All language subtitles for Nightsleeper S01E02

This programme contains some
strong language

I'm on a train called
the Heart of Britain.

It's the Glasgow to London
night service.

The wiring in the floor's
been tampered with

and there's a device attached.

One of the UK's biggest
antivirus firms has a virus.

Just leave it to us.

Before we left the station, there
was an incident on the platform.

A lad stole a bag.

Police!

It must have happened then.

Saj, the critical infrastructure
that uses the antivirus? Yeah.

It's not the UK rail network, is it?

Is it an explosive device?
No, it's a hacking device.

There's currently an Interpol red
out for someone on that train.

What are the chances?
This is ridiculous.

Hey!

He actually used to be a DI
in the Met.

Who's going to have
operational control? You are.

You mean it? Do not, under any
circumstances, call Paul Peveril.

They're saying it's left
the station again

with some passengers still on board,
but without the driver.

Any driver.

Every train across the country
stops right now.

Mouse! Mum!

Passengers are reminded that
that my name is The Driver.

I'll help you. But you're going to
have to help me too.

Why would I possibly do that?

I mean, how can I trust you?

Abby? I know what you're thinking,
how it looks, but

I haven't hurt anybody, all right?

I was one of the good ones, I was.

I haven't done anything.

And right now, we need each other.

So all I'm asking is that
when I've helped you,

you keep me out of custody
till my trial.

OK?

OK. Here's how it starts.

You need to ask the police
to track down

the two guys who ran out of
Glasgow Central.

We need to know where they came from
and who they were with.

I'm just going to find out.

Yeah. I'm going to put you on hold.
Meg, look after this. OK.

Mate...

PHONE BEEPS

What's going on?

What are you doing?!

Excuse me. No, not now. Hi!

I'm Abigail Aysgarth,
acting technical director

of the National Cyber Security
Centre across the road.

I'm...aware of all the glitches
across the network.

Can I check your systems?

Er...

OK.

Cyber security? Good luck.

What problems have you got in here?

Well, you know that all trains have
been grounded, every single one?

Yeah. I ordered it.

Well, look at that.

RTV - Real-Time Train Viewer -
should show the position

of every train in the country
at any given moment.

It's how we stop them colliding.

The whole system's down.

Network's currently littered
with passenger and goods trains,

all stopped where they shouldn't,
when they shouldn't.

So we're just blind.

I hope your message got through -

because if any are still moving,
they won't be moving for long.

Hey! Could you step away
from that, please?

Do you know what's happening? I know
the driver's still on the platform.

What?! Right, I need to get into
his cabin.

You can't. There's no driver.

We need to get into his cabin now.
OK.

A Class 94 is not accessible
when moving.

Door to the driver's cabin's
at the front.

That's why they put an engine
between us and it.

Close it up.

I thought you wanted us off?
Where's that cop?

Why are we moving?
My lad's still on the platform.

He's still at the station.

Has anyone seen the boy?
Who's still on the platform.

You all right, mate? Yeah, I'm OK.

His mum's been left behind.

Give me my phone. One sec.
Is this to do with the hack?

What?

What?!

The wiring was tampered with
in the manager's office

before we left Glasgow.

There's been a device installed,

and a phone jammer that's presumably

meant to stop us
from doing anything about it.

By who?! I don't know.

But he's been in touch with
the National Cyber Security Centre

through that.

PHONE BEEPS

Call through to the driver.
We need to go off at Carstairs.

He isn't on board either.

What?! What?! What?!

What?!

Billy? It's true.

Who's driving, then?

I don't have all the answers.

Cyber Security Centre has actually
got me on hold at the moment.

No, someone else is in there.

Someone else is driving this train.

Yeah, someone else is driving,
but not from in there.

I think we're being
controlled remotely.

Yeah. I don't follow.

We appear to have been hijacked.

Hack-jacked.

Hijacks are so 20th-century.

