The vehicle's stopping.

The AFF are moving towards the lock-up.

Viktor, the AFF are entering the building.

Initial reports claim-

Harry.

Home Secretary, if you could spare us a couple of minutes,

I have Ruth Evershed with me, our Russian analyst.

Good evening, Home Secretary.

We've intercepted an email to the AFF cell in London.

We think they're trying to acquire a WMD.

It's a nerve agent called Paroxocybin.

It was developed in the '60s from an algae.

Both we and the Russians worked on derivatives.

It was banned, wasn't it?

We signed a treaty with Khrushchev.

All samples were destroyed.

The email claims one wasn't,

that it's in Azakstan, and the AFF plan to use it

against Russian troops.

Well, have you told Moscow?

You're asking me to share intelligence with the FSB,

with people who spent the last 50 years

trying to destroy us?

It's all in the past now, Harry.

Russia's an ally. We do business with them.

There's a risk Russia could acquire

the Paroxocybin for itself.

Well, send one of your officers

to witness the operation.

Home Secretary, with all due respect-

I'm not interested, Harry, in your old-fashioned beliefs.

Either do the job, or get out of the way

and let someone else do it for you.

Tariq, are you getting this?

Yep, got it

Lucas, have some vodka with me!

It's the real thing,

none of that crap

made in your country.

Bottoms up.

To many more cooperations, I hope.

What's goin' on?

No! No!

Hey, what are you doing?

Stop!

Lucas, my friend, they're terrorists!

They were here to steal Paroxocybin!

This was not part of the deal!

Get this footage to the home secretary.

Show him what full cooperation with the Russians

really looks like.

- Harry- - Tonight.

Sir, I think you should take a look at this.

There's another AFF member.

Shall I alert Lucas?

We can't just let him go.

Tango-1, we have the position of the next...

The man just lost his country.

We won't be responsible for him losing his life too.

Harry, are you sure about this?

Doubting my judgment?

No, no, I'm just saying-

We've done what was asked. That's an end to it.

Relations between Russia and the former Soviet state

of Azakstan are fraught today after the murder

of 23 ethnic Russians in the Northwest town of (indistinct).

Moscow is pointing the finger at the Azakstan Freedom Front

and accusing the Azakstan government

of turning a blind eye.

A little while ago, I spoke to William Towers,

the home secretary, and asked him about Britain's response

to these recent events.

Home Secretary, today, you banned

the Azakstan Freedom Front from London after 15 years.

Why did you do that?

It was quite a simple decision, Kirstie.

We cannot tolerate, in this country, any organization

which supports ethnic cleansing.

But you know, Home Secretary, the AFF

has denied any involvement in these murders.

You're simply caving in to pressure from Moscow.

Our course of action is determined

by Britain's stand on human rights.

It's as simple as that.

London?

Ambassador.

A small gesture of our appreciation.

Your favorite, I believe.

You are very well-informed.

Please, walk with me.

I wanted to thank you personally

for your help with our Azakstani friends.

I noticed it didn't stop you invading anyway.

Russia is simply protecting the interests

of its citizens, just as you did in the Falklands.

Of course, the two are identical.

There is one small detail.

An insurgent appears to have slipped through the net,

a man called Azis Aibek.

Really?

You weren't aware of this?

- Hmm. - Was told MI5

had the Azakstan operation under a satellite surveillance.

You know how unreliable electronic intelligence can be.

Cloud cover, microwave interference,

even sunspots, they all take their toll.

Of course, the wrong kind of sun.

Unfortunately, Aibek's escape has now become

a more serious matter for all of us.

We believe he's on his way to London

to acquire a second sample of Paroxocybin.

That's impossible. Everything was destroyed in the '60s.

It was all witnessed, documented.

As it was in Russia.

Nevertheless, as we both know, some survived.

Where is this second sample supposed to be?

Here, in London.

Unfortunately, our source was unable to be more specific.

Was?

He's no longer available to answer questions.

Some things never change.

I have to differ.

Our countries now vote together in UN.

You and I freely pass information between us.

It is a new world, Sir Harry.

We'd appreciate him being returned to us

at the earliest opportunity, weather permitting, of course.

We are not in the business

of doing the FSB's dirty work for them.

Aibek is a desperate man.

He will have have walked out to help those in Azakstan.

I can assure you he won't hesitate

to use this weapon in London

any more than he would in Moscow.

Common enemies need common friends. Sir Harry.

We have new guidelines about accepting gifts

from foreign government officials.

I'm sure you understand.

Hello?

Maya? It's me.

Just leave me alone, John.

I wanna see you again.

