Original subtitles

Who are you?

- Who are you? - Darn.

Keep your voice down.

I have something for you, so come here.

Come over here.

Darn it!

(Doctor Detective)

(Episode 4)

Look at that. There you go!

- Are you going to work? - Yes.

Mommy! Mommy!

Mommy...

Seo Rin!

- Give her to me. - It's okay, I'll carry her.

Mr. Choi, if you take Seo Rin out like this without telling me,

Chairman Choi will be very upset with me.

Ms. Kim, it's all right.

I'm her dad.

Mommy.

I'm so relieved you're okay.

What if that car alarm didn't go off?

But I don't understand.

You heard the car screeching, right?

Then does it mean that pervert ran away?

It's probably not just a pervert.

Were there two people?

- Really? - No, it was just one guy.

Ms. Byun, install security cameras and streetlamps within this month.

- Okay. - Let's go talk.

Were there two people?

Who are you suspecting right now?

Don't tell me it's TL.

I'm not sure about one side, but the other side seems like them.

I had a bad argument with Choi Tae Young yesterday afternoon.

Come on, no way. He has a social status to maintain.

Excuse me.

- Min. - Hi, Joong Eun. It's me.

- Did you see my text? - I did.

Please look into it for me.

I'm sorry for asking this type of favor.

It's okay. I don't have a shift this afternoon. Let's meet.

Let's meet and talk. I'll go see you.

Min, wait...

Does it taste good?

Of course. It's civilian food.

So am I fired from UDC now?

Of course.

You assaulted someone during an epidemiological survey.

Min Ki, it's time for you to go.

- Did you think I'd say that? - "Did you think I'd say that?"

Personal jinx. You're quite sharp.

Here's the deal. A salary cut plus...

taking full civil and criminal responsibility.

- You better accept that. - Yes, whatever.

Did the results of the analysis for that sack I brought come out?

It's not the time for me to be like this. I should get going.

My goodness.

He came to his senses after spending a night in jail.

(A global inspection agency that leads innovation)

(Undiagnosed Disease Center)

Jin Hak. Jin Yi is in the lab, right?

Wait, Min Ki. I have good news.

The dashcam on that jerk's car wasn't working.

- Really? - I guess the card wasn't fully in.

So you'll only be charged with...

assaulting that piece of trash. That's it.

What a relief.

I must've lost my mind.

Do you know how much it costs to repair that car?

You don't have to worry anymore since luck is on our side.

Come on, Joong Eun.

My family wouldn't do something so lowly like that.

Last night,

a car that had its plate covered tried to hit me.

To be precise, I think it was meant to scare me.

I had a bad argument with Tae Young yesterday.

Why did you argue with him?

It's obvious.

He just wants me to lay low and stop working.

My brother wouldn't go that far.

You're the mother of his child.

It's because he loves you so much.

If he keeps loving me like this, maybe he'll kill me next.

Perhaps.

Perhaps.

Can't I even crack a joke?

He can never hurt you.

He hasn't gotten over you.

He's just an innocent fool in love.

Oh, right.

Joong Eun, try some of this.

I bought it thinking of you.

These were on sale. They were displayed outside.

I'll eat these. You can eat the expensive ones.

It's true. My family is unusual, so I'll look into it for you.

But my brother is normal.

And he really hasn't gotten over you.

I hope you're not mistaken.

So you mean that everyone is on my side except for the manager?

I'm glad you brought that up.

Don't you worry. I'll take care of everything.

Mr. Kim's locker is in here.

He also gave his consent for you to look inside.

He went home after today's morning shift.

You can trust me.

(Kim Young Han)

His peak expiratory flow rate isn't much different,

and I don't think his asthma is due to the flour either.

This case is a bust.

Look carefully, Min Ki.

Why don't we just sue the owner of this place...

on charges of assault and blackmail?

Are you kidding me? Do you think we're lawyers?

Why are you getting angry?

