Original subtitles

In the wake of yesterday's aborted terror plot,

opposition leaders have been swift

to question the government

on the impact of its anti terror legislation.

Other than a brief statement

in which it gave thanks to the police

and emergency services for their part

in averting an unthinkable catastrophe,

the government has yet to officially comment.

No details have been released about the identities

of the suspected terrorists involved.

It is believed

one of the would be bombers died in the attack.

There were no other casualties.

And finally-

- So you're not going home? - They sold my house.

Given that I was inconveniently dead.

It's a house.

I know that you and Adam were-

Adam and I were never gonna be Harry.

That's why I stayed dead in the first place

to let him move on.

- And you? - Me too.

To let me move on.

Adam was gonna die Harry.

To know him at all was to know that he knew

it didn't frighten him, it exhilarated him.

It gave him purpose.

Yes.

I've had a lot of time

and I've done a lot of thinking Harry. I made my choices.

I made them a long time ago and as it turns out,

they were the right ones.

This is what I am.

I want it back.

Give me section D.

Ros there's nobody more capable

of running the section, I know that.

You think because Adam died I'm gonna go to pieces,

well I'm not, I'm ready.

You might be.

You might be ready to leap into the fray Ros

but I'm not even sure

I can trust my own judgment at the moment.

My friend is dead and I want nothing more than revenge.

I want to take the Russian operation in Britain,

shoot it through the heart and watch it bleed to death.

Might be allowed that indulgence.

I'm going to ask Dolby for authorization

to target Kachimov directly.

Go to bed Harry.

We're not doing each other any good.

Just let me see that I have you alright.

Your contention is that the Kremlin

is sponsoring Al-Qaeda in London, yes?

By sponsoring terrorism on these shores,

Russia is demonstrating the price

Britain is paying for her wars in Iraq and Afghanistan

and thereby for her reliance upon Middle Eastern oil.

Rather than one supposes the cuddly Russian variety.

The Kremlin is attempting to destabilize this country,

which is a stepping stone on Russia's path

towards becoming the world's first energy superpower.

Moved as I am by the clarion call.

I'm bound to say that you haven't given me enough

to authorize the targeting of a senior Russian figure.

Especially since the relationship between Britain

and the Kremlin is already at a 30 year low.

The security service doesn't base its strategic policy

on one officer's desire for revenge,

however eminent the officer.

You do see that Sir Harry?

How's the promotion looking Richard? Rosy is it?

We're all upset Harry, but let's not forget ourselves.

After all these years it would be a pity

if either of us said anything we might later regret.

Just let's be clear Harry.

You stay away from our Arkady Kachimov.

Let's leave it there I think, don't you?

Good to see you.

Now the incident with the troll is unfortunate,

but everyone seems to have accepted it as accident

and they have no idea of the storm that's coming.

I have not been authorized

to target the Russian operation in London.

So what do we do?

We target the Russian operation in London

led by this man, Arkady Kachimov.

I've been told we can't target him directly,

but we have to find out what his game is.

He's a real and present danger to the British people.

And let's not forget this is the man

responsible for the death of Adam Carter.

Adam once said to me, revenge is an expression of pain.

Pain is weakness.

We never show weakness.

Well Adam's dead Jo.

Exactly how well do we know Kachimov?

File three inches thick, tells us where he is been,

what he's done and with whom.

But I want the smell of him, his breath, his sweat.

Until that end, I'll be contacting Lucas North

to brief me later today.

In addition to building a file on Kachimov,

we select a key Russian player in London.

No one with diplomatic status.

We don't wanna give them any reason to play the victim.

And then let's leverage that asset

until (indistinct) squeak.

Find me a way to stop Arkady Kachimov.

One more thing.

As of today, Ros assumes the position of section chief.

So, shall we?

Mama, mama.

Mama.

Yes, thank you.

Good morning Lucas.

Harry, how are you?

How's the team coping?

Would you mind coming onto the grid?

I need you to brief us about Kachimov.

Over there in two minutes.

Sorry.

