"The body does not lie."

This is the absolute proposition of

all forensic scientists, including myself.

That's right.

The body does not lie.

It is the man who analyzes the body

that makes the error.

The man only trust his limited knowledge and intuition,

and thus repeats the same mistakes,

only definitizing his own limitation.

All the while

the body is providing us with a vast number of clues.

He speaks like some religious sect leader.

I say the chairman of some pyramid scheme.

Hey.

What we created in order to overcome this limitation,

is this CODAS right here.

This is a joint–project by the NFS

and the Korea National University,

and is the world's first AI CoD analytic system.

Ohhh...

Ah, what a fine day.

What a fine day!

Oops, I forgot about the most important thing.

With reverent respect...

Alright,

that's enough.

We have collected the CoD's of 120,000 bodies that

have been autopsied in the past 30 years,

and by integrating the elements of pathology,

forensic science, and criminology,

this system can now analyze CoD's, using our Big Data.

Moreover,

our time for analysis has now been reduced profoundly.

But is it credible, without an actual autopsy?

We won't be leaving everything to the system.

The system will perform analysis using the data

obtained from the autopsy.

In other words, we will still need the basic data.

Our biggest concern too,

is whether or not the system is reliable.

Of course.

Let's take a look at this next screen.

These are the results of the simulations we've run

in the past 6 months, under tight secrecy.

When we matched it up with the actual case results...

It has proven to resolve 91.4% of the cases.

91.4%?

That's impressive.

Is that number even possible?

Isn't that third case...

...the Woocheon–dong Serial Murder case?

Ah, yes.

I believe that case is under your jurisdiction.

We're yet to close the case,

so why does it say "completed" up there?

I will talk to you separately

after this briefing.

Huh?

That Gudam Nursing Home case...

Isn't that ours?

We're yet to solve that, too.

Why take our cases as an example without a word?

Quiet.

The system is still evolving as of this minute,

and its accuracy rate will continue to go up.

Once you feel confident about CODAS' reliability,

I hope you'll help CODAS to

attain legal force, in its own right.

That is all I wish for.

Tell Detective Koo to

arrest that worker at that paint plant.

Now!

I hope you will consider it.

Don't worry, but focus on fine–tuning the system.

That was impressive.

Please excuse me.

Sure.

Ah, sir. Thank you for taking your time to come all this way.

I appreciate it.

Mr. Kwak.

That was too harsh on your colleagues, don't you think?

Oh, is this about the case?

I'm sorry, Doctor.

The simulations were carried out in absolute secrecy.

Then you could've tipped us off at least.

Before making a fool out of us.

Ms. Moon Su–an.

Please don't forget your manners.

Then where are yours for Dr. Jo?

Stop it.

Listen, Mr. Kwak.

Yes, it's our fault that we couldn't solve it.

But you could at least cooperate.

Yes, I'm sorry to upset you.

I'll consider that option next time.

Then can you give us the analysis report?

We'll have to re–draft our list of suspects.

That won't be possible.

– Ha! – Pardon?

Our analysis report isn't for submitting to the police,

but for the system.

So please solve your own case at your institute.

Ha! Unbelievable.

What's with him?

Does he think he's above everyone else?

Just unbelievable.

Was he always like that?

He's always stood out from the day he got here.

A smart bullhead.

Should I talk to the prosecution

and get that analysis data off Mr. Kwak?

Just leave it. Let me work on it a little more.

Ah, Detective Lim.

What?

Here.

Goodness, how can you cook,

crouching like this?

I've never been more comfortable in this pose.

– Hey, this isn't bad. – No.

Hold on.

– Isn't that a scalpel? – Yes.

Are you cooking with a scalpel?

– Yes. – What, were you a doctor?

Well... Kind of.

Come on, don't come here to ask me about my past!

– Please. – Well, forget about the story.

You look much younger than me,

but why are you talking down to me?

I...

I get told I look younger than my age.

I'm actually much older than I appear to be.

When you live alongside nature and eat only the good things,

you'll get your youth back like me.

Wow, so does that mean I'll shed years off my face too,

if I live alongside nature?

I wouldn't trust nature so much.

I see.

Alright, let's see. Next, you add this, and...

You see, this is the special sauce I made.

– Oh, really? – Just add this, and...

It'll taste amazing. Just wait there.

Man, that's...

Here you are, go ahead and smell it.

