Dispatch for Taewon 32 Fire Crew.

A fire at a container diner in 38 Mountain, Dongju-dong.

Dispatch for fire, rescue, and medical teams!

Dongwoo.

- Let's get it done quickly! - Yes!

TAEWON FIRE HOUSE

There seems to be a lot of smoke.

Oh, dear. That will at least take two hours.

It might be tough.

FIRE AT AN ABANDONED CONTAINER DINER

CODE RED: EMERGENCY CODE INDICATING FIRE

This way! Come this way!

Darn it.

Hurry up.

SEOUL FIREFIGHTERS

-Let me go check. -Fire's spreading,

and the back routes are all blocked

-for us to enter. -Fire crew, arrived.

-Kisoo. -Yes?

-Radio the current situation. -Yes, sir.

- Baek Inju! - Yes?

- Take out a water hose. - Yes, sir!

Water hose, coming.

Kisoo, assist me.

Taewon Pump, turn on the water!

Spraying!

CONSTRUCTION DINER

The flames are too strong.

Dojin, should I spray water from the side?

Yes, I'll get the fire spot in the center.

Go and cool down the gas.

Yes, sir.

- Inju! Assist him. - Yes?

- Pump the water! - Pumping!

Mr. Baek!

There's 40-ton toluene tank next to the paint factory.

If it blows up, the whole area will be damaged.

What, toluene?

There are 40-ton of toluene.

Considering the current wind speed,

its toxic gas could spread tens of kilometers away.

If it leads to a mountain fire, the nearby apartments will be in danger.

A toluene tank at the one o'clock direction!

Stop the fire from spreading!

- Run! - Yes, ma'am!

Myeongpil, come here.

Yes!

The flames are getting stronger!

When did you get here?

I heard something earlier.

Is anyone inside?

Then they would've come outside to evade the fire.

Someone's inside! Call the medical team now.

-Paramedics! Here! -Hurry!

- Dongwoo, let's go. - Okay.

- Stand by here. - Okay.

If there's smoke, people usually hide in a corner.

Check the corners.

I found him!

- Let's lift him. One, two, three. - Two, three.

Let's move him.

Gosh. He's darn heavy.

The container might blow up at this rate.

-Inju, get the fire spot. -Yes, sir.

Chief, the air's getting sucked in, and the fire's dark red.

The internal temperature must be about 600.

The container could blow up at this rate.

We must lower it.

Will you be able to go inside?

Only if we discharge the smoke.

Let's remove the roof and pour water to get the smoke out.

No, that's too dangerous.

No, we can do it.

Kisoo! We're going up the roof. Get ready!

- Yes, sir! - Inju, get ready!

Give me the power cutter!

Okay!

Here you go.

Give me the ax!

Yes, sir.

Give me the water hose!

- Turn on the water! - Turning on!

Dojin, come down! The roof might cave in!

Oxygen's dropping.

Dojin! It might cave in for real!

It can last a little longer!

Just untangle the water hose first!

- Kisoo, go down. - I won't go down alone!

It's dangerous, so go down already!

- Now! - Yes, sir.

Untangle it now!

Untangle the water hose!

It's entangled there!

Untangle the hose!

Water hose, untangled!

The fire's slowing down!

Go in once we've cooled down the gas!

- Get ready to enter! - Yes, sir!

The patient inhaled toxic gas.

We'll give him oxygen as we transfer him.

Taewon fire crew, report your status.

Bong Dojin, clear!

Choi Kisoo, clear!

Lee Jihoon, clear!

Baek Inju, clear!

Okay, let's get the embers now.

Stay away from the walls. They might cave in.

Yes, sir.

- Jihoon, come here when you're done. - Yes?

Yes, sir.

Stop! Stop spraying!

What is it?

-Jeez! -What?

I guess we were too late.

Call the police.

Yes, sir.

The body was found as the fire at the diner was put out.

The identity and age are unknown. We assume it's a male.

The posture is a little odd.

It's called a pugilistic posture.

It's because the heat denatured the protein in the body.

It may not be a proper comparison,

but when you grill pork belly, it shrinks round.

It's similar to that.