Doug.

Harry Pearce has called me onto the grid.

He wants to talk about you.

You know pleased as I am to hear from you Lucas,

you're standing orders

to make direct contact with me.

This is what handlers are for.

Well I've yet to make my hands Arkadian...

This is a one use phone.

What will you tell him?

That you're a pussy cat.

You need to watch your back.

Harry's developed a particular animus for you.

He's jealous.

What is for your loyalty he has to, he's a spy.

And still this need to worry, it wounds him.

He wants to trust you.

He urges to trust you.

Therefore, in his heart he has decided to trust you.

Whether he is aware of that fact or not.

Gotta feel sorry for the poor bastard.

I promise I will try.

You know given the chance he's gonna eat you alive.

No, let us hope if he ever gets a chance

he has a hearty appetite.

And there can be no more direct contact Lucas.

We don't see each other.

We don't speak to each other again, no?

This is the nature of your life now.

You must live as though your friends are your enemies,

your enemies are your friends.

I must ask you to do this for me.

My operation will make contact very shortly.

Over and out then.

Over and out.

Do (indistinct) Malcolm.

Oh the chocolate one, sorry.

So how are you?

About Adam?

Well to be honest, I'm not quite sure.

That's a shock losing someone like that.

Someone that shines brightly in your life

and then winks out.

Adam was very admirable.

Drove like a lunatic there.

How are things with you?

Fine, I think.

Are you all right for food?

The service could arrange something so you're stocked up.

You're a very kind man Malcolm,

that's one thing that hasn't changed

but I don't mind shopping.

Lucas, if you would.

If you wanna get inside the head of Arkady Kachimov

the first thing you need to know is he's patient.

He spent years interrogating me.

He was always very gentle,

very playful, no aggression, no impatience.

So he's a chess player.

Yeah.

It was three years before he even began to seed hints

about turning me, sending me home.

And how did he approach that?

Did he play on sexual anxiety?

For fear your ex might-

No.

No he never took that route.

He used my relationship with you Harry.

In what way?

Well he implied that you personally didn't seem to be

in much of a hurry to get me back.

So however obliquely he used personal revenge as a motive.

Yes.

And what are your personal feelings towards him?

What do you want me to say?

I spent eight years getting to know the man.

He was good company.

He was my only company so.

Your only company?

You had no other visitors?

No FSB interrogators?

Plenty, especially in the first few months,

but I wouldn't describe them as company.

Thank you Lucas, you're free to go.

Good luck with the unpacking.

Ros, could I just have a word with Harry please?

Naturally.

I know what you're going to say and I'd like to say-

I wanna come back.

- No. - I'm ready.

You are not.

The debriefing process alone will take several weeks.

Then there's the question

of your physical and mental health.

Of course there's the question of my loyalty.

In my mind there's no question,

but that's my mistake Lucas.

It'll be wrong of me to trust you

because of where you've been, who you've been with,

and the threat that Russia currently poses

towards this country.

Don't take this personally.

You're home.

Take the time.

Enjoy it.

Home isn't where you live.

It's where people understand you.

If I don't have trust from MI5, from you,

then I'll never really be home.

I'll just be back in England.

We think we might have a potential Russian asset.

What have you got?

Well, if we're looking at non diplomatic targets,

then the oil company Christus Oil's the go-to destination.

Seven of its UK based employees are active Russian spies.

But the biggest fish by far is this man, Alexander Beletsky.

If anyone knows what Kachimov is up to, it's him.

He's already being mentioned as a future Russian president.

His line to the Kremlin

couldn't be more direct or more privileged.

So he'll know as much about high level Russian espionage

in Britain's Kachimov himself.

He's based out of Moscow with a house,

well a mansion really in Surrey.

Yeah, it's like Moscow and Timms.

He's got a wife, two kids, both at private school,

both with 24 hour security and surveillance.

The place is wired like a Swiss bank

and under constant watch.

Dirt.

Well for a man with presidential aspirations,

he's got an unhealthy fondness for fine art.

