Hey! Stop running!

Hey, you. Come back here!

Hey.

Come here.

Hey, hey. Come back here.

- Come here. - We got you.

- Watch it. - Boss, we found him.

We'll bring him in.

Hey, hey, you can't do that. Don't do that.

Stop, stop.

- Who are you? - Did you join recently?

You don't know me? That's unbelievable.

Spit out your gum.

- Get them! - Darn you.

Get them!

Stay still.

That hurts.

No, no. I'm with the police.

Are you okay?

I saw it.

The murder.

What?

Well done.

We have the witness.

The Sinwol Gang was after someone.

I wondered who that could be.

Then suddenly the thought hit me.

Maybe Sinwol and Guwol are one.

Then maybe someone wants it...

to look like a revenge killing between the two gangs.

It's a nice hypothesis. That could be true.

The great Ha Tae Sik.

Why did he come to the police and voluntarily as well?

Team Leader Hwang.

That's him.

Team Leader Hwang. This is Mr. Joo Sa Gang.

She's our team leader.

You know, you turned yourself in...

to keep me here.

During the 48 hours you're detained without a warrant,

you wanted Choi Du Man to eliminate someone.

To make it a perfect crime.

However...

The person you were looking for. We found him first.

The witness.

(Tell Me What You Saw)

(Mucheon Metropolitan Police)

The killer you saw that day. Was it him?

No.

Take another look.

Are you sure it's not him?

You're safe here. Take another look.

Go on.

It wasn't him.

Take him away.

Okay.

Come with me.

Drink this.

Aren't police stations scary?

So...

Do you remember anything about the killer?

He wore a helmet.

A helmet?

A black motorcycle helmet?

I saw his face when he raised the visor.

You saw him?

What does he look like?

I can draw him.

Wait. Just a moment.

Draw it on this.

Joo Sa Gang, 21 years old.

He's studying in the US.

According to him, he's here for the holidays.

Team Leader Hwang. I looked up Joo Sa Gang and he has no record.

But he's scheduled to fly to the US tomorrow morning.

(Passenger information, Joo Sa Gang)

It's him.

- Team Leader Hwang. - What?

Joo Sa Gang drew the criminal's face.

Ask reference witnesses of Won Pyeong and Pan Geun's murders...

and business owners nearby...

if they saw a man in a helmet.

Okay.

I asked the local patrol division to protect you.

Don't worry too much.

Thank you.

And by the way, please find him.

We will.

So you're saying that night near the scene of the crime,

you remember seeing a man wearing a helmet?

Thank you.

Okay, got it.

Man Su.

Most store owners near Won Pyeong and Pan Geun's murder sites...

saw a man in a helmet.

Doesn't he look a lot like Sinwol Gang's Choi Du Man?

The scar under the eye too.

You're right.

But...

Team Leader Hwang.

This drawing looks too much like Choi Du Man.

Ha Tae Sik and Choi Du Man?

Find out about Choi Du Man's past for me.

Just a moment.

Hey.

Are you sure?

Thanks anyway.

That was a detective who investigated Choi Du Man.

Choi Du Man once did time instead of Ha Tae Sik.

Then Ha Tae Sik...

turned himself in instead of Choi Du Man?

It looks very likely that Choi Du Man's the killer.

I'll locate him right away.

Let's move it! We have a suspect.

- What? - You.

Call the phone company...

and trace Choi Du Man's phone.

Okay.

Hurry up. Get your gear and batons.

- Move it. - Okay.

Be careful.

Okay.

Choi Du Man!

He's dead.

Darn it.

Team Leader Hwang.

Choi Du Man's dead.

Okay. Tae Sung, call Forensics.

Okay.

Got it.

I'll call when we have the results.

(Mucheon Metropolitan Police)

Come in.

- What is it? - This parcel came for you.

(To Mucheon Metropolitan Police)

Ha Tae Sik.

Why did he send this to me?

(Investigation Report)

Chu Won Pyeong's estimated time of death.

9pm on the 26th.

Kim Pan Geun...