It just ran a red
before Wishaw Central.

It should not be able to do that.

The red should trigger an automatic
safety response on the train,

putting the brakes on.

What, the fail-safe failed?

Yeah, well, antivirus
does have a virus.

And, Abby?
The minister is still on board.

Look, I've set up calls
with the train operating company

behind the Heart of Britain
and Five Eyes to see if anyone

has any idea who or what this driver
might be.

Yeah. Yeah, OK.

Listen, you need to prioritise
regaining access to something called

the Real-Time Train Viewer
over everything else.

Right now, we literally have no idea
what's around the corner.

Abs?

Meg, this is not the night
for Marrakech.

Well, yeah, well, I would go home,
but you've cancelled my train.

Look, is there any way that
you could stay in the station

and let me know if anything else
appears on those boards?

ON PHONE: Yeah. Er, one question.
Er, yeah?

How? Er...

I don't know, but maybe it's worth
us trying to track back the guys

who ran away from the police
at Glasgow Central.

Who were they with?
Where are they going?

That is a police matter.

No, everything tonight
is a cyber matter.

And if you could check out
the DI's case

and get a comms plane dispatched
to fly over the train

and figure it all out,
in the time that it takes me

to climb seven flights of stairs.
I would really appreciate it.

Hey. I'm so, so sorry.

Mmm.

I need new friends!

Yeah? Yeah.

All right? Yeah. OK.

Right, good luck. Hwyl fawr!
Love you.

It is impossible for anyone
to operate this train

without a driver. I disagree!

On what basis? It fucking is doing!

Hey, hey! Ray? He's an old man.

I'm not too old
to deal with you, pal.

ALL SHOUT

PHONE BEEPS

Joe? Shush!

Shush!

Hi. Have you got an answer for me?
Yeah.

We are looking into your case.

But listen, the Transport Secretary
is on that train,

and I need you to give this phone
to her.

Which one of you
is a Transport Secretary?

What? Erm...

Hello, everyone.

They want to talk to you.

Jesus.

The one person I wouldn't want
in charge of a situation like this

is a member of this government.

That is so bloody true.

Oh, please tell me
I'm not stuck on this train

with a bunch of bloody
Guardian readers!

Sh!
Hello. This is Liz Draycott.

Why don't we just... Why don't
we just stick with this guy?

Yeah, that's not going to happen.

Why not?
He's the hero of Glasgow Central.

He is the reason the police
were at Motherwell.

Do we really have to
bring this up now?

Are you at the train manager's
office yet?

Look, I need to make a lot of calls.

You're not making any calls.

Sorry, what's your name?

It's Abigail Aysgarth,
acting TD at the NCSC.

Well, listen, Ms Aysgarth,

I'm the permanent
Minister for Transport.

And I have to tell you, being
trapped on a train without a driver

is the worst possible
development for me,

so calls are going to be made.

Now, I need to ensure
that I am off this thing

before anybody else out there
knows I'm on it.

That phone is used to converse only
with us and to connect to the SBC.

That little flashing device in front
of you with the aerial on it, yeah?

That is what's controlling
the train now.

I need you to link the two by USB
and get me that phone's IP address.

Do you have any idea how to do that?

I co-sponsored last year's
ICT and telecommunications bill.

Do you have any idea how to do that?

No.

That's OK. I'm going to put you
through to my colleague

who will talk you through the plan.

And we're going to pull
all the data from the SBC,

put it in a little safe place
called a sandbox,

figure out how to stop it
and get it right back.

OK?

OK.

Hello, Minister. Tobi here.

OK.

Well, look at you!

What, dressed for Marrakech?

Sounding like a technical director.

Hey...can we skip the hugs
and get straight into business?

And that is why I like you.

There's been a hack check in.

Hey, my colleague's coming down
in a minute, but can we...?

Sure.

It's the Heart of Britain
night sleeper service

from Glasgow to London.

