Original subtitles

You and me, the old team.

The Kremlin's trying to find out who your assets are.

Somebody has been talking to the Russians.

Stick my life it's not you, Harry,

but you've got a mole in your organization.

- Sugar Horse. - Sugar Horse.

The best kept secret we ever had.

Who at 5 knows?

Hugo Prince, Richard Dolby, and me.

Lucas?

- Harry. - Look in your bedside drawer.

I'm being set up.

We've got a mole in Section D.

I need you to meet a contact in Moscow.

I'm on my way.

I'm sorry, Lucas.

Pearce.

Sorry for the late night call, Harry,

but I need to brief you on something

that can't wait till morning.

Are you alone?

- Yes. - Good.

Have you heard of a Polish village called Walily-Stacja?

It's five miles from the old Soviet border

and the Americans have decided it's the perfect spot

for their missile defense shield.

When the news breaks, they'll go ballistic.

Literally for all we know.

We have no choice.

I've just seen the latest US intelligence

on a Syrian Nuclear Weapons program.

The missile defense shield could be the only thing

between us and an airborne strike.

If the situation escalates,

I need to know your assets are in place

and that none of your Russian networks

have been compromised.

I need to know that you still have Sugar Horse.

Is Sugar Horse secure?

I can assure you...

I can assure you our position is just as strong

as it ever was.

Thank you, Harry.

There were angry scenes in Moscow this morning

as Russian leaders reacted to the announcement of US plans

to place missile defense bases in Eastern Poland.

One senior minister called it the greatest act of aggression

since the end of the Cold War.

Meanwhile, the Prime Minister backed the White House's

statement that the US plans are purely defensive,

aimed to offer protection from rogue states.

The Prime Minister also paid tribute to Alexander Borkhovin,

the Russian foreign minister who died overnight

following his collapse yesterday

from a suspected heart attack.

Would you like to explain why your technicians

are fixing a mobile listening device to our wall

while we are trying to deal

with a major diplomatic flare-up?

The short answer is that I suspect your boss

of the most serious betrayal

in the history of this organization.

Harry is being investigated under suspicion

of being an FSB mole.

- That's impossible. - That is entirely possible!

And in his absence, I'm taking control of this section.

I expect all officers to observe protocol,

you work as normal, and you report directly to me.

And while we continue investigations,

all your communications will be recorded

and analyzed by internal security.

This team is utterly loyal to Harry Pearce.

You cannot expect them to hear that information

and carry on as if nothing's happened.

I do not believe that Alexander Borkhovin

died of a heart attack.

I think the Russians are up to something

and until you find out what it is,

and how it relates to this crisis,

I don't want to hear another word.

Harry's been arrested.

Do they have any evidence against him?

I very much doubt it.

We'll be kept under surveillance,

our orders are to carry on work as normal

but to report to Richard Dolby.

That's ridiculous.

Whatever we may feel,

we need to work out what the Russian's next move is

before they know it themselves.

We start by finding out if that man's death

has anything to do with this.

Malcolm, get everything you can from the hospital

and Borkhovin's office.

Ben, get into the archive.

Get every document we have on Borkhovin.

Connie, tell me what the chatter is,

what the local media is saying.

Jo, I want his phone and email records.

I want to know everything he said, wrote and thought

in the last month.

And full cooperation with MI-6 on this one, everyone.

They'll be getting it from (indistinct) too,

and their contacts will be invaluable to us.

And where's Lucas, is he in trouble too?

I have no idea.

But if anyone hears from Lucas,

they let me know immediately.

Right.

I believe that Harry Pearce

has been passing secrets to the FSB.

- Are you sure? - I've sent you a dossier.

It should be with you now.

I think you'll agree the evidence is irrefutable.

But this goes back years.

I spoke to him last night.

I told him exactly what our position was.

We're meant to be briefing the CIA at 12:30.

I'm sorry sir,

I acted as soon as I received the intelligence.

I'm now doing everything that I can to isolate him,

identify, and pull back his assets.

And the least we can do is debrief them

and get whatever information they have on the Russian plans.

I can't believe Harry Pearce is a traitor.

There must be some other explanation.

Richard.

You've betrayed Sugar Horse to the Russians.

You must know I would never do such a thing.

Alexander Borkhovin is dead.

The Russians claim he had a heart attack.

What really happened to him?

I know as little as you do.

Only three people knew Borkhovin was a Sugar Horse asset.

Me, you, and Hugo Prince.

I have done nothing except protect

and cultivate Borkhovin for our use.

That dossier was faked, probably by Bernard Qualtrough.