Sure. Oh, wow.

Wait a second.

What was this again?

It smells like that school mop during the monsoon, right?

You're right. But why this smell?

Exactly! That's what it's meant to smell like.

Everything that's good for your body

smells like it.

But that's strange.

Here, have a taste.

Do I have to?

Here you are.

Don't spit it out.

Pffft! What the hell is this?

What is it?

It's weird.

Oh no.

That's not good.

Then we shouldn't eat this.

This is my first time making it, so let's not eat it.

What? But you just said you've made it before.

Don't trust everything that nature presents to you.

Now, why isn't this rice cooking?

So, any other questions?

– I do, yes. – Yes?

So you live in the mountains.

But how long are you going to live this secluded life?

It's all useless, I tell you.

You come into this life alone, and you depart alone.

So you should get used to being alone.

And to do that, you should seclude yourself.

That's the best way to do it.

Oh what?

How many times has it been? Please turn that cell phone off.

Come on, guys!

Oh, it's mine. Wait a second.

– You got a call? – It's my darling. Hold on.

– Your "darling?" – Yes, hello.

– Cellphone? – Hey, darling.

– Darling? – Yes, it's me.

– What... – Yes.

What the hell?

Name, Jang Hyo–yeon. Age, 27 years old.

She died after a fire suddenly started from inside the car.

According to the child who witnessed the scene,

the fire started from her chest.

Not from her surroundings.

But is this even possible?

"Spontaneous Human Combustion."

Simpler, please.

Hey, what's with that arrogant attitude?

What happened to that woman who'd look up to me

with an enthusiasm for learning in her eyes?

You used to be like,

"Dr. Han, what is that?" But look how you've changed!

Just hurry up!

Oh, alright.

"Spontaneous Human Combustion."

In other words, the body catches on fire.

It's a widely–known unexplained phenomenon.

So something like this has happened before?

What's the cause?

We don't know the cause, hence it's a mystery.

If we did, it would be Mister–park not mister–ry. Hahaha!

Ha... Living a secluded life sure has ruined your sense of humor.

Haha, my stomach!

Detective Kang.

– I think you should come see this. – Alright.

I'll call you later.

What, you're hanging up?

One more minute! 30 seconds! No, ten!

Sorry.

Oh, come on!

Wait a second.

Spontaneous human combustion?

No way.

No... No way! It can't be. Ha!

Sir, your rice is burning.

Sir, your rice is burning!

Take that pot down!

– Um... – Take that pot down!

– Take what down? – Wait.

Ah, hot! Hot!

Don't panic.

Just dunk it in here to cool,

and I can just scrape off the scorched rice.

Uh, can you switch off the camera for a second?

Hey.

Why are you glaring at me? Hmmm?

You're not a hermit, are you?

I never said I was a hermit.

You deceived your age, didn't you?

I'm thirty–three.

Why you...!

Stop right there, you bastard!

Spontaneous human combustion...

This is ridiculous.

I don't believe it myself,

but maybe it is.

Dong–geun.

What makes up 70% of our body?

– Water. – So can it catch on fire?

But we have fat, too.

Are you talking about the wick effect?

Yes.

The fat in our body could act like the wick of a candle

and burn the whole body!

I even saw a video of

where they experimented it on a pig.

For that to happen,

the victim needs to have lots of fat like the pig

and at a high ratio, too.

Not only that, his body needs to be continuously heated.

It's here.

Let's have a moment of silence.

There's no evidence that the fire was started from outside.

From the burns,

it's clear that the fire was started within.

But how, from within?

Let's go in.

As I thought,

it was the organs that caught on fire first,

and not the skin.

And the original point of ignition?

From the burns,

I'm suspecting the liver.

– And the cause? – The wick effect?

Well, the liver is high in fat.

Enough already!

Was our victim suffering from a rare condition?

Not that I can note, from the inspection.

We'll have to analyze in depth.

Give them the samples.

Yes, Dr. Jo.

Um, Dr. Jo?

Why don't we call Dr. Han?

Forget it.

Let's not disturb someone

who's having a good rest.

What brings you in here?

The autopsy data from the SHC case.

I'd like a copy please, for CODAS.

Because our team is on this too, as of now.

This is under our jurisdiction.

We can't allow a joint investigation.

Here are the orders from the prosecution.

Ha!

Give him all the data there is.

Thank you, Dr. Jo.