11:30pm.

When Chu Won Pyeong and Kim Pan Geun were killed,

Ha Tae Sik...

was in his office all along.

He turned himself in, sent me his alibi,

and now wants me to let him go?

This punk.

Is he making a fool of the police or mocking me?

Choi Du Man.

I know you two had a special relationship.

I also know he did time instead of you.

You can't stand to be in one's debt...

and wanted to make up for it.

You're right.

Choi Du Man is dead.

Ha Tae Sik...

turned himself in to cover for Choi Du Man.

To take the blame for the murders.

No.

In that case,

why did you need 48 hours?

Tell me.

Everyone...

has a secret they want to hide.

So, what is that secret?

Five years ago,

at Junggeon Three-way Intersection.

There's a secret.

What could that secret be?

What are you saying?

I told you.

I have a condition.

What is it you're hiding?

If you find out,

I'll tell you something you want to know.

Tell me.

What are you doing?

- Let him go. - I can't do that yet.

The real killer's dead!

Ha Tae Sik has an alibi.

(Mucheon Metropolitan Police)

(Police)

He completely changed his story.

Why do you think he turned himself in?

I wonder too.

Everyone...

has a secret they want to hide.

Ha Tae Sik.

What is it that you have?

He came here with everything planned out.

(Crotalotoxin)

The poison.

The button.

Choi Du Man.

What he didn't plan for...

The witness.

(Mucheon City)

I saw this signature somewhere.

Cha Su Young. Find out about Joo Sa Gang.

Joo Sa Gang?

He has a connection with Ha Tae Sik.

Give me Joo Sa Gang's statement.

Here you go.

Ha Tae Sik and Joo Sa Gang?

Ha Tae Sik and Joo Sa Gang?

There was a painting in Ha Tae Sik's office.

There was also one in Choi Du Man's office.

There were paintings?

Keep going.

Both had the same signature at the bottom.

Look at this.

The signature on the witness' drawing.

It has the same capital S.

I'm positive that Joo Sa Gang painted them both.

Good job. Bye.

When Chu Won Pyeong and Kim Pan Geun were killed,

Choi Du Man had an alibi.

That means he isn't the killer.

Ha Tae Sik and Joo Sa Gang...

have another connection, one that isn't too ordinary.

Ji Min, get me Joo Sa Gang's address.

Okay.

81-9, Haewol-dong, Dongcha-gu, Mucheon City.

But it looks like an old address.

Keep digging.

Okay.

It's close to where we picked him up.

Hyun Jae, get over there with Su Young.

You two, track Ha Tae Sik.

Okay.

I think it's this building.

(Meliana Art Supplies, 27-15, Namji-gil, Namji-dong)

Come here.

The paintings...

Joo Sa Gang wasn't just a witness.

What is he then?

Ha Tae Sik bought Joo Sa Gang's artwork.

He knew Sa Gang even before that.

Choi Du Man hung his painting in his office.

That means Sa Gang lied...

when he said he didn't know the two.

That's right.

There's a letter after the signature.

Each painting has a different letter of the alphabet.

It's an Easter egg.

What does it mean?

Su Young.

You said there were paintings at the murder scenes.

Yes.

The painting in Ha Tae Sik's office...

and the one in Choi Du Man's office also had a letter.

Remember all the letters.

The painting in Ha Tae Sik's office had an A.

The one in Choi Du Man's office had an F.

This has a T.

This says H.

Here's an E.

And an R.

That spells out A, F, T, H, E, R.

In the order of deaths, it'd be T, H, and E.

And this would be the last R.

It's an anagram.

(A word formed by rearranging the letters of a different word)

Father.

Don't you think the paintings here...

are of the victims of this case?

That face and the scarf...

remind me of Won Pyeong,

and the red shirt and black suits...

remind me of Pan Geun.

The dead man sitting on a chair...

looks like Du Man.

This painting looks like...

it's of a man hanging from the ceiling.

They're all paintings of dead men and are of the same collection,

inspired by real murder cases.

A murderer who paints his murders.

