Who are you, Abby?
Joe, we could spend
all night talking.
You're probably the same age as me.
I know that.
The woman in the hotel,
she gave me this.
I've got something a USB.
- You remind me of my dad.
- Ah.
I hate my dad.
We've got it.
It's the Blue Blockade group.
They're a group based out of Tehran.
This isn't just a hack any more.
It's an act of w*r.
I'm not saying that it isn't them.
I'm just saying that we still
don't know that it is.
I think we should hack Miller.
- Are you in?
- Uh-huh.
Over the last few weeks,
Miller has been in communication
with one person
more than anyone else.
You need to speak
to Downing Street, Kate.
This isn't just about cancelling
next week's announcement.
Remove all traces of it, okay?
You don't think
that this is connected to Mashhad?
I don't know what to think.
(Hud) You're gonna have to come up
with a very good reason
as to why the code used
in this attack
happens to have been written by you.
- What am I looking at?
- The faces.
(Abby)
There's someone else on the train.
What?
Stop!
Put your hands in the air!
(g*nsh*t)
(women screaming)
What did he do?!
What did he do?!
- He's been shot!
- (Joe) Get down!
Get down! Stop!
Stop!
Stop!
Hands in the air!
(Yas gasps)
(screams)
Get out the way!
Please!
Please!
Please!
I'm sorry!
I'm I'm sorry!
Wait! Wait!
It's okay.
(breathing heavily)
He He's okay.
I It's not what it looks like.
- You knew he was on the train?
- It's not Billy's fault.
I just didn't know what to do.
I-I didn't know what to do.
Please, Joe.
I'm sorry.
Please.
(groaning, whimpering)
There.
There we go.
- Aah!
- You're all right.
Stay with me.
Just look at me.
Nice, deep breaths.
Just look at me.
Look at me.
Look at me, okay?
Just stay with me.
(groans)
We're okay.
We're okay.
- (groaning)
- Yeah. Yeah.
(phone ringing)
(Saj) This is Saj Sidhu.
I need you to speak to me.
Alpha-Lima 7,
this is November-Charlie 1.
Could you get your team
back alongside the train?
We need to see what's going on
in there.
Over.
(man)
November-Charlie 1.
They cannot fly alongside an active
sh**ter for obvious reasons.
Out.
You are in charge
until further notice.
Do not mess it up.
Hey.
What are you doing, Nicola?
This is not about
what I've been doing.
It's about what she has.
I've known Abigail
since she was a child,
- and she would never
- Doesn't mean you know her now.
Maybe not, but he does.
He He lives in her spare room,
for God's sake.
How well can you ever know anyone,
really?
- I-I haven't written any
- Take a seat.
- Come on. You can't think that I
- Sit down.
- The idea that I
- What?
Pose a threat to national security?
Is that incredible to you?
Really?
Even though you've done it before?
(Billy)
I knew we had an unbooked cabin,
and I was meant to have the day off
tomorrow
before doing the return leg
overnight, so
What?
I asked him if he wanted to come
spend the day in London.
We were going to see a show.
- Jersey Boys.
- Oh, come on!
I swear. It's true.
(Yas)
Billy.
I swear, Yas.
(Draycott) So why didn't he come out
when this all first started
or when we left Motherwell?
Or when we hit a goods train?
Or when we found out
That the person who installed
the device in there
might still be on board?
You think that's a good time?
When you find yourself in the middle
of what might be
some t*rror1st incident
to say, "Hey, everyone.
Here's Caleb Mahmoud"?
I'm sure you wouldn't have judged him
at all.
- Not like you're judging him now.
- Oh, so this is about us?
I came over here four years ago
with with my little brother.
We applied for asylum, but we still
don't have leave to remain.
I-I can't even work.
Getting in trouble with the police
is not something
But if you leave it all this time,
and then charge out
talking about Jersey Boys,
you can't be surprised
if we have a few
No.
I have more than a few doubts.
