"UDC".
"Undiagnosed Disease Center".
What kind of place is this?
Let's say someone got sick while working.
They don't feel well, but they don't know the cause.
That's where we come in.
We go and look into the working environment.
How?
Cue!
Gosh, it's so dark.
- This is... - That isn't that important.
Any questions?
I heard UDC doctors can seize and search like the prosecution.
Is that true?
That's the most important part. It's the reason why UDC exists.
Think about it, if we can't seize and search,
how would the companies act?
"We can't make it an industrial accident. We'll be in trouble."
They'll do anything they can...
to back out and hide evidence.
If we show them the search warrant right there...
Peace.
Now, let's move on to the next location.
Excuse me, guys. So, this is the...
- I have to explain this! - Just come, already!
He wants to be the only cool guy.
This is the analysis center.
You can think of it as our National Forensic Service.
And this is the person in charge, Ms. Suk Jin Yi.
Hello.
The Namil mercury case is the most representative example.
Gosh, guys...
stop staring me.
I'm not a celebrity. I'm a doctor, just like you guys.
Right.
I'm Doctor Huh Min Ki,
the one who revealed the mercury exposure.
Mr. Huh. You have a patient.
Sure.
(Doctor Detective)
I hear a rale in your lungs.
- Are you out of breath? - Not really.
- All right. Please wait outside. - Okay.
Mr. Huh, your next patient...
Gosh, I'm starving.
What should I eat so that people will get jealous of me?
I'm exhausted.
They're ordering lunch boxes, Ms. Doh.
You should eat and get some rest.
I have something to finish up before lunchtime.
I'll take care of lunch on my own. What about Mr. Huh?
He's playing hooky, of course. I'll save your lunch box, then.
Thank you!
(Bacterial Lung Disease Study)
We have proved that it has no legal basis,
and we have also filed for an injunction...
to suspend their rights.
So I would appreciate it...
if you could share our countermeasures.
Thank you.
(TL Seoul Medical Center)
Is everything fine with you these days?
Yes, other than the colloquium preparations.
Why are you worried about me all of a sudden?
- Is anything wrong, Dad? - No, it's nothing.
You should really take care of yourself.
Leave everything to Tae Young.
All right.
Don't worry about me.
Why?
What was that about?
Tell me, Dad.
You know you can fool Tae Young, but not me.
Mr. Kwon, give us some privacy.
Yes, sir.
Did someone break into the VIP ward?
It's nothing to worry about.
Goodness, who could it be?
Nothing bad happened?
Of course not.
Who would dare try to harm me?
Who else knows? Besides me and Mr. Kwon.
That's it.
- What about Tae Young? - Min.
Don't tell anyone about this.
Do you understand?
Hey, I came to see Dad, and just called.
I see.
There's no other reason you called?
What's with you? You sound so cold today.
I'm busy. If you called to say hi, I'll hang up now.
I'm doing fine.
Okay. But...
Tae Young.
Aren't you curious about how Dad is doing?
Is there a reason for me to be curious?
No.
Get back to work then. Bye.
What was that about?
It's nothing.
Tae Young, will you really be okay?
To get involved with politicians.
Even after the mercury exposure case was revealed,
Mr. Moh got away with it like a sneaky little rat.
To stir up an issue again and hold him responsible,
this is the only way.
That's true, but...
I'm worried it might irritate the chairman.
Why is everyone so worried about the chairman today?
Sorry?
It's nothing.
First of all,
let's proceed as planned.
Okay.
Then I'll contact Congressman Kim...
of Environment and Labor Committee.
(Grandma's Kalguksu)
(50 Years of Tradition, Grandma's Kalguksu)
Goodness.
I have so many missed calls.
Hey, what's going on?
Wait. Hey!
Grandpa!
Oh, gosh, no!
No!
Grandpa!
Darn it, you scared me!
You almost killed me!
I'm sorry. I'm really sorry.
- Gosh. - Grandpa, are you hurt?
No, I'm fine. I'm not hurt.
Lady, shouldn't you be worried about us first?
Who are you people?
We're victims.
Don't you see this scratch on my shoe?
Do you know how much this costs?
- It's just a little smudge. - Hye Mi.
Hey.
Why don't we have a talk?
What do you want?
Not you guys.
Oh, my. You're badly hurt.
Doesn't it hurt?
I'm sorry. I lost control because the slope was steep.
Get up. You can go with me.
Let's get this treated first.