Gosh, today's lunch menu is stir-fried pork belly.

Will you focus?

Let's start with the neck.

Will you turn off the lights?

UV light.

It's fluorescent.

FLUORESCENT: MATERIAL WITH FLUORESCENCE

What's that?

It's the leftover of a burned string.

It got stuck on his skin due to the fire

and wasn't visible, because it was hidden in his neck wrinkle.

A foreign substance on a neck can be critical.

Because the neck is most directly related to life

after the heart.

Give me a scalpel.

Opening up chest and abdominal cavities.

Give me the rib shears.

RIB SHEARS: A MEDICAL TOOL TO CUT BONES

Opening up the bronchus.

The bronchus barely has any soot.

This is unexpected.

If one dies due to a fire, they breathe in smoke,

which makes their bronchi black.

But his bronchus is not.

It means he wasn't breathing during the fire.

Let's collect the heart blood.

The soot in your nose means you're alive.

And he was already dead when the fire broke out.

Tell them to identify him with his DNA.

It's the reconstruction data of his cervical vertebrae.

Do you see the broken hyoid bone here?

It means he was choked to death strongly enough

for his hyoid bone to break.

He died of asphyxiation

and neck compression by an unidentified string.

He was strangled to death.

In short, possible murder.

The body was burned too severely that nothing about the culprit was left.

The only thing that the autopsy can tell us is how it happened.

He was strangled first,

and the fire broke out afterward.

Could they have started a fire to get rid of evidence?

If an autopsy can tell a murderer's intention,

you won't be needed.

We have identified the victim. He's Bang Pilgu, aged 57.

But check this out.

DOBONG POLICE STATION: FINE 300 DOBONG POLICE STATION: SENTENCE 1 YEAR

He had 13 previous convictions.

And he'd recently gotten released.

This case has been changed to a murder case.

Let's go.

I asked you to come over to let you know of something in advance, prosecutor.

FIRE AT AN ABANDONED CONTAINER DINER, A DEAD BODY WAS FOUND

Seeing how you called me over alone,

I guess it's for something trivial

or something unusual.

Prosecutor Yeom Sanggu, a great man like you

shouldn't be cleaning up the mess of what is transferred to you.

It's about time you designed one yourself.

This right here will help you show your presence to the world.

Don't tell me you're still putting out the fire.

Can't you see? We're investigating the fire.

How naive of you.

This was murder by arson, right?

How did you know?

-Hey, did you tell him? -No.

There, there,

and there.

There are at least three ignition points.

Multiple ignition points are direct evidence of arson.

So, someone sprinkled a flammable here three times?

The pattern says it's liquid.

And it smells like lighter oil.

So you have a very sensitive nose.

But we do things scientifically.

Anna, did you find something?

Just a moment.

What caused the ignition is most likely...

OTHER SUBSTANCES: VOLATILE OIL

He's right. It's lighter oil.

Science is good, but experience shouldn't be neglected.

I did call his nose sensitive.

Hey. Don't treat me like I'm some mutt.

I know that you fire crew worked hard to put out the fire.

But look at the mess you created.

It's impossible to know how the scene was at first.

How come it's impossible?

That window broke before the fire.

And the door was closed throughout the fire.

In this case, the arsonist entered and ran off

through that window.

Your fiction's quite detailed.

You think this is fiction? Let me show you the evidence.

Follow me.

Only the inner side of this door is sooty.

It says the door was closed throughout the fire.

It's clean, right?

If the window broke during the fire, the floor should be sooty.

But it's not.

This means...

...the window broke before the fire took place.

These are facts based on science, not fiction.

It rained yesterday. Hey, check the window!

- Anna! - Yes?

They left footprints as they jumped down here.

Fortunately, the fire crew didn't spray water on this side.

I'll make mold right away.

MOLD: A WAY TO RESTORE A SHAPE BY SOLIDIFYING LIQUID

You're on Jindo Dog's radar now.

The fire crew did all the forensics today.

Thanks, Dojin.

After all, Bulldozer is better than Jindo Dog.

Hey, keep investigating.

Do we have more to find?

Everything got burned, so it wouldn't be easy to find evidence.