Every single night, all I do is smile
and get people what they want
and apologise for things
I have absolutely no control over.
And the one time
the one time I break one rule
and do something for me
No.
All right.
Answer me this.
Straight yes or no.
Did you have a satellite phone
in there?
One that's still working,
that you were using?
- No.
- Yeah. Right.
(Joe)
This was found in a cabin near yours.
Know anything about that?
- No.
- That could be anyone's.
People bring them on board
every week in season.
Hunting, sh**ting.
As long as they're locked away
and they have a permit
(Rachel)
Help! We need help.
The accountant.
H-He's losing so much blood.
All right.
Get him into one of the cabins.
Come on. Help carry him.
Go. Let's go.
(Abby)
Could you, um
Could you open the door?
I don't like closed doors.
You're not in charge in here,
I'm afraid.
You're not in charge anywhere.
Am I under arrest?
No.
This is a conversation.
Right.
It's just that you bringing me
into the clean room,
like some sort of
cyber Hannibal Lecter, kind
Your words, not mine.
kind of suggests
that I can't leave.
Oh, of course you can leave.
You will be arrested then, though.
Let me tell you.
The Greyhat programme, um,
continues to be
a significant bone of contention
between agencies.
Recruiting cybercriminals
to tackle the growing cyber threat?
- What could possibly go wrong?
- I was 15.
You can't hold that against me now.
Hacking into GCHQ
is a serious offence at any age.
Yeah?
Well
worked pretty well for me.
Yeah.
Certainly did.
It's not a punishment I'd recognise.
Funded through university,
given a job at the end of it.
No one has worked harder.
No doubt.
The NCF, Ukraine.
It's been quite the rise, hasn't it?
Not just fast-tracked
but given the keys to the kingdom.
(door opens)
Ma'am.
Come on.
You need me out there.
I mean, all this is a lifetime ago.
So you're different now?
Yeah.
I am.
About 20 minutes ago,
did you or did you not launch
a phishing attack
against your own director general?
(Miller) I don't care if you
or anyone else likes me, Abby
or values me or even trusts me.
Because I know who I am what I am.
And I will tell you this.
Never, ever take me for a fool.
Studying your communication
for information
that may aid me tonight doesn't make
me a threat to national security.
But you withholding that information
from me,
well might make you one.
We've got a match.
(Saj)
Yeah?
- (Tobi) Caleb Mahmoud.
- Iranian?
Syrian.
Asylum application still pending.
- Uh, any red flags?
- No.
Uh, Zed, get hold of his caseworker.
What
What exactly is happening with Abby?
Not now.
- But
- Listen. We need to focus, okay?
You can't seriously believe
that Abigail's got anything to do
with this.
Do you think that I want that to be
the case?
I think you are exactly
where you want to be.
(exhales sharply)
- And you're not?
- No!
This is what has kept me awake
at night for years.
- Yeah?
- Yeah.
All right. Well, now you can
actually do something about it.
Do you know what, Pev,?
You're the last person I'd call
at half past midnight, okay?
But you are the first person
I'd be calling now,
so you need to decide if you're
more interested in her career
than their lives,
because if you are, there's the door.
And if not, stay here and help.
And actually,
that goes for everybody else.
We've got a job to do,
so can we please get on with it?
- (Erin) We need towels. Clean towels.
- (Moy groaning)
Yeah. Yeah, yeah, yeah.
I'll get some.
(breathing heavily)
What were you
You what, mate?
doing with my r*fle?
You see?
I was just trying to protect
everyone.
- I thought he
- We know.
- Well, you rammed into me.
- I thought you were gonna sh**t.
(Joe)
Only if he'd pulled a g*n out first.
How long have you been seeing him?
- What?
- How long?
I don't know.
Four months.
- Tomorrow.
- (Rachel) So
(Draycott)
So you hardly know him!
He could've been playing you
just to get close to someone
- who works on the train.
- No.
- No. You're wrong.
- I think you need to quit, too.
I don't think you're the person
to tell anyone
that their career is over, do you?