Who's the man with the helmet...

that Sa Gang mentioned?

If my predictions are correct,

the murders were predicted.

The last victim is...

Tae Sik.

Get in quick! We found Tae Sik's car.

It was caught on a camera near an abandoned distribution center.

Please save me.

This is what you wanted.

No.

You piece of trash.

You're so unconfident and have no opinion.

People as weak as you are useless!

But he's still my father!

Your mother died right in this container,

shivering in cold.

That man killed her.

He killed her so that he can live.

Kill him with this.

It's okay.

Kill him.

What good is a family?

Wake up.

He's the man who made you like this.

Team Leader Hwang, Sa Gang's mother is Seon Hwa,

who was found dead in a container in 2004.

Sa Gang, who was five years old at the time, lived,

and it's estimated that his mom died while sneaking into Korea.

She died while sneaking into Korea?

Mom! Wake up!

Come here.

And the person who registered Sa Gang is Jin Chun Gil.

I looked up who he is...

and that's Tae Sik's former name.

So Sa Gang is Tae Sik's son.

To take revenge for his mother's death,

he has been killing people around Tae Sik all along.

Tae Sik has been ordering someone...

to forge evidences.

All of that was...

to have Sa Gang exit the country.

That's why he turned himself in,

because he needed to stall time.

48 hours.

Then who's the man in a helmet...

that Sa Gang...

and the neighboring merchants reported to have seen?

Your son had to watch his mother die.

Then he told himself...

that he'll make sure to get revenge.

You can...

stop now.

Next up is your son.

No.

Don't kill Sa Gang.

He's helpless.

Are you trying to act like a good father now?

This is all because of money that you loved so much!

You made your son this miserable.

Stop it now.

Isn't this Tae Sik's car?

This is like finding a needle in the sand.

- How are we going to find him? - Let's divide and conquer.

- We'll go this way. - All right.

Where have I...

seen this logo before?

(CT Delivery Haewol Branch)

I saw it in Sa Gang's notebook.

Su Young.

Why?

91W?

91W?

M16.

It's M16.

What do you mean by that?

I saw a sketch...

in Sa Gang's notebook,

where a man was hanging upside-down...

and beside him, there was this logo...

and a sign labelled 91W.

- And? - If I rotate the drawing...

upside-down like the painting we saw earlier,

91W becomes...

M16.

M16.

It must be Zone M.

Here is P and here is L. Then M.

It's this way.

You piece of trash.

You're so unconfident and have no opinion.

People as weak as you are useless!

So have you decided?

I can't. I can't do it.

What do you mean, you can't?

You have to do it yourself this time.

No. I can't.

You idiot.

This is what you've wanted all along.

Don't just order me around and kill him yourself this time.

Hyun Jae.

Sa Gang.

Kill me if that's what you want.

If you don't, I will.

Look. This is the man who made you who you are.

I found Tae Sik,

but Sa Gang and the helmet man are nowhere to be seen.

Get him!

Team Leader Hwang, we're chasing the helmet man.

I'm around Zone L.

All right, I'll be there soon.

Did you find out about my secret?

Yes.

Your ultimate goal was...

to have Sa Gang leave the country.

That's why you turned yourself in.

You made sure that all the attention was on you,

so that you can stall time,

even if that meant that you had to forge evidences.

This was all because...

Sa Gang is your son.

As expected of you, Hyun Jae.

Su Young.

Where are you?

- Are you all right? - Yes.

Sa Gang?

Due to his trauma, he created another identity.

It's the man in the helmet.

He's Tae Sik's Achilles' heel.

I couldn't...

stop him. He's my son.

You're running out of time.

Listen carefully.

Junggeon Three-way Intersection.

4, 7,

eight,

nine.

4, 7,

8, 9.

Are you all right?

Sa Gang.

You're under arrest...

for being responsible of three murder cases.

You have the right to hire a lawyer...

and refuse to respond to our questions.

You also have the right to...

appeal to the arrest.

Let's go.

Hold on.

Father.

Hold on.

Father.

