What?

What is this?

[Caller ID Restricted]

[Caller ID Restricted]

Hello?

[Stay in the car and listen.]

Who is this?

[I know who killed Park Jae-min.]

Oh, I see.

[If you want to know who it is,]

[just do as you're told.]

Are you sure you're not the culprit?

How will you prove that this isn't a joke?

[If I had the time to prove that, I would've rather cut your tongue out.]

[If you want to know who the culprit is, take down that stupid live stream video,]

[and admit on TV that you were wrong.]

[Then I'll call you back.]

Hello... Hello?

Hello?

[Caller ID Restricted]

What is this?

Is this for real?

What is this?

"In case of a fire, break this wall down."

What is this?

Oh, right.

They install fake walls so people can escape

to their neighbor's house in case of a fire.

I can't believe this is how the culprit came in.

Check the security footage and see who visited the adjoining unit

before and after the incident.

This unit was used as the model home,

so I bet a lot of people came here.

Okay.

[Tak Won's Detective Agency]

[Hundred Year Good Life]

I look good.

Look at my jawline.

[TEAM BULLDOG: OFF-DUTY INVESTIGATION]

[TEAM BULLDOG: OFF-DUTY INVESTIGATION]

"Tak Won's Detective Agency".

"Way better than an inquiry agency".

[We work like dogs.]

"We work like dogs"?

-Woof, woof? -What are you talking about?

My gosh.

[We work like lightning.]

[We work like dogs.]

My gosh, they used the wrong word.

Based on the looks of your partners, I bet people will pay you for murder

instead of investigations.

[We work like lightning.]

So you're telling me that someone

-left this cell phone in your car? -Yes.

Did you check who it's registered to and your dashcam footage?

I looked into it, but of course, the phone was a burner.

And I sold my dashcam a long time ago.

I was short on money for food.

Oh, dear. Your poverty makes me tear up.

Would you be interested in joining the business?

No, thank you.

Instead, please help me with the heart of Einstein.

You probably mean Schweitzer.

I think we're looking at the tenth Locked-room Murder Case

that occurred in 2012.

It's the same person, and so is the knot.

Wait.

Then, are you saying I actually talked to the Locked-room Killer on the phone?

Yes, most likely.

What did he say again?

He told me he knows who killed Park Jae-min

and that I should do as I'm told if I want to know who it is.

That's how you make a deal. Take and give.

Isn't it the other way around? Give and take.

No, it's better to get what you want first.

So what did he want from you?

He wanted us to delete the live video that Director Hong recently uploaded.

The show with Professor Pi? The guy who's uglier than me?

Yes, Detective Durian.

And he also wanted us to upload a video admitting that we were wrong.

Something must've scarred his pride.

Serial killers tend to get very angry

when people don't acknowledge their crimes

or are mistaken about them.

Then what should we do?

I can try what I can to delete the uploaded video.

But it's up to my company to decide whether to apologize or not,

so it's not something I can decide on my own.

You always have two choices.

You can either give him what he wants

and become a distinguished director who airs an interview with a serial killer

for the first time in history.

Or you can just ignore him and be a dime a dozen, just like now.

But what if this is just someone pulling a prank on me?

Don't worry.

We always have Hundred Year Good Life.

-I'll help you. -Shut your mouth.

I won't work there even if I lose my job.

[Lightning]

Why did the adjoining unit have to be a model home?

There will be tons of fingerprints and DNA there.

That's probably why.

My goodness, what's going on?

Why do you all look so down?

Hand them out to everyone.

Take one each and energize yourselves.

-Thank you. -Thank you.

Hey Dae-jin, did you find anything on the security cameras?

I did. Look at this.

Doesn't he look like the culprit?

That means he went inside pretending to take a look around,

used the fake wall in the balcony

to break into Park Jae-min's house, committed murder,

and waited until everyone else left until he could leave as well.

That gives me the chills.

