0:00:02 > 0:00:03'Under 15, a world without adults.'
0:00:03 > 0:00:06- What are we going to do?- 'You must travel to the Sparticle Project'
0:00:06 > 0:00:10and realign our dimension with your dimension.
0:00:10 > 0:00:11What's that building?
0:00:11 > 0:00:13A nuclear power plant. I think something's wrong.
0:00:13 > 0:00:16- It's insulin. I'm diabetic. - I know what you're thinking.
0:00:16 > 0:00:17Stay out of my head, Reese.
0:00:17 > 0:00:20- I think a lot about you, Tee. - I know you do.
0:00:20 > 0:00:23- Hand it over, Fizz. The Dictaphone. - Come back with my train.
0:00:58 > 0:00:59What date is it?
0:00:59 > 0:01:02Two days until we get into the Sparticle Project
0:01:02 > 0:01:05and deliver the front door key to Kat and crew.
0:01:05 > 0:01:07No. What day of the month is it?
0:01:07 > 0:01:08Oh, it's the 16th.
0:01:08 > 0:01:13- So it's definitely the 17th of October tomorrow?- Definitely.
0:01:13 > 0:01:16- What is it, Tia? - It's my birthday tomorrow.
0:01:16 > 0:01:20Oh, I get it. You want a party, but we're stuck on a train.
0:01:20 > 0:01:22No, Callum! I'm turning 15.
0:01:22 > 0:01:2715! At midnight I'm going to disappear into a parallel dimension.
0:01:27 > 0:01:29That so bad?
0:01:29 > 0:01:31- I'm joking, right?- Well, don't.
0:01:31 > 0:01:33What if my body parts get scattered in space
0:01:33 > 0:01:37- and I don't make it through in one piece?- It's not going to happen, Tia.
0:01:37 > 0:01:40It's easy for you to say. It's not your birthday tomorrow!
0:01:49 > 0:01:52I don't understand what you're getting all moody for.
0:01:52 > 0:01:54Well, say something.
0:01:54 > 0:01:56Look, one last push, one more day
0:01:56 > 0:01:58and we'll be at The Sparticle Project.
0:01:58 > 0:02:00I bet you Callum's waiting for you.
0:02:00 > 0:02:01- Us.- We need to eat and rest.
0:02:01 > 0:02:05- Have you forgotten about the nuclear power stations?- Hardly.
0:02:05 > 0:02:08So if we don't bring back the adults, the whole planet's
0:02:08 > 0:02:11- going to go toxic, big time. - Not tonight it isn't.
0:02:11 > 0:02:14Tomorrow is going to be the biggest day of our lives.
0:02:14 > 0:02:18- We need to be rested for it. - But...- Look! No. We're going to kip
0:02:18 > 0:02:21here tonight and then we leave first thing in the morning. That's final.
0:02:25 > 0:02:28Ami, don't forget your insulin.
0:02:30 > 0:02:34- Where's Reese?- I won't miss that when life goes back to the way it was.
0:02:34 > 0:02:38- What's that?- Not hearing you say, "Where's Reese?"
0:02:38 > 0:02:40Let's hope she's gone for good this time.
0:03:02 > 0:03:06Sadiq, you sure we're safe here?
0:03:06 > 0:03:08Gates are locked, Jordie.
0:03:08 > 0:03:10It's odd.
0:03:10 > 0:03:14All this food, games and stuff on the lorries...
0:03:14 > 0:03:15Why aren't there any kids around?
0:03:17 > 0:03:19Level nine!
0:03:19 > 0:03:21Nice dog.
0:03:22 > 0:03:24Get out now! Unlock the gates!
0:03:27 > 0:03:29What's the matter with you? Let go!
0:03:29 > 0:03:31Take her.
0:03:34 > 0:03:36Sadiq!
0:03:45 > 0:03:47Think we've sussed the lack of kids.
0:03:49 > 0:03:53- Ami!- It's his diabetes. Where's his insulin?
0:03:53 > 0:03:56It's in there.
0:03:56 > 0:03:58We need to get to a hospital. I'll get the map.