I'm just saying we should be open to every possibility.

What is that?

Goodness.

- Really? - Yes.

Have some bread.

You went to the bakery again?

You should get some rest. You must be exhausted.

Did you find anything?

This is what Mr. Huh asked for. We found nothing.

(Analysis Result)

Did you see Mr. Huh?

He got all angry because we didn't find anything.

"Other organic matters".

That's not harmful to the body, and we only found a tiny speck.

Let's run a detailed analysis.

It may not be harmful on its own,

but it may not be the case when it is heated.

Let's just make sure.

Sounds good. Okay.

Doh Joong Eun!

Why aren't you taking care of Huh Min Ki?

How many times did I tell you to take him with you to the site?

Look after him, will you?

He keeps throwing fits,

saying he's always left out and lashes out at me.

And by the way...

Hey.

Did she just ignore me?

Gosh.

What are you doing on our property without a warrant?

Well, I found a lot of bread lying around...

since this is a bakery...

for crying out loud.

Forget it.

Why did you scrap all that bread piled over there?

Do you expect me to tell you everything regarding our business?

It's shady. Why would you throw away food?

Well, that's confidential information.

Why, you little...

Who taught you to act like that?

Please leave.

Fine.

Just let me have one bite.

Let me have one bite.

One bite, my foot. I'll give you a whole bundle.

Excuse me, give him some bread. Help him out!

Hey, stop right there!

- Don't you dare touch me! - Come with us, sir.

I'm practically a public official, you jerks!

- All right, sir. - You know what?

- Goodbye, sir! - I have the right to investigate!

Were you kicked out?

Did you see that?

Good job.

I know things can get tough.

Why?

I can't stand it when you get all soft!

Just be yourself.

Take a look at this.

Something doesn't seem right.

I thought the bakers were all on your side?

Why didn't you ask them to bring one over?

They've got them piled up in the warehouse,

all locked up.

Those jerks.

These were on sale.

They were displayed outside.

I'll eat these. You can eat the expensive ones.

Min, can I have that bread?

(Undiagnosed Disease Center)

Please have it analyzed.

Okay.

There.

I'm sure the same substance will show up.

It could be what caused the asthma or the precursor.

(Precursor: a substance needed to create a chemical compound.)

How could you leave me like that?

You embarrassed me.

I'm sorry.

Even if we don't find anything,

I'm going to report it to "Food X-Files".

Why would you throw away food?

It could only mean they messed around with it. Don't you agree?

"Messed around"?

Messed around...

Melamine.

- It's melamine. - What is?

The tip-off for "Food X-Files".

(Melamine: an organic nitrogen compound used for making resin.)

(Inn)

(Ms. Doh Joong Eun)

Please...

The number you've dialed is unavailable.

My goodness!

Hey, keep your door locked.

How safe are you expecting it to be?

You could have given me a call!

Your phone's on silent, isn't it? I called you five times!

Do you have any snacks?

Gosh, there's nothing to eat around here.

Do you know this number?

I have two missed calls.

Isn't that a payphone?

A payphone? Who could it be?

Do you feed on books? Why is this here?

Whelks!

What's wrong with this? It must have expired.

Are you crazy?

This is expired!

Let's get hangover soup delivered. Three bowls.

Please spare me.

- Would you like some more? - Yes.

Here.

How's the asthma case going?

We haven't found the cause yet, but we're looking into it.

I heard you requested an analysis?

Don't get into anything irrelevant to the case.

The asthma and finding the substance that caused it.

That's what UDC is in charge of.

We have to look into the circumstances, too.

That's not within the realm of science.

We're considered social science.

Did you get that from Huh Min Ki?

He's not that bad.

Gosh, have you bonded as a team?

It's good to hear that he has gotten your approval.

I wouldn't call it "approval".

Sure.

Hello?

Why?

Is it an emergency?

What's going on?