Don't you put that down.
(Moy groans)
You're supposed to wash out a wound,
aren't you?
I d I don't know.
I don't know!
- Have we got any vodka?
- I think he had the last of it.
You s
You shouldn't use alcohol on a wound.
It It can damage the tissue,
stop stop it healing.
I'm I'm a nurse.
I was.
Yeah?
Well, keep him alive.
Abby, are you there?
- Abby?
- Guys.
Uh, i-is that Joseph?
Uh, J-Joseph Roag?
- Who's this?
- (fingers snapping)
Uh, my name is Sajinder Sidhu.
Uh, now, we heard a g*nsh*t
before we lost you.
Have there been any injuries?
Uh, yeah.
The accountant's got a stomach wound.
It's pretty serious.
He needs proper medical attention.
- Is Abby there?
- Yeah. What about the minister?
Yeah. Yeah, yeah.
She's fine.
As is everyone else,
thank you for asking.
Uh, who fired the shot?
Caleb Mahmoud?
You've ID'd him?
Was Mahmoud the sh**ter?
No. No, no, no. It was, uh
It was an accident.
Yeah.
Who fired the shot, though?
Uh, I don't I don't know.
It wasn't clear.
I don't think anyone saw.
- Surely the accountant must know.
- Sorry.
Can I speak to Abby, please?
Abby's not available at the moment.
What?
Yeah.
She's a little bit busy.
Uh, but look.
I, um
I need you to do something
for me, Joseph.
(Hud) CSJIF That was
your big break here, wasn't it?
Remind me what that stands for.
Cyber Security
Joint Intelligence Force.
Right up your street,
I should think.
Hacking enemy state infrastructure.
Rolling out the ambassador's
reception and all that.
- All authorised at the highest level.
- (Hud) Indeed.
And this attack tonight, it's
straight out of their playbook.
Wouldn't you say?
So what?
Saj was part of that as well.
Why don't you haul him in here?
Saj was the one
who traced tonight's hack to you.
(knock on door)
(lock beeps, door opens)
Hey.
Need a union rep?
(Miller)
Uh, you left the union years ago.
Yeah.
Well, you can't interview her
It's a conversation.
What do you want me to do, kid?
Uh stop the train, Pev?
- (cup sliding)
- For you.
Cheers.
Yeah, yeah, yeah, yeah.
(door closes, lock beeps)
Look. I am not responsible
for the code used tonight.
- No?
- No!
So you don't recognise this?
Did you write that, Abby?
sh*t.
Yeah.
Would you like to state
exactly what you wrote it for?
Mashhad, ma'am.
That is part of the attack program
for Operation Mashhad?
Yeah.
(Hud) Now, as you know
I'm not a technical fella.
So I want you to answer
the following question
in the simplest possible terms.
What was the aim
of Operation Mashhad?
To hack a train.
(beeping)
Yeah.
I'm at the device.
Right. I need you to plug that phone
back into it.
Why?
What exactly do you want to do?
Just do it. Please.
(Mouse)
Why have you still got that g*n?
(metal squeaking)
They've switched lines again.
They're not going towards Leicester.
They're going
towards Burton-on-Trent.
- (Saj) Why?
- (Zed) They could get back
on the West Coast Mainline
at Tamworth or switch at Birmingham.
Still here, then?
Yeah.
Following her orders, not yours.
So, what are you gonna do?
Okay.
I found a match for part
of the train system's attack script
in the code library,
enough to speed up the clone sift.
So, whatever they've done
to hide the real SBC,
we can at least narrow down the data
to focus on the vulnerability
that they're targeting.
And if that works, we should be able
to isolate the real SBC.
And hit the brakes?
Abby was really clear that nothing
should be done
without being tested
in the sandbox first.
Yes, she was.
But she is no longer here, okay?
And if we do nothing,
that train could come off the line
right in the centre of Birmingham
within the next few minutes.