Oh, the new 94s with the Mk 16s?

Yeah, I believe so.

There appears to be
phone jammers on board

which have delayed
raising the alarm.

Hand over your phone, please, sir.

What about UK Rail?

Under attack from its own antivirus.

But we have still got control
of the points,

most of the signals.

Most of the trains are grounded.

There's glitches everywhere.

And we haven't got access
to something called the RTV.

So you can't see anything
that's in the train's way.

Can't we just cut the electric?

West Coast Main Line,
that is electrified, isn't it?

Won't that stop it? Not with
the Class 94s - they're bimodal.

What?

They've got diesel backup.
They can still run for hours.

No, you need to speak to the TOC.

Who?
The train's operating company.

The thing is,

they're built by X, owned by Y,
leased by Z, maintained by...

Oh, should've started with
a lower letter, shouldn't I?

You've got TOCs, ROCs,
ROSCOs, DUs and FOCs.

This is why I need you.

Abby.

Could I...?

You did tell her I was coming?

Ma'am... In private.

This must be very painful for you.

This man has upset everyone
it's possible to upset.

I called it, you ignored it,
and now look where we are.

He is the Michelangelo
of mansplaining.

I know stuff that
other people don't.

Am I meant to keep it a secret?

You leaked confidential information
to the public.

I tried to alert the public
to the dangers because you...

Because you thought
you should have my job.

You Liz Trussed your way into that
position, ignoring every warning,

and now you've just got to accept...
He leaves! I'm leaving!

Do either of you even care
about the people on that train?

This is not the time for
"I told you so's".

And, ma'am, this is currently
a severe threat to life

and nobody understands
the complexities of transportation

better than him.

Please put your faith in me
and let us through, cos,

well, my pass is at home,

the only thing I've got in
my pocket is £200 worth of dirham,

and I'm pretty sure the guard's
not allowed to accept that.

Yes!

Erm, the minister has,
somewhat reluctantly,

granted us access to the SBC.
We're pulling the data now.

What I always say - there's
the right way, the wrong way

and the railway.

Oh, God. It's Obi-Wan in a gilet.

Still can't do lifts.

LIFT: Doors closing.

So I searched this property
when I was with the drug squad.

I found some cash, booked it in,

then the suspect comes back
and claims there was a load more.

That's what they do,
they try and hold things up.

Only then, Professional Standards
are on it.

They decided I'd taken the money.

You were charged?

I didn't take anything.

You ran, though.
I went into hiding, yeah.

Don't take that as a sign of guilt -

take that as a sign I wasn't
too keen on being locked up

with the person I just arrested.

What a bag of shite!

I'm still on here because of you.

They knew they had to
get us all off,

but they couldn't open all the doors
because of you.

Excuse me. We're ALL stuck on here
because of you.

You're still here
cos you wanted to finish your drink.

Look, I'm sorry.

It's OK.

How is it OK?
I think you need to leave.

I would if I could.

No, down the other end of the train,
away from us.

Mmm. Yeah. Agreed.

Yeah.

So...

..are you going to go willingly...

..or not?

Right, we have pulled all the data
from the SBC and isolated it.

Now, the code is camouflaged, but
I'd hope we'd be able to crack it

and use a satphone to put it back
onto the train within half an hour.

What about the RTV?

Yeah, OK.
One thing at a time, all right?

Yeah, that's not
going to work tonight.

PHONE BEEPS

That was triggering.

Standing between two old people
who hate each other

is taking me right back
to family holidays.

Elvis is in the building!

MURMURING

Er, yeah, for those of you
who remember Pev,

this is his comeback special.

Catch him here tonight
for one night only.

And for those of you who don't,

well, try not to be offended
cos that is just the way he is.

Where is everyone?
Trying to contact them.

There's quite a lot of
"Do not disturb". OK.

Er, Pev? Yeah.
Take over Saj's desk.

You're in charge of taking control
of the RTV.