Mr. Ko,

if the cat got hurt, you should've gone to the vet,

not call for me.

It's too late.

Please, help her out and tend her wounds.

I thought something bad happened.

You do it.

My license is suspended until next month.

Hey! It's just a cat! Who cares?

Just help me out, Ms. Gong.

She's better than me.

Please...

Be careful. She's a bit sensitive.

- Okay. - Here. Be careful.

And Mr. Ko,

you can't keep causing trouble like this.

You're the one who's supposed to be here to help me out,

but if I have to keep helping you...

My stomach... It must be from the shock.

Ms. Gong...

You missed this side.

Why is your hand so chapped?

What perfume are you wearing?

I just...

Shall we have a talk later on?

Yes, sir.

Come to my room.

I baked it this morning, sir.

I've had...

too much to handle these days that my body feels so weary.

Did you drug me?

How long have you been working here, Mr. Kim?

About... four years.

So you've been working here for four years...

and were you trying to be considerate...

by drugging me?

My body feels so weary.

- Man Soo! - You called for me, sir?

My body feels so weary. I should play some golf.

Yes, sir.

- Go bring my clubs. - Sure.

Wait, hang on.

I have the balls right here so just bring the clubs.

- Yes, sir. I'll go bring them. - Okay.

- What's the par on this? - It's par three, sir.

Okay, I'll start with the seven iron.

I'll grab the seven iron for you, sir.

Mr. Kim.

This is a par three course, so you must do a good job.

If you do well,

I'll forgive you for putting drugs in the cake.

Do you want a permanent position?

It'll probably make you happy, right?

All right, then. Here we go. Right here.

Darn it.

The ball shouldn't move.

I said I'll give you a permanent position.

A stable salary until you retire at 67...

and a 300-percent bonus twice a year. You don't need any of that?

Yes, good.

All right, that's great.

- Nice! - Nice! Bravo!

- Well done! - Nice shot, sir.

- Bring another ball. - Yes, sir.

Putter.

- Here, sir. - This is for birdie, right?

- Yes, sir! - All right.

Sir.

- Please stop. - Are you crying?

Stop, please...

Don't cry. You're ruining that pretty face of yours.

Why are you crying?

Watch closely, okay?

Open wide.

Open wide.

Eat it.

Eat it!

Okay.

- Let's get ready to open the store. - Yes, sir!

Get ready to open the store!

(Undiagnosed Disease Center)

(Asthma caused by pesticides, 87 percent)

(Asthma caused by flour, 29 percent)

This is 29 percent.

Does that mean the flour isn't the cause?

Min Ki, try that with pollen.

- Pollen? - Yes.

Gosh, seriously. Pollen causes allergic rhinitis.

Oh, you're right.

What are you two doing? Are you guys kids or what?

- All you do is goof around. - I'm not goofing around.

Listen, okay?

According to this, Ms. Doh and I are only three percent compatible.

But the compatibility between her and UDC is 97 percent.

She was meant to work at UDC,

and no wonder she and I never see eye to eye.

It accurately predicted the current situation.

What do you say? Doesn't it give you the chills?

Have some coffee before you get more fortune-telling readings done.

Thank you.

Here.

- Thank you. - No problem.

- Thank you. - No problem.

(Kim Young Han)

I found it! I figured it out.

What?

Mr. Ko, thanks so much.

Thank you! I found it!

- What? - What did he find?

I think he's possessed or something.

(Blocked Caller ID)

(I will give you evidence for the Baker case. Check locker 23)

- I have to step out too. - Ms. Doh.

What's the matter with everyone today?

Wait up.

- What did you find? - I need to verify it first.

- What about you? - I need to verify it first too.

Hello. Good day, guys.

- My apologies. - Gosh, you scared us.

(Locker Number)

Ms. Doh, the manager is outside now.

You have to be careful, okay?

(General Waste)

(Women's Change Room)

The women's change room.