0:03:58 > 0:04:02- But there won't be any doctors. - No, but there'll be insulin. Quick!
0:04:05 > 0:04:08We'll never be short of things to say for Show and Tell
0:04:08 > 0:04:11when we go back to school.
0:04:11 > 0:04:12I don't want to go back to school.
0:04:12 > 0:04:15I've learnt a lot more since the adults disappeared.
0:04:24 > 0:04:27Tia's turning 15 tomorrow.
0:04:27 > 0:04:29She's not going to vanish, is she?
0:04:29 > 0:04:31I mean, that can't really happen, can it?
0:04:34 > 0:04:39- We need to go right.- Then go right. - The points are set to the left.
0:04:39 > 0:04:44- The brakes... Apply the brakes! - It's not going to stop in time.
0:04:49 > 0:04:50We're going off course.
0:05:06 > 0:05:10- Now what? - I can see some points up ahead.
0:05:10 > 0:05:13If we can change them, then we'll be back on course.
0:05:13 > 0:05:15So we just have to fetch the key.
0:05:15 > 0:05:18All right. This is sounding hopeful.
0:05:18 > 0:05:21My granddad showed me...once.
0:05:23 > 0:05:26- The key should be in the guard's van.- What's happening?
0:05:26 > 0:05:29Jeff, can I have a word?
0:05:29 > 0:05:31Got a little local difficulty.
0:05:31 > 0:05:33We'll talk later, Tee. Chill out.
0:05:33 > 0:05:35We're going to help.
0:05:36 > 0:05:37The key should be at the back.
0:05:42 > 0:05:44The doors are locked.
0:05:48 > 0:05:49They're watching us.
0:05:49 > 0:05:53- Oh, please, someone shut her up. - We need to smash these open.
0:05:53 > 0:05:55I'll get the tools.
0:05:55 > 0:05:59- They're open.- Jordan. Come on, Jordan, they're opening.
0:06:01 > 0:06:04The hospital's got its own emergency power supply.
0:06:04 > 0:06:06Where do we go to get the insulin?
0:06:06 > 0:06:07Pharmacy - that's it!
0:06:07 > 0:06:10- Look, get Ami on the bed. - I've found the switch.
0:06:10 > 0:06:12Help lift his legs up.
0:06:12 > 0:06:15Jordan, get on the bed. Look after Ami. Sadiq, unlock the wheels.
0:06:18 > 0:06:21Sadiq, what have you done? Stop it.
0:06:21 > 0:06:23- I'm trying.- Stop it.
0:06:23 > 0:06:26- I'm trying. I don't know what to do. - Stop it now.
0:06:26 > 0:06:28- This is only an emergency. - I don't work in a hospital.
0:06:28 > 0:06:32- What do you want me to do? - You can't even drive a bed.
0:06:32 > 0:06:34OK, go. Go!
0:06:35 > 0:06:37Come on.
0:06:37 > 0:06:39Reese, get behind me.
0:06:41 > 0:06:45- I've gone blind. - The generator must have died.
0:06:45 > 0:06:47Slow down! Watch out!
0:06:56 > 0:06:59Hey, come on, Ami needs his insulin. Look how pale he is now.
0:06:59 > 0:07:00Quick.
0:07:00 > 0:07:03Come on.
0:07:03 > 0:07:05Go left.
0:07:07 > 0:07:10Find the insulin.
0:07:18 > 0:07:21Over here.
0:07:21 > 0:07:24Ami has to keep his insulin cool in a flask. That's it, Jordie.
0:07:24 > 0:07:27Come on, let's go.
0:07:29 > 0:07:30Syringe?
0:07:30 > 0:07:32Here.
0:07:32 > 0:07:34Reese, roll up his sleeve.
0:07:34 > 0:07:37His blood-sugar levels are sky high.
0:07:39 > 0:07:43Is it like squash? Do you have to add water to make it less strong?
0:07:43 > 0:07:46Shut up, Reese.
0:07:48 > 0:07:51She's right. Give him that and you'll kill him.