That suitcase is probably for the tools he used for the crime

since he didn't take the body.

Then we'll get all sorts of evidence once we find that suitcase.

He's wearing a hat and a mask. It's impossible to tell who he is.

Now that we have the security footage,

investigate all the people who came to the model house.

Check all their alibis.

-Yes, sir. -Yes, sir.

Do you seem something? It's the same footage.

I just know. I can see right through him.

Really?

Who is he?

-Hey, Dae-jin. -Yes?

It's been a while since I did this, but let's use one of my tools.

What? It's a search warrant.

It's been ten years, but I still can't get a search warrant when I need one.

I'm letting you inside because you brought a search warrant.

But what's going on?

The old man and his wife would never do anything to break the law.

Well, it won't take long, so don't worry.

Thank you.

Why is she so suspicious?

Hey, search carefully.

-Okay. -Good.

Let's see.

Hey, long time no see.

-Have you been well? -Go.

-Get out of here right now. -Why?

-Get out. -Do you need to pee again?

-What's wrong? -Get out. Get out of here.

-What's with you? Let me go. -Get out.

Can we please just talk?

He won't budge.

He's so heavy.

I said let's talk.

I'm looking for a suitcase.

And I feel like it might be here.

I found it.

He found it.

It's exactly the same as the one we saw in the footage.

Gosh, there's no way to deny this.

Let's take him down to the station and interrogate him.

No, we need conclusive evidence.

It'll be a lot harder to catch him again if we lose him

-for not having enough evidence. -Oh, right.

I can't make the same mistake I made ten years ago.

Ask the NFS to examine this as fast as possible.

-Got it. -My gosh.

It's been a while.

I was expecting you after getting a call from Deok-su.

He told me that you took a suitcase from the house.

Will you arrest me again?

Well, I'm not sure.

I'm busy these days.

Oh, right.

How long will it take for you to shine them?

They are dress shoes.

Yes. That's my favorite pair of dress shoes.

My mother bought them for my birthday.

There's this guy I'm dying to catch.

After catching that guy, I'll wear these fancy shoes.

So do your best to shine them.

I'll be back to collect them soon.

So because of this video which you're not even sure is real,

you want to take down Director Hong's video and apologize?

When the video reached one million views now?

Chief.

I am certain that this video is real.

I confirmed it with an expert.

No expert can be as good as Professor Pi in this field.

There is one. He's called Detective Durian.

Who's that?

Anyway, help me out.

Can't you feel that this will be a huge scoop?

Broadcasting is all about credibility.

I must gain something from going with this risky move.

If we correct ourselves, it means we're flat-out wrong.

You will get something out of this.

If we do what he says, he says he'll call me back.

Who told you that? This serial killer did?

What if he doesn't?

My gosh, why are you so pessimistic? We ought to trust each other.

You want me to trust a serial killer?

So hear me out. This serial killer

might tend to keep his promises.

What if I get fired from this?

This doesn't just concern "Fact Check".

Without a sure plan,

I will not allow it.

What do you all think?

An interview with a serial killer who hasn't been caught yet.

This isn't just unprecedented in Korea.

It's unprecedented in the entire world.

But don't you think this is too dangerous?

There's the issue of broadcasting ethics.

And the Bureau Chief is against this. If this goes south,

you'll take all the blame.

But we can't just sit here and wait.

Our show has to air soon.

It is true that we're not as prepared as Director Hong's team.

But you know, let's say that we do upload an apology video.

But that Locked-room Killer might not even do what he promised.

He would have gotten everything he wanted. Do you think he'd call back?

We can make him call back.

How?

We can provoke him.

He told us to take down the video and upload a video to correct ourselves.

But he didn't tell us anything more specific.

[Hello.]

[I'm Director Kang Moo-young of "Fact Check".]

[First, I'd like to apologize.]

In our previous video, we claimed that

the Locked-room Killer could have killed Park Jae-min.