His cockiness has gone through the roof.

Well, let's see what he does with it.

Clean up, then.

Yes, Dr. Jo.

(Cause of Immolation Still Unknown Will it remain a mystery?)

(Sanseong Crossroads Fire, Cause Still Unknown)

We've received all the data from the institute.

Begin, then.

42 minutes.

No changes. Nothing!

Ha! What fire?

Ugh, I have pins and needles... Ugh!

Let's just finish boiling that meat.

I'd lost it.

Spontaneous human combustion? Please.

Ah, hot!

Ah, hot!

Oh, please.

We're yet to receive the results back,

so do we really have to?

The public is in panic and the media's making a deal out of it,

and it's gotten out of hand.

The higher–ups ordered it, so please.

Alright, sir.

Oh, and I have one more

favor to ask you, Dr. Jo.

Did you hear too, from the Chief?

Of course.

The results are yet to be back,

so will you be alright?

It's fine.

I'm only going to discuss our primary findings.

You seem to be less confident than

when you were on the Gudam Nursing Home case.

I don't think the journalists will be satisfied

seeing you in that state.

If they won't be,

you help me out.

Alright, I'll do that.

Then after listening to your valued opinions,

I'll fill in for any missing details.

Ha! Unbelievable.

Man, how incredible.

He can't make it any more obvious, can he?

Oh, shut up.

Come on!

Come on, please!

God, I thought we lived in the era of 5G.

So why am I not getting any signal?

Regarding the mysterious immolation case last night...

Ah, there!

Dr. Jo, who performed the autopsy will give her opinions.

(Dr. Jo, Chief Forensic Scientist at Korea National University)

Dr. Jo! Dr. Jo! That's our Dr. Jo...!

My goodness,

why have you lost so much weight during the time I've been away?

Even if no one's realized it, I can tell!

The cause of death is suspected to be immolation,

and we found nothing else that

could have caused death.

There were no traces of external contact with fire,

and the original point of ignition is

suspected to be the liver.

Then are you saying someone set the victim's liver on fire?

I said there were no traces of external contact with fire.

But that just doesn't make sense.

How could the body catch on fire, then?

Isn't this what they describe as spontaneous human combustion?

Spontaneous human combustion

has no scientific ground.

But there's nothing else to explain this, is there?

Are you sure there were no errors with the autopsy?

God, those bastards are barking away

when they know nothing!

Let me re–iterate,

but SHC, or spontaneous human combustion

is an urban legend that has no...

It may not be an urban legend.

May I add in something?

Aren't you being too reckless?

I don't pitch bean balls.

I always pitch right into the strike zone.

Then please.

Please let me introduce myself, I'm Kwak Hyuk–min,

at Team CODAS, an AI CoD analytic system.

Did CODAS produce a result?

Spontaneous human combustion...

Or to be more specific, an atomic explosion from within the body.

What?

"Atomic explosion?"

Ha! Unbelievable.

I'd rather believe the Terminator lost his thumb

while being seen by a physiotherapist!

The human body is naturally radioactive.

One example is the

41 million gamma rays

emitted by potassium inside our cells.

Usually they don't cause problems,

but according to CODAS' analysis,

if our body's system is disrupted for specific reasons,

they could collide with the heavy hydrogen in our fat tissues,

causing what is similar to an atomic explosion.

Then what was the cause in this case?

According to the records,

our victim suffered from chronic kidney disease

and had symptoms of fatty liver due to diabetes.

The lipids in liver are two to three times richer

in heavy hydrogen compared to other fat tissues.

And if she had high levels of potassium in her blood

due to CKD, then that would generate more gamma rays

and thus lead to

an unusual incident like this one.

Then you're saying

SHC does exist.

From our analysis, we say it's possible, yes.

Who the hell is that bastard?

Why's he telling bullshit

with his low voice, and in a serious tone, too?

Who is he anyway?

Ah...

My muscles...

My muscles, wait!

Then just change it over to the left hand!

We decided to make CODAS' analysis public.

I know you're upset, but please understand

and help Kwak with whatever he needs.

Oh please.

[tvN Asia ver.] Quiz From God 5: Reboot E01 Ripped & Synced by ordinaryguy92

Ugh, this is making it worse.

This singing is making it worse!

Who do I have to clap with here, huh?

God, I'm going to die from loneliness!

Ugh, please.

Who's there?

Is somebody there?