(Locker Number)

You're hiding something, aren't you?

What do you mean?

I know...

that you're lying to me now.

You can't sleep because you have to earn money for your son's tuition.

There were dozens of instant coffee sachets in your locker.

(Kim Young Han)

Even the day we first met, you had already drank...

at least 3 or 4 of them.

You work two jobs at night, which must be exhausting,

so I'm sure you rely on coffee.

And that's why you've lost at least 10kg since the time...

you took the photo with your son before he went abroad a year ago.

How did I know your son is studying abroad?

Here.

All the streetlights in this photo have incandescent light bulbs.

Surprisingly, the Ivy League schools are slow to adopt new technology,

whereas most of the streetlights in Korea now use LED bulbs.

And these gloves. You probably brought them...

because you were in a rush to get to work after your night shift.

The various types of paint and adhesives including...

isocyanates on these gloves.

They can certainly cause asthma.

No, that's not true.

I'm certain that I developed the symptoms while working here.

That's why I filed a claim for occupational disease benefits.

It may take a while to show symptoms in case of occupational asthma.

That's why it can be confusing.

Well, I didn't intend to hide this from you.

My son is finishing up his last semester.

I couldn't tell him about working two jobs...

because he hates it when I take on part-time jobs.

You live alone, right?

You're making all these sacrifices for your son,

but he may not want that.

My son has no idea.

He can't know about any of this.

Well, sir.

Then what will happen to my claim?

Will I not get the benefits?

I'm not sure.

Nothing's easy. Life is so hard.

I'm sorry.

Don't...

apologize like that, please.

Mr. Kim, what is the matter with you?

You're never on time.

Just quit if you can't be punctual!

Dad.

Min Ki.

I'm okay, so you should go.

Go and study.

You hurt your back. You should take a day off.

I'm fine. You can go now.

Okay, I'll go.

Min Ki.

Buy yourself a treat.

Thank you.

- Goodnight, Ms. Suk. - Bye.

- Thank you. - Goodnight.

- Here you go. - Is this for me?

- Of course. - Thank you.

What is this?

Thank you.

Ms. Doh, listen to me carefully from now on.

If it's because of the paint from the factory he works at night,

in principle, he should request for an industrial accident.

Mr. Kim was fired from that factory too.

Still, he can request that it's an industrial accident.

Anyhow, we need to prove...

it's a furniture factory instead of a bakery.

If he requests again, it will take another three months, right?

We don't even know when this small business will close down.

Mr. Huh.

There's a limit to how much I can put up with this.

- As long as it's under my name... - Then...

let's do it under my name.

Do you think it's because I'm afraid of being responsible?

Calm down.

First of all, go to the factory where he works at night...

and check for substances that can cause asthma.

I already did.

The MDI rate that causes asthma was three times higher.

I went secretly and checked.

If I didn't, we'd be wasting time with the equipment. You know that.

Here.

If Mr. Kim reapplies from the furniture factory,

I'm certain it will be proved that this was work-related.

So just make sure these papers get passed.

It's going to be accepted anyway,

so let's not make him suffer for another three months.

If we found a substance, he should reapply according to the procedure.

He should wait for three months.

I knew it.

We need to look at cases involving occupational asthma...

that have been reported since 2010.

Among those cases, three of them have been confirmed...

that mental stress was the cause instead of a substance.

It's not a high probability, but there are actual precedents.

Are you claiming this is an asthma attack due to job stress?

It's too ambiguous. This won't be passed.

Seriously.

It will pass.

If you look at the medical reports,

Mr. Kim visited the hospital due to asthma mostly last January.

To be exact, he went every Monday afternoon.

Why? Because every Monday morning,

there was a staff meeting.

And the owner hosted that meeting himself since last January.

The cause-and-effect checks out.

What's surprising is...

this case of an asthma attack that resulted in death last year.

The owner hosted his so-called meeting...

and bullied him harshly to provoke his asthma.