0:07:51 > 0:07:55The dose is 10 mils at 0.05 molar solution.
0:07:55 > 0:07:59This is 0.5. Didn't you ever do decimals at school?
0:08:02 > 0:08:06Wait. Who are you? How do we know we can trust you?
0:08:06 > 0:08:08You don't. Got a better idea?
0:08:11 > 0:08:12- What's your friend's name?- Ami.
0:08:12 > 0:08:14Ami...
0:08:14 > 0:08:18Ami, can you hear me? Ami...
0:08:25 > 0:08:27What's going on?
0:08:27 > 0:08:30I'm thirsty.
0:08:30 > 0:08:32We thought you were going to die.
0:08:33 > 0:08:36What, me? Nah.
0:08:36 > 0:08:38Here, take these.
0:08:38 > 0:08:42You need to rehydrate Ami, so plenty of water. But he'll be fine.
0:08:42 > 0:08:43You need to go. You must leave
0:08:43 > 0:08:46straightaway. It's so important. Do you understand?
0:08:46 > 0:08:50And don't touch anything on the way out, especially the generator.
0:08:52 > 0:08:54Hey! Thank you.
0:08:54 > 0:08:58You heard what she said. Come on.
0:08:58 > 0:09:01And don't forget your injections again.
0:09:01 > 0:09:02Come on, guys.
0:09:05 > 0:09:08They're still watching us.
0:09:08 > 0:09:10Who is? Tell me.
0:09:12 > 0:09:16You know that I hate you.
0:09:16 > 0:09:18I hate you too.
0:09:26 > 0:09:31- Have you done it yet?- Just keep a lookout for any oncoming trains.
0:09:31 > 0:09:32Stay on the platform.
0:09:32 > 0:09:36Don't want no live jive bunnies jumping on the track.
0:09:36 > 0:09:40You know Tia's convinced herself she's on a one way ticket
0:09:40 > 0:09:43out of this dimension at midnight and you don't seem fussed.
0:09:43 > 0:09:46It's my way, Callum.
0:09:46 > 0:09:48T knows that. She's all intense.
0:09:48 > 0:09:51I'm light, bright, no worries.
0:09:51 > 0:09:54- You're talking like you're in a relationship.- We are.
0:09:54 > 0:09:56Kind of.
0:09:56 > 0:09:58Set up home, left home,
0:09:58 > 0:10:02went on the road...by steam train.
0:10:02 > 0:10:05Wow. Life's good.
0:10:07 > 0:10:09Look. That's shifting it.
0:10:09 > 0:10:12Jeffrey, you know it's not the real deal.
0:10:12 > 0:10:13If you want Tia to be your girl,
0:10:13 > 0:10:16- you'd better get a move on. - Why? You're not...?
0:10:16 > 0:10:19Oh, come on. Only got eyes for clever Kat.
0:10:19 > 0:10:21What I'm trying to say is, it's not just the adults
0:10:21 > 0:10:25- we're bringing back, is it? It's the competition.- Competition?
0:10:25 > 0:10:28Don't get me wrong, I think you're cool. But will she?
0:10:28 > 0:10:30Like, when all the older lads return?
0:10:30 > 0:10:34- Full steam ahead! - The steam pressure's dropping.
0:10:34 > 0:10:35Fill up the fire box!
0:10:35 > 0:10:37- With what?- Eh...coal?
0:10:37 > 0:10:41Errr! It's all gone.
0:10:41 > 0:10:43It's not our fault!
0:10:43 > 0:10:46You took so long tinkering trackside!
0:10:46 > 0:10:49We've lost her. There's no way to get her going again without fuel.
0:10:49 > 0:10:53Let's see if we can find some coal in that village.
0:10:53 > 0:10:54Yeah, let's.
0:10:54 > 0:10:57- Has anyone got a wheelbarrow? - Good idea!
0:10:57 > 0:10:59Let's go in the morning. It'll be dark soon
0:10:59 > 0:11:02- and things'll look better when we've had a good sleep.- Yeah.
0:11:02 > 0:11:05Let's hope Tia feels the same way.