It's part of the same attempt to attack Sugar Horse

just at the point we need it most.

Look Harry, I want the names of all the Sugar Horse assets

that you passed to the FSB.

Can't you see you're being manipulated

into demanding my names because they know

once they go into circulation,

the FSB will be able to get their hands on them.

Give me the names of your assets.

You've already made your betrayal.

You've already destroyed the network.

If you have a shred of humanity,

you'll let me pull out your assets with my own

and debrief whatever intelligence we can from them.

Sugar Horse is our only insurance

against a resurgent Russia!

If things escalate over the missile shield,

the fact that my network is still in place,

may be our only hope.

I think you know Charles Grady.

At least you're familiar with his work.

I want those names.

So, perhaps you'll give me a different response.

Betrayal is a lonely business, isn't it Harry?

I wouldn't know.

That secret feeling of power fades so quickly.

And the only thing that can bring it back is more betrayal.

The irony is, that each betrayal can only lead deeper

into the loneliness you were trying to escape from

in the first place.

I'm here to help you,

to release you from your loneliness.

The only help I need is in apprehending Bernard Qualtrough

and working out how he framed me.

I did make some inquiries

after you mentioned him earlier.

I learned Bernard Qualtrough has been a permanent resident

of Bangkok for the last 12 years.

Apparently, he loves the climate.

Either way, he hasn't set foot in the UK since 1996.

No, he's in this country now.

He's in this country because he forged this dossier

you've been reading!

Give me the names of your assets, Harry,

and this can all be over very quickly.

You'll have to go to his bookshop.

- There is no bookshop. - It's in Greenwich.

- The names, Harry. - Listen to me!

I can't give you the names.

If I give you the names, it will destroy the network.

It will just lead the FSB straight to them!

Hello?

Where's Ros?

I'm afraid she's with the in-laws.

They're rather taken up residence.

Where are you, Lucas?

Lucas, where are you?

I'm on a little antiques-buying jaunt.

Would you like me to get you some assistance

to get all the purchases back?

No.

I'll be fine. Bye.

How do you feel now?

Do you feel the urge to talk to me?

Do you feel the urge to talk to me about those names?

All right, well, we can start off by talking

about something else if you'd like.

We can start off by talking about your son.

My son has nothing to do with this.

Doesn't he? What about your wife?

My ex-wife has nothing to do with this.

- My... - Daddy!

My family...

Daddy, help me! Daddy!

Have nothing to do with my work.

- Daddy! - Of course, that's right.

Given that your work is your life,

that's meant that your family

has had nothing to do with you.

I had to keep them apart.

Daddy!

Do you mean it was convenient to create a veil of secrecy

and lies that they could never penetrate?

Had to protect them.

And what protection you gave.

That kind of protection

that meant that you would never be available,

you would never be there,

you would always be more involved with things

that were more important to you.

The kind of protection that meant that you betrayed

every single ideal and demand they had of you

as a husband and a father!

Daddy! Help me!

Daddy!

You're right.

Betrayal is a pathology, Harry.

Just like your son's drug addiction,

just like your wife's depression,

there are symptoms, huh?

Failed relationship, a tendency to anger quickly,

a preference for heavy alcohol consumption.

You're describing half the people

in this organization.

I'm describing a profile that many people

share features with,

but for which you provide the perfect match.

Give me those names, Harry.

Give me the names of all the assets you have betrayed.

You know you want to do it.

You know you want to tell me.

I want to reassure the Home Secretary.

Harry, you're never going to see the Home Secretary!

You're never gonna see anyone ever again,

unless you give me those names!

According to this, he was given a full post-mortem

following the heart attack.

The pathologist had questions but nothing to go on.

He had no idea that Paturi had been in Russia

six weeks before.

What's going on?

We think we have a lead

on what really happened to Borkhovin.

Good, because I've just heard from the Home Secretary,

he's on his way, so we have less than 20 minutes

to work out what the hell he can tell the Americans

about what Moscow are going to do next.

Adenosine triphosphate, found at four times

the normal level in Chandra Paturi's bloodstream.

Why didn't anybody pick up on this at the time?

Because adenosine is a naturally occurring substance.

It may look suspicious,

but there's any number of reasons

why a person might have raised levels.

So, the Russians are lying, they did kill Borkhovin.

- You need to see this. - What have you got?

Alexander Borkhovin used to get a lot of interest.

This file was signed out 25 times between 1919 and 2003,

every time by a man named Hugo Prince.

There's something else you should see.

It's a Russian news agency I'd never heard of.

It's just released this image from Borkhovin's postmortem.