I knew this would happen sooner or later.

Excuse me?

I don't know what you have against me,

but please go away, alright?

Please go away!

What... Why are you laughing this time?

Are you some bipolar ghost or what?

Oh what?

– Who's there? – Ha! Bipolar ghost!

Detective Kang, please!

God, that was so funny.

You know that's what I detest the most.

Of course, that's why I pulled that prank.

Come on!

I know nothing scares you,

but you still shouldn't come here alone, at this hour!

Well, I have this.

What, you're going to use that to shoot the ghosts, are you?

You're yet to eat, right?

I'll make something for you.

Mushroom rice, mushroom salad, pickled mushrooms...

Anything but those, alright?

God, you always read through me!

I'll make you something else, then.

Anyway,

that's why there was all this tension this morning.

So in other words,

you got done again by CODAS, did you?

Hey,

done by what?

Well, but you have to admit.

The Woocheon–dong Serial Murder and the Gudam Nursing Home cases.

They were both solved by CODAS too, weren't they?

But uh...

Can we trust its results for this case, too?

Yes.

It sounded pretty valid.

Dr. Jo...

Why couldn't she call me at least once?

She wanted to,

but she didn't, so she won't trouble you.

Come on, how is that troubling me?

But it's not like you're officially back,

so I guess she felt bad about

calling you up to ask.

Ha! Is she a living Buddha?

She really is, isn't she?

By the way,

this CODAS or whatever...

Is it really that great as they say so?

It's surpassed our expectations.

I think they got a hefty fund, too.

How strange.

But that just can't be.

Because from what I heard at that press conference,

it was just total crap!

Spontaneous human combustion,

and what was that? Atomic explosion?

That's 100% bullshit.

Then, uh...

Can't you drop in

and give us a hint?

I guess I shouldn't have brought it up.

I wasn't being considerate.

Come on!

I know you said it because you're frustrated.

But to be honest,

it's me who really wants to be back.

But...

But if I return,

even I'm scared now about

what will happen this time.

Because I really don't want to be a burden to

Dr. Jo, or you.

While you were on the run,

do you remember how you tried to distance yourself,

saying you didn't want to be a burden to me?

That's when it was tougher for me.

So don't ever think that way.

It's not like I don't want to,

but all that happened then...

Nothing had gone how I'd wanted to.

Alright, I see.

Once your situation improves

and you feel much better,

come back to us then.

And don't worry about me.

Because I've reached nirvana when it comes to waiting.

Oh, I knew it.

No wonder it was going so well.

Yes, Detective Lim.

Where?

My God.

That yesterday, and now this...

Ohhh...

Let's eat.

Ah, that looks delicious.

Thanks for the food!

Take your time with that!

Alright.

Just hang in there, just a little more.

I think Detective Kang is almost there to

prove your innocence.

But uh, Dr. Jo.

You really shouldn't meet with a fugitive back door,

and buy him lunch like this. Alright?

What if the higher–ups find out?

What if they do?

They'll just fire me, and I'll open a chicken shop.

Ah, that's my Dr. Jo!

A woman of spirit, like an Olympian!

– Jin–woo. – Yes?

To the late Professor Jang,

Detective Kang, and I...

You're like family to me.

Why, I'm willing to do anything for you.

I'm not worth it.

What was that?

But you're family!

Family that needs no words.

Haha...

A burden like me, family?

Jeez, Dr. Jo.

You sure have a weird taste in families.

God, it's hot in here.

Yes, Jin–woo.

Make sure to

crack jokes,

and smile, Jin–woo.

Oh man.... Dr. Jo.

Why, that woman!

Tsk, I should go buy a hard drive, then.

But I'll have to eat before I do.

Dr. Jo, you just wait! Because I'm coming!

Dr. Jo.

Ah, Mr. Kwak.

When will I have that body with just the legs?

In 30 minutes, I think.

Why? You want the autopsy data again?

Yes, please.

Mr. Kwak.

Yes?

I'm not talking to you with a smile on my face,

because I've forgiven you for the past.

Why did you have to bring that up now?

I'm telling you,

to be a human at work.

Tsk, that innocence of yours...

You never change, do you?

Speak for yourself.

Wait just a second.

I'm sure this is the place.

Why's it changed so much?

CODAS.

Ah, so this is CODAS.

Let me see...

Well, it just looks like some expensive internet café.

Hello.