Not all of it kosher.

Okay, well if he's our big fish, let's hook him.

Land him, gut him, play dirty.

Mrs Beletsky.

Yes.

May we come in?

What's happened?

Hey ma'am.

Be quiet (indistinct).

Alright, get down, down, down, down, down.

Get quiet.

You're being watched Mrs Beletsky.

So lie there nice and still until your guard arrives.

Connie tells me you've been on the grid all night.

It's not the way to deal with it Malcolm.

I was here because a GCHQ listening station

picked up an anomaly on a frequency scan.

Ah, I see.

And am I going to understand the next bit?

It was low power beam at 532 nanometers,

a pulse of half a nanosecond.

I say again.

I think it may be a comms burst from a submarine.

What submarine?

Exactly.

I've been liaising with GCHQ, Naval Command and the cousins

trying to eliminate alternative explanations.

Alternative explanations to what?

To the fact that there might be an unidentified

Russian submarine in British waters.

And it definitely didn't originate from a British vessel.

Well there were none within 500 square kilometers

of the point of origin.

Are the nations with subs capable of a stealth incursion?

America but it's not American.

It's the wrong strategic theater for the Chinese.

Last known Russian deployment?

The St Petersburg.

But even she couldn't enter

our coastal waters entirely undetected.

Besides which she's currently in dock for a refit.

This is if the Russians are fluttering their eyelashes,

playing innocent.

If there's a Russian stealth vessel

operating in British waters,

I wanna know what the hell it's up to.

I need hard proof of its existence and its purpose.

Go and put the squeeze on Beletsky.

I want you to find out who they are

and I want you to bring me bits of them.

They want me to do what?

Don't turn around.

Why not?

I've got split ends.

What do you want? Money?

Just so you know what we're talking about.

This isn't Catherine Rising

painted by Peter Paul Rubens between 1609 and 1612.

You had it stolen

from the Georgian People's Public Museum 12 years ago.

Would you like it back?

Yes.

What is Russia planning?

I have no way of knowing this.

Of course you may choose to let me keep the painting,

in which case I'll reveal its provenance.

Do you think there'll be a president Beletsky

if you've been imprisoned for theft?

Because I'll ask you again

because I was brought up to be polite

and because I'm in a good mood.

What is Russia planning?

Yesterday a coded damage report

was relied to an FSP safe house

from a Russian submarine in British waters.

It was damaged in a collision of some kind.

What else?

Nothing.

Oh, there's always something.

Tell me and I'll let you keep them.

All I know is I've been ordered

to shut down Christus Oil's computer service today.

When today?

3:58 PM.

Why?

Because I do as I'm told to do.

Is that everything?

Congratulations.

Your testicles are yours to take home with you.

Last night, a fishing boat zanked off the east coast.

Now if it sankers the result of a collision with a submarine

that would explain the damage report,

the damage report would explain Malcolm's rogue comm signal.

So the submarine's still in British waters?

As of last night yes.

We also know that Beletsky was personally ordered

to take Christus Oil servers offline at 3:58 PM today.

Oh I've been thinking about this

ever since we picked up the comms burst.

Beletsky's intel seems to corroborate it.

I think they might be planning to tap a cable.

What does that mean?

Electronic data travels through fiber optic cables,

which crisscross the ocean floor.

There are thousands of them

passing billions of phone calls, emails, electronic files

traveling through a strand of glass

as thin as a human hair.

They run uncovered at depths in excess of a 1,000 feet.

Making them accessible to a especially equipped submarine.

And making it the perfect location

from which to launch a cyber attack.

Because from the deep ocean

nobody could prove that they were responsible.

Cyber warfare.

Estonia, early 2007,

a cyber attack almost took out the entire country.

The attackers send a tsunami of information,

clogs up computer, brings him down.

It sort of kills him in the end.

It's called distributed denial of service.

A sophisticated attack would instantly shut down

every computer system in Great Britain.

The damage inflicted would be on a scale

otherwise achieved only through an all-out nuclear strike.