(Rachel) Tonight hasn't been
quite the career turnaround
either of us were hoping for,
has it?
It could be, though.
There are many versions of all this
for both of us.
And we can either sit back
and let someone else write them or
- What do you want?
- An interview.
(Abby) Classified code
gets leaked all the
(Miller) It's more than just code,
though, isn't it?
You were technical lead
of Operation Mashhad,
an attempt to remotely take control
of an Iranian rail convoy
believed to be transporting
nuclear material.
- And you succeeded.
- Yeah, for about two whole minutes.
So you wanted to go one better?
I didn't have anything to do
with the train side of things.
That That was my predecessor.
Ma'am, you need to get me back up
there and
What?
What have you accomplished so far?
You've lost control
of the entire rail network
- and made a new mum a widow.
- Hud, please.
And what have you people done?
Bar setting fire to the train
and dragging me in here?
Um, actually, we've just detained
two individuals from the incident
at Glasgow Central, so
What did they say?
All claiming to be hired hands
with no knowledge of the objective
or scale of the attack.
Approached by social media
and offered large sums
for specific tasks.
- By who?
- The account is fake.
So if you know,
if you were approached
and you have accepted money,
then believe me, now,
whilst most of the people
on that train are still alive,
is definitely the time to say.
Look.
I was worried about Mashhad.
I said that to you, that this
might have been some sort of revenge.
But I don't think it is.
I think Iran is being used
by somebody
who knows about all this
to make it seem like it's them.
- Come on. We're getting nowhere here.
- No, but
Okay.
We could.
Ma'am, what were you talking about
in those e-mails to the minister?
Why not mention that you were
in constant contact with her?
Nicola, she is not interviewing
Hey.
No one's interviewing anyone.
It's just a conversation, all right?
You go into it everyone does
because you want to change things.
You look around at the mess,
and you want to fix it.
But when you're in it
you realise there's
just so many vested interests.
I mean, it's obvious.
Of course it is.
But until you're in it,
you don't realise that all of
all of the power is with them
not you.
I'm sorry.
I don't really
Just be clear, will you
that I was dead against it,
that I did everything I could
to stop it.
I want you to be clear about that.
I want you to report the facts
accurately.
What facts?
U.K. rail that is all the track,
lights, signals, infrastructure
was about to be taken back out
of the public sector,
broken up, and sold.
To who?
I was reliably informed that none
of the favoured bidders are UK-based.
And one of them was a French company
you may now be familiar with
called VoyaRapide.
See, this is why I needed to know.
These are highly confidential
discussions.
If I were seen to be the source
of a leak
I would never!
I have spent day and night
raising my concerns
as to the potential security risk
of selling off critical
infrastructure in that way,
of having no idea who the
ultimate owner of it might be.
But Draycott was in favour?
What do you think?
She's the transport secretary.
She wants to be home secretary.
She probably wants to be
prime minister.
She's desperate
to drive things through and move on.
Well, that's not going to happen now.
Wouldn't think so, would you?
Do you really believe that her being
on this train is a coincidence?
(Miller)
I don't know, Abby.
But you, of all people,
should've known
not to see deep-state conspiracies
all around you.
Just because we walk in the shadows
doesn't mean we're there
to do people harm.
We're there to keep them safe.
So why have you stopped
believing that of me?
(Hud)
We don't operate on belief.
We operate on evidence.
What are you doing in my flat?
Hoping we don't find any.
Right.
Is that better?
(Moy groaning)
(Caleb)
It's okay. You're okay.
(phone ringing)
- (Miller) Are we in?
- Yeah, we're in.
Tobi's just writing a counterattack
for the cloning program
so that it doesn't trigger
the same response as last time.
How long will that take?
Ten minutes, but I'm aiming for two.
Can we access the brakes from here?
We can, but it doesn't mean
it's a good idea.
Yeah. I'm not gonna do
anything dramatic, okay?
I'm just gonna bring the speed
of the train down very slowly.
(water running)
(Sophie)
Been waiting for you.