Hang on a minute. What are you
doing? Do you understand it?

I'm getting there, all right?

Do you?
Better than I understand myself.

Hmm!

Right.

Ma'am, even though we are acutely
aware of the unprecedented events,

I am confident that we can bring
this under control within minutes.

PHONE RINGS

OK. Sorry.

All ready?

All ready.

ANNOUNCEMENT: ..are reminded
to pay 600 Bitcoin

to account 3FZbgi29cpjq2GjdwV...

Erm, it's about ten million quid.

..or London really will be
its final destination.

What does that mean?

It means the train
is now a guided missile.

Really? Yeah.

DEVICE BEEPS

All right.

OK, everyone.

Everybody? Up here.

It's almost 0100 hours, and
a ransom demand has just come in,

which suggests we are dealing
with organised criminality here.

Leon, I want you to lead a team
focused on the antivirus virus

and ensuring we keep control of as
much of the rail network as we can.

Zed, you're all about the train.

I want you to pull as much cord
as you can from that SBC,

work in the sandbox
and find that kill switch.

Then we can send it back to the SBC
via the minister and the satphone

and regain control.

Both of you report to Saj.

Saj, report to me.

Right?

Come on!

This isn't some company going down,
this isn't money being lost -

this is imminent threat to life
and this is on us.

Tobi? The minister?

She... She hung up.

CALL DISCONNECTS

OK, great.

Where were you going? Oh!

You've got a bad habit
of appearing out of nowhere.

Tell me I'm not the only one
who can see you.

I mean, if you were hiding, like...

..what's made you come out?

Why WERE are you going to London?

You're not getting out.
We're stuck in here until it stops.

I'm not.

I'm not.

BANGING

GRUNTING

DEVICE CHIMES

Oh, fuck.

Mark Hudson,
senior field at security,

liaising with Police Scotland
and military response.

Anything that isn't our domain
is his.

Hud, this is Abby, acting TD.

What? Where's Pete?

Peter's been off for months.

You know, I really think
we could do with Peter tonight.

Peter is at the point
where every single incoming email

is causing his... You thought it
was fine for the technical director

to go on their holidays.
Now you think we need two?

Yeah, well, a lot can happen
in an hour.

Get him in. No.

Abby...is definitely in charge.

Gave you a job to do.

Firstly, and most importantly,

I do not work for you,
I work with you.

Never, ever forget that.

Secondly, we have dug into
a shitload of CCTV

from Glasgow Central and
we don't believe that anyone else

boarded the train or left it
in the ten minutes of interest

leading up to its departure.

So whoever installed the SBC
carried on to Motherwell?

And is either one of the majorly
pissed off 108 people

we're currently holding
in the waiting room there, or...

One of the 12 still on the train.

Not the policeman, though. Former.

He's the only person who actually
stays inside of the cameras

for the entire ten minutes.

Did you look into his case,
the detective?

Yep. Sending over the details now.

He's got multiple commendations
from his chief.

His record was basically A1

until he tried to slip 200K
into his back pocket.

Oh, he's done close protection
and K&E hostage negotiation.

We could be lucky
that he's on there.

We will not be working
with him again.

Can you put Special Forces
onto the train from the air?

Subject to ongoing assessment,

but the initial response was
"Not at this speed" -

too many tunnels, bridges
and overhead wires.

You are aware there's been a demand?

Yep, some twats already tweeted it.

Six twats retweeted that.

Seven, eight...

Hud, Abby has been working on
a strategy that could allow us

to crack the code in a sandbox here

and use the satphone on the train
to inject it back into the SBC.

Nicola, I don't know
what the hell any of that means.

We could stop the train.

Clearer.

Is the electronic intelligence
aircraft on its way?

A comms plane? We ordered one.

This isn't Deliveroo, my love.
You don't order - you request.

We need to know how that single
board computer is being controlled.

I'll take it up the chain.