Right. We're lucky to have found the footprints.

Detective Jin, did you find something?

Only the surface got burned. What's underneath it didn't.

Like that glass piece.

That's called a protected area.

You didn't flip this, did you?

We didn't even touch that area.

I got you.

What did you get?

They're drip stains.

The victim was an adult male. He must've resisted.

It might leave a culprit's bloodstain in such a case.

Collect every drop of it.

Okay. I'll make an urgent request to the National Forensic Service.

Okay, we just need to identify the culprit now.

We have to find the murder weapon.

Search the area!

How can we be sure whom this bloodstain belongs to?

The DNA test will tell us.

This is not a simple fire case.

Search every corner of the area, please.

Let's begin!

-Yes, sir. -Yes, sir. Spread.

Spread out.

Ms. Yun.

These nine bloodstains from the scene,

it's a little odd.

ANALYSIS REPORT

RESULT: THE DNA IS A MATCH TO JIN HOGAE'S.

Will you double-check it?

Sure.

Hi, Seol. Can you check something for me?

What is it?

The list of those who called 119?

I'll ask the control room.

It's 140 by 70.

It's suspicious, but I don't think any fingerprints are left.

Code this as a priority.

The autopsy found a sting on the neck.

Okay.

Okay, thank you.

This is not it.

- We found something here! - Here.

What is it?

Okay.

I guess Jindo Dog won't bite me now.

Good job.

Did you get the list?

The control room said they'd send it to me soon.

How's that guy you transferred?

They say he'll be all right

after receiving hyperbaric oxygen therapy for a few days.

Detective Jin.

We found the tool.

I see. Anna!

Look at all these fingerprints.

It has tons of fingerprints here.

We're comparing the footprints to the database, so it'll be over soon.

Good. Everything's going smoothly today.

Right, you did well.

Let's take a selfie.

One, two...

I got the list.

The reports are listed by time.

Let me see.

A total of 32 people reported it.

The first report was made at 06:28:18.

This is the phone number.

Why are you checking the first report in particular?

The more secluded a place is,

the first reporter is the prime suspect when it comes to an arson case.

NATIONAL FORENSIC SERVICE

ANALYSIS REPORT

-Detective Jin. -Do we have the fingerprints?

Yes, but it's...

Why are you in a daze?

ANALYSIS RESULT NAME: JIN HOGAE

What? Hey. Can't you manage evidence pieces any better?

FIRE CAUTION: FLAMMABLES

Hey, isn't this from Woo Miyoung's place?

Yes, why is it here when it's supposed to be in the evidence storage?

Besides, we found only your fingerprints.

The footprints next to the window are from the police shoes.

Do you see the police logo here?

The model is K1-905.

One with a vapor-proof function.

Is your foot size 285 mm?

Yes.

Then all fingerprints and footprints belong to Detective Jin.

Are you accusing me of arson and murder now?

I mean...

We're from the Migeun-dong inspection team.

Is this Lieutenant Jin Hogae's desk?

What is this about?

Search his desk.

We've arrived.

Things must be getting heated up by now.

Everything's ready and set.

Go get the best of it.

All right.

- Jindo Dog. - What on earth?

You haven't changed.

The Regional Investigation Unit and the east district prosecution

will take over the Bang Pilgu case as of this moment.

Everyone, stop what you've been doing and withdraw.

What?

You can't take the case from us after all we went through here!

I'm sorry for the trouble,

but we already know the culprit.

Hey, why did you come with him?

It must've been hard without any cameras around.

But fortunately,

there was a van that sold adult goods at the interchange nearby.

Its dashcam captured a man

who came this way 30 minutes before the fire,

according to the tip-off.

I doubt you were trying to buy adult goods there.

Isn't it unfair to investigate the scene of the crime you committed?

Excuse me.

I'm Officer Bong Dojin, and my team was the first to arrive here.

As for an arson case, it is our protocol to investigate the first reporter.

I have the list, so why don't we check this first?

Hmm... The first reporter.

Let me try calling him right away.

Oh, dear.

You reported it first, too.

Hold on a second.