- (water stops)
- Always wanted to try it, you know?
The first-class experience.
Aye.
Well, what do you reckon?
I think you'd get a better night's
sleep strapped to the roof.
I've been carrying it around
since Motherwell.
You know, all all night,
I've been saying to myself,
"You can get through this.
You've been through hell before.
You made it out the other side."
But the
the thing that pulled me out
it was Kyle
and my my sisters.
I wasn't alone then.
And
I don't I don't know i-if I can
(exhales deeply)
Problem solved.
That was disgusting, by the way.
(keys clicking, computer beeping)
Done.
Then let's slow this thing down.
Here we
go.
(Moy groans, Yas gasps)
What was that?
- (Chrissy) Are you okay?
- Yeah.
- Yeah?
- Yeah.
It It's speeding up.
Uh
W Um
Hundred and ten miles an hour.
(track rattling)
No.
They're heading into Birmingham.
- Wait. Wait.
- (Pev) It's another tripwire.
Everything you do is having
the opposite effect.
Okay. Okay.
Look.
Maybe we should try
intentionally speeding it up.
Please, please quit
while you're behind.
(mobile ringing, buzzing)
- (groaning)
- It's okay. It's okay. You're okay.
Why are we going even faster?
This is too fast!
(ringing continues)
(male announcer) Did you really think
it would be that easy?
(female announcer) Did you really
think it would be that easy?
(both) Did you really think
it would be that easy?
(announcement continues,
voices echoing, static hissing)
- (man) Sir?
- I'm here.
We've seized a number
of network devices.
We found a laptop.
It seems to be running an encrypted
virtual P.C. in the background.
We need the admin password
to expose it
without triggering a disk wipe.
Is this
And that is?
- I have no idea.
- Oh, I hope you do.
Because if you don't,
you'd look like an awful lot like
someone with something to hide.
(mobile ringing, buzzing)
Yeah.
Hello?
What's going on?
Yeah. There was a complication,
but we are looking into it.
All right.
Where is Abby?
I'm afraid that Abigail Aysgarth
had to step off this operation
permanently.
So you need to listen to me.
Listen.
- Okay?
- What?
Because I am in charge now.
His His heart's stopped.
Hello?
Hello?
They're beyond maximum speed.
(defibrillator chirps, clicking)
- (male voice) Stop CPR. Analysing.
- Stand back!
- (male voice) Shock advised.
- Stand back!
(male voice)
Press the flashing shock button.
(defibrillator beeps,
electricity crackles)
Start CPR.
(breathing heavily)
Come on!
Come on!
(male voice)
Stop CPR. Analysing.
(gasps, exhales deeply)
(Fraser)
Listen. It isn't just him.
We're all gonna die
if we don't do something about it.
Maybe let's put that down, eh, mate?
You think her lot give a toss
about what happens to us?
They're too busy covering
their arses!
We are on our own.
So we can either sit here
and wait for help,
which will not happen,
or we can save ourselves!
Look.
I know these trains.
This one's been tarted up a bit,
but they're all the same underneath.
The power is in the locomotive.
That's what's pulling us along.
And I don't think we've a chance
in hell
of this train not going where
the b*stards that are driving it
want it to go.
Look. That doesn't mean to say
that we have to go along with it.
We might not be able to stop
the whole train
maybe nobody can
but we can stop half of it.
(Saj) Excuse me.
Is anyone there?
- Are you there?
- It's bypassed Birmingham.
It's now travelling
on the Chiltern Main Line.
We seem to be looking at
High Wycombe, King's Sutton,
and then London Marylebone
is the end of the line.
I don't think there is any way
we could have actually anticipated
- that they'd rigged the whole
- Oh. "We," is it?
We need contact, Saj.
- I know, ma'am.
- What, then?
Well, look. We just need to rewind
the clone sift a bit.
Because obviously that was not
the right interface.
- And then
- Rewind?
It is almost 04:30 in the morning,
and the train is getting closer
and closer to London,
but you're telling me that your
solution is getting further away?