We have less than four hours to preempt it.

We better call the JIC.

Harry, what have you come here to propose.

Shut down the internet.

Oh, shut down the internet, of course.

You know for a moment

I thought you were about to suggest

something altogether absurd.

If this country does not have internet connectivity,

then the attack cannot happen, so shut it down.

Can we even do that?

We do have a provision in place, yes.

But this notion is certifiably insane.

It is a drastic contingency,

but it's the only contingency left open to us.

It's not a contingency,

it's an error that would cost the economy billions.

You have no concrete evidence whatsoever.

This is entirely circumstantial

and one has to assume, Harry,

that you're being motivated emotionally.

I'm sorry Harry, I have to agree.

And you're wrong.

Richard, for once put departmental politics aside

and listen to what I'm actually saying.

What you're saying is that we should take

a medicine that's as bad as the malady, kill or cure.

Is that it?

Harry this is just too much to ask.

Even if I was ever mine to help you,

number 10 would never, could never allow it.

And number 10 is about to watch this country

stumble and fall.

Hello mate, got a package for Lucas North.

I don't understand.

Who better to be your handler than your ex-wife.

What?

You were-

I loved you, but I love Russia too.

How many years did I waste?

You lied to me too.

I never lied.

Did you tell me what you were?

I thought of you at that time.

Eight years, I thought of nothing but you.

You lied to me.

And now your lie is turning around and coming back at you.

What we have left is this.

Well I can't do this.

The point of me being your handler

is that there's every reason

for people who were once together

who have not seen each other for so long

occasionally to catch up, drink coffee.

What do you need to know?

An encrypted communication was sent last night

from international waters.

Has MI5 identified the source of this signal?

There's no way that I can access that kind of information.

The trust isn't there, not yet.

Well, you are the spy.

I need you to report by 3:30 PM, after that no phones.

Why no phones?

All I know, no phones.

Malcolm, we urgently need a plan of attack.

We need to get onto the offensive.

Have we got anything from the JIC?

The Joint Intelligence Committee

won't take the political risk.

They're sending us a couple of Naval technicians.

We've got three hours to avert this attack.

Well, the only thing I can come up with

is that to launch the attack,

the submarine needs to physically link

to the fiber optic communications cable.

If we can find a way of talking to the sub,

computer to computer,

I could launch a zero day attack,

effectively bouncing the cyber attack back onto its source.

It would take out the sub's computer system,

its navigations.

Would you have time to prepare the attack?

Well yes, but need to identify which fiber optic cable

the server planning to log onto.

Out of several thousand.

And even when we find that out,

I'll still need the submarines remote access protocols.

We need somebody with access to Arkady Kachimov.

one, sorry.

So how are you?

one, sorry.

one, sorry.

one, sorry.

To foil the cyber attack

we have to use the asset we have

who is closest to the Russians.

You want to use Lucas?

He has a relationship with Kachimov.

Kachimov was responsible for Adam's death Harry.

And I said we will have revenge.

This is the start.

Lucas is damaged goods.

You wanna put him up against a man like Kachimov?

I said before.

Yeah, he was one of the best, was.

If this submarine attack takes place,

it's not just the economy that will scream,

there'll be civilian casualties.

We've only got two hours

and I'm running short of options Ros.

Do you trust him?

Bring him in, let's talk.

He left his house 10 minutes ago.

You've had the place under surveillance?

- Of course. - Do you know where he is now?

No.

I'll go around to Lucas's flat,

see what he's done with the place.

Pest control.

Anything on the video surveillance?

They used to send a nice young man.

Any movement of note?

There was something earlier.

Oh crap.

Ros.

Harry, I'm afraid we've gone bobbing for a bad apple.

Lucas is a double agent.

You were right to be cautious.

On this occasion I'd be happy to have been wrong.

So turns out actually doing this

is more difficult than I thought it was gonna be.

Anyone who sells themselves was a virgin once,

and you didn't sell yourself cheap.

Eight years.

What if it had been five years? Four years? Two?

What conversation would we be having now?