What's wrong with that? Should he have just passed by, then?

Detective Jin, why were you here?

RESTRICTED NUMBER

Just give him the alibi, and prove your innocence.

What is it?

Right.

Whatever situation you were in, you need to tell them.

You guys, just stay quiet.

What are you talking about?

Why can't you tell them? You must have an alibi.

There's direct evidence, and you have no alibi.

Let's go by the book.

Jin Hogae, you're under arrest on suspicion of murdering Bang Pilgu

and committing arson.

Are you with them, Youngsoo?

What are you saying?

Kim Hyunseo's case and this one.

Murdering two or more people is considered serial killing, you see.

Say that again, bastard.

This is it.

Your nasty temper makes you act before thinking ahead.

That's why your DNA was all over the body.

So you had to burn it all to ashes, right?

Hey. It's just circumstantial and indirect evidence.

Unfortunately, the scene was burned down,

thanks to you.

She's from the NFS, bastards.

Ms. Yun, is the DNA analysis result out?

Yes, just now.

Hey. Listen carefully on who the real culprit is.

The nine bloodstains all indicate the same person.

They weren't from the victim.

Who is the person?

He's right here.

Detective Jin Hogae.

What are you talking about?

We checked four times each.

The bloodstains were from Detective Jin.

This is a conclusive and irreversible fact.

Why would it be my blood when I'd never even come here?

The NFS never lies.

You must've tussled quite severely.

- Darn it. - Goodness.

Did they buy you off, too? Just how far up does this go?

Get him off. That's enough.

I said it wasn't me!

Thanks for finding the direct evidence, too.

You sure are a detective.

I couldn't handcuff you seven years ago,

because of the lack of direct evidence.

But it's different this time.

And aren't you shameless to be a detective...

after murdering someone?

Beware of this punk.

Once a dog has a taste of blood,

it can never forget about it.

Detective Jin, this is not true. Why can't you tell them?

Just what are you hiding?

Can't you trust me, either?

I'm your partner.

Get him out of here.

These are the bandages and medicine for him.

All I asked you was to watch

if the Jindo Dog was doing well.

But you let me get backstabbed by my subordinate.

The thing is, when...

I'll lose myself to see my son go to jail.

I won't be able to do anything

with a murdering criminal for a family.

Everyone has their own dirty laundry.

I despise those who break their promises.

I'll be seeing how you do with yours.

SEOUL METROPOLITAN POLICE REGIONAL INVESTIGATION UNIT

TITLE: REQUEST FOR ARREST WARRANT NAME: JIN HOGAE

Now that you're dealing directly with Ma Taehwa,

does it feel like you've jumped on a golden bandwagon?

You taught me that prosecutors must speak with evidence.

I only prosecute whomever evidence is indicating.

The fall of Lieutenant Jin Hogae.

Isn't this what you also wanted?

SEOUL METROPOLITAN POLICE REGIONAL INVESTIGATION UNIT

I got this from the inspection team.

You joined a life insurance plan under Bang Pilgu's name and paid for it.

The beneficiary was you.

If he died of an accident, you were to get 2.5 billion won.

But with a holiday option, it became 5 billion, twice the amount.

Are you out of your mind?

The amount is big enough to commit murder.

There was a similar insurance fraud case in Taewon, right?

Nice job applying it.

Article 231 of the Criminal Code, fabrication of private documents.

What are you talking about?

Documents never lie.

We even found evidence of illegal gambling from your computer.

Is that why you urgently needed money?

You designed it quite well.

Specifically, make Detective Moon Youngsoo

of the Regional Investigation Unit in charge of his case.

This guy will handcuff him for you.

I'll do the evidence-making. You just have to put it well together.

You'll make evidence?

Documents don't lie, you see.

It'll be taken straight to the ruling.

Shouldn't you graduate from being

Chief Prosecutor Jin Chuljoong's minion?

Our Hyunseo was so fond of Officer Jin!

The last person she called was also that Officer Jin!

Her toe was even found in the yard of his house.

So why wouldn't you arrest him?

- Why? - Sir.

FURTHER INVESTIGATION NEEDED DISMISSED

What is this?