But unfortunately, he ended up dying.

If we don't get to the bottom of this, someone else might die.

Do you have official data of that staff meeting?

Yes. It's saved on the Webmaster calendar.

So job stress is the common cause for the two asthma patients.

There's a 2012 thesis on the connection between...

stress and asthma attacks. I'll give it to you, so attach it.

Also, I'm the head researcher.

I'll take responsibility.

Thank you.

They found traces of melamine from the red sack.

It's a substance that shouldn't be in food.

Do you remember the milk powder incident from 10 years ago?

That melamine?

Ms. Gong said it's not our business and told me to drop it,

but I reported it to the Food and Drug Administration.

Their business will be suspended for at least three months.

Nice job.

(Thank you for your support all this time.)

- Did you hear news of the owner? - No.

The head baker called me and said he got arrested.

For installing a hidden camera.

Is this the Crime Team of Namil Police Station?

I have something to report.

(Letter of Resignation)

What is this? Are you getting married?

No. I can't stand the sight of you, so I quit.

So Young. You know how much I care for you, right?

Don't you know?

Why don't we talk over a glass of wine?

Let go of me, you crazy jerk.

Hey. Do you think I didn't know what you were up to?

You brat. Come here.

Hey!

I was nice to you because of your looks. Are you crazy?

- Who are you? - Stop this.

- You are under arrest... - What is this?

for violation of article 14 of the Sexual Violence Law.

- Hey. - You can hire an attorney...

and have the right to remain silent.

What on earth? Let go! Do you know who I am?

Stay still!

Go and rot in jail, you crazy pervert.

- Hey! - Shut up, you jerk.

- Come here. - Let go. I can walk on my own.

I feel sick. He was a total filthy pervert.

The company's financial affairs were a mess,

and he'll be charged with embezzlement and malpractice too.

Ms. Doh, good job.

Il Sun. I took care of the asthma case.

I need to do some last-minute checking,

so I'll drop by the site and go home.

I'll submit the report tomorrow. Salute!

You don't have to salute me.

Unity.

We need to unite as one now. Okay?

- Depending on how nice you are. - You punk...

Goodness.

I found it during last night's patrol.

I didn't know whose it was and checked it at home.

I think you should take a look at it yourself.

(I solemnly swear to keep all of the above strictly confidential.)

(Signature and Seal, Park Sung Joon)

They were arguing, and he was pushed.

Do you see this as murder?

This isn't murder.

I'm sure of it.

It's been leaked. UDC has it.

Darn it!

He had a muscle spasm. I'm sure of it.

He tried to save him at the last moment.

It wasn't an intended murder.

Could you zoom in?

He tried to save him and his hand...

A spasm!

You're right, he had a spasm.

But wait. Are you sure this video clip is credible?

Who was it? Did they drop it or just leave it?

Darn.

The hip-hop boy!

He's the one we were looking for.

He must've come to give me this video clip.

But he was acting weird.

He wasn't trying to harm me. He was only scared of TL.

Then he's in contact with them too?

- Probably. - Then why would he come to us?

Because of his conscience?

Ms. Gong, this video is sure evidence.

He had muscle spasms in his hands, which means it's not n-Hexane.

We were wrong.

Gosh...

Darn it, what do we do? We're going to be in trouble.

And we only opened up six months ago.

Let's start from the beginning.

How long has he been missing?

More than 10 days.

He could be dangerous.

If you're right, he's the living proof.

Fine. Let's open up all possibilities.

Find everything that can cause muscle spasms.

From heavy metals to any kind of crazy substances.

Gosh.

I guess you make mistakes too.

Fine.

Let's try this.

Forget about the current epidemiological survey.

- Could it be... - How did we miss that?

Myasthenia in the leg.

Chronic cough.

Skin lesions.

This...

must be mercury poisoning!

Ha Rang's mother must have witnessed the skin lesions on his body.