I wanna tell you everything, tonight.

I don't want to see you.

I don't believe you.

I'm texting you my address.

Whatever happens, I'm not gonna disappear again, ever.

Azis Aibek, one of the founding members

of the AFF in Azakstan.

A geography teacher for 10 years,

he was radicalized in the '90s

after his brother was imprisoned

for anti-Soviet propaganda.

The brother later died in a Soviet Gulag.

Aibek's last-known sighting, according to the Russians,

Lake Vrule, Azakstan.

The Russians are telling us there's a loose end.

They claim Aibek is coming here to acquire Paroxocybin,

which is impossible.

So what's the real reason?

Moscow's determined to discredit the AFF.

The more they do so, the more international support

they'll get for their invasion of Azakstan.

Catching a known terrorist on UK soil would play into that.

What better than to have British intelligence

do all the grunt work?

Quite, so our task is to determine

whether Aibek really is a threat

and head off a potential PR coup from Moscow.

Okay, Beth, distribute Aibek's details Europe-wide.

Notify all ports of entry.

Dimitri, get onto known sympathizers of the AFF in the UK.

Ruth, can you dig up everything

on the original Paroxocybin project?

Okay, that's it. Thank you.

Go ahead, Ruth. I know you want to say it, "I told you so."

If Aibek is a threat,

and the home secretary realizes we let him go-

I can deal with Towers.

No, it isn't just Towers. We have to have a strategy.

I don't need you to fight my battles for me, Ruth.

The home secretary wants to see you. Sounded urgent.

I've just had the Russian ambassador on the phone.

He thinks you're an obstructive, pompous dinosaur.

Very diplomatic.

And you know what? I'm inclined to agree.

All he was asking for was some cooperation

in the war against terror.

The only reason the Russians want Aibek

is to justify their invasion of Azakstan.

It is not the job of British intelligence

to aid in that objective.

The Russians believe he'll use it here,

and your job is to apprehend terrorists.

If you're not up to it, just say the word.

The Russians want a man on the Grid.

An FSB officer at Thames House? That's absurd.

There's a real threat here,

and your Russian expert agrees.

You've spoken to Ruth?

She's an advisor, Harry.

That's what she's there for, to give me advice.

I told the ambassador it won't be a problem,

so don't let it be.

Sir Harry Pearce, I'm honored.

Has he been screened?

Yes.

Meeting room, 10 minutes.

This is the original KGB report on Paroxocybin.

Symptoms start with convulsions,

involuntary urinations, and defecations.

Death by asphyxiation follows within two hours.

Paroxocybin is contagious.

It will take three days to infect a million people.

In less than a week, it could infect the population

of Moscow or London.

Any antidotes?

Research stopped after the ban.

There is no known treatment.

Is it easily transportable?

To remain inactive, it needs to be kept

at minus nine degrees Celsius.

Once it comes into contact with air,

it vaporizes and produces a colorless, odorless gas.

It's our assessment that if Aibek acquires Paroxocybin,

he will attempt to use it in the UK.

Why would he do that?

Because Russia and Great Britain are allies, Sir Harry.

We worked together on the Azakstan mission.

As far as the FF is concerned,

that makes you a legitimate target.

French security just reported

that Aibek boarded a Eurostar first thing this morning.

They estimate he's already been in London for over an hour.

When the French intel came in,

I ran a probability in predicting

possible locations of Aibek.

That's him.

What's that he's carrying? Get in closer.

I can try a thermal analysis.

It's lined with some sort of insulator.

He's keeping it below freezing.

Then he has the Paroxocybin.

We have to stop him before he releases it.

Got him on CCTV. East side, Trafalgar Square.

He'll head for a crowded area

to get maximum exposure for the release.

CO-19 on full alert.

Target approaching junction with Charing Cross.

Approaching destination.

Tariq, any more information on the target?

800 meters from possible interception point.

Change of plan, target is entering

Charing Cross Underground.

Tango One, Tango Two,

take the east Charing Cross entrance.

Tango Three, Tango Four, the (indistinct) street.

Dimitri, fix up that way. Beth, with me.

We have to work on the principle that he's gonna release it.

Tariq, give me directions.

Charing Cross, two underground lines,

nine exits under four different streets,

for internal levels, six platforms.

I have access to the CCTV.

Tango One and Two have reached the east entrance.

He's going to release it on the Tube.

Seal the entrances. No one in, no one out.

There are thousands of people down there.

They'll be trapped.

If he releases the Paroxocybin now,

they're as good as dead anyway.

We have to contain the damage.

I have visual, target on the Bakerloo Line,

second level concourse.