Hey, mister.
You should look at us first.
Can't you see this?
You sound rude.
I'll talk down to you too.
What? Okay, fine. I saw it.
Are you happy now?
Hey, mister.
You must not know what these shoes are.
These are from the Paris Collection...
Henry Smith's shoes that were introduced...
at the 2019 Paris Collection.
Only 40 pairs were made worldwide,
and just two pairs were imported to Korea.
As far as I know, those shoes cost 12,000 dollars.
Do you seriously think a pathetic guy like you...
can pull off the shoes?
You're really rude. Hey, mister...
Do you know what Henry Smith did after selling those shoes?
He donated all the money, you jerks.
Do you know why you guys look so stupid no matter what you wear?
It's because you guys are fake.
And you. You have chili pepper stuck between your teeth.
Let's go. Follow me.
Hey, mister. Who are you?
Me?
A doctor.
Sir, I'll carry that.
Oh, no. This is all damaged.
This palette.
Oh, yes. I bought it for her.
But it's broken.
Oh, I guess your granddaughter paints.
Are you good?
What? No, I'm just...
Let's go inside.
(Summons to Witness)
Sir, Mr. Moh of Oshem is here to see you.
Mr. Choi.
I heard the news.
You'll attend the parliamentary inspection of TL Metro?
Yes.
There's no reason to avoid it.
Until when do conglomerates have to avoid it like cowards?
I'll go and hear what they have to say...
and admit to things I did wrong and make amendments.
If necessary, I'll even cut out the rotten parts of this group.
Don't you agree, Mr. Moh?
With all due respect,
TL is not something you can just hand over.
TL and the politics have always shared a principle...
that they never meddle in each other's business.
Nothing has changed. That is...
the path a corporation should take.
The current situation is a total mess,
but you still seem lost in the wrong path.
The world is changing so rapidly.
Even if you don't like it,
you should at least pretend that you keep up with it.
I understand.
You can do what you like.
Yes, I'm Gong Il Sun of UDC.
Does the committee's position...
remain unchanged?
An injunction for suspension of UDC's rights has been filed.
It will be inevitable for UDC's rights to be reduced.
You should at least give me a proper explanation.
How could you just notify this unilaterally?
Who filed for the injunction?
It's TL, isn't it? Is TL behind all of this?
You'll soon be requested to attend a meeting soon.
- You should wait. - Hey...
- Ms. Gong. - Yes.
What was that about? Is something wrong?
No. Don't worry, it's nothing.
Is there a problem because of TL?
I would've already asked you if that was the case.
You don't have to mind.
Right, are you finished unpacking?
Yes.
There's nothing much to unpack.
Thank you for letting me stay here.
I'll work harder on my work here now.
I should be thanking you.
You won't be able to say you'll quit now.
Since this is your home.
About the medical malpractice case,
the truth will be revealed in the end.
Don't be discouraged.
I'm here for you.
Min Ki skipped work, but he brought a patient.
It serves him right!
He must be hungry. He must not have eaten yet.
What's wrong? You don't have an appetite?
No. I just had a heavy breakfast.
Where's Joong Eun?
I heard she had some urgent work to take care of.
Enjoy your meal.
Where are you going?
Mr. Huh.
Yes, thank you.
Let's begin.
Don't worry.
His arm has been scraped slightly,
but if he takes good care of it at home, it'll heal in no time.
Okay.
I'm really okay. Don't worry.
I'm not worried.
Can't you stop collecting waste paper now?
I'll disinfect the wound now. This may sting.
Okay.
You're very good at standing the pain.
If it were me, I'd be hopping around the place in pain.
It's all done.
(Dr. Huh Min Ki. Thank you.)
- Hye Mi. - Ms. Doh.
What brings you here?
You don't remember me, do you?
I saw you at Ha Rang's funeral.
We went to the same college.
- Goodbye. - You can come anytime
- if you need help. - Thank you.
- Thank you. - Wait.
Sir, this is a prescription.
Don't forget to take your medicine.
Thank you, Mr. Huh.
Thank you, Mr. Huh. I'm so grateful.
If it weren't for you, he could've been hurt badly.
No, it's...
I...
Hye Mi, I heard rumors that you're amazing at drawing.
Hye Mi is number one in drawing in her neighborhood.
- Way to go, Hye Mi! - That's not true.
He's right. You're number one in drawing.
Stop being silly.