But it may have been rash on our part. So we'd like to correct that.

[So far, the Locked-room Killer]

[has only chosen weak senior citizens who would be easy to subdue]

[for his crimes.]

[Given the crime pattern of the killer,]

[the culprit is likely to have a small build]

[and suffer from an antisocial personality disorder.]

As a result, concluding that the Locked-room Killer

murdered Park Jae-min, a healthy man in his 20s,

would be somewhat of a stretch.

Director Kang will ruffle his feathers for sure.

She is provoking him indeed.

She's basically saying that he wasn't strong enough to kill Park Jae-min.

At this rate,

the Locked-room Killer might even sue her.

Right.

[It seems to me that he's a very petty man who wants to]

[parade his masculinity by murdering them.]

What?

I'm sorry. My apologies.

Darn it.

I don't think he's going to call us.

Our live stream ended a while ago.

I don't think our approach didn't work, right?

[Bureau Chief]

Isn't that the Bureau Chief? What are you going to do now?

I have no choice.

Let's go with Plan B.

-Do we have a Plan B? -No.

I'm trying to come up with one now.

What?

Since he's not calling you, you'll catch him yourself?

You are gutsy as ever.

If I don't get an interview with the Locked-room Killer,

I'll be fired.

And you egged me on too.

You should help.

Okay.

How come you agreed right away?

As long as you pay me decently.

You're asking the woman who had to sell her dashcam because she couldn't buy food?

You're cruel.

For your information, Detective Jin paid me 1,000 dollars last time.

Given your situation, let's just settle on 300 dollars.

Make it 50 dollars. That includes transportation and food.

Director Kang, don't forget who I am.

I'm the best profiler in Korea.

-I'll pay you 30 dollars. -Hey.

Director Kang.

Are you serious? 30 dollars is too low.

Then, 50 dollars.

You should pay me at least 50 dollars. Gosh, you're unbelievable.

End of negotiation.

Wait.

Shall we get to work now?

Dr. Lee.

You scared me.

I was testing out the new products.

Even if they are dead, I can't just use any products, you know.

What do you think?

Do I look lively?

Yes. Sure.

You look so lively that it scares me.

You little...

What brings you here at this hour?

Dr. Lee,

when you were working at the NFS,

were you in charge of the Locked-room Serial Murder Case?

I was on every case before I retired.

Why do you ask?

I'm investigating that case.

I need your help.

A favor for you?

I'll do anything.

You saved my daughter. You just name it.

My goodness, this is crazy.

Your attitude is superb, Dr. Lee.

I heard from Mr. Tak.

Given the cause, we're happy to help you.

Gosh, I knew I could count on you.

Red-Zone and I are partners.

So you can negotiate their fees with me.

Who said you could do that?

I know how much I'm worth.

You know, I'm short on cash.

Can I do an installment payment?

Then,

just pay me 20 dollars.

Well, then,

I'll only charge you 15 dollars.

My gosh.

You don't need to pay me.

We're a team.

Now, look here.

You are valuable assets. You shouldn't work for chicken feed.

You ought to properly negotiate like me.

You should at least get paid 50 dollars. Don't you think so?

Our boss pays us 5,000 dollars each month.

So I don't need a lot of money.

That's right.

Well, the land I bought a while back got redeveloped.

I'm not as well-off as Detective Jin, but I have a comfortable life.

Don't you need a part-timer by any chance?

[Geumpyeong Police Station]

How is this possible?

They couldn't find any trace of Park Jae-min's DNA in the suitcase.

If the murder weapon was in the suitcase, they must've found his DNA.

What did they find?

The old man and his wife's fingerprints

and some hair.

[DNA Assessment Report]

[The DNA is 99 percent not a match.]

I knew it.

No wonder it was found too easily.

What do we do then?

We should start over.

There was one survivor

of the Boxcutter Serial Murder Case.

"Son Ji-young". It's her, right?

I met her back then, but...