Room's ready for Cobra, ma'am.

And BBC News are chasing
for a statement.

Let's reveal that the network is
currently subject to a cyber attack,

but keep the fact that there is
an active hostage situation

out of the public domain
until we've resolved it.

And how long exactly might that be?

Minutes?

Minutes.

And there won't be a collision
before then?

We can't say that
because we can't see anything.

But what I can say is that
we've got our best man on it.

COMPUTER CHIMES

So sick to get to work with you.

Everything you've done
since going private, it's like...

..pretty much the model for me.

Well, it shouldn't be.

This, here, if it works -
if it's allowed to -

is the best place in the world.

I'm...only here for the toys.

If I had it my way, we'd get rid
of governments all together.

Sure a good algorithm
could do it better.

Oh, God help us.

He wouldn't need to any more.

Oh.

PHONE: You've reached the voicemail
for Daniel Geoghan. Leave a message.

I've got every faith in you, Pev.

Yeah? Well, normally...

..that would be well placed,
but...can I...

..tell you something in confidence?

I am currently under the influence

of my first Class A substance
since the '90s.

It's been six years since I left HQ.

I thought it was finally safe to,
you know, let my hair down.

You got any more?

I can get rid of it.

Take it.

This is no time for a come-down.

Can I help you? I'm assuming
class divisions no longer apply.

Criminals and standard.

You remind me of my dad.

Oh!

I hate my dad.

I won't be checking tickets.

Hi, everyone. I'm Billy and...

..my colleague Yas will be
getting everyone's details

for the authorities.

Delay Repay is not going to
touch the sides here.

This is a train operator's dream -
driverless train on the main line.

They won't see this as a warning.
They'll see this as the future.

Christina Doolan,
223 Haverty Street, Ealing.

Are you OK?

I've been better.
Aye, and been worse.

ARRAN: Guys. Guys!

We're going to be all right.

How will we? Can you imagine
how many Government agencies

are involved in this right now?

We will be fine!

CUTLERY CLATTERS

What are you doing?

I'm just making a note
of everyone's names.

What?

Why?

I'm...a journalist.

Oh, for f-...

Yes, I'll hold.

That... That's my private phone.

It's been nationalised.

I really need it tonight.

Not as much as me.

Thank you for holding.
I'm afraid the Cabinet Secretary

can't be reached
at the moment, ma'am.

Yeah, I don't think you understand
how important this is.

TOBI: Abby? Got the CCTV back.

It shows the guy who snatched
the bag at Glasgow Central

meeting the woman he snatched it
from an hour earlier.

It was her bag he snatched.

And what happens between this
and Glasgow Central?

OK, so these three go straight
to the concourse,

but the one with the pram goes
into a hotel near the station,

is there for about 25 minutes.

Why not go straight
to the station too?

Speak to Hud, see if they can
get footage from inside the hotel.

If not, get it yourself.

I know you didn't take it -
the money.

If you'd taken loads of money,
you'd have better clothes.

No, I mean, like...
I like your clothes, but...

I think you look quite like me.

Yeah, like a mirror.

No, not now, but when I'm older

or you when you were younger.

You got kids?

CONVERSATION IN FRENCH

Er, je...

Who is this?

Er, it's the guy from Voya Rapide.

The company that runs
the Heart of Britain is French?

Yes, well, the TOC is.

But the carriages are owned
by a ROSCO that's German

and the locomotives run under
contract by an FOC that's English,

who leases them from
a separate ROSCO - Spanish. OK?

Abby. Acting technical director.

PHONE TRANSLATES

We're trying to establish
whether you're aware

of any vulnerabilities within
the train's systems

that might have enabled this?

PHONE TRANSLATES TO FRENCH

TRANSLATION: There have been
no issues at this end whatsoever.

Our systems and our partners
are robust.

HE SPEAKS FRENCH

And it's clear to us that
generational underinvestment

in your transport network
is to blame.