- We'll get going then. - Okay, goodbye.
Hold on.
Here.
(Dr. Huh Min Ki. Thank you.)
It looks just like me.
You really are number one.
What are you talking about? This drawing looks way better.
Seriously, come on.
Hye Mi. Take good care of your health.
Okay. You don't have to worry about me, Ms. Doh.
If you get into trouble, you can always call me.
Okay.
Hye Mi, let's go. Thank you.
- Thank you. - Goodbye, sir. Bye!
Do I really look this handsome?
I said it looks way better.
I know.
I mean, the drawing looks better than you in person!
Grandpa, give it to me.
This is for the palette.
It was my fault for parking my car there.
Hye Mi, what are you doing? Come on.
Okay.
(TL Seoul Medical Center)
- Hey, you're here. - Yes.
I heard you asked for me urgently.
What is it about?
You must have a lot on your mind lately.
Why? Do you want to change the world?
If a businessman gets involved with those cons in politics,
his life will be ruined.
Don't you know how I've lived up until now?
Sir, you forgot to check your surroundings.
Oh, no. How could I make this kind of mistake?
I must be too old now. I couldn't even check my surroundings.
For goodness' sake.
Father. But still...
Tae Young.
You should never meet politicians...
except when you buy them drinks at night...
or bribe them.
Mr. Choi. Regarding the SL-5 issue,
why don't you go to China for a while?
I've taken care of the politicians.
Mr. Choi. Why don't you go abroad and take a few days off?
Our factory in the Czech Republic is almost complete.
You should check the progress there.
Why would I go abroad?
Do you think I didn't know?
How can you call yourself my son?
That you and your wife are conspiring...
to backstab me?
- Father... - It's been 60 years.
No matter how much the government and the world change,
this too shall pass by.
Don't give me trouble and just leave.
I can't stand the sight of you.
What are you doing standing there?
Can't you see us playing Go?
So do you mean the police want us to investigate?
(Detective Jun Joon Woo)
Our chief recommended it.
Since you're experts in this field,
and the chief thought it'd be hard to take care of it on our own.
We look forward to your cooperation.
Of course we'll cooperate.
But what is this case about?
It's a murder case. What does it have to do with us?
It's obvious this is a murder because of a love affair.
Mr. Ha, please.
They were a couple in their early 30s.
The girl was preparing for a civil service exam,
and the guy worked for a conglomerate.
After failing the exam,
they got into a big fight that night.
Everyone at their dorm heard it.
But the guy coughed blood that night and had trouble breathing.
The police think the girl poisoned him...
with a pesticide after having a big fight.
But why did the police ask for our help?
This isn't just because of love quarrel.
The woman stated...
that the guy handled poisonous substances at work...
and that's how he got exposed.
Il Sun, where did you say the guy worked?
A company that manufactures etchants for semiconductors.
They handle corrosive gas.
Then what did the guy say?
That's the problem.
His lungs are totally damaged,
and he's in a coma at the intensive care unit.
At TL...
Medical Center.
The guy's been unconscious since the day he fainted...
They found...
a deadly pesticide inside the cupboard of their dorm.
And the girl's fingerprints were all over there.
This case is interesting enough...
to be made into a documentary.
First of all, we must check for poisonous substances at his company.
Min Ki, go to TL Medical Center...
and talk to the pathologist.
Joong Eun, go to the prison and talk to the woman.
Mr. Ha, let's go to investigate the etchant factory together.
- Okay. - Let's move.
(TL Seoul Medical Center)
Thank you.
It's strange the patient coughed up blood.
Usually, pesticides don't cause hemoptysis.
He keeps showing the symptoms of pneumothorax.
Things don't add up.
I think it might be another type of poison.
We're suspecting that too.
There are many poisonous substances at his workplace.
This is the biopsy from his pneumothorax procedures,
and it seems like fibrosis is progressing quite rapidly.
You should do some cross-checking.
It seems like UDC is coming out really strong lately.
Well, I...
No, it's just...
We have so many talented doctors at our center.
Is Ms. Doh in charge of this case?
How did you know?
I guess this case will be solved in no time.
You two went to the same college?
We were just...
pretty close.
Have a good day.
(Photos from Crime Scene)
Then what about the pesticide found at your house?
I was going to use that to kill myself.
I used all the money I saved up...
and had no hope of living. So I decided to commit suicide.
But I got afraid and couldn't take it...
like a fool.
Now, I'm even being called a murderer.