Father!

Father...

The helmet man is...

Sa Gang's another self that he created out of trauma.

It wasn't him.

Who are you?

Tae Sik turned himself in,

so that Sa Gang would have enough time to flee the country.

Even someone like Tae Sik...

didn't want his son to become a murderer.

That was the secret all along. We almost missed it.

Not all truths can be seen with the eyes.

If not everything I can see is true,

then what am I supposed to see?

What people really want to say.

Then what?

Then you'd be able to see everything as is.

Good work, you two.

(List of unresolved cases)

(To-do list)

(Strongest Engine used car rentals)

Strongest Engine is the last one on the list.

(Address of Strongest Engine)

(Junkyard in Jungmyeongil-dong, Jung-gu, Mucheon)

(Employee ID Issued by the Prosecutors' Office)

Why?

Why do you want to join the RIU?

There's someone...

that I need to find and arrest, just like you.

Excuse me, sir.

Who are you?

I heard that this place used to be Strongest Engine...

that rents out used cars.

Could I meet with the employees or anyone who worked here?

Well, after the owner died,

the business went out of business a long time ago.

Right. So it doesn't have to be the owner.

I was wondering if I could meet with anyone who worked here.

Stop being a bother.

I don't know anything.

I'm a detective from the Regional Investigation Unit.

There's someone I must find.

You're a detective? All I did...

was hand over the car key.

I didn't do anything wrong.

Does it mean you worked for Strongest Engine?

I'm not here to see who made mistakes.

I just want to find out more about a license plate number.

It's Mucheon 11, A5897.

(Mucheon 11, A5897)

A lot of people came here to pick up their cars.

How can I remember all of those cars?

Sir, I became a detective to find out about this plate number.

I mean, why is this plate number so important?

This vehicle hit my mom and ran away.

And my mother passed away from the accident.

I looked into all of the illegal vehicles in Mucheon.

This is the last stop on my list.

Please I'm begging you.

Gosh. You know what those illegal vehicles are?

Sometimes, there could be dozens of people...

registered under one license plate number.

Your story is heartbreaking,

but there's nothing I can do.

Well, anyway, give me your phone number.

If I find out anything, I'll call you. Okay?

This is my card.

(Cha Su Young)

- Thank you. - Sure.

(Mucheon Metropolitan Police)

How can you fail to catch him? Look at the mess you caused.

How dare you make us to be the laughing stock?

If you can't solve this case, it's the end for all of us.

It's the biggest case the president is interested in.

Where can we catch him?

We have no evidence. And we don't even know who he is.

The cop who lost him committed suicide...

because he couldn't stand the criticism.

Then, who will take the responsibility?

We must catch him no matter what.

If you don't catch him by the end of this month,

prepare yourselves to resign!

We're about to lose our jobs.

We must survive no matter what.

Or turn this into our chance.

Go in there. Search everywhere.

- Yes, sir. - Yes, sir.

What's happening?

It's me.

Let's make a fall guy.

"4, 7, 8, 9".

A new clue.

We must find out what the clue means.

If he's the Second Senior Chief,

he's the third most powerful officer in our station.

Chief Choi... I mean,

Senior Chief Choi got promoted super fast.

He's going to have all the power he wants here.

And we'll disappear into the ground.

My gosh, why do you say that? We can aim for the sky.

How? With wings?

Anyway, he's so lucky.

He stood out from his colleagues...

and got on the higher-ups' good side.

He became the Second Senior Chief.

- Hey, how does this make sense? - Over there.

Congratulations, sir.

It's all thanks to you.

- Congratulations. - Sure.

It's cold out here. Why are you here?

- Congratulations, sir. - Thank you.

- Congratulations, sir. - Sure.

You helped a lot.

I hope you will continue to help me.

I'll keep doing what I've been doing.

I don't think you should.

You should try to do better. Don't you agree?

- Congratulations. - My gosh, thanks.

Man Su.

You've been to countless crime scenes. You're a true detective.

I know your hard work. I'm in your corner.

Thank you.