0:11:16 > 0:11:17Let's just crash here.
0:11:17 > 0:11:19There's plenty of beds.
0:11:19 > 0:11:22You heard Flo Nightingale! We're going!
0:11:22 > 0:11:27Everyone that wants to stay the night, vote now!
0:11:28 > 0:11:31- RUN!- GET THEM!- Go. Go. Go! - Back to the entrance.- Hurry!
0:11:31 > 0:11:32- Which way?!- This way!
0:11:32 > 0:11:34- Come on! This way!- Come on!
0:11:34 > 0:11:36Hurry! Get to the van!
0:11:38 > 0:11:40That's it.
0:11:44 > 0:11:47Ami! Where's Ami?
0:11:47 > 0:11:49You left Ami behind!
0:13:01 > 0:13:02Jed.
0:13:02 > 0:13:04Beth.
0:13:06 > 0:13:09- You know what we've got to do, don't ya?- No, please.
0:13:09 > 0:13:11Not my brother, not Kyle, please.
0:13:11 > 0:13:15And when I've dealt with him I'll go looking for your little friend, Ami.
0:13:15 > 0:13:16Come on.
0:13:34 > 0:13:36I've rebooted the main circuits
0:13:36 > 0:13:38and I still don't think it's going to be enough.
0:13:38 > 0:13:41- Have you been round all the others wards yet?- No.
0:13:41 > 0:13:43You need to get to it immediately.
0:13:43 > 0:13:45Equipment might still be running on automatic.
0:13:45 > 0:13:47They all need switching off.
0:13:57 > 0:14:00You know what will happen if you slip up again, don't you?
0:14:00 > 0:14:02Yes, Jed. You can trust me.
0:14:07 > 0:14:08- Let's go.- We've got to go back in.
0:14:08 > 0:14:11Back in there? With them?
0:14:11 > 0:14:14The girl who gave me insulin is in huge trouble for letting us in.
0:14:14 > 0:14:17- That kid with the crutches is going to kill her brother.- Kill him?
0:14:17 > 0:14:20- Why?- I don't know! You saw him!
0:14:20 > 0:14:23- Does he need a reason? - It's way too dangerous.
0:14:23 > 0:14:27But she saved my life. I'd be dead if it wasn't for her.
0:14:27 > 0:14:29I'm going in.
0:14:29 > 0:14:30With or without you.
0:14:41 > 0:14:44It's working. She's watching!
0:14:44 > 0:14:46I TOLD you.
0:15:08 > 0:15:09In here!
0:15:17 > 0:15:21- We're going in. - In and out, yeah?- Well, obviously.
0:15:21 > 0:15:23You two quite finished?
0:15:32 > 0:15:34- Come on. - No! No stop!- It's all right, Beth.
0:15:34 > 0:15:37- Trust me! - Leave me along. What are you doing?
0:15:37 > 0:15:39We're trying to save your brother.
0:15:39 > 0:15:42I don't need to be rescued. My brother's in there!
0:15:42 > 0:15:43Follow me.
0:15:53 > 0:15:54Babies?
0:15:54 > 0:15:57This is my brother, Kyle.
0:15:57 > 0:16:00- He's just a baby. - What are they doing here?
0:16:00 > 0:16:01They want to save the babies.
0:16:01 > 0:16:04How? We've had to switch off Kyle's incubator!
0:16:04 > 0:16:06Please tell us what's going on.
0:16:06 > 0:16:08You messed with the generator!
0:16:08 > 0:16:10We'd been rationing the fuel, thousands of gallons
0:16:10 > 0:16:14in reserve and then you went and fired up the whole hospital!
0:16:14 > 0:16:18All the lights, all the machines, on every ward, on every floor.
0:16:18 > 0:16:20You plunged us into a life and death emergency.
0:16:20 > 0:16:22I thought you were going to hurt Kyle.
0:16:22 > 0:16:27Hurt him? No, we had to switch off an incubator.
0:16:27 > 0:16:31And since I was so angry at Beth, I decided it had to be Kyle's.