Upper entrance, eastbound platform.

I've lost him in the crowd. Do you have a visual?

Alpha One, negative.

Alpha Two, no visual.

Is he on?

I've got eyeball on target.

Has he got the package?

Confirmed.

Can we take him out?

Negative. I do not have a clean line of sight.

Target's on the run.

He must have seen us. - Don't push, old man!

Get out of my way!

Move!

- Excuse me. - Don't push, don't push.

Target's made a drop.

I'll take care of it, go, go, go!

Security services! Clear the platform, please!

This is a security alert.

Will passengers please evacuate this Underground station

as quickly as possible?

I repeat- - Package retrieved.

Is it intact?

If it broke on impact,

we have 40 seconds until contamination.

Trains are on hold. Code red.

Beth, we need to know if the canister is broken.

Beth, is it broken?

There's nothing here.

The bag's been prepped, but there's no Paroxocybin.

He musta been on his way to get it.

Then he still is.

He's gone! Regroup.

Tariq, check the vicinity. He can't have gone far.

Okay, starting to localize the search.

Found him.

Target identified near Central University,

science block, Norton Place.

You're only half a mile away.

They're two minutes away. He's at Central University.

What have I done?

Now's not the time for self-reflection.

Tariq, get CO-19 over here. Seal off all exits.

Dimitri, stay here. Beth, first floor. You, with me.

Yes?

- Dr. Kirby? - Yes.

My name Azis Aibek. I am friend of Professor Omosheva.

Did he call you about me?

Professor Omosheva is dead.

Dead?

You'd better come in.

How did Professor Omosheva die?

A traffic accident.

This can't be true.

Did you know him well?

He was good man.

I'm sure. What exactly is it you want, Mr. Aibek?

Professor Omosheva told me about Paroxocybin.

- Sorry? - He told me about the sample

he hid, and the one you had.

It was to be last resort, of course, never used,

but if the Russians knew we had it...

I have no idea what you're talking about.

I'd like you to leave now.

You are our only hope, Dr. Kirby.

Without you, my country will be destroyed.

I don't want to have to call security.

I'm sorry.

Me also.

We have to assume that Aibek is still trying

to acquire the Paroxocybin.

It needs to be stored at below zero,

and there must be a lab in the building.

Anywhere with a suitable freezer?

Dozens. It's the main science block for the university.

Check the faculty list.

See if any of them were involved

in the original Paroxocybin research team.

Come on, come on!

Meg, your daughter, you care about her?

I will find her, Dr. Kirby, and kill her.

Tell me where the Paroxocybin is being stored!

I've got something.

There's an S. Kirby on the sixth floor.

Okay, so a Dr. Kirby worked at Porton Down in the '60s.

He worked on the Paroxocybin project.

Aibek's got to be there.

Sixth floor, office 18.

Lucas, take the stairs. Dimitri, cover the lift.

Clear the area now! Move, move!

Meg, it's happened.

No, no, no, I'm fine, I'm fine.

You know what's necessary. Yeah.

I love you too.

Aibek's gone.

Get an ambulance down here now, room 618.

Hello?

Is that Meg?

Yeah, who's this?

My name is Azis. I am student of your father.

Something terrible has happened. I don't know what to do.

What's happened?

I came for tutorial and he was on the floor.

He told me he has been attacked and I must call you.

Okay, okay, let me talk to him.

They have taken him to hospital.

He give me an envelope that I must give to you in person.

Come here now.

What has Kirby said?

That he didn't tell him.

You believe him?

He was in a pretty bad way. I don't see why he'd lie.

Any traces in the labs?

C0-19 are reporting they're clean.

Bring him in.

Meg?

- Yeah. - Azis.

Uh, I'm not going to lie to you, Meg. There is no envelope.

Your father has been taken by Russian Secret Service.

They want something called Paroxocybin.

I don't understand.

I think you do, Meg.

You must take me to where it is.

Okay, this is ridiculous. I want you to go.

What do you do, Meg, your job?

Nothing.

I'm a secretary.

Meg Kirby, MSc, PhD, faculty of molecular biology.

Paroxocybin was never intended to be a weapon,

but once its potential as a nerve agent was recognized,

all other avenues of research were shut down.

Until the '64 treaty.

We were told to wipe Paroxocybin

off the face of the Earth.

I couldn't agree with that.

It was a unique organism,

and we'd hardly scratched the surface of its potential.

Who knows what benefits it might bring?

So you kept some back.

And Professor Omosheva?

He felt the same way.

We agreed to do what we could to preserve Paroxocybin

for posterity, him in Azakstan, me here.