Nicola.
Nicola, you have to get Abby
back in here.
- The code used in that
- It's more than the code now, Paul.
One of the laptops in her flat
has an encrypted virtual P.C. running
in the background,
and she's refusing to give us
the password.
Come on. There could have been
anything in there.
I agree.
And none of it is gonna be good.
(siren wailing in distance)
Are you seriously considering this?
Well, of course not.
We just need to sit tight and
What, die?
Well, is it even possible
to decouple a train
- while it's still moving?
- Moving really, really fast.
The Mark 16 locks electronically.
There'll be decoupling switches
in that office.
- There are.
- And personally,
I wouldn't rather go
near that wee machine.
- I don't trust it an inch.
- All right. So
So we can access the same wiring
from this carriage.
There's points in every carriage.
All we have to do is break
the connection,
trick it into thinking there's
something there that isn't,
and then tidy out everything there
that we can.
What, and it'll just
just come apart?
I don't know.
Never been tried before.
And I'll need tools you know, like
a proper kit or I can't do it.
There's a lot of stuff in the office.
How dangerous are we talking?
It's not gonna get passed
by Health and Safety.
Look.
We would be fools to try this, right?
That is the truth.
We're short on things that we need
if things go wrong.
But we would be bigger fools
if we just didn't do anything.
Okay.
Uh, this is not up for debate.
I've done what I can, but
but he is in very serious condition.
If we do not get him
off the train soon
Yeah.
I'm in.
Look.
There will be a plan in motion.
- We just have to trust
- Me too.
Right. Okay.
That's four then.
Well, Jersey Boys doesn't get a vote.
- Typical.
- Democracy is democracy.
Screw democracy.
- Oh, is that right?
- Filthy.
Uh, all those in favour,
raise your hand.
Look.
I'm sorry, Chrissy.
- For what?
- For shouting before.
You'll never need to apologise to me.
Okay.
Well, that's good to know.
'Cause if you don't raise your hand,
I'm gonna do it again.
I've been trying to get you
off this train since Motherwell,
and I'm not gonna stop now.
- I thought you quit.
- Yeah. Not being me.
- (Saj) Joseph?
- Hello?
W-What What's going on in there?
Hello? Did you hear me?
I said
(Joe)
Yes.
Yes, I heard you.
Don't worry about it, mate.
We'll take it from here.
- Hello?
- (line beeping)
Right. Look.
I can't give you a password
that I haven't set.
I have to break it to you
in case you're somehow imagining
that we won't ever be able
to get in there.
We almost have.
Do you Do you have any idea
the amount of hours I've worked
in the past few months,
the time that I've spent here?
When I finally get home,
do you really think that I jump
straight on my laptop
and begin all of my secret,
nefarious cyberwork?
(mobile chimes)
What?
When the history of tonight
is written,
long after we're all gone
I hope people realise
that we would never have done
what we did
if you'd just taken the opportunity
you had and told the truth.
What?
- What
- (lock beeps)
What are you gonna do?
(hand thuds)
This is actually very satisfying.
It won't work.
It can't.
Last one.
How's it going?
I think I've been retired
longer than I thought.
I'm gonna go and help them.
Okay?
I'll
I'll just be out here.
(Moy)
Don't leave me.
Please.
All right!
Let's get on with it, then!
(grunting)
Aah!
(Tobi)
Hey.
The helicopter feed just cut off.
Alpha-Lima 7,
this is November-Charlie 1.
We have lost the feed.
Over.
Alpha-Lima 7?
(metal creaking)
How is another train moving?
Do I really?
What?
Remind you of your dad.
A little bit, yeah,
if he'd had money.
Whoa.
No, no.
You see, I-I didn't always
- Try not to speak.
- I did not I
- Honestly. Just
- No.
I used
I used to be something else.
Someone else.
Yeah.
You
You start off by putting it on.
You know, at work.
To fit in, to
to be like one of them.