Congratulations, sir. I'll do my best.

Okay. Thank you.

Congratulations.

Okay. Have a nice day.

What about Hyun Jae?

He's working outside the office.

He doesn't care about our organization and works alone.

That hasn't changed over five years.

It's typical of him.

All right. It's cold. Let's go inside.

- Okay. - Yes, sir.

Let's go in.

(Ha Tae Sik's Murder Case)

4, 7, 8,

Come in.

Did you want to see me?

Must you...

go against my order?

I told you to report Ha Tae Sik and Hyun Jae's conversation.

I told you not to leave anything out.

Must I eavesdrop on Ha Tae Sik...

to find out what he leaked to Hyun Jae like a rat?

I'm sorry.

I put you through college when you had nothing.

I worked hard to get you a job as a cop.

But you don't know who to thank.

If it weren't for you,

I know that I would've been sent to juvie.

I could never dream of being a cop.

So you know.

I'm always grateful.

If you know that, is this your way of thanking me?

Hey, you jerk.

Don't you know whom you should follow?

The people I hate the most...

are those who confuse me by changing their sides.

You know, I can't tell if they are my friends or foes.

I'm sorry.

You've gotten close to the people in your team.

And you must be loyal to Ha Young.

Why do you think I planted you in the RIU?

I made an investment...

for our organization.

I invested my time and effort in you.

Don't make me regret that I invested in you.

Do you want to go back to the streets?

I'm sorry.

Look into everything.

And find me everything that there is...

about 4, 7, 8, 9.

- My gosh. - Darn it.

What's that?

These are cold cases.

Senior Chief Choi transferred them to us.

What?

He's practically giving us the finger.

There are so many.

I should take it then.

Hey, come over here and take his finger.

- What are those? - These are unsolved cases.

Our team was assigned for this.

Who assigned them to us?

Senior Chief Choi.

He could've assigned them to other teams like Cold Case Team,

Youth and Women's Department, and Crime Division.

But we got them.

It's not a promotion, but a chain.

(2nd Senior Chief Choi Hyung Pil)

Titles aren't important these days.

Come in. Thank you.

Why are you directing all the cases from our station...

to my team all of a sudden?

You're the ace of Regional Investigation Unit One.

You must show me what you can do to keep your position.

I assigned you old cold cases.

Show me your capabilities within a week.

Investigation requires time, effort, and legwork.

How fast do you want me to be?

I'm planning to restructure our organization.

Teams with poor performances...

will be restructured from team leaders to rookies.

This isn't a threat. And I'm not trying to discipline you.

I'm telling you I will do what must be done at our organization.

I understand.

I'm sorry. I messed up the drawing on top.

Should I make another one?

No, it's fine. Just give it to me.

I'm sorry.

Is anyone out there?

Please help. Help me!

Help me.

Help!

I'm all right. It's just a dream.

You're all right. You're fine, Yoon Jung.

(Mucheon Metropolitan Police)

You're still here.

I'll go home after I drop this off.

I see.

Su Young.

Yes, sir.

I heard that you contributed a lot in solving Ha Tae Sik's case.

I heard you're very observant.

No.

I still have a lot to learn. My team is helping me a lot.

Do you mean to say that Hyun Jae is helping you?

I'm learning a lot from Detective Oh.

You're learning a lot from Hyun Jae.

He couldn't care less about our organization.

He does whatever he wants.

If you want to survive here,

you need a good superior.

Detective Oh...

is a good superior to me.

Are you sure?

Yes.

Good luck.

Hello.

Thank you.

What do you mean Hyun Jae went off the grid?

What does 4, 7, 8, 9 mean?

4, 7, 8, 9. I don't care if you make it up. Find that out.

We must catch the culprit, so it doesn't become a cold case.

- It's a serial murder. - There's a survivor.

She seemed to be traumatized.

Is it okay to ask her?

A year ago, I heard that sound.

Why are you working so hard on this case?

I was reminded of a saying.

That it could be someone's family.

Why are we always a step late?

We always end up seeing the victim's dead body.