Well, why would they do that?

It's a way of the government leaking information

they want people to know unofficially.

What's that mark on his shoulder?

Can you go in closer?

Closer still?

What the hell is that?

Borkhovin was a Sugar Horse asset.

At this stage, I think I should tell you

that Harry briefed me about Sugar Horse.

He was trying to save the operation.

By telling unauthorized personnel about its existence?

Whoever leaked that image is sending us a message

that they're onto our network.

If Harry was a mole, why would he expose himself like that?

Because the damage is already done.

He's already leaked the names.

When Hugo died, Harry and I split his assets.

We never knew each other's, but we both knew Hugo's.

Now an asset Harry took on has been murdered

just when we might have needed him.

That doesn't mean that Harry's responsible.

Someone could have got to the names through Hugo Prince.

I worked under Hugo for 20 years.

I knew him as well as I knew my own family.

He was not a traitor.

If you care to look at it, I have proof of who was.

Anyone can fake a dossier.

Lucas North never arrived, caught up in traffic?

Wherever he is, I know he's not a double agent.

I debriefed him with Harry.

Then I think you were party to a piece of theater

performed by two traitors for your benefit.

The first Sugar Horse asset has been murdered,

soon others will be too.

By the time the US and Russia sit down to thrash this out,

our intelligence on Russia will be a joke.

Unless you can force Harry into giving up his names

before they're killed.

You want me to use Harry's team

to prove that he's a traitor?

I want you to salvage what little remains

of British nuclear intelligence on Russia

before it's too late.

That's strange, I'm picking up an unusual telecoms

interference pattern on my own monitors.

It's as though someone on this floor

is using a phone scrambler.

That's possible, isn't it?

Not one I don't recognize.

Can we help you, sir?

I'd like to speak with Richard Dolby.

I'm here, Home Secretary.

I've just had a call from MI6.

A second Russian official has been found dead.

Her name was Maria Korachevsky,

she was a senior civil servant in Russia's nuclear program.

Was she a Hugo Prince asset?

I hope you all realize how this makes us look.

The Americans were counting on us to help push through

the single most important defense project

of the 21st century.

This was the chance to punch our weight

in the Atlantic alliance,

to prove what Britain brought to the table.

Sir, if you want us to work out what's going on

and do something about it,

I believe the team would be more effective

if they were granted full authorization

to the relevant information.

No, you're all tainted by your association

with Harry Pearce.

The Russians and their friends

were clearly far readier than we expected.

Without good intelligence,

we will never outmaneuver them on this.

And I've got less than three hours

before I have to tell the White House

everything we know to help them.

Sir.

Okay, if we're gonna continue,

there are things you deserve to know.

Dolby doesn't want you to know this,

but both Alexander Borkhovin and Maria Korachevsky

were MI-5 assets.

They were part of a sleeper network called Sugar Horse.

Sugar Horse was designed to keep Russian nuclear capability

under NATO control.

That network is now being destroyed

just as Russia plans to turn the missile defense issue

into a global crisis and restack the decks in its favor.

So unless we can find out who betrayed the Sugar Horse names

and stop them before anyone else dies,

we stand to lose any edge we ever had over Russia

and any protection against any future attack.

Why don't you just give us a list of names

so we can pull them out and debrief them?

The network was designed to be unbreakable.

Only certain names are known to certain individuals,

no one has the full list.

- But Hugo Prince is a link? - Yeah.

Hugo Prince and I were lovers.

I know he wasn't a traitor.

I'm not suggesting he was,

but when I saw how many times he'd signed out the file,

I had a look at what we had on him.

And the last time he requested the file

was September 23rd, 2003.

Well, according to his service biog,

Hugo Prince died on September 22nd.

So, someone accessed his file using his name

the day after he died?

Somebody who could be our traitor.

Okay, Ben, get back down to the archives,

see if you can find the authorization slip

used to access the file and get it to Malcolm

to put it through graphology.

Okay.

And the needle and the haystack stuff, I'll go with you.

No Connie, I need you up here,

there'll be an avalanche of chatter

once that second death's been announced,

and I need you listening in trying to find out

who the Russians might hit next.

Jo, you and I are gonna go through every Russian official

who's ever made contact with MI-5.

No one can give us the Sugar Horse names,

so we'll bloody well will have to work it out ourselves.

You realize all this could just prove

that Harry is the mole?

Yep, but it's also our only chance to prove that he's not.

You've got lots of liars on your team, Harry.

Do you know why?

Because you understand them.

Because you're the biggest liar of all.

King liar.

This is your damn run, Harry.

