

Why do you both look so nervous?

We caught Hyun Soo's killer.

What did you just say?

Well... So...

Jae Pil.

No, right?

My girl Hyun Soo... That makes no sense.

It's true. I killed her.

What do you mean?

The Head Hunter...

kidnapped Hyun Soo.

The truth is, I found her...

when we searched the mountain for her.

She must've gotten away, and was huddled and asleep in the woods.

But?

I couldn't stand you for getting more arrests...

and how pompous you were because of it.

When I heard that Han Seo Joon had abducted Hyun Soo and Hyun Suk,

I was glad because you deserved it.

Seeing you bawl when Hyun Suk was found...

and incompetent and unable to do anything because of Hyun Soo...

made me happy.

But Hyun Soo came back alive.

So I... I just killed her.

Even if she was found later,

everyone would assume Han Seo Joon killed her.

That's what I told myself.

You scumbag!

You disgusting monster!

Die. Die, you scumbag!

Die! Die!

Die!

You scumbag!

- Let go of him! - Get off!

I hope you burn for eternity, you scumbag.

Why did you lie?

You didn't kill Park Hyun Soo.

Don't tell me...

You...

It was uncovered that the daughter of Park, a detective...

was not Han Seo Joon, but Oh, a fellow detective,

which has created an outrage.

Oh...

How dare that old hag lie to me?

- Hi, Bony Yi. - Ba Reum.

You didn't forget that we're meeting later, did you?

Of course, not. See you at the theater at 6pm.

Okay. Also...

I have a favour to ask.

What is it?

My grandma was wearing the brooch that I had made her.

I didn't get it back yet.

Detective Ko?

(Evidence Room)

(Restricted Area)

2019.

Where is it?

(Predator's Murder Cases)

It's not here.

Is it in another box?

This man...

What is this?

Why is a guy Sung Yo Han killed in my memory?

What are you doing there?

How did you get in?

That's my daughter's.

That's my daughter's. Give that back.

Give it back.

Give back my daughter's bracelet!

Why are you asking about Song Soo Ho?

I'm curious, that's all.

He was burned.

Was he also beaten...

You wouldn't know since his body was burned.

Actually, he suffered fractures all over his body.

He was beaten to the point where his cartilage got torn off,

so nearly to death.

I see.

When did she leave?

I was in the kitchen cooking when...

One of the assumed victims of Head Hunter,

the serial killer who terrorized Guryeong 25 years ago,

who turned out to be the daughter of...

- the lead detective in the case... - Ma'am, are you all right?

- Where do you live? - The real killer...

is currently at the hospital being treated for his injuries.

Why is this happening to me?

Why am I getting flashes of Sung Yo Han's memories?

You must read a lot of files...

regarding Sung Yo Han before the accident.

Probably.

I hear I investigated the case alongside Detective Ko.

You're mistaking what you read in the files...

as your own memories at the moment.

Don't worry though.

What you experienced and what you saw...

will soon be distinguishable.

I see.

But...

could that happen with childhood memories though?

Like the ones from kindergarten.

Of course.

What you read or saw in books and movies...

get confused with your own memories.

I see.

Have you been taking your medicine?

Of course.

Then, let's switch up your medication a bit.

- Here's your medication. - Right.

Take them 3 times a day, 30 minutes after your meal.

- Sure. Thank you. - Thank you.

I've seen the exact same medication before.

The suspect currently being treated in the hospital...

will be taken to the police for questioning tomorrow.

- It's now or never. - Before he's transported,

the people's complaints...

Detective, can I check the evidence in the case of Sung Yo Han's victim,

Jo Mi Jung?

It's to treat anorexia. It was found on her desk.

Hello, ma'am. I'm Officer Jung Ba Reum.

I was sorting out the case when I came across a question.

Did your daughter...

perhaps receive brain surgery?

Yes.

She was injured in a bike accident two years ago.

I see.

Do you perhaps remember the name of her surgeon?

Dr. Park Min Joon?

That's right. She didn't have anorexia.