What, is this bulletproof glass?

That's real thick.

Excuse me, but who are you, mister?

Mister? Hey, do I look that old to...

Maybe yes.

Are you...

Professor Han Jin–woo?

What, you know me?

Oh my goodness!

Why, of course!

I was a student in your class.

I'm Jung Seung–byn, a Pathology major.

Oh, oh!

I see. Nice to meet you.

Celebrities just have that aura

wherever they go, huh?

So, uh... Can I take a look around this place?

What?

Data from 750,000 cases?

Yes.

Based on this Big data,

the 130 autopsy protocols within the system will

each produce different scenarios for a final comparison.

So you're saying...

Simply put,

it's like 130 forensic scientists holding a debate,

each with their own opinions.

That's right.

So this is Deep Learning that I've only heard about.

Man, incredible!

But I say it'll be more incredible if you play games with it.

Who said you can allow just anyone in here?

I've heard that voice before.

Dr. Han Jin–woo?

Ah!

Guy from the conference!

You look much better...

...on screen, actually.

Anyway, nice to meet you.

You're that guy with a name

that's difficult to pronounce...

Mr. Kwak Hyuk–min, right?

What brings you here?

Well, I was just passing by

so dropped in for a tour.

I heard you'd been living a hermit life.

Well, uh... I'm out to buy a hard drive today,

but my place...

The postman doesn't deliver to my address!

Since we're on the topic,

if you have an external hard drive to spare...

If you no business here, please get out.

Don't be like that.

I'll pay you the market price for it.

So if you have one to spare, give one to me.

I have a 2TB one.

Please refrain from coming here from now on.

Well, uh... Alright, then.

By the way, your face is quite pale.

I dug up some nice wild herbs the other day.

– Just have a little of... – Please get out.

Fine. Alright, then.

But this is really good for you, you know.

Well, I'm off.

Oh, that's right.

About this "spontaneous human combustion" talk.

What was it that you said?

Oh.

Atomic explosion.

That was the funniest joke

I've heard in three years!

You're trying so hard to be funny, aren't you?

Atomic explosion. Haha!

What are your grounds for saying that?

Not telling you!

Jung Seung–byn.

If you allow any more unauthorized personnel in here,

you're out.

Yes, sir.

Another body like last time...

What are we to do? Alright, a...

A moment of silence!

Dr. Han!

What,

when did you move the office?

Wasn't our old office

where CODAS is now?

And...

What's with this place? Is this a public bath?

Why all these tiles?

God, the smell of mould from between the cracks!

What brings you here, all of a sudden?

What's this? What's this?

God, you always appear like this.

You little, you...

Oh please.

What's with this rough welcome?

I'm only here to buy an external hard drive.

Alright, say hello, everyone.

This is the famous Dr. Han Jin–woo.

This is Officer Moon Su–an,

and this is Lee Dong–geun, our researcher.

I'm Moon Su–an. I heard a lot about you.

That you're a genius.

Yes, it's nice to meet you.

But have you ever been conned by a genius?

Because you're so callous.

I don't really trust geniuses.

Only perseverance and diligence.

She bites, doesn't she?

But her nickname is

Han Jin–woo Junior,

because she's our top expert on rare conditions.

She got her Ph.D. for that, too.

She really filled in for your absence, you know.

– Did she? – Yes.

So it's the nickname that you don't like so much.

"Han Jin–woo Junior."

Well,

there's no reason to like it, is there?

Ah, it's such an honor to meet you, sir.

I've been wanting to meet you, you know.

Can I shake your hand?

Honor? Please.

But it is an honor to meet me, isn't it?

By the way.

I only came to buy an external hard drive,

but a body just seemed to have

arrived, just in time!

What a coincidence. Just in time, right?

Why only this?

Right?

It just stopped at the knee.

What if this didn't happen just naturally?

What do you mean?

If you look closely at this body,

it's like it was planned, all along.

And not something from a natural fire.

Wow, you're really good!

So she is a talent.

See, that's what I thought as well.

This body is just screaming it out, isn't it?

That it just spontaneously caught on fire.

So take a look at me, it's saying.

Something's definitely fishy.

But why opt for a method

that's so obvious?

Oh, my system's frozen,

because I haven't used my brains for a while.

Enough with our guesses,

let's go in.

Whoa, wait.

A magnifier, please.

– Here. – Did you find something?

Take a look here.

Right here.