0:16:31 > 0:16:35I didn't want to let him die, so he's taking his chances in there
0:16:35 > 0:16:38with my little sister Ellie.
0:16:38 > 0:16:40Look. If you don't find a replacement
0:16:40 > 0:16:45fuel for the thousands of gallons you wasted, Kyle and Ellie will die.
0:16:45 > 0:16:47We can't stay, I'm sorry.
0:16:47 > 0:16:49We're on a Quest.
0:16:49 > 0:16:51To bring back the adults.
0:16:51 > 0:16:54I thought there was some kind of terrorist wipe-out.
0:16:54 > 0:16:58No. It was a scientific experiment, but it went wrong.
0:16:58 > 0:17:02The adults are fine. They're just in a parallel dimension.
0:17:02 > 0:17:05Invisible...but safe.
0:17:05 > 0:17:07So my mum's alive?
0:17:07 > 0:17:09Yeah, and so are we.
0:17:09 > 0:17:12- For the moment. - Unless we reunite the two
0:17:12 > 0:17:15dimensions quickly, all the power plants in our one
0:17:15 > 0:17:17will go, well, nuclear.
0:17:17 > 0:17:20We've got to think about the good of everyone.
0:17:20 > 0:17:22Do you have a sister?
0:17:22 > 0:17:24Yeah. A half sister.
0:17:24 > 0:17:26Frankie.
0:17:26 > 0:17:28And if it was Frankie in there...
0:17:28 > 0:17:31would you still want to save the planet and let her die?
0:17:31 > 0:17:33Or would you put her first?
0:17:33 > 0:17:36If that was Jeff in there,
0:17:36 > 0:17:39I'd be staying and helping, no matter what.
0:17:39 > 0:17:41We can do both.
0:17:41 > 0:17:44- Reese, if this is another one of your performances...- It's not.
0:17:44 > 0:17:47We can get fuel for the Hospital
0:17:47 > 0:17:49and get on with the Quest.
0:17:49 > 0:17:52- I know how. Don't worry. - It's getting darker.
0:17:52 > 0:17:54Did you think of that?
0:17:54 > 0:17:57Absolutely. Can we stay here for the night,
0:17:57 > 0:18:00if we fix everything in the morning?
0:18:00 > 0:18:01Please.
0:18:03 > 0:18:06Thank you. Sorted.
0:18:14 > 0:18:17Want a cuddle?
0:18:17 > 0:18:21You've already given me your best necklace.
0:18:21 > 0:18:22What's going on?
0:18:22 > 0:18:26Nothing. I just wanted you to know how special you are
0:18:26 > 0:18:29and...how much I'm going to miss you.
0:18:29 > 0:18:32But when the adults come back, we'll still live next door.
0:18:32 > 0:18:35Like we always have done! BORING!
0:18:35 > 0:18:39Frankie! Bedtime.
0:18:39 > 0:18:41Frankie!
0:18:44 > 0:18:47I've heard it's your birthday tomorrow.
0:18:48 > 0:18:50You know it was a one off, don't you?
0:18:50 > 0:18:52The adults disappearing.
0:18:52 > 0:18:53Yeah, course I do.
0:18:55 > 0:18:57When you wake up, you'll still be here,
0:18:57 > 0:19:00with us, with me.
0:19:00 > 0:19:03You in your compartment and me in mine.
0:19:04 > 0:19:07Jeffrey...
0:19:08 > 0:19:12..you know how it is with us...
0:19:12 > 0:19:15- I just... I...- Night, T.
0:19:16 > 0:19:19Goodbye. I mean, goodnight.
0:19:21 > 0:19:24You know, if it were to happen,
0:19:24 > 0:19:28if you were to disappear, I'll take care of the kids.
0:19:28 > 0:19:30Look after them until their parents get back.
0:20:15 > 0:20:17'Jeffrey... I need to tell you something...
0:20:17 > 0:20:19'because I might never see you again.'
0:20:23 > 0:20:24'I love you.'
0:20:41 > 0:20:43'I love you.'
0:20:56 > 0:20:57Reese is right.