It was the right thing to do.

Things have changed.

We need to know where you're keeping the sample, Dr. Kirby.

So you can start research on a cure for cancer?

So we can prevent a known terrorist

from acquiring a nerve agent.

He won't find it.

Aibek is a resourceful man.

He found the sample in Azakstan and he found you.

That was different, he had help,

and I'm not Professor Omosheva.

He won't give up until he finds it.

Don't you understand that?

The sample is quite safe.

And when he does find it, and uses it here,

or in Azakstan, or in Russia,

are you prepared to accept responsibility

for the thousands of lives it will take?

He will not find it.

Azis, I can't tell you what you want to know.

No!

Please.

Just tell me, please!

You're, what, 62, 63? You can't live forever.

You must have made a plan B.

What if you got knocked down?

Posterity's not much use when you're lying under a bus.

You must have told someone else.

I told no one.

I don't believe you.

You're concerned about what would happen

to the Paroxocybin if you told us where it was.

What if we gave you our word that it would be taken

to Porton Down and stored safely?

Your word means nothing, however well-intentioned.

People move on, regimes change.

In a few years, weapons research

would start all over again.

We could guarantee its destruction. You could witness it.

The last thing I want is for Paroxocybin

to be destroyed.

You don't trust us to keep it,

you don't trust us to destroy it.

Meanwhile, you're willing to risk a ruthless terrorist

getting his hands on it. - I've told you the sample

is quite safe.

Don't be so bloody naive.

Please, (gasps) no more, I'll ask my father.

No more, no more!

CCTV's got nothing on Aibek.

I bet he's sticking to side streets.

Or he's gone underground.

Storing Paroxocybin needs uninterruptible

electricity supply.

We should be checking anywhere with such a facility.

Okay, Beth, get onto the utility company.

See what they can give us.

Dimitri, run a trace on all associates

of Dr. Kirby from the '60s, and check out his family.

If he didn't talk, Aibek may try someone else.

Someone's calling Kirby's mobile.

Tariq, do a cell site analysis.

Beth, get this to Harry now.

Okay, put me through. Hello?

Who is this? I need to speak to Dr. Kirby.

I'm afraid Dr. Kirby's been admitted to hospital.

I'm his registrar, Dr. Henley.

I'm Dr. Kirby's daughter.

I need to speak to him. It's urgent.

I'm afraid that's not possible.

No, please! It's very important!

Hang on a second, I'll see what I can do.

We have an address.

You have a call.

- Hello? - Dad!

Dad, is it really you?

Meg, you okay?

I'm with a man called Azis Aibek.

I'm so sorry, sweetheart.

No, it's okay.

I'm sorry.

Pactum serva.

Pactum serva.

- Pactum serva, Dad. - What you saying?

- Pactum serva! - Give to me!

If you want to see your daughter alive,

you will tell me where Parox...

Pactum serva? Keep the faith.

What you say to him? What's it mean?

It means you've lost.

Meg's apartment is the second floor

of the old flour mill.

ETA one minute, Lucas.

Tell me!

No.

It's okay.

That's it, that's it.

It's okay.

I didn't tell him.

I have to talk to my father.

Of course.

I didn't tell him anythin'.

I know, but you're going to tell me.

Don't move!

I think we need to have a talk.

Get him back to the Grid.

What happened?

I tried everything I could. It's my fault.

She fell unconscious after you left.

I couldn't bring her back. I'm sorry.

Did she say anything?

No.

Aibek?

He got away.

Back to square one then.

Yeah, back to square one.

He murdered her, Harry.

Are you sure about this?

When I left the room, Meg was definitely alive.

- Viktor? - Claims she slipped

into unconsciousness.

I called the morgue and there were no signs

of a ligature, but if he drowned her,

the post-mortem results would look the same.

Harry, our Russia intercept team has intel.

There's an order from Medevac flight, London to Moscow.

And the Paroxocybin must be readmitted

to cryogenic storage within 72 hours.

They've been using us to track Aibek.

Why?

They want the Paroxocybin for themselves.

It appears I have allowed us to be played by Moscow

right from the start.

Well, not right from the start, Harry.

It wasn't why you let Aibek go.

But by allowing him to escape, I did the Russians a favor,

and I have to admit, that was my mistake.

Mistake of judgment, maybe,

but not of decency.

Sometimes, you have to do what's necessary, Harry.

Dr. Kirby.

Is it about Meg?

I'm afraid so.

I'm sorry.

How did she die?

She was drowned.

I'm afraid she told Aibek what he needed to know.

No, never.