They take you sh**ting,
and you pull the trigger.
You have to be the best shot.
You have to look that deer in the eye
and feel nothing.
Why did I go, huh?
Why did I go?
(sighs)
(gasps)
Hey!
Hey!
- (woman screams)
- (Joe) Is everyone okay?
Right. We're nearly there.
Come on.
(metal creaking)
I think it's this one!
I think if we cut it,
we should detach.
- "Think"?
- Yes!
I just don't know!
Okay.
Are we doing this?
Yeah.
This is my last plea for sanity!
Wait. Wait! Everyone hold on
to something, all right?
Okay.
Go.
(electricity crackles,
metal creaking)
It's not working!
No!
it's nearly there!
Just needs a wee shoogle!
Is there anything we can use to give
it a whack and help it on its way?
No!
Something bigger!
All right.
Let's find something!
(monitors beeping, phone ringing)
(knocking)
Ma'am, I am sorry to come in here
like this,
but there appears to be
another moving train again
and it's moving towards ours.
Could you close the door, please?
- What I'm about to say never
- Nicola. Nicola.
- No. They need to know.
- You leave. You leave.
(Miller)
They don't need to leave.
He has made decisions like this,
and one day he will.
What decisions?
It won't be moving for much longer.
The Heart of Britain
is going to be stopped
has to be stopped
before it reaches London.
Oh, about three hours ago,
we were all on our knees
because Abby just about moved
a goods train.
And now we're putting one there
deliberately?
Someone has to make the decisions
no one wants to.
We don't have the luxury
of pretending there are good options
- when there are not.
- Well, we could pay the ransom.
There has been no movement
from either VoyaRapide
or the French state
regarding the payment of any ransom.
And there isn't going to be.
It's not what they do.
And as you know, it's not what we do.
But what, we cause accidents?
Only if it prevents much worse ones.
You shut down the helicopter feed
so there'd be no record
of what's about to happen.
Saj, you had your chance.
I wish you'd taken it.
There are passengers on board!
A b A boy.
Do you know how many people live
in Central London?
How many children?
Do you know what the effect will be
when something of that speed
and weight derails?
Ploughs into the boiler house
at the end of the line?
- Well, if Abby was here
- (Hud) Oh, Abby.
- "If Abby was here."
- What does that mean?
They've cracked the virtual PC.
It's full of malware
that we've created,
tools we've created over years,
the kinds of things
that do not and cannot leave
this building.
She may or may not have something
to do with this,
but either way, she's gone.
That train does not get into London,
and we none of us
are to blame for anything.
(Chrissy)
What about the wheelchair ramp?
About time it was used for something.
(sighs)
(rattling)
(lock beeps)
- Ready?
- Yeah!
Three, two, one!
For God's sake!
(metal clanging)
It's not working!
Come on!
- Aah!
- (indistinct shouting)
You all right, Billy?
You all right?
Yeah.
Okay.
Where's Fraser?
- What?
- Where is Fraser?
Fraser!
Look.
I am in complete agreement.
If you can't make these decisions,
then you shouldn't be in the job.
(door closes)
- He's not in his cabin.
- And the toilets are empty.
He's not gonna be over there!
And if he is, it's not on us!
- Don't! No!
- Joe!
Hello?
Are you there?
(Fraser wheezing)
Jesus, mate.
What are you doing?
Why'd you come back here?
Bloody hell, mate.
I'd have bought you another one.
We need to get you back across,
all right?
Hey.
You're definitely coming back.
Right.
I'm gonna get help, all right?
(indistinct conversations,
phones ringing)
He's here!
I think he's had a heart attack!
- No. No. No.
- I can't move him on my own.
Don't Don't
Don't let me fall, okay?
(metal squeaking)
(gasps)
You stay here with him, yeah?
No! No!
I can't not, remember?
(Rachel)
No!
You bloody idiots.
Fraser.
Fraser, you're all right.
- You're okay.
- Get this table up.
(Sophie)
We're gonna get you up, okay?