HE SPEAKS FRENCH

This is a UK issue,
not a French one.

With all due respect,
this is not the time for...

Good work, director.

Hey, I know this is awkward, OK?
Mm-hm.

Obviously, when I said
what I said this morning,

I wasn't expecting to be
spending the night with you.

I'm not bothered about that,
all right? You seem bothered.

If you want to end a relationship
the night before you go off

on your wild weekend? Relationship?
Slightly overstating it.

OK, so it wasn't even
a relationship now, yeah?

Hey, for you not to call me

when you found out about the virus
just because you were...

Oh, my God, I did not call you
because you were on holiday.

I was at the airport!

Yeah, well, I didn't know
your flight was delayed.

PHONE BEEPS, LINE RINGS

Minister, pick up!

PHONE RINGS

RINGING STOPS, SHE SIGHS

LINE RINGS

Excuse me.

I've got the details
of everyone still on board.

Have there been any messages
for me? Nope.

When there is - WHENEVER there is -
can you let me know?

Mm-hm.

PEOPLE CLAMOUR, PHONE RINGS

We're dealing with it. Now, go on...

INDISTINCT

Hello?

Kate, it's me.

Oh, my God, Liz! Are you OK?

What do you think?

There's a multi-agency
response under way.

They're throwing everything at it.
We need to come up with a strategy.

Liz, you're in the middle of a
critical incident - forget policy.

You need to speak to
Downing Street, Kate.

This isn't just about
cancelling next week's announcement.

This is about...
Liz, we're all acutely aware

that something like this
happening a few days before...

Remove all traces of it, OK?

All traces.

Do we have access to the RTV?

We have progress.

Not the same thing.

Ma'am.

Abby, a word in private.

Hud has been instructed to get the
military fully involved and ready.

No-one is going to pay that ransom,

so if we don't take care of this -
if YOU don't - they will.

And things may get very, very messy.

Does anyone object to me
having a drink?

No, I think that's a good idea. OK.

So what is it you do, then?
Ignore reporters.

The prices are in there.

I'm not paying.

Now, come on. The least
you can do is make this a free bar,

considering the circumstances.

I think alcohol is the last thing
we need right now.

Ha!

You speak for yourself, eh?

Actually, I'll have a glass
of something.

There we go, that's the spirit.

Now, everyone in favour say aye.

IN UNISON: Aye.

We're making progress on the SBC.

Where are you at
on the network virus?

I'd say we're looking more
in terms of days.

Er...

Do you know the problem
with this place?

It's that I never really
fully feel confident

that the person I'm talking to
hasn't spent their weekends

rifling through my phone and email.

Mmm.

It's not the same for you, Leon.

You know the red lines.

You need to forget them tonight.

Get in to Voya Rapide's systems.
Do whatever you need to do.

I think they're covering something,
a system weakness.

If we can find their vulnerability,
we can patch it.

Mmm?

Yeah.

Do that and you're dead.

They slow it down when we corner.

Big corner, big chance.

Abby, I think we're almost there
with the code on the SBC.

If we could have communication
back with the train to upload it,

we should be able to stop it.
Great.

PHONE: You've reached the voicemail
for Daniel Geoghan. Calling her.

Leave a message.

Minister, we need that phone line!

OK, let's do this.

Ready? OK?

COMPUTER VOICES: We regret
to inform you that...

..we regret to inform you
that access is denied...denied.

See it, say it, sorted...
See it, say it, sorted...

NICOLA: What's happening?

It's a tripwire.

The SBC's interface basically
appears to be cloning itself

many, many times,
hiding the real one.

Meaning?

It's not one step forward,
TWO steps back, ma'am...

It's about 7,000.

Yeah, and counting.

We regret to inform you...

You having a drink? No, no. No.

Thank you.

Come on.

Oh, no, I don't...

You're one of us now.

Quintinshill soon.