I saw nothing.

I was too scared.

She couldn't remember anything due to shock.

Then she disappeared.

I couldn't find any traces of her.

She moved out earlier today.

She left as if someone was out to get her. She was in a hurry to leave.

She must've gone off the grid out of fear.

That's why I'm thinking of meeting her family.

You should get the call history of Son Ji-young's acquaintances.

-See if anyone talked to her. -Okay.

-I heard you were looking for me. -Yes.

I'm Detective Jin Gang-ho from Geumpyeong Police Station.

You're Ms. Son Ji-young's father, right?

I haven't seen her since my divorce a few years back.

I'm aware of that.

I came to see if you could help me get in touch with her.

I had no way of finding either Ms. Son or her mother.

I don't know either.

I've never had contact with them since the divorce.

So please don't come looking for me anymore.

There must be a reason when someone disappears.

[Nothing stood out from the call histories of Son Ji-young's acquaintances.]

[There was a number her father, Son Un-sik periodically called.]

[But we can't get the caller ID because it's a burner phone.]

[That number was recently used to request an internet installation.]

[I'll send you the number and address.]

[143 Giyeon-ro 26-gil, Yangmi APT 2nd Floor, Jangyeon-gu, Seoul]

Hello?

Anyone home?

Who is it?

Here.

Do you remember me?

We met ten years ago at Ms. Son Ji-young's hospital room.

Sorry, ma'am. Just a moment.

Could you please spare me some time?

Why did you find us again? Why?

Don't you understand why we're living in hiding?

I'm sorry. Another case occurred after ten years.

Ms. Son Ji-young's testimony is crucial for catching the guy.

If that was the case,

it's even worse that you came here.

This happened because you came to see her back then.

Please leave.

Don't come back.

Wait. What do you mean that this happened?

Somebody came to the hospital back then, didn't they?

What difference

does it make?

You don't know what we've been through.

Do you have any idea how my daughter is?

Ji-young.

The detective you met before is here.

He'd like to talk to you.

Ji-young, I'm coming in.

Okay.

Ms. Son Ji-young?

Do you recognize me?

We met briefly ten years ago.

I'd like to ask you a few questions.

It'll only be a minute.

Why did you suddenly disappear back then?

Did someone come to your hospital room?

Was it

this man?

Get out.

Get out!

Mom!

Ji-young, it's all right. Ji-young.

Mom!

-Mom. -It's okay.

Ji-young.

-It's okay. -No!

Okay.

Mom?

[I told you that you're dead even if you're alive.]

[I'll kill you for sure if I see you again.]

What's wrong? What is it?

-Mom. -What?

He was here.

I'm telling you he's here!

Ji-young, come to your senses.

Mom, let's run away. We should run.

You've seen her yourself. Please don't come back.

I'm getting tired of moving.

I'm sorry.

This is the list of organizations that support and protect

the victims of crimes.

They'll be able to help you if you call.

And this isn't much,

but please use it for your daughter's treatment and other expenses.

I'll catch that guy no matter what.

The report is lengthy,

but it basically says you still don't have any suspects.

We haven't had any solid leads or witnesses yet.

Are you just carefree

or incompetent?

It's been two days since I held the press conference.

I guess you don't care about the public who are in fear.

Next time, don't bother to bring me another report about the process.

Bring me results instead.

Arrest the culprit by any means.

He held the press conference on his own, so why is he taking it out on us?

The public who are in fear? He's only worried about his promotion.

He always disappears when I need him.

Where did this idiot go?

There he is. The idiot.

Who's the idiot?

Just some guy.

-You don't need to know. -I think you're referring to me.

Oh, right. Did you find her?

Was it Son Ji-young's number?

I found her, but we can't expect too much from her.

We keep going in circles.

We're back to square one again.

Wait a minute. Son Ji-young?

Are you still thinking it was the Boxcutter Killer

who killed Park Jae-min?

You know there's some connection.