Where the burn ends.

Around the lymphatic glands.

They should remain white even after rigor mortis,

but here, they're purple.

Our first victim, Ms. Jang Hyo–yeon.

Has her body been returned to her family?

No, not yet.

That'll happen this afternoon.

Okay, then let's take a quick look at her.

Zoom in on the popliteus muscle.

Yes, sir.

Purple lymph glands?

Bring up the data for the endocrine system.

I'm seeing discoloration here, too.

Are they different from lividity?

They are.

Blood shouldn't pool here.

But as you stated in your primary findings,

no sign of any rare conditions.

I thought, just maybe.

We'll have to analyze the manifested phenomena.

Dr. Jo.

Yes.

We're here from Internal Audit.

What's the matter?

I'm only here to purchase an external hard drive!

Whatever your reason,

you are banned from entering the premise.

In fact, he's already breaking the rule, being here.

What, breaking the rule?

Can't he just drop in to say hello?

This is not a café,

but a public institution.

It wasn't Dr. Jo.

It was me who asked Dr. Han to come in.

If something should happen, I'll take responsibility.

What, it's not like I'm a spy or anything.

Why do you have to be so uptight?

Rules are rules.

We'll have to report this to the headquarters.

And what?

Will that mean a penalty?

Fine, I'll take it!

That'll be up to the HQ to decide.

We're only here to confirm he was here.

Please leave the office, then.

Oh, them and those rules...

By the way,

who could've known he was here to report him?

Exactly.

That, uh... Kwak. Kwak Hyuk–min!

What, you bumped into him?

Yes, on my way here.

He better watch it,

because I'm going to get my bloody revenge!

Boy, am I glad to have you here!

Whoa, wait!

Intestinal rupture! Intestinal rupture!

My joints!

Sarikata oleh tvN Asia Ripped & Synced by ordinaryguy92

You just messed with my intestines...

Are you alright?

Concussion...

Let's first visit our first victim's place.

Do you think it'll be alright?

Surely Audit can't follow us all the way there, can they?

I need to drop by the station before we do go.

We have a new officer joining us.

Really?

I hope it's someone who's fast and on it,

like Detective Bae and Detective Park.

Hello.

Ah, hello.

Hello.

We'll be in your care, then.

Sure.

Did someone offend you?

Oh, no.

I'm just a little shy and my voice is tiny...

Sorry.

You know what our team does, right?

Yes, well...

Mysterious death,

autopsies, and...

God, I can't hear you! Speak louder!

Alright, rare conditions!

Rare conditions.

– Yes. – Alright.

Then for today, stay in the office and learn your duties.

And how about a dinner together to welcome you onto the team?

Well, about that...

I'm really shy, and... Sorry.

What?

God, this is so frustrating.

You should get a megaphone for him.

Um, Detective Kang?

I'm really sorry, but can I be excused tonight, too?

Why?

I'll get kicked out for sure

if I miss out on class today.

Class?

That's right.

I take creative writing lessons.

My dream is to write crime scene investigation series.

Oh, I see!

Then why not write about me?

See, I've had many ups and downs

in my life.

The story should begin from when I was two.

I guess we'll have to postpone the dinner, then.

Go for your class.

Thank you, Detective.

I'm into dramas, too.

– What was that? – I'm into dramas!

Oh, so you're into dramas.

Please, louder.

Gosh, I love this team. You've all grown on me.

I mean, all these different personalities!

What's with that expression?

About Dr. Jo.

She's going to re–request for your reinstatement.

so let's hope for good news.

If they say no, that's fine.

By the way, about your car...

What, is your windshield

a mass burial site for bugs?

Why so many dead bugs?

Oh.

They were killed last night on the state highway

while I was on my way to you.

– What is it? – I smell alcohol,

and it's making me feel good.

This is...

Oh, so you switched your washer fluid to ethanol.

But when did that happen?

They banned methanol starting this year.

After I changed it to ethanol,

I'd smell alcohol

whenever I use the washer fluid.

I see.

Ah!

Now that I smell alcohol,

I really want some soju and some intestines.

Let's go get some after we're done.

Alright!

She lives in a fine place.

Let's see...

Best Trust Hospital.

These are the drugs for her chronic kidney disease.

They seem quite old.

But the most recent ones...

(Prescription Medicine)

Ah, this and this.

This is an antacid,

and this is an immunosuppressant.