Isn't that so, Harry?

There's someone else

who knows about Sugar Horse, Sugar Horse, Sugar Horse...

- You okay? - Got a couple of leads.

Russian scientists keeps being mentioned.

Think I might check out what's going on downstairs.

Okay, but I'll need you back on the wires

as soon as possible.

Don't worry, I'll be quick.

And would you buy a pretty girl a glass of champagne?

Not today.

My name is Katerina, and I love champagne.

It makes me do very naughty things.

I'm sure it does.

The man in the leather jacket is FSB.

They're looking for you, everywhere.

How the hell do they know I'm here?

I have no idea.

But I saw him call for back up,

and they will be here in ten minutes.

Now, pretend to be a tourist,

happy to be with a sexy Russian girl.

Very good.

The things you need are in a package in the kitchen.

How will I find it?

The package will be in one of the drawers,

the third one down.

There's also a way out,

to an alley that leads back to the street,

so leave that way.

And go quickly.

Yes? Who is this?

- Hello? - Ben.

Connie is the mole.

She is the Russian mole!

I have photographic proof!

Lucas?

Getting short of time.

Ros thought you might need some help.

Okay?

Yeah.

Sure, search away.

- What's up? - Nothing.

I just...

I feel like my eyes are about to pack in.

Why don't you take a short break?

I'll make us both a cup of tea.

No, you're all right.

You go, I'm fine here.

Okay. No tea.

You're very young.

Too young to be wasting your life with this nonsense.

It's my duty, I don't mind.

It's all right. It's okay.

It'll be over soon. It's okay.

You've not given me any names, Harry.

Hard interrogation is singularly ineffective

against those with nothing to hide.

You know what they've already worked out on your floor?

That Borkhovin was murdered.

You ordered it, didn't you?

As a first step to dismantling the network

the West depends upon to neutralize Russia.

- I did not order it. - Come on, Harry.

It was only you and Richard Dolby who knew he was an asset.

It doesn't matter how much you lie.

Your own team is already piecing it together.

Now you know how smart they are,

you know how quickly they'll get to the truth.

I'll tell you something else,

they want to nail you even more than I do

because of the way you've betrayed us.

- Privyet. - Something's happened.

I need to get out now.

You must hold your nerve.

All we need is Harry's list of assets,

and the Sugar Horse network will return to dust.

He won't be able to resist much longer.

- Do svidaniya, Bernard. - Do svidaniya.

- Anything? - No, nothing.

You didn't bring Ben back with you?

No, he's still plugging away.

Probably will be for a while.

What is it?

I've learned something that might interest you.

I know Lucas North is in Moscow.

- What's he doing there? - I'm not sure.

Ros Myers knows he's there.

She's not telling you

'cause she expects him to make contact.

They're playing a very complex game.

If you want to find out what they're up to,

you better catch them in the act.

And how can I do that?

Well, I think I need to hear

what's on that listening device.

I was just with Ben Kaplan.

He got a call from outside, I'm convinced it was Lucas.

Richard, you and I have worked together

for more than 30 years.

Unless you find out what Harry's team is up to,

everything that you and Hugo worked for is at stake.

You don't want them to destroy that.

I'll take you to the Listening Suite.

No, you stay here.

You keep an eye on them, I'll go.

I'll tell you what I find.

Right. This code will open the sound files.

Has anyone heard from Ben?

- No. - No.

I'm gonna go down and check on him.

Ben?

Home Secretary.

I apologize for being out of contact today,

a little local misunderstanding has arisen.

I've seen the dossier, Harry.

The dossier, it's a forgery.

There's not a single word of it's true.

The world is on the edge of an abyss.

The Americans will do everything

to complete their missile defense program

and the Russians will do everything to stop it.

The ace up our sleeve was Sugar Horse.

It still is.

I've been through the dossier with Richard Dolby.

Alexander Borkhovin is mentioned.

Maria Korachevsky is mentioned.

All your communication with the FSB is documented.

Sir, you have to understand,

this is an orchestrated attack on me and my network,

a network that still protects us

and will still allow us to call Russia's bluff.

It's time for you to give up those names.

Home Secretary, I would never betray this country,

you know that.

I have given my life.

I have given everything I have in its service.

And you were very good, Harry.

I trusted you completely.

And I'll never forgive you

for the damage your actions have inflicted.

So,

when this is over, you will be stripped of everything.

Do you understand?

The Knighthood, the pension.

You will die in the most obscure and impoverished ignominy

that we are capable of heaping on anyone.

The only thing you can possibly salvage

is your self-respect.

So, if you have an atom of that left,

you will give us those names.