- You hear me?
- Three, two, one.
There you go.
- (Sophie) You're okay.
- Three, two
- There we go.
- (Sophie) Okay.
(Fraser grunting)
(Joe)
There we go. There we go.
Go on.
Up you get.
There we go. Come on.
Let's get out. This way!
(Miller)
How long until King's Sutton?
Two minutes.
(Leon)
Can that be moved, ma'am?
No, Leon.
I don't believe it can.
Hey.
What are you doing?
Ma'am?
Ma'am, I think I know
(Hud)
Stay exactly where you are.
- I know how to stop it.
- Wait.
(Abby)
What if
What if it's all from us?
Not just the train hack,
but the antivirus too?
What if the methods,
the work being used here, are ours?
What if this driver is using us?
Look.
The French covered up
a data leak, right,
showing that the
crypto-authentification chips
they were using were vulnerable
to attack.
But that doesn't mean
it's the only thing that was.
If they have used the code I wrote
for Mashhad,
then maybe they've used the same
vulnerabilities as we did too.
The firmware
in the logic control board.
Yes!
And unlike the chip,
that can be fixed from here.
- It is patchable.
- There's a CVE code for it?
Yeah.
We don't need to find
the real interface for the device.
Use their satphone to update
the train's systems, and we're in.
Ma'am, look.
I won't stay where I'm not trusted.
I'll leave tomorrow.
But please
please let me do this tonight.
This doesn't change what she's
done what we know she has.
The stuff on her computer
That alone is
That is not mine!
(Hud)
Then who else? Who else?
I don't know!
Oh Tobi.
Tobi, Tobi.
You really are here for the toys,
aren't you?
I never did anything with it.
Nothing bad.
I
I just I just like to see
how things work.
I
(Abby)
Ma'am?
(Miller)
Oh, God.
(train rattling)
(Joe) Nearly there, mate.
Come on. Nearly there.
- (Fraser wheezing)
- (Joe) That's it. You got this.
You got this.
That's it, mate.
(metal screeching)
(Pev)
It's switched lines again.
(Miller) I've never been so relieved
the train's one step ahead of us.
It isn't going east to Bicester.
It's going south, towards Oxford.
(mobile ringing)
Hello?!
Hello. This is Liz Draycott.
- Are you there?
- Yes.
- Can you see what's happening?
- Yes, we can.
And you don't need to worry any more,
because we know exactly what to do.
Abby?
Yeah.
Minister, you just need to take
this phone to the manager's office
and connect it up,
and we'll do the rest.
Well, how do I do that?
- What?
- It's coming apart!
The switch of lines
just opened us up!
It's coming apart!
(train rattling)
Come on!
Hurry up!
(indistinct shouting)
- (Billy) I've got you.
- It's coming apart!
Please!
We can make it!
(electricity crackling)
- It's coming apart!
- No!
(Rachel)
No! No!
- (screams)
- No!
(Draycott)
Oh, God!
- (Pev) Ugh.
- What?
Look.
It's split apart.
Tell me you are
in one of the carriages
towards the back of the train,
Minister.
(Draycott) I am!
But what about the others?
Are my team okay to go in?
We need you to keep everyone
on board.
If you had something to do with this,
what half would you rather be on?
- I thought there was meant to be six.
- Armed police! Hands in the air!
(Abby)
Who's gone?
Okay.
First things first.
Any doubt that anybody had about me,
it should absolutely remain.
Tonight's hack-jacking code is mine.
(train rattling, metal creaking)
- It's never gonna work!
- (grunts)
(Miller)
None of it matters now anyway.
A decision has been taken
at the highest level.
There's six still lives in there.
We can't just give up on them.
(Hud) A tactical intervention
is no longer an option.
The word "hack-jack" is now trending,
and your failure is about to be
everyone's breakfast viewing.
- (man) What's happening?
- Joe?
Backs straight against the chairs,
facing away from the impact.
- Will that even help?
- Yes.