Why these two?

Why are you checking the fridge?

Banana,

perilla leaves,

salted roe,

and seaweed...

She lives alone, does she?

Yes.

I think Ms. Jang Hyo–yeon

had a kidney transplant.

But CODAS' report said

her endocrine system didn't look good.

I think that's because CODAS only held

her old medical history.

The most recent ones have been omitted, I think.

And your grounds?

Well...

Patients with chronic kidney disease

should stay away from food high in sodium and potassium.

But look here.

All full of sodium and potassium!

And...

These, just now.

Antacids and immunosuppressants.

These are taken after a transplant to

reduce the risk of any complications.

Then this atomic explosion theory

doesn't make sense.

Exactly!

I just need one.

One more.

So...

Ethylene.

Ethylene, with a catalyst...

That's right.

Then...

Trimethylaluminum.

Trimethylaluminum.

They banned methanol starting this year.

After I changed it to ethanol,

I'd smell alcohol

whenever I use the washer fluid.

Ethanol.

Ethanol...

Detective Kang!

Detective Kang, wake up!

Hurry up!

What is it?

I just love you!

I just love you to death!

Why call me out so early in the morning?

And Mr. Kwak, too.

Please at least tell us the reason.

Once you're in my office.

Here.

What is this?

Dr. Han, didn't you hear what Audit said?

Good morning, Chief.

And standing right next to him is...

Oh, the tell–tale.

I'm about to tell you the reasons why

we need Dr. Han back here.

Reasons? What reasons?

I won't be bought. No.

Oh, really?

Then I won't say it, either.

See, I discovered the key clue to this

spontaneous human combustion case.

Forget it, I'm leaving.

I should go grab some macarons instead.

Because I really need a sugar kick!

Excuse me, Dr. Han!

Come on.

Why are you always so impatient?

Are you sure about that?

That she wasn't suffering from chronic kidney disease?

Yes.

We have circumstantial evidence telling us that

there's a high possibility she had a kidney transplant.

CODAS has unfortunately made an error,

because it held only her old medical records.

Then what was the cause of the fire?

What immolated her body was

ethanol.

Ethanol?

The dash cam inside our victim's car was

unfortunately totally destroyed,

but fortunately, we still had the

dash cam from the car next to her at the time.

– Dong–geun? – Yes, sir.

To wipe dust off her windshield,

Ms. Jang started the wipers.

And according to our analysis,

it was ethanol she used as washer fluid.

Then...

What was it that reacted with this ethanol?

The purple substance from within her lymph glands.

– Dong–geun? – Yes.

There's a hardly a case where lymph glands end up like that.

No.

For example... If you get a tattoo,

the ink from it can also discolor the lymph gland.

In other words, the fine particles from the ink

breaks off and circulates

until it is absorbed by the lymph gland.

There were no tattoos on the body.

No.

It wasn't a tattoo.

There were nanograms of a purple chemical substance

that were injected into Ms. Jang's body,

which will not disintegrate but

be absorbed by the lymph gland.

I'm sure CODAS has detected it, too.

It was a chemical substance synthesized from manganese,

found in purple pigments, and titanium dioxide,

which helps maintain its purple color.

Ah!

But that's about where it got to, didn't it?

What, so you found something?

Who am I?

I asked, who am I again?

What's with the atmosphere?

I'm Han Jin–woo!

Stop acting up!

Oh, alright, alright.

Well.

I traced the fire ignition

and found the source of the ethanol

and the chemical reaction that happened.

But most of all, I found out what caused it.

The ethanol gets absorbed by the liver,

and the liver breaks it down, like it does with alcohol.

And during this detox process,

we get acetaldehyde, as you're well aware already.

Bu this is where the fun starts.

This acetylaldehyde

gets broken down to ethylene and oxygen,

by this purple substance I just told you about.

And it also catalyzes the RedOx of aluminum hydroxide,

which is found in antacid, and ethylene.

Which, in the end,

leads to trimethylaluminum.

This is class–1 hazard,

which catches on fire when in contact with oxygen

and explodes when in contact with water.

Still,

there's not enough oxygen in the body to cause fire.

Come on, I just said

we get oxygen when acetylaldehyde is broken down.

So the conclusion is,

this trimethylaluminum and oxygen meets in the liver.

And so from the liver,

you get fire.

In your opinion, Mr. Kwak,

is this possible?