It didn't even get to the court,

but the prosecution dismissed it?

Oh, goodness.

This might be enough to have someone killed unintentionally.

That was extremely thrilling.

It's not as satisfying as your rulings.

You're flattering me.

You always make

a flawless ruling based on evidence.

It's so admirable.

I'm just a criminal division judge.

I'm alone without any strings attached.

I hear you have a plan for politics later in the future.

Uh...

Dealing with criminal cases,

I've realized how the world works.

What if I become...

your string?

Your desk became a total mess.

Just what is going on?

Right before I came to Taewon, I was in charge of Ma Taehwa's case.

Hey, Ma Taehwa.

-Are you okay, sir? -Hey!

Come over here!

Don't fuss.

Get off me!

You may go wild as much as you want,

but I'll still be acquitted as long as there's no evidence.

He forged his innocence when he was obviously guilty.

Now, he's forging my charges to make me a murderer.

Just say that it wasn't you.

Or plead the Fifth if that's better.

You didn't even do it. I don't think...

It doesn't matter now who murdered Bang Pilgu.

It's about whether we can nullify the evidence against me.

Then you're at a disadvantage.

The judges will look only at the documents.

According to the report, you're the culprit for sure.

You could be sentenced to life at this rate.

No, you're charged with arson, too.

They might even demand the death penalty.

Anyway, keep it to yourself.

No one can be trusted now.

It's me.

Will you make time for me?

You'll meet some familiar faces at the detention center.

Take care.

This is called a guillotine cutter.

The name comes...

...from cutting a neck like an actual guillotine.

It works quite well.

I quit smoking.

Ahh...

I see.

This time...

you crossed the line a little too far.

Don't you know who crossed the line first?

Didn't I tell you

to hold the mad dog on a tight leash?

What are you waiting for?

See him off.

During the French Revolution,

those with wealth and power were guillotined more.

Don't think it's just an old story.

This is a warning.

He made it to chief prosecutor with spite alone.

You shouldn't think lightly...

Did you just smirk?

No, sir.

Do you look down on me?

-No, sir. -You saw him smirk, right?

I know you smirked. You jerk...

You know what?

When I set my mind on something, I get it done.

Sir!

Sir.

Did that scare you?

You got scared, didn't you?

Jin Chuljoong got scared and rushed over here.

This time,

I'll take this to the end.

All right?

Hey, Jindo Dog!

I'm going to kill you, Jindo Dog!

Woof, woof!

Hey!

Long time no see, Jindo Dog.

It's been a while, Choi Moogil.

You got here for theft again?

No, it was special violence this time.

Hey, Jindo Dog of Regional Investigation Unit is coming.

That bastard killed a person.

No wonder why his eyes seemed dark.

He arrested a lot of the inmates in this cell.

Clean up the room

before we welcome our guest.

LIEUTENANT JIN HOGAE

Let me help out. We should clean his desk.

No, thanks.

His stuff will be moved out, anyway.

What do you mean?

Jindo Dog, my foot. He's just a mad dog.

Myeongpil, you don't sound like yourself.

Come and eat, guys.

-Great! -Thank you for the food.

-Come in and enjoy. -Come.

This is crazy.

Seol, hurry here.

Dojin's ramyeon is the best, though.

Right.

By the way, did Detective Jindo Dog really commit murder?

Hey.

I just thought he was nuts at first.

Doesn't it give you the creeps?

It's not sure yet, Dongwoo.

Still, he was kind of violent, right?

I'll eat later.

Did you have to say that?

He was our colleague.

It's okay. Eat up.

We'll go investigate after you eat.

Okay.

Dojin.

There's not one CCTV installed here. Can you believe it?

What about the paint factory? They stacked lots of materials there.

Could there be a camera there?

Look.

All the cameras are facing away from the diner.

This one.

Get its footage from the day of the fire.

It wouldn't have even captured the scene, so why?

Let's just check anything first.

Darn.

I've been waiting for you.

Look at you. You've gotten so chubby.

Aah!

Oh!

I was feeling stiff, anyway. Thanks for the massage, Doochil.

Jindo Dog, you shouldn't be talking big now.