What?

Quintinshill.

Worst rail crash in UK history.

230 dead.

Many more injured.

Many, many more.

You really think you can make it?

Soon find out.

What about me?

I could have said, you know,
that you were in there.

But I didn't cos I knew
you didn't want me to.

So why won't you do something
for me?

Don't leave me.

All right.

All right.

How is it possibly all right?

They're taunting us.

How long will it take now
to find the right interface

and do what you thought
you were about to?

Not minutes. We haven't got hours.

When the minister calls back,

I could try and play with the SBC
directly and drop the sandbox.

This isn't a game.

This is about people's lives.

We test everything first.

Speed it up,

and put Saj back in charge of
regaining control of the RTV.

We need it now more than ever.

This isn't an accident
waiting to happen -

it's a massacre.

And your pick...

..is doing nothing to change that.

He is working on it.

Is he?

Is he under the influence
of something?

Ma'am, he's trying his best.

And I'm doing mine.

PHONE RINGS

Minister, hello.

Oh, hi. Are you ready for me
to connect it again?

Hello?

What have you been doing?

Look, I told you, didn't I?

Right, I've got a list,
the host has,

of the people still on board.

Do you know how long this will take?
I've got a lot of calls to make.

Hello?

Hello?

Is the host there right now?

Yes.

Could you pass the phone to him
for a minute, please?

What? Please?

It's the cyber security centre.

They want to speak to you.

Hello. Hi. Listen,

I don't want you to give this phone
back to the minister.

I want you to turn around,
find the policeman

and give it back to him.

Where are you going?

OK. Even if we did crack
the SBC just then,

we couldn't have stopped the train

because we didn't have contact
with it.

Excuse me!

Why? Because the Secretary of State

seems so focused
on saving her own skin.

She's in a very difficult situation.

Well, what the fuck are we in?!

ALARM BEEPS

You told me that I was in charge.

This is what it looks like.

And if I have to make promises
I can't keep, then I will,

because I don't care
what this guy might have done -

I care about what he CAN do.

You're all the same.

And you accept full responsibility
for that choice?

I do, ma'am.

PHONE CHIMES

Five Eyes in your office.
Two minutes.

KEYBOARD CLACKING

Nothing by 1:30...

..and Elvis leaves the building.

Excuse me.
What's that light for? Sorry.

OK.

Do you know that Peters left?

Couldn't they get him back
for just one night?

Hey. Sorry I'm late.

If you have any leads on
this "Driver", now is the moment.

I'm sure we'd all accept that,
after Russia and China,

there is one state that hacks
on an industrial scale

that we do not like to talk about.

And I think we're going to have to
discuss "l'elephant dans la piece",

don't you?

Yeah, but France doesn't hack
French companies, does it?

It hacks us for them, so...

My team is going to send through
everything they can

about something called
the Blue Blockade Group - BBG.

Well, er, I know it,

but they've never done
anything like this before.

No, but our latest HUMINT
suggested they were planning to.

And where are they getting
their resources from?

They're a group based out of Tehran.

No-one's really thinking the fact
that your Transport Secretary

is aboard is a coincidence,
are they?

I think we all need to accept
this is just as likely to be

the work of a politically motivated
group as it is organised crime...

AUDIO DISTORTING: ..and I know that
is not what you want to hear.

No...

Yes! Huh?

VIDEO GAME: Yahoo!

Hey!

What have you done that for?

You might like it on here.

I mean, you're getting paid.

Should the chance present itself,

I think the rest of us
would quite like to get off.

Here.

She wants you.

DISTANT: If you had HUMINT,
why would you not share it?

We have to protect our sources.

We have to protect each other.

Yes, but if I may...

Abby? Are you there.

Joe? Where is she going?

Apologies. This is a very
difficult situation. Joe.

I'll do my best for you...

..if you'll do your best for me, OK?

You can't choose a criminal
over a member of Parliament.