I would say

it may just be possible, yes.

Come on, it's not "may,"

it's completely possible!

Then where do they use this nanocatalyst to

produce trimethylaluminum?

According to my findings, there are just three companies

that manufacture trimethylaluminum.

It's a class–1 hazard,

so all companies take special cautions

and they must report to relevant agencies when using it.

So are you investigating these companies?

Detective Kang Kyung–hee is already on it.

So, Chief...

What's your decision?

About Dr. Han...?

Three months.

– Pardon? – A three–month,

temporary contract.

But why three months?

And,

if you cause no trouble during these three months,

you will be officially reinstated.

Well, I'm a little disappointed, but...

Thank you.

Please excuse me.

Oh, I was about to call you.

What?

Thankfully, the sprinklers were in operation

and we didn't get a complete combustion.

Did you note anything when you discovered the body?

We smelled alcohol.

When we opened the door and came in.

I knew it, so it's ethanol.

Wait a second.

What is it?

This scar means he's had a kidney transplant.

So we have an important commonality.

Transplant.

Let's see, then...

What could have acted like that washer fluid?

That!

Get me a sample of the fluid in that humidifier.

This is an antacid.

Antacid contain aluminum,

so aluminum, ethanol...

We also have our nano–catalyst,

so of course you get fire.

Um, Detective.

We just received a call.

Sorry?

We just received a call.

Ms. Jang Hyo–yeon

and that Mr. Shin Seong–guk...

They went to the same hospital.

Um, the...

The Best Trust Hospital.

Yes, that place!

So you knew already.

Why do you have to show

such useless, excessive disappointment?

Then according to our findings,

they probably underwent surgery at the same hospital.

(Best Trust Hospital)

Jang Hyo–yeon, Shin Seong–guk.

You know these two patients, don't you?

How strange.

They were both patients here,

and seemed to have underwent surgery here, too.

So why no records?

Well, that's probably because

they didn't receive the surgery at our hospital.

They were on antacids.

Then what, you didn't prescribe them, either?

Are you sure these records are correct?

Those records are correct, yes.

If it's not on the record,

it means we didn't prescribe it to them.

Look.

There's nowhere else but this hospital

which is capable of prescribing it to them!

Are you sure these records aren't forged?

Forged?

Our principle is transparency!

Okay. Fine!

What about their mandatory daily diaries, then?

Not the printed stuff,

but the handwritten stuff.

I have nothing against showing them to you,

but I'll need our head doctor's permission first.

Then please get his permission.

He's currently in Hong Kong for a seminar.

And our vice–head is currently on holiday.

But I'll let them know and once I hear back from them,

I'll let you know.

Alright.

They probably underwent surgery and received the prescription

at the hospital that they're regulars at, right?

Exactly!

I mean,

the fact that they attended the same hospital...

That's saying something!

We need to search that hospital,

inside out!

By the way, where are we going?

Excuse me,

but please all move to...

May we ask for your cooperation, please?

(Staff List)

I'm sorry.

We were going to report it,

but we've been delaying it...

Come on, this is why you should've reported it sooner!

So what's the damage?

5 milligrams of nano–catalyst.

Wait, what?

You're missing nano–catalysts?

And as much as 5 milligrams, too?

What, isn't that why you're here?

No.

We just dropped by.

Oh man...

When did this happen?

The second day of last month.

And your suspect?

An employee suddenly quit and vanished after it went missing.

He was a student.

You got a delivery.

(Chinese Food)

Here, eat.

We received something from the station.

Jang Hyo–yeon, Shin Seong–guk.

We tracked their call history,

and there was this one person

that they'd both been talking to.

But it's a burner phone.

Is the number still available?

Yes, and we're currently tracking it.

What do you want this time?

Call that bastard.

Before that, where's my daughter?

Is she safe?

Enough already, just call the bastard.

Only then

will your daughter live.

500 meter–radius... That's not a large area.

The owner of the phone has got to be in here.

So open your eyes wide and search for him!

Oh what?

What's with this?

What could have turned a genius with a bright

future ahead of him, into a monster?

And why didn't he

kill his victims like last time?

Maybe...

He wanted to show off his methods this time.

But more importantly,

I have a feeling that

Min Byung–tae won't be our last victim.

I'm sure he has a final target

who's at the center of all this.

I only killed those who deserved to die.

I feel no guilt,

nor have regrets.

– No! – No!