Hey. You're lousy, you bastard.

You got arrested after six and a half. Guess how many I killed.

I can't believe you're playing king here

just because you've killed someone.

You bastard. Your skills are damn poor.

Stab me, you bastard.

Why take out a prop when you can't even stab me? Go ahead!

Quiet down! Get back in!

TAEWON 1-DONG, TAEWON 2-DONG AMDO-GIL

-What are you doing? -Don't move.

Are you insane?

Uncuff me. Now!

Uncuff me.

Stand up.

Give me your phone.

Now!

Stop the car.

Stop it!

Stop the car now!

I understand the situation.

We'll be counting on you, prosecutor.

Goodbye.

Jindo Dog is still alive.

If he was going to dig his own grave,

I didn't have to meet that damn judge.

Excuse me. What are you doing?

What are you doing?

-Go through everything. -Yes, sir.

Ransack even the trash bin

to find any clues to where he could be hiding!

It's facing directly away.

I doubt we'll find anything.

Who knows?

-Keep looking. -Okay.

Breaking news.

The current detective who had been arrested for murder

ran away while being transferred.

At around 4 p.m. today, the Regional Investigation Unit…

See? I was right.

He ran away because he knew he was guilty.

Hey, Dongwoo.

Detective Jin locked the doors and risked his life just to save others.

Don't jump to conclusions.

What...

I was just...

...they're trying to locate him

and will investigate the case openly later on...

Not bad.

You were going to rot in jail, anyway, so why did you run off?

It's where you belong, not me.

Says the wanted criminal.

Being on the run will only get you more charges.

Just hang up, you bastard.

The fire destroyed all the evidence

of the outside force applied to the victim.

No trace of the assailant was left behind.

In this case,

the victim is our last clue.

Hello?

Narcotic analgesics were found in the victim's blood.

Comeine, oxytorone, and hydroorbine.

That much is...

He could've been under severe pain with late-stage cancer,

or he could've been a drug addict.

How much of the blood from the scene do we have left?

We lost a lot of the sample due to heat denaturation.

Do you have anything else to check?

It will be the last time, so you must decide carefully.

- Darn it. - Goodness.

Did they buy you off ,too?

- Just how far up does this go? - Get him off.

Is it really necessary to be careful?

The owner of the blood is just a mad dog who cut off his leash and escaped.

Hey.

Hey, kiddo.

Hey, butane gas. You should thank me for saving your life.

Thanks.

Why, this little... Hey.

What is it this time?

You do that habitually, don't you?

I saw gas bottles everywhere. Do your parents know?

Were there other people who often came to that diner?

I saw some homeless men

from Taewon Station come there to sleep over.

Throw it out!

- Hey! - There!

- Why did you do that? - Who did...

-Oh, my. Hey! -Someone is down here.

-Hey! Hurry over here. -What?

- Is that a person? - Let's go.

-What? -Over there.

What is it that you wanted to tell me?

Why did you call me over here?

I was told to tell you, old lady.

What, "old lady?"

The cop who saved me called you that.

Oh, really?

You should've called me, then.

I was told to tell you in person.

Mm!

Go meet him at the homeless village near Taewon Station.

Oh, Officer Song!

- Officer Song! - Hello.

-Hello. -Look who's here.

It's you, Officer Song.

Right, have you been well?

I wondered who it was.

Oh, I'm all the better from that glass injury.

Look.

You're right. It healed up nicely.

Sir, let me ask something.

Didn't an injured man come here today?

He's tall with big eyes.

Yes, right. Someone new came in a while ago.

But he doesn't seem well at all.

-Follow me. -Okay.

-Move over. -She's here.

-Hello, sir. -Yes, hi.

-Join us for a drink. -It's you.

-Later. -Come on and have a drink.

-Goodness. -He's here.

Don't get up, and stay down.

Let me see.

I'm okay now.

Jeez.

HANKUK UNIVERSITY HOSPITAL SONG SEOL

I'll cut the shirt open.

Jeez, it hurts more.

It will be a little painful.

Stay still. If you get infected, it'll be really bad.

Hey, sweatsuit.