And I'm sure she remembers it.

It was the last she saw of her dead son.

And the skin lesions...

will tell us what caused the poisoning.

He would have had skin lesions somewhere around his chest.

Some red or swollen spots.

I know it must be hard, but please try to remember. It's important.

It looked similar to this.

It wasn't this bad, though.

This one?

How about this?

Yes.

They all looked like this.

Is this why Ha Rang passed out?

I'll tell you when we're sure of it, ma'am.

Okay.

Both Do Young and Ha Rang's hands were trembling.

That means they were exposed to it at the same time.

Then the place they could have been exposed to it at the same time...

Ms. Doh!

Hello.

We met at the funeral.

I'm Ha Rang's colleague.

Thank you for finding out about the n-Hexane.

No problem.

If I get sick on the job, I'll go and see you.

Of course, you won't get sick. Don't say that.

Hey!

I told you to take this.

I heard you live with your grandfather.

I packed some kimchi and side dishes,

so be sure to eat them.

You shouldn't have.

Thank you, ma'am.

I'll get going, then.

Take care.

Ha Rang...

always skipped meals when he lived in that dorm,

and he and Do Young couldn't eat square meals, either.

The dorm. A place the two of them shared.

I have to get going, ma'am.

Okay.

(Exhibit 16)

(Details)

(Location, 177-13, Nameun-dong, Namil City)

Joong Eun?

Over here.

Hey.

Namil...

is the place TL was planning a bio-industrial complex.

Gosh... Be careful.

Yes, ma'am.

Great.

This video is just a draft version of what we will be screening...

at the Bio World Convention in the U.S.

We will easily reach a preorder of 30,000 liters...

before the second factory is finished.

He even succeeded in landing a second client.

I was only there to make it final.

Mr. Choi was the one who pulled all the strings.

Is that so?

Mr. Choi played a big role.

It wouldn't have been possible if it weren't for the Planning Department.

Everyone is praising him to be the next king of management...

after you, sir.

It means he wants a bonus.

He's only giving me the credit because he's shy.

Of course not, sir.

- I'll be outside, sir. - Okay.

Watch out for the press.

Make sure to take care of them before anything come up.

Yes, sir.

I've made it the Planning Department's main duty.

Is Moh Sung Kuk helping you out?

I asked him to make sure not to cause us any damage.

I'm sure he'll do well.

If not, then he'll have to take responsibility.

I'm sure he'll do well.

I just hope he doesn't get caught trying to hide something again.

Or else it will cause great damage to the bio-industrial complex.

I won't let it slide if that happens.

It will be easier for him to deal with Joong Eun.

Since he has nothing to do with the kid.

He's an expert in that field.

Use your tools wisely.

He's a useful one.

Yes, sir.

Oh, and...

are you letting Seo Rin meet her mom behind my back?

That would never happen, sir.

Make sure it doesn't.

You better start putting her in your past, too.

I understand, sir.

Right.

Today is the day of Joong Eun's trial.

I'm sure it will end...

the way you wanted.

All right.

I'll get to work, then.

Hello.

What? What do you mean?

But you said we would win.

I did,

but they changed judges and that means they meddled with the court.

I mean, TL did.

But... No, that can't be true.

It's true. And I won't be able to handle it.

I think we will have to make a compromise.

If we're not careful,

you might be prohibited from seeing your child.

How could you say that as a lawyer?

Will I be likely to win if I appeal?

I'm sorry. I can't guarantee anything.

It seems like they've already planned everything out.

Then what if I don't do it?

If I decide not to appeal,

how much will I have to pay?

I'd say...

about 200,000 dollars in total.

(Doh Joong Eun)

(Choi Tae Young)

I heard Ms. Doh went to work again today.

So? Are you here to tell on her? I thought you were a busy man.

I'm getting a bad feeling.

You need to move one step ahead of her.

What do you mean?

Don't be so cryptic. I'm not following at all.