It's not like we have a suspect.

Fine. Go ahead. Do whatever you want.

No one can stop you.

Let's just hope you get lucky.

But don't be rash like you were ten years ago.

Goodness. I guess people really do

lose their vigor and give up more easily with age.

You little punk.

Okay, great.

Then let's go ahead and start doing things my way.

Here.

Are these all material on the Boxcutter Serial Murder Case?

I want you to meticulously read through everything again.

I'm sure we missed something.

You want me to do this by myself?

Of course.

You were tenacious enough to call your ex-girlfriend 100 times.

Use your obsession, stubbornness, and tenacity

to dig into all the documents.

You may have failed to get your ex-girlfriend back,

but you can use this chance to catch the serial killer.

Your ex-girlfriend may have hated all those things about you,

but use them to your advantage and turn them into your strength.

-Okay? -Gosh, will you stop?

I admire your amazing tenacity.

Well then, good luck. I have a lot of work to do.

Unbelievable.

My goodness.

My gosh, seriously.

Hello, everyone.

Why are you so late? We were all set ages ago.

I had to visit the NFS.

But you act like you're the host.

Why do we always gather here?

Detective Tak's office is depressing,

and Mr. Jeong's bar has to open for business.

Besides, this place is spacious and nice. The AC is always on.

Why do you need the AC when it isn't even summer?

-Did you turn it on? -I'm just saying I feel comfortable here.

Shall we begin?

My goodness.

But what about Detective Jin? Aren't we here to catch a culprit?

That lousy cop will take the culprit away the moment we catch him.

We can't have that. I'll do the interview first,

and then hand him over.

We might not need handcuffs, but what about the money?

It might cost us a lot of money to carry out the investigation.

You guys must've gotten addicted to the money you got last time.

Let's leave him out this time.

We'll discuss Detective Jin later.

-Sure. -Okay.

Okay then.

-I'll begin. -Okay.

First, can you explain what the Locked-room Serial Murder Case is?

A total of 15 people

were murdered by the Locked-room Killer since 2005.

And most of the victims were old people who lived alone.

[Here is why it's called the Locked-room Serial Murder Case.]

The victims were all murdered in their homes,

but there were no signs of anyone having visited them.

The killer also used tools from within their homes to kill them.

The one thing these cases had in common

is the knot that the culprit used to tie them up.

[It's very easy to tie and untie this knot.]

Knots like this are made subconsciously because people are used to it.

That's correct. It probably came out habitually

due to his job or hobby.

Then let's hear what you found during the autopsies.

The victims died due to excessive bleeding that was caused by different wounds.

But what's weird is that there weren't any defensive wounds on their bodies.

We detected an anesthetic drug in their bloodstreams,

but there were no needle marks on the victims' bodies.

He would've put it in food or drinks. It's a typical method.

The culprit knew all the senior citizens who lived alone.

So he's probably a social worker

or an employee at a community service center.

No, that's probably wrong.

I disassembled the cell phone that Director Kang found in her car.

And I found something on the screws.

[I was able to detect nitrogen oxide and phosphate.]

Nitrogen oxide is commonly found on construction sites,

and phosphate is normally used to process food

or make fertilizers.

Therefore, the culprit probably works

at a food processing company or a fertilizer plant.

There are tons of businesses like that in Seoul and Gyeonggi Province.

Gosh, it's like finding a needle in a haystack.

Someone sent me a photo regarding the knot.

-Let me see. -Here.

It's the same knot, right?

This is scrap paper.

Where is this place?

I didn't get the location. The person just sent me this photo.

Don't worry. We can always narrow it down.

When serial killers succeed

in killing people without getting caught, they become confident...

and start committing crimes closer to where they live.

It's a typical characteristic of serial killers.

Here. Let's take a look at the Locked-room Killer.

He started killing people in the western area of Seoul.

But more recent incidents occurred in Dongpyeong-gu of Seoul.