Consider yourself lucky.

She's the official call-in paramedic in this homeless village here.

I'm telling you.

How did this happen?

Cho Doochil...

Whatever.

It's a complicated story to tell.

Sorry, but I don't have an anesthetic.

- Ow! - Don't be a crybaby.

Ah!

One last time.

Done.

I'm not being a crybaby.

It hurts even more.

What time was the sunrise on the day of the fire?

It was 06:32 a.m.

Let's check the footage before, then.

Okay.

The paint factory is located behind the diner at the ten o'clock direction.

The CCTV camera on the outer wall is facing away from the diner.

However,

the fire broke out before sunrise.

So in the dark,

the first flames might have been reflected on the windows and captured on the camera.

The accelerant was lighter oil.

Unlike solid, a liquid accelerant with a low boiling point like lighter oil

emits a strong light when it first ignites a fire.

The ignition got captured.

The flames got reflected on the factory windows.

But what is that?

It might be the ignition source.

IGNITION SOURCE: THE DIRECT CAUSE OF FIRE

But it's too big.

What's with all this fuss?

I don't get why you need these worn-out shoes. Jeez.

That's enough. You should leave now.

If you stay with me, you'll be charged for sheltering a criminal.

How long will you be on the run in that state?

Until I catch the real culprit.

Don't worry.

You know I do that quickly once I set my mind.

Do you really smell a crime or something?

Do you take me for an actual dog just because people call me Jindo Dog?

That's not what I mean.

It's not like I have some supernatural power

to read criminals' minds.

I just work damn hard.

I sleep less than others.

I work harder than others.

Investigating a case is...

biting the dust to put it nicely, or wasting time.

Which pattern are you looking for?

I'm not biting the dust. I'm just cooperating.

Thanks.

What? Which pattern did you say?

Didn't you hear it? I said thanks.

Don't say that.

I don't want to be arrested for sheltering a criminal.

Look for something with a similar police logo.

A lighter oil container?

So, someone sprinkled a flammable here three times?

The pattern says it's liquid.

And it smells like lighter oil.

Hey, isn't this from Woo Miyoung's place?

Yes, why is it here when it's supposed to be in the evidence storage?

Besides, we found only your fingerprints.

Right.

The scene reeked of lighter oil.

As if someone wanted us to notice it right away.

Woo Miyoung's lighter oil container. I hear it was in the evidence storage.

Only the police have access there, no?

You're right.

Think about it. What if someone's after Detective Jin...

An inside job?

That's why I called you out in private.

Anyone you can think of?

None yet.

Hold on. The Regional Investigation Unit?

The RIU?

The shoes.

-Here. -Goodness.

This is just nonsense.

Goodness, gracious.

Why are you helping me? What if I really did it?

As if. You can't even kill a single ant.

I'm a tough guy.

Why do you treat yourself so poorly?

A cop's salary includes his life's worth.

It's the same for a firefighter.

Consider it comradeship.

I found it.

Mister, whose shoe is this? You know?

What?

This one.

I think...

this belongs to Ko.

-Do you want me to call him over? -Yes.

Hey, Ko!

Ko!

What are you doing there?

These shoes.

I smell it.

Right, the shoes.

My husband's pants, T-shirt, and undershirt are all gone.

Sir, we found the trace of Jin Hogae.

He was captured on CCTV at Mapyeong Station.

Gather every man at the station.

-Moving to Mapyeong Station! -Hurry up.

Sir!

What is it?

We have an update on his location, but it's...

Where is he?

Guys! I'm here to turn myself in!

Why that darn...

But it's one plus one.

THE FIRST RESPONDERS

I hope I'm not too late.

I found something, too.

The bloodstains and evidence were all fabricated.

I'm afraid all your evidence is no longer valid.

-This can't be. -What's the matter?

Were you looking for this?

You'll be behind bars for a long time.

If Jindo Dog finds Choi Seokdoo,

it will be revealed that the alibi was fabricated.

We must indict Ma Taehwa for the main crime. Murder.

How can we indict him when he has a concrete alibi?

Only Choi Seokdoo can nullify his alibi. He's alive in one piece.