In the Venn diagram of the two?

I think there may actually
be quite the shared area.

I'm not a criminal.

I was wrongly charged with a crime.

Minister, he's the one
who called us,

he's the one who's trained for this,

and he's the one who I believe

has the best chance of
stopping that train, OK?

Abby, I'm all yours.

What do you need?

I really don't like how dependent
we all are on that one phone.

I'd feel a lot better if you could

find that phone jammer
and shut it down.

Do you know
what you're looking for, Joe?

Yeah, I think so.

Right, it's about this big,

it's got an antenna on top,
its own power supply.

Check the bags. Every one.

About the size of a shoe box.

Abby. Comms plane's almost reached
the train, ready to scan a signal.

We should know exactly what's
going on in there within minutes.

Thanks. Tobi, stay with Leon

and report straight back to me
the moment you have a result? Yeah.

Ma'am. Mr Peveril.

Er...

Oh.

ROCK MUSIC BLARES
Woo!

Did you do it?

Did you doubt it?

Send it. Sent!

Oh!

And with the Heart of Britain's
location in real time,

you're welcome.

Woo!

When I grow up,
that's who I want to be.

What's that?

It's a goods train.

Stalled.

With its engine and half its load
straddling the West Coast Main Line.

JOE: All right,
you keep searching here.

I'll check the next carriage.

I'll help.

Stop that!

Hello, West of Scotland Signalling?

Hello, Cowlairs.
This is Abigail Aysgarth.

I need you to move what appears
to be a substantial goods train,

currently stationary
on a stretch of track,

crossing over two lines
at Gretna Junction.

Can you do that immediately
for me, please?

No.

Excuse me?
That is beyond our jurisdiction.

You'll need to talk to
the control desk down at Manchester.

On it.

Ma'am.
TV: All trains have been

brought to... That's our train.
Social media footage...

No!
..suggests some are still moving.

Got it.

OK, Manchester,

0161 496 9865.

Direct comms with maybe two thirds
of our trains are currently down.

Do you have a mobile number
for the driver, maybe?

I thought we did,
but it seems to be out of date.

A name, then?

Erm... Harvey Driscoll?

Pev. Yeah.

Control, what are the goods
on the train?

Tankers. Containing?

Natural gas condensate.

OK, thank you.

Driver. Already ringing.

LINE RINGS

Come on, come on!

Come on.

What else have you got?

Abby, what else have we got?!

Abby? Are you there?

Joe. I found something.

Hey, hey, you need to move everybody

out of the front carriages
and prepare for impact.

What? Why?

There's a train on the line
in front of you.

PHONE RINGS

Hello? Hiya. This is
Harvey Driscoll. Harvey! Harvey!

Harvey, hello. This is
the National Cyber Security Centre.

We need you to move your train
fully off the Glasgow South Western.

All trains are currently grounded,
I'm afraid. Harvey...

I'll try and give it...
..I need you to move your train.

..can't guarantee anything.
We've spoken to the control desk.

Er... Listen.
..I've got very little battery.

What's that?

There is another train
that's not grounded

and it is moving towards you.

Well, stop that, then...

LINE DISCONNECTS

We can't... I...

Everyone needs to move
down the train now.

Why? Now! Now! Come on!

We're going to hit something.

Hit what? That!

Come on!

LEON: Estimated time
till impact, 90 seconds.

Oh, Jesus! Come on!

SHOUTING

Come on.

Come on. Quick.

Come on!

LEON: 70 seconds.

Look.

ENGINE RUMBLES

Come on, quick. Come on!

PEV: It's moving.

WHEELS SQUEAL

Joe?

Come on!

30 seconds.

20.

Come on, come on, come on, come on.

Get up. Get up. Come on.

Ten seconds.

Joe!

Joe?

I'm not sure the person
who installed that device

is in the waiting room
at Motherwell.

I found a firearm.

Don't trust anyone.