So it's highly possible that he lives in Dongpyeong-gu.

Dongpyeong-gu?

Wait a minute. Dongpyeong-gu...

Dongpyeong-gu...

Dongpyeong-gu...

Wait.

There's a food processing plant in Dongpyeong-gu.

Then is it time to catch that jerk?

Don't jump to conclusions, Teddy.

The guy who left the cell phone in her car

might not be the Locked-room Killer.

He could've been a messenger.

But still, we should go and take a look.

And take a close look at the scrap paper.

Okay, let's go.

-Okay. -Nice.

How can I help you?

Hello. We called earlier.

I'm Director Kang Moo-young for OCM's "Fact Check".

-Come this way. -Okay.

[February Work Schedule]

I see you all worked late three days ago.

Did anyone go home early that day?

No.

It was the day before we had to make a delivery.

But what kind of case are you investigating?

Oh, he must be a detective.

-Well, I'm... -Yes.

This is Jeong Man-bok, a section chief at Geumpyeong Police Station.

We're gathering information regarding a stolen car.

My goodness, none of our employees would steal a car.

But of course, I'm sure you'll catch the culprit.

I'll catch that punk and bury him alive.

What?

It means he's going to catch him no matter what.

Of course, he should catch him.

[Close down the factory that emits carcinogens!]

Are you okay?

I'm okay.

But I have to say, I feel bad for the residents here.

[Close down the factory that emits carcinogens!]

I guess the dust from the factory spreads throughout the village.

Wait a minute.

Then it doesn't need to be someone who works at the factory.

The nitrogen oxide and phosphate could've come from someone

who lives in this neighborhood.

Yes, that's possible.

Sir! Wait!

You dropped this.

My goodness. Thank you. Thank you so much.

Look.

What?

Sir, did you tie this knot yourself?

No, I brought it from the market over there.

"The market"?

Wait.

Hello, ma'am.

Can I ask you something?

Did you tie this knot yourself?

This?

No, Mr. Do did it for me.

"Mr. Do"?

I'm not talking about a thief or anything.

There's a kind man who fixes the radiator for free

every year when winter comes around.

His name is Do Gi-tae.

Someone who fixes the radiator for free?

-Hello. -Hi.

There must be a lot of radiators to fix since it's gotten cold all of a sudden.

I still need to find time to help the elderly.

I'm always so grateful to you, sir.

That volunteer who came to the event?

Hey, Mr. Lee. About the stuff you found on the cell phone...

Could it also be found on someone who fixes radiators?

[Yes, it's possible.]

[They're easily exposed to nitrogen oxide,]

[and phosphate is used to clean the radiator pipes.]

I think we found a key suspect.

It's a radiator mechanic who does volunteer work at the community center.

I'll send you an address.

Go there with Detective Tak to collect evidence.

We'll go straight to where he was working. Okay, bye.

-Let's go. -Okay.

[Boxcutter Serial Murder 11th Case]

Wait. I found something.

Someone witnessed the body being abandoned.

The 20th case?

The body was found in the drain right next to Yangsu Street.

What? How do you know that?

Because I read it hundreds of times.

It's all saved in my head.

Then why did you tell me to read everything again?

Just in case I missed something.

Let me take a look.

[Boxcutter Serial Murder 20th Case]

Where is it?

[List of evidence]

[Dashcam footage]

[USB, Geumpyeong Police Station]

211...

211...

Okay.

The video quality is so bad.

Well, the dashcam footage is more than ten years old.

Until recently, it was difficult to restore videos

with such low resolution.

But technology has developed since, so it became possible.

We can capture the images after dividing them into 60 frames per second

and enhance each image to put them back together.

How long would it take?

I'm not sure. I'd know once it's done.

It looks like we might be able to get a face.

I'm glad we've been saving the evidence.

We might really get a face.

This is clearly illegal trespassing.

We'd get arrested right away if the police come.