At the very least, we can save those involved,

and make this a fair fight with Russia.

Goodbye, Harry.

Let's go home.

Before I give you anything, I want to speak to Ros Myers.

I want my team to know why I acted the way I did.

The door's locked, he's not answering his phone.

I've called security.

I know he had an external call.

Tap into the phone monitoring device.

And when did you last see Mr. Borkhovin?

Were you surprised

when you heard the news?

Yes, I was.

The call was from Moscow!

Right, the sound file's protected by a six digit code.

It's meant to be randomly generated,

but I've installed enough of these things to know

that anything authorized by Dolby starts with a 27.

Come on, come on.

- He mentioned he felt unwell? - No, not at all.

Bingo.

Now, according to my monitors,

Ben received his call roughly 13 minutes ago.

Ben, Connie is the mole.

She is the Russian mole.

I've got photographic proof!

File deleted.

There's nothing. It's been deleted.

Weird.

So where the hell is Ben?

I've just spoken to Charles Grady.

Harry would like to see you.

Hello, Ros.

Can you at least give him a glass of water?

I'm afraid not.

None of this is true, is it?

I'm afraid it is.

I betrayed you and the entire team.

I gave the names of my Sugar Horse assets to the FSB.

I can understand how you must feel but in mitigation,

my priority has been the renaissance,

renaissance of something I believe in, profoundly.

I'm very sorry, Ros.

Can you let me out now?

Ros, how was Harry?

Did he say anything?

"Renaissance." Come.

Pull up everything you can

relating to the code name "Renaissance."

"Renaissance," it's a retired operation

run by Harry during the 1980s.

Its object was to persuade the KGB

that they had a mole inside MI-5.

Who was the officer used to dupe them?

Connie James, traitor.

Ilya Silvashko.

The under secretary for arms procurement?

Grisha Zormanov, Porto Blok.

The Kremlin's head of Internal Security.

Even I never thought Sugar Horse could have corrupted him.

But don't worry, he'll soon find out

his part and all this is over.

What about me?

When you reach Moscow,

you can expect the full gratitude of the motherland.

Thanks to you,

Russia can finally fulfill its destiny

to stop and turn back

the spread of American imperialism.

It doesn't matter what you try.

I've got the names of Harry's assets

and I've already passed them on to a trustworthy officer.

Within 20 minutes,

they'll all be on their way to tell us what they know.

You are a fool!

I know why Harry wanted to see me.

Connie James was turned during Operation Renaissance.

Security's just called.

One of the locks to the paper archive's been tampered with.

I can't wait for the car, I need to get out of here.

Get the driver to leave the ID in locker 416.

I'll contact you when I get out through airport security.

Step away from the Pods.

Is anything wrong?

Operation Renaissance.

That's where they turned you, isn't it?

You and Harry working to persuade the Russians

they had a mole.

He came back from Moscow the same,

you didn't.

You realize it's too late, I've already sent the names.

Not the right names, I'm afraid.

Names I gave to Richard,

because I knew you'd be working hard

to get him to trust you.

- Almost made it. - Almost.

Why, why did you do it?

I don't have to explain my actions.

Yes, you do, to me.

Did what I thought was right.

We're a pathetic little country,

putting a fig-leaf of British democracy

over the actions of a monster.

- What about Ben? - I had no choice.

- You had a choice! - Jo!

Connie, he was worth more than that.

Get her out of my sight.

I'm sure we'll see each other again.

I sincerely hope not.

Harry Pearce, Home Secretary.

And what will happen to the names you gave?

After all, they were real people.

The FSB will have killed them by now.

But we can surely expect the Russians to up the ante again

once they realize what we've done.

Without a shadow of a doubt.

Home Secretary, I'd like to talk to you about Ben Kaplan.

Although obviously Ben cannot be buried

with military honors,

the Home Secretary has agreed

he should be made a posthumous member of the DSO,

in recognition of everything he's contributed to MI-5

both today and in the past.

The real memorial for Ben is not in medals and ceremonies,

but in the way we carry on with our work

to make sure that their sacrifice was not in vain.

I'll be speaking to Ben's family later today.

If it's all right, sir, I'd like to do that.

Tell 'em they can call me at any time.

I'm assuming none of this makes any difference

to immediate American plans on missile defense?

None whatsoever.

We remain at a state of heightened alert,

ready for imminent Russian reprisals.

Then we need to deal with this.

Using your password, we were reassuring Sugar Horse assets.

One of them sent this back.

"Beware, Tiresias wakes 3PM tomorrow."

What the hell is Tiresias?