This one.

Lucas, it's for the best.

MI5 never helped you.

These people, you owe them nothing.

You gave them all those years of solitude and darkness.

In comparison, this little bit of information, it's nothing.

Thank you.

Are you happy?

Happiness isn't about getting what we want,

it's about appreciating what we have.

So yes, I'm happy.

One day you'll be happy too.

You didn't really believe all that happiness crap did you?

How's the nervous system?

Twitchy.

This is a mistake.

I'm glad you didn't waste those years

trying to memorize convincing excuses.

Maybe Kachimov should add that to his curriculum.

We should be following Elizabeta.

We are following Elizabeta.

Come on Lucas.

Impress me with your ability to talk your way out of this.

I agreed to be Kachimov's agent in London,

of course I did.

But just to get back, to come home.

Governor, I couldn't rely on you to do it for me.

And you failed to mention this earlier, why?

I told you in the car.

You joked about it in the car.

You suspected it anyway. You were as good as told me.

So if I'd admitted it officially,

you'd have locked me in a cell

and debriefed me for months on end,

and I've seen enough cells.

So I decided to prove myself by bringing Kachimov to you.

This is actually rather good.

Because it has the advantage of being true.

You passed on deeply sensitive information

to the head of the FSB in London

in order to bring him down.

Yes I did.

Explain to me how that works.

Kachimov ordered me to find out about a message

that you may have intercepted,

something originating from the ocean.

And you decided to find it and tell him?

I did.

Why?

Because he knows what the message is.

He knows where it came from

and he knows that you've intercepted it.

He's testing me.

Sending me out to get something that he already knows.

It's the only way he can prove my worth as an asset

and Kachimov really, really needs to trust me.

It's his greatest vulnerability.

He's embarked on a major operation

and in the chaos that follows,

he's gonna need a man on the inside.

Because that way he can stay one step ahead

of any possible retaliation.

He wants you.

He wants all of us dancing to his tune.

If you're lying to me,

you won't get so much as a funeral.

I sent Elizabeta to meet Kachimov

because I had to get him out of that embassy.

I have to get him out and on his own

if I'm going to turn him.

I know you want him Harry.

Oh so do I.

This is your chance, your one chance, take it, now.

Right now, or let him go.

We need you to get

the submarines remote access protocols.

They'll be inside the Russian Embassy.

How much time do we have?

Less than an hour.

Okay, it looks like she's making a rendezvous.

I tell you this Elizabeta,

you go now and pick up your child

and buy a bottle of water

and canned food enough to last for one week at least,

two perhaps, three to be safe.

What's happening?

There will be unrest for a while.

So go now.

Get your child, be safe.

She went that way.

Ah I'll catch her later.

So what is this?

Surprise party, music and dancing girls.

Oh, I think there have been enough surprises for one day.

Anyway, I've got something for you.

Please go on.

There's a submarine,

spy submarine in British waters.

Today will be used to launch a cyber attack on Britain.

This is what MI5 has learned?

This is what MI5 has learned.

How do they know these things?

They have a mole.

The Russian embassy, very high level.

Who?

You.

Don't be so silly.

It's you, Arkady.

Like it or not, it's you.

Look at the pair of your so old schoolers

as if the wall never fell.

So your whole strategy is rather dependent on one thing.

Which one of you am I loyal to?

Well, it should be an easy decision,

without control over energy your country is finished.

Yeah but if I were to make a decision

based on something more than self-interest,

I could expose you as a traitor.

This is not true.

- No? - You can not make it look-

Yes I can.

No you can't, not true enough.

Well we know about the submarine attack

and we know because you told me and I told MI5.

They'll never believe you.

It depends what they want to believe

because your bosses are certainly gonna wanna scapegoat

when we decide to publicize this aggression.

If I were you, I'd keep a Geiger counter handy

because they're gonna light you up like Livinyanko

for making them look stupid.

If however, you give me the sub codes

and we foil this little plot with nobody,

any the wiser wouldn't not be better for everyone.