One of our officers was with her,

and before she died, she told her.

No one could blame her.

Even a trained officer in those circumstances

would only last a few hours.

We can still save the Paroxocybin

and stop the man who did this, Stephen,

bring him to justice, but not without your help.

You have to tell us where the sample is.

You have a choice, Aibek.

I have no choice.

Is finished.

My country's under Russian control.

I could not stop them.

Don't give up so easily.

Time to make yourself useful. We have a plan.

You have to say this is the perfect place.

Uninterrupted electricity, industrial freezers.

Harry, package is on its way.

Come on, Viktor, bring your camera.

Aren't we going to follow them?

Change of plan.

That was not the deal, Lucas.

I need to witness the Paroxocybin being destroyed.

Oh, you will.

Convoy on the move. Back-up in position.

Copy. Porton Down aware.

A decoy. MI5 never ceases to impress.

Aibek's still out there.

We can't afford to take any chances.

Let's go.

Get him! Get him!

Lucas?

Lucas?

Idiot!

Viktor, put it down.

It's a war, Lucas.

If you don't like it, look the other way.

Please, I did everything you ask. Stop him!

Please!

Lucas, what have you been doing, huh?

We don't make deals with terrorists.

He was a loose end, for all of us.

So are you.

Don't be ridiculous, Beth.

Meg Kirby was alive when I left the room. You killed her.

Lucas, tell the new recruit how the real world works.

I already have.

Viktor, Viktor, look at me. Stay with me.

Tariq, call an ambulance.

Help's on its way. You're gonna be fine.

Come on. Come on!

We're losing him. Viktor!

Dimitri, Aibek has escaped with the Paroxocybin.

He died trying to protect us all.

Harry.

Ambassador, on behalf of British Intelligence,

I would like to present Viktor Barenshik

with this posthumous McGough Medal.

I'm honored to receive this, Sir Harry.

Viktor dedicated his life to peace,

and in the end, lost it to the same cause.

This honor would have meant a great deal to him. Thank you.

I'd like to assure you personally, Ambassador,

that we're doing all we can to retrieve

the stolen Paroxocybin.

Isn't that right, Harry?

Of course.

Thank you so much for coming, Ambassador.

Bloody cock-up, letting Aibek escape with the Paroxocybin.

I understand the Azakstani government

persuaded the Russians to withdraw.

Didn't have much choice, did they?

Not with the other side possessing a WMD.

I suppose not.

Oh, get out, Harry.

Home Secretary.

John, they're gonna kill me.

Why? Whose life did you ruin this time?

You've changed. Why can't you believe it in me?

Listen, I just need a file.

It's in Five's archive. It's called "Albany."

Look at me, John. I just want out.

I wanna get this over with and disappear, forever.

You know what that feels like.

Yeah, I know what that feels like.

And I want you to disappear as well,

but I'm not gonna help you to do it.

Have you told Harry Pearce what we did?

Don't make me use what I know.

Come on then!

In fact, I'll help you to do it.

Tell him now.

Huh? No?

Thought not.

Thank you for seeing us.

You know I have no choice.

Your daughter did not break her promise, Dr. Kirby.

An officer was with her when she died.

She kept the faith to the very end.

You lied to me.

Yes. I'm sorry.

It was necessary.

So some crackpot terrorist organization

can't get hold of it.

Another success for British Intelligence.

I realize you are a highly-principled man,

Dr. Kirby- - Spare me platitudes, please.

I am therefore going to tell you something

which I probably shouldn't.

The Paroxocybin, your Paroxocybin,

was taken under armed guard to Porton Down,

where it will be kept in secure storage.

But the newspaper reports. They're-

Not always accurate.

And the AFF? They have nothing?

They have what they need,

Russia's belief that they possess the power to strike back.

The driver will take you home.

If he talks, you'll lose your job.

Yes.

You'd lose everything.

Possibly.

He won't talk, though. He's an honorable man.

You can't know that for sure, Harry.

Sometimes you have to give a man a chance, Ruth,

to show you who he really is.

You lie to me and I swear you will never see me again.

Okay. Come in.

Why did you let me believe you were dead?

All right. I went to prison for eight years.

Is that good enough?

Prison? Why, did you kill someone?

No.

Did you hurt someone then?

No.

I suppose you're innocent.

No.

Why did you decide to turn up now?

Photograph of you.

All those years I spent tryin' to forget

just fell away.

I had to see you.

Is that true?

Every word.

I don't even know you anymore.

Yeah, you do.

Oh,

I've forgotten.

Close your eyes.

You'll remember.

Close your eyes.