Should we just go back?

Normally I would,

but I owe Director Kang.

And you've been paid too.

I'm too underpaid to commit breaking and entering.

There's a fence and the door is locked too.

You said there was no one inside.

We should just climb over.

-What are you doing? -Me?

It hurts.

Gosh. Get out of there.

Take this.

-It hurts. -I know.

You're surprised, aren't you?

I might look intellectual and elegant,

but I was in the Special Forces.

You don't look intellectual nor elegant,

but I'm still surprised to hear that.

Check this out.

Do you want me to climb again?

You should be the one to open the door of crime.

I'm former police, you know.

-I was a coroner. -Who were in the Special Forces.

Goodness.

Good job.

[Sentenced to 25 years in prison]

[Sentenced to 5 years in prison]

[1st, December 24, 2005 2nd, November 14, 2006]

["Korean Forensic Science, Profiler Tak Won"]

Look at this. "Profiler Tak Won".

He chose the right learning material.

He even worked out to commit a perfect crime.

Is this enough for a workout?

Let's see.

Let's see.

Ban-seok. Hey.

What?

-He went home? -Yes, he did.

He fixed the radiator and went home already.

You don't look like burglars.

We are vloggers who normally visit deserted houses.

I guess it wasn't a deserted house since the owner is here.

Excuse us.

You thought my perfectly fine house was deserted?

Yes, well... We must've been mistaken.

Let's go.

You've seen too much for me to let you go.

You are one guy who is up against the two of us.

-What about that? -I'm saying if things get physical,

you'd be at a disadvantage.

Yes, I ask you to make a wise choice.

Forget it. You can both come at me at once.

At once?

I refuse such an unfair fight since I used to be in the Special Forces.

I'll go first.

Will you take off your jacket?

Let me.

Stay back.

Take this.

Ban-seok!

-Blood... -Blood?

A nosebleed wasn't part of my scenario.

Next. You.

Get revenge.

It hurts.

I think you're underestimating me.

You've made a precise judgment.

Two to zero.

Then, I should...

["Profiler Tak Won"]

It's you.

The profiler who was adopted to the US and returned home in glory.

That's an overstatement.

I'm working as a pyramid salesman right now.

You said it wasn't.

Network marketing is the pyramid.

But you've found me anyway.

Your skills should be recognized.

I'll take that as a compliment.

We're about to die. What good would a compliment do?

It's better to get a compliment if you're going to die anyway.

Of course.

But sir, if you do this in your house,

your record of locked-room serial murders will be damaged.

The reputation you've built is important.

That's just some gibberish you elites made up.

-I don't care. -He doesn't care.

-We should just quietly die for him. -Come on.

It'll be hard to get rid of two bodies.

That's my business. You should mind your own.

Gosh.

I always had to kill old people

who had wrinkles and tough skins.

I'm so excited by your soft and tight skin.

Excuse me, sir.

If you suddenly change your MO, you'd definitely make mistakes.

Plus, we're so different from your regular targets.

You talk too much.

-Is this where you were? -Are you hurt?

-The Locked-room Killer. -Here.

-The Locked-room Killer! -The Locked-room Serial Killer!

Was that you?

-Locked-room! -Serial...

The serial...

-You got him! -Hey.

Darn it.

How about we have a go?

Teddy!

-Teddy! -Teddy!

You people keep coming in.

-Hey, are you their leader? -Teddy!

I'm not their leader, per se.

I'm their boss.

-That's it! -Yes, that's it. Teddy!

My gosh, this guy is pretty strong.

Are you okay?

Blood. Hey, he's...

-Are you okay? -I'm fine.

Here.

Gosh. Teddy, help me with this.

-Tools, are you alive yet? -Director Kang!

You bet I am.

-Director Kang. -Right here.

Oh, no. Are you all right?

How badly did you get beaten up?

One punch.

-One punch? -Yes.

Is that important right now?