What delicious irony.

You are trying to tell me my own spy.

Well, let's just call it a strategic retreat on your part.

Lift a fight another day.

See it doesn't really matter if I'm not your spy Arkady.

What matters is whether you get lost in the fallout.

They've got eight minutes till the attack is due.

As soon as I access this data,

it'll set off alarm bells all over the embassy

and they will come.

Just do as you're asked, leave the worrying to me.

Yeah this is an emergency call from MI5.

Agent ID PLM29/8818181.

Code word rhino.

Repeat, code word rhino.

Please be advised, MI5 has a credible threat.

There is a bomb in the building.

Repeat, there is a bomb in the embassy.

Do it now.

Now.

Come on Lucas.

Malcolm it's on it's way.

Okay.

Okay.

It's a modified T class spice up.

The Alexi Leonov.

They breached the cable, we've got 30 seconds.

It's launching from cable number ARD 392

Deep North Atlantic.

I'm launching the zero day attack.

That's their tertiary firewall infected.

Nearly, nearly, nearly.

That's the secondary fireball.

- Now- - Wait.

Malcolm quickly.

Got them.

And this evening the Kremlin has thanked the Royal Navy

for its speedy assistance after a Russian submarine

on an oceanographic survey sank off the coast of Britain,

following what's been described

as catastrophic engine failure.

Naval rescue boats raced to the scene

after the submarine sent out a distress signal

earlier this afternoon.

Excellent news.

We've sent them a huge message.

As long as it buys me out of a six month debrief.

It's bought you a return to this section.

If that's what you want.

Of course I do Harry.

What happens to Kachimov?

He belongs to us now.

That's our revenge.

Well it seems to me the punishment doesn't fit the crime.

Kachimov is a big prize.

Don't underestimate his importance in future battles.

Exactly what Adam would've said.

It was you who said to me Ros Adam's dead

and Kachimov's responsible.

Harry, he was worth more.

I'm not sure I love what you've done with the house.

The tastes have changed.

I'm sure they have.

We have your boss Elizabeta.

You are both too.

No.

You weren't FSP when we were married.

When did Kachimov turn you?

He approached me a little over a year ago.

He told me you'd been arrested but you were alive

and that you could come home if I helped him.

Why did you say yes?

Why put yourself at risk?

He showed me photographs of you in that place, your skin.

He said it would be easier on you

if you believed I had always worked for him.

Well he's a very clever man Elizabeta

but he's not a good man.

So now? You arrest me?

I can tell you now I know nothing of value.

My friends wanna throw you to the lions

and it would be so easy to implicate you

to make it look like you and Kachimov were working together

for MI5 because that's what I am.

I'm MI5.

I was MI5 when we married,

MI5 all those years in prison and I'm MI5 now.

What are your reasons for working with Kachimov?

You need to think about protecting your family.

So let me help you.

How?

Work for us.

Were you always this cold?

Under the skin?

Was that man I knew just a lie?

If you don't let me do this,

they will take everything away from you.

This life, this happiness, it will all be gone.

I know what that's like and there are no words

to describe how terrible it is.

My husband is home.

You a range finder no?

In the British asset in Moscow.

I order your execution.

Well silly old you.

It's all over Arkady, done and dusted.

Your escort will be here in a moment or two.

I know you won't mind if I don't wait around

to wave goodbye.

So this is it?

This is it.

You won't be free, not for some time,

but we'll make you as comfortable as possible.

Until you have squeezed

from the very last piece of intelligence that I have.

You know the game.

And I bow to the better player.

I congratulate you on your victory.

God save me from many more victories like this one.

It's a pity about your man.

Carter, was it?

He's dead. That's not a pity it's a crime.

I did what I had to do for my country.

I'm not seeking forgiveness.

You'll find them.

And you will never find rest Harry,

until you have forgiven yourself.

Men like us, there is no room for remorse.

Carter was a very courageous fellow, but he was a resource

and the resources can be replaced.

There's always another courageous fellow

waiting to step into the bridge.

No.