She can attack you anytime if her limbs are functioning.

You're letting her roam around freely.

You must've done a ton of bad deeds so far.

I did what was necessary.

Look, Mr. Moh.

What did you find at the site in Namil?

What are you hiding this time, you sneaky man?

About TL Oshem...

As you know, it's strictly confidential.

"Strictly confidential".

Are you confident that you can keep it confidential?

Yes, as long as you don't obstruct.

And if you can take care of Ms. Doh.

Why should I? You can do it yourself, can't you?

You're even giving orders to the CEO of the company now.

Is it about time you left the company?

Shall I fire you?

Fire me? You'll have to kill me.

From TL Mobile to Automotive, Display and Biotech,

I know about all the occupational diseases...

caused by hazardous substances,

which the company has been trying to conceal.

Just firing me won't do.

You shouldn't let me walk out of here alive.

Do you understand?

No, I don't.

Why bother reporting things to me if you have that much power?

Shall I handle things on my own?

- If that's easier for you... - It must be the chairman's order.

I know that much.

If you keep this up, you'll be taught a serious lesson someday.

My gosh, thank you for your concern.

And you're right.

All of this is what he wants.

That includes you and me locking horns like this.

You see,

I am simply following his orders.

It's me.

Look into how much UDC has found out about the site in Namil.

Thanks.

All the sacks that were left around the dormitory are gone now.

They were here a month ago.

Someone must've got rid of them since that time.

What was in the sacks?

Waste materials from the building next to it?

Or construction materials?

A company that makes industrial detergents...

was most recently registered under this address.

Did their industrial waste contain a toxic substance?

Then poisoning is possible.

If the toxic substance leaked into the dormitory...

I'm sure someone cleaned up the site to conceal the traces,

but it'd be difficult to keep it as a perfect crime.

I knew it.

The silver liquid with high surface tension.

It turns black when it comes in contact with powdered sulfur.

The toxic substance that caused...

the severe skin problems which shocked Ha Rang.

It's mercury.

If this heavy metal is spread all over this building,

I'm sure it leaked into the dormitory.

Is Doh Joong Eun still inside that waste building?

Yes, sir.

What about the dormitory? Did she go in there too?

No.

What about the evidence? Are you sure she found it?

- Yes, sir. - Get out of there. It's too late.

She could easily lose her footing and die here though.

What do you mean?

Let's get rid of her.

Answer quickly, sir.

If you don't answer, I'll consider it a yes.

Who are you? Identify yourself!

What kind of work do you do?

No one should be injured...

No one should get sick...

And no one should die on the job.

If you're ill, it is not your fault.

It's all because of your job.

Hello. I'm Gong Il Sun, the Chief of UDC.

Yes. We'll be right there.

- Let's go! - Let's go!

(UDC is on the move!)

- Move! Move it! - Let's go!

The Undiagnosed Disease Center was founded...

through a joint effort of the Ministry of Environment,

Ministry of Science and Technology, and the Ministry of Labor.

It is the only independent...

epidemiological investigation agency in the country.

Various misdiagnosed diseases from all over the country.

Does it hurt?

From undiagnosed diseases,

mysterious deaths,

and occupational diseases that haven't been discovered,

we will find out all the diseases that you suffer from,

just like detectives.

The camera's rolling.

- We, UDC will... - UDC will...

- always be on the laborers' side! - always be on the laborers' side!

(The laborers' true friend! Come to UDC!)

Take care of it.

If she found the evidence that we were trying so hard to hide,

hide it again.

Why does it have to be murder?

Kim Do Hyeong has been arrested for murder.

It isn't me!

We have to find the mercury as soon as possible.

I'll go to the site in Namil.

You sent her to that place again?

You guys are doctors!

Not detectives, but doctors!

Mr. Huh, your hunch was right.

You're truly amazing. Great job.

I think she's being sarcastic.

It was a down-right compliment.