-Right. Wait. -Untie me now.

-Hurry. -I'm all right.

Even in this dangerous situation,

I was stalling time by calmly persuading the serial murderer.

You saved yourself with just a few words.

-You're the best, Mr. Tak. -Thank you, Teddy.

Be quiet. Just change your underwear.

Don't be absurd.

My underwear is very nice and dry.

If you don't believe me, I can...

-What? Why didn't you untie me? -What?

The knot.

I can't destroy such a crucial piece of evidence.

-Right. -Hey.

But you untied him. Why did it have to be me?

Well, Dr. Lee was hurt.

I need to go to the hospital.

He doesn't look that different from his usual self.

You should be careful with your words.

What?

You must remember that you cannot defend yourself now.

-You little-- -Hey, let's move him first.

-Untie me. -Stand up.

-Stand up as you are. -All right.

-In 1, 2. -I got a cramp.

You and I should have a go at it.

This isn't the police station. Who are you guys?

Strangely, it's annoying to see a serial murderer get all worked up.

It was you who broke your promise.

How dare you lie to me?

You were the one who provoked me.

What? The fact that I called you small in stature and antisocial?

-I was right. -You jerk!

All the victims you killed

were weak and feeble senior citizens!

Well, it was because they were useless in our society like scrap paper.

-They're insects that eat away my taxes. -You...

-I see. -A serial murderer is worried about taxes.

Gosh, that feels so creepy.

Don't you agree?

Hey, you scumbag.

Do you think you'll never get old?

Who are you to judge their lives?

Since you can't rationally argue with me, you'll resort to violence?

Getting criticized for using violence from a serial murderer

who killed 15 people

is infuriating me.

-Fine, I'll use violence. -Wait.

Wait.

Anyway, is what you said before true?

Do you really know who killed Park Jae-min?

I'm not sure.

Serial killers tend to say

that they killed more than others like it's a competition.

How interesting.

You're proactively telling us that you didn't kill him.

But at least,

I didn't have an accomplice. That'd be embarrassing.

What do you mean?

What do you mean you didn't have an accomplice?

I don't want to eat jjamppong.

Gosh, I guess he doesn't like jjamppong.

-Right. -My gosh.

-I got it. -What?

-It's 14J 9113. -14...

And right here.

What?

This is

Ham Deok-su.

[14J 9113]

Are you telling me

two people killed Park Jae-min together?

So there was an accomplice?

Yes, Detective Choi.

What?

Excuse me.

-What's going on? -Step back.

Hey, move.

Darn it.

Is she...

Yes. That's Son Ji-young.

The only survivor of

the Boxcutter Serial Murder Case.

He killed her ten years later after letting her go in the first place?

And right in front of our station?

She wasn't murdered here.

Son Ji-young lived in Jangyeon-gu.

He abandoned the body here on purpose.

On purpose?

-Exactly. Why? -Because I'm investigating the case.

This is probably a warning message to me.

-She must be the mother. -Stop, ma'am.

What is this about?

-Oh, no. -This is awful.

Let go of me.

My daughter.

Ma'am, please calm down.

My daughter!

No.

-Calm-- -No!

No. Wake up, Ji-young.

Ji-young, wake up.

No! Wake up!

No, wake up. Ji-young!

[Do Not Enter, Police Line]

[TEAM BULLDOG: OFF-DUTY INVESTIGATION]

[I'm trying to uncover the truth. How is that wrong?]

That's your opinion.

[Gang-ho, stop it. The case was closed.]

[The real culprit is still at large. What are you talking about?]

[Isn't this suppression of the press?]

[Yes, it's exactly that.]

Are you telling me that my show might get canceled?

[I'll prove them I'm right and countersue them.]

[This isn't a team. I'm your boss.]

And you guys are my subordinates. Understood?

[The organization made a decision. Our duty is to follow it.]

[Not mine.]

[I'm more interested in public safety than some darned duty of a cop.]
