The Veil (검은 태양)

Do you want me to tell you what I did with them?

I used my own hands to slit open their necks.

Dong Wook and Kyung Seok were killed with a gun, not a knife.

They had a mastermind who controlled them from behind.

Is that Baek Mo Sa?

Baek Mo Sa.

You asked me why I didn't contact the NIS after that incident.

I called the number you gave me.

But a group of other people showed up at the rendezvous point.

They had come to kill me.

Do not trust anyone.

Don't ever.

My gosh. You're really tense.

Relax, will you?

Here's what you asked me to look into.

Shin Sang Hoon is with General Affairs.

He served with the UDU, the Navy Intelligence Unit,

and was a special hire.

Why is he with General Affairs now?

The project he was hired for got called off.

Now that they had no use for him,

no one wanted him on their team, so he ended up there.

Is there anything else?

There was one interesting fact.

Do you know who was in charge of the project he was hired for?

Chief Ha Dong Kyun.

I think there's a connection between the two,

but however hard I look, I can't find anything else.

And what's going on with Chief Ha?

What were you to scheming?

Did you really...

forget everything from the past year?

Do me another favor.

What is it?

Check the operating room server.

Last year in mid-March,

there was an incoming emergency call from Dandong.

Find out who the last person to receive the report on it was.

That's not hard at all.

It's urgent. Make it quick.

I will. I'll call you as soon as I find out.

I said it's urgent.

I thought we could eat together.

Search thoroughly.

Take your time and circle.

Take your time and circle.

Keep going.

Bring it further this way.

Sang Kyun.

You look worse than before.

Do you eat regularly?

- Yes. - I was at your place last week.

You didn't let me in when you were at home, right?

You can stop this now.

It makes me feel uncomfortable.

I have something for you.

I have enough money.

I was compensated for Dad's death.

Sang Kyun. I want you to...

Don't you think so too?

That my dad killed himself.

That's...

not something you can decide on so easily.

I'm still looking into it.

So if you wait a little longer...

Last night, I dreamed of him again.

He stood by my bed...

and looked down at me silently, then walked away.

I tried to call out to him, but I couldn't make a sound.

Even in my dream, I couldn't do a thing.

Do you know...

how that feels like?

I do know...

how that feels.

How would you know?

You haven't been through it.

Sang Kyun. I'm...

I shouldn't have believed you at all.

It has been a year and nothing has changed.

What will you do about my poor dad?

I can't leave him like this anymore. Now...

I will do something about it.

Sang Kyun.

Sang Kyun.

Oh, I forgot.

What's this?

It's an agent's laptop assigned to Technical Development.

It's connected to the network,

but there's no movement yet.

Track the IP address.

Check the operating room server.

Last year in mid-March, there was...

an incoming emergency call from Dandong.

Find out who the last person to receive the report on it was.

Gosh, he's impatient.

I'm checking right now.

Wait while I get what you need.

What's this? This can't be.

What is it? What's wrong?

There's no record of it.

What?

I think it's a cafe on Sillim Junction.

Move.

It's the back door. He's in the system already.

Files are leaving the main server.

Lock it. Close down the server.

What's going on?

What do you mean there's no record?

It doesn't say who took the call.

The data was deleted.

Just the call you talked about.

Shoot, I think something's wrong.

I'll call you back.

How could someone get through our firewall so easily?

Well...

The person came in through a back door they'd planted.

There was nothing we could do.

- A "back door"? - Yes.

To put it simply, someone created a back door in advance...

to gain easier access to our server.

Are you saying an insider was involved?

Yes.

They used an agent's laptop that was approved by the agency.

It's clear an insider was involved.

Then you just have to find out whose laptop was used.

We're looking into that right now and will get the result shortly.

What files were leaked?

We need to check to get the details,

but they targeted top-secret intel...

assigned one year ago.

The hacker had complete knowledge of our server directory,

Excuse me.

Yes, what is it?

Okay, I got it.

What is it?

We found out who's laptop it is.

Whose is it?

Well, it's...

Director Choi Il Lak's.

Who's that?

Who is it?

He worked at Technical Development.

He was in charge of the MPK program.

How can a specific part be erased?

Someone got in the operating room and erased the record.

That's the only way.

Can you find out who?

I tried to find out.

But our server went down since yesterday's hacking incident.

- Hacking incident? - You haven't heard?

Someone hacked into our main server yesterday.

I heard only top-secret intel from a year ago was taken.

Was any of it...

from Foreign Intelligence...

gathered while I was missing a year ago included?

I don't know.

Anyway, everyone's under inspection because of the incident.

We should lay low and don't contact each other for a while.

I'm getting another call. I should get going.

You do know Director Choi Il Lak, right?

What? You worked with him before, didn't you?

Yes, ma'am. But why do you ask?

They found out the laptop used to hack our server was his.

And the hacker targeted the intel from a year ago.

Do you know what this means?

Do you think that's what the hacker wanted?

I'm sure the hacker wanted the file for the civilian inspection case.

In order to cover that up,

we had to pay a great price.

If Deputy Commissioner Do gets the information,

you do know what will happen, right?

No need to worry.

We will fully mobilize information from branches all over the country.

But it's not like...

we're the only one who's being chased.

I'm sure she's being torn by anxiety too.

What do you mean?

Do you think it only includes data that'll be used against us?

The civilian inspection case is the Achilles' heel...

of Domestic Intelligence.

If we can secure the data, we can take the initiative.

The situation isn't exactly going in our favor.

If things go wrong, it could backfire.

The leaked intel includes...

the information we can never let them have.

It'll end only when one of us fails.

That means we have to secure the intel first...

no matter what.

So I was thinking...

perhaps you won't have to step up to the plate for this.

I don't understand.

You can work behind the scenes to support us.

Then who's going to be in charge?

Someone who's not related...

to the civilian inspection case.

That way, if things go wrong,

we can get rid of the person in charge without any trouble.

Do we even have anyone for the job?

Come in.

Did you want to see me?