It's true that we fought that night.
But that was really just a fight. I'm not lying.
I really didn't kill Joon Sung.
Please believe me.
Ma'am, I really didn't do it.
Ma'am, it wasn't me.
I really didn't do it.
Did you ever hear...
that Mr. Han handled poisonous substances...
at work?
No way. These pipes are all sealed shut.
There's no way it can be leaked. It's impossible.
It says here there was a pipe inspection the day before.
That has nothing to do with him being sick.
It's not like he did it alone.
There were three more workers besides Joon Sung.
But he's the only one who got sick. The others are perfectly fine.
They're working right now, so take a look.
Before the pipes are opened,
they use a nitrogen pump to get rid of all the toxic substances.
Throughout the history of our company,
there hasn't been a single exposure.
The employees finished the inspection safely.
But we can't rule out the possibility...
that the person who opened the pipe first...
got exposed momentarily.
Come on. What is the matter with you?
Look. These are the records of the direction of the wind.
This shows the change of wind of that day.
(Northwest)
On that day, the wind blew from this side to that side.
That means Joon Sung had his back against the wind.
Even if there was a gas leak, it would have gone...
to the person in front, not to Joon Sung.
And...
I don't want to admit this,
but his girlfriend...
fed him pesticide.
Hello, Ms. Gong?
Do you really think she fed him Gramoxone?
(Gramoxone is used as a herbicide, and it's known to be poisonous.)
It's too early to decide.
I'll be visiting the scene before returning to the office.
(Gangil Student Dormitory)
(Do Not Enter)
No!
Come on.
Come on!
You're going to get hurt!
Forget it. Let's end it, then.
- Why do you care? - Come on!
Han Joon Sung!
Joon Sung!
Are you all right?
(Evidence)
(Gramoxone)
(Photos from Crime Scene)
Why was he the only one who had symptoms?
That is the main point.
The company turned in...
the wind direction records of that day...
to claim that it isn't an industrial accident.
Joong Eun, what do you think?
If we look at the circumstances,
it does seem like a murder case.
But I'm doubtful.
About what?
I can't be sure yet.
I feel the same way.
It feels like we've missed something,
but I don't know what it is.
Any other opinions?
Go on.
At times like this,
instead of using our heads...
Please excuse me
Is it an industrial accident or not?
Oh, It's not!
We have to depend on the unknown...
Come on, I was talking.
Joong Eun, go back to the scene,
and Mr. Ha, share what we've found at the company.
I have to get some work done.
Where are you going?
Does the director want to see you again?
Yes. I'll go curry favor with him.
Will you be all right?
I've got used to getting scolded by higher-ups.
I think that'll help me live long.
I could work as the chief for at least 50 more years.
They say, "Being criticized makes you live long".
Finish everything up.
Yes, ma'am. See you.
Don't you think she's ignoring me on purpose?
How could she not see me when I was trying this hard?
And what was that?
Fifty years is a dictatorship.
What is this, the Yushin Constitution?
Who cares if it's 50 years?
Someone like her deserves 100 years.
You're such a kiss-up.
What can it be?
According to the wind direction records,
there's a low chance that the victim inhaled a toxic substance.
What have we missed?
No way.
It's better to stick to a sure assumption.
But isn't this leaving it up to luck?
It's called selection and focus.
It's important to decide...
whether it's a murder case or an industrial accident.
So how are we going to do that?
Come on, Jin Hak.
Stand over there.
We have to go with the saying, "Know the enemy and yourself."
We have to understand the victim's position.
Isn't that "Put yourself in another's shoe"?
So we have to "Win every..."
- Come on. - I'm sorry.
Just stand over there.
Now, look.
The wind is blowing. Okay?
The victim...
was where I am.
What are you doing? Do you need help?
Ms. Byun, be quiet.
Jin Hak, your hands.
Do I have to make the sound, too?
Okay, good.
Now,
I'm going to scatter the puzzle pieces to this case.
(Industrial Accident)
This is the most important part.
Unexpected circumstances like this.
(Industrial Accident)
What does it say there?
- "Industrial Accident". - Okay.
Now, we'll assume...
it's an industrial accident and begin reasoning.
Then what?
By the way, if the settings are on gentle, weak, and strong wind...
- That jerk. - We can't leave anything up to you.
Stop it, already. I feel like I'm going stupid.
Where are you going?
Mr. Huh?
Let's do that one more time.