It was to treat the aftermath of her brain trauma.

Her basal forebrain was damaged as a result of her accident...

and lost her sense of smell.

That was the reason behind her weight-loss,

but Sung Yo Han thought she had anorexia.

I felt terrible when I heard it on TV.

Then, could brain damage give you...

a heightened sense of smell too?

Why do you ask?

I'm told that I used to love cheonggukjang...

before my surgery,

but I can't stand the smell anymore.

Could that be an aftermath of my brain injury?

Of course not.

It's impossible for brain damage to make you more sensitive to smell.

Although, there is one way that could happen.

What's that?

Thank you, doctor. I'll come back soon.

Ba Reum!

Hey, Bong Yi. What brings you by?

The doctor wanted to check my wound.

- What about you? - Oh, I was here...

to see the doctor who operated on me.

He operated on you?

- Yes. - That's not him.

It is.

No, the doctor who operated on you...

was older.

What?

How would you know that?

You see...

To be still alive after all he went through...

proves his desire to live.

It's too bad, but we have no other choice.

Anyway, Jung Ba Reum's surgery...

must be a success.

(Department of Neurosurgery)

No, he's not here.

Really?

(Department of Neurosurgery)

But these are all the doctors in the Department of Neurosurgery.

Good day.

I'm here with someone who has lost her way.

She seems to be one of your patients.

Hello?

Goodness. Where is she?

Which hospital?

- Doctor. - You're back?

You see...

Are you sure you're the one who operated on me?

Of course.

Why would you suddenly ask me that though?

I was wondering...

if you were joined by someone else.

No, it was just me.

I don't want to sound like a show-off,

but I'm known as one of the top neurosurgeons in Korea.

It's what I take pride in.

I see. Sorry to have bothered you then.

- I'll get going. Have a good day. - Sure.

(Park Min Joon)

He lied.

Jung Ba Reum suspects something.

Why is he lying though?

Why?

Why is he lying?

We have an emergency.

There's an armed assailant in the lobby of Moojin Hospital.

Officers in the building, help is requested.

(Regional Emergency Department)

Just you wait, Han Seo Joon.

I'll kill Woo Jae Pil and come for you next.

Ko Moo Chi, what are you doing here?

He's not here.

The doctor had a scar on his face.

A long one on his right side.

A scar?

What on earth did he do to the mouse's head?

He used to be a hotshot neurosurgeon, right?

No way.

The man's behind bars.

Why did he have to be a neurosurgeon of all things?

Mr. Kim, it's me.

Yes, I've been doing well.

Could I perhaps get a recent photo...

of Han Seo Joon?

Recent photos of inmates can't be taken outside prison walls.

A documentary show interviewed him once.

You could watch that.

Oh, right.

Wait.

Let's say I killed him.

Help me so I can get to Han Seo Joon.

I'll take revenge on behalf of your kids.

I'll take revenge on behalf of all the victims' families.

Please.

I killed him. Arrest me.

He's dead.

What are you doing?

Arrest him.

(Police)

It wasn't him.

No.

No.

Moo Chi...

is going to kill the guy...

who murdered our kids.

I know I'm a bad guy for doing this.

But let's just pretend like we don't know anything.

Let's turn a blind eye...

just this once.

Han Seo Joon's interview?

Yes.

I noticed that his interview was edited out...

- from the documentary. - Yes.

The victims' families got very upset after the show aired,

so we deleted the interview from the documentary.

But why?

I'm just really curious.

I also kind of want to know why Detective Ko...

is so furious at him.

- I'll look for it. - Okay.

Hey, Bong Yi. I just sent you a photo.

Can you check if he's the doctor?

- A photo? - It's a screenshot of a video,

so it might not be clear.

But try to see if it's him.

You grew up into a beautiful lady.

My sweetheart.

Ba Reum, it's him. He's the guy who did your surgery.

What did you do...

to my brain?

What did you put inside my head?

Don't tell me...

you implanted Sung Yo Han's brain inside me.

Is that what you did?