0:20:57 > 0:21:01There's enough fuel in that thing to power the hospital for a year.
0:21:04 > 0:21:07And you're sure you can do this, yeah?
0:21:07 > 0:21:09Trained gymnast.
0:21:09 > 0:21:14- Come here, doggie. Come on. - Who's a good boy! That's it.
0:21:14 > 0:21:19- That's it. Who's a good boy! - Where's she going?
0:21:19 > 0:21:22Err. I don't know. Come here.
0:21:22 > 0:21:26That's it. Yeah, well done.
0:21:26 > 0:21:27Yes, Ami, go for it.
0:21:27 > 0:21:29Come on, Ami. You can do it.
0:21:29 > 0:21:31That's way too dangerous.
0:21:31 > 0:21:34- That's it, that's it. - He's a trained gymnast.
0:21:38 > 0:21:41- Good boy. Who's a good boy. - That's it.
0:22:02 > 0:22:05- Ami!- Talk to us, mate.- You OK?!
0:22:05 > 0:22:07- Ami!- Ami, are you all right?!
0:22:22 > 0:22:26SHE TUTS
0:22:26 > 0:22:29Ami, just move slowly.
0:22:31 > 0:22:34SHE TUTS
0:22:34 > 0:22:37Looking for this?
0:22:45 > 0:22:49- Reese.- And on top of everything else she's a dog whisperer!
0:22:49 > 0:22:51And on top of being crazy and stupid, you mean.
0:22:51 > 0:22:54No-one should approach a strange dog like that!
0:22:55 > 0:22:59- What do I do?! - Ram it into gear and then floor it!
0:23:03 > 0:23:04Come on.
0:23:05 > 0:23:07- SHE SCREAMS - MY SHOE!
0:23:07 > 0:23:10Forget about your stupid shoe!
0:23:10 > 0:23:13- Go, Ami.- Go!
0:23:26 > 0:23:28He's a worse driver than Sadiq!
0:23:28 > 0:23:30Impossible!
0:23:38 > 0:23:42That's it. The hospital tanks are almost full.
0:24:30 > 0:24:34I'm still here! I'm alive! I'm 15 and nothing's happened.
0:24:34 > 0:24:39Happy birthday to me, happy birthday to me! That's my necklace.
0:24:39 > 0:24:45Ow! But you said it was a token of how special I was to you.
0:24:45 > 0:24:48That was yesterday when I thought things were going to be different,
0:24:48 > 0:24:51but they're not, they're the same as yesterday.
0:24:51 > 0:24:53- Where's Jeffrey?- With Callum.
0:24:54 > 0:24:56This baby's run out of fuel.
0:24:56 > 0:25:00We're going to need a leaner, greener mode of transportation.
0:25:02 > 0:25:05That doesn't look leaner to me.
0:25:11 > 0:25:12The note.
0:25:30 > 0:25:33Listen up, guys. I've been thinking about stuff and
0:25:33 > 0:25:36I reckon we need a new tribe leader for the final leg of the Quest.
0:25:36 > 0:25:41Someone who's smart, sussed and won't bottle it in a crisis.
0:25:42 > 0:25:44- Reese.- Ha.
0:25:47 > 0:25:50- Reese?- Reese is the one who's got something special.
0:25:50 > 0:25:53And not just the sixth sense stuff.
0:25:53 > 0:25:55She even saved the babies.
0:25:55 > 0:25:59- Yeah and saved Kat from overdosing Ami..- You're NOT serious.
0:25:59 > 0:26:03Actually it makes sense.
0:26:03 > 0:26:07Ever since the disappearance, Reese has never been wrong.
0:26:07 > 0:26:10Reese! Want to be tribe leader?
0:26:17 > 0:26:19Only if you get me a new pair of shoes!
0:26:23 > 0:26:26The last leg of the Quest, guys!
0:26:26 > 0:26:27Last four legs, you mean!
0:26:27 > 0:26:30One horsepower!
0:26:31 > 0:26:34This one's easier to feed.
0:26:34 > 0:26:37- So, you're still here, then.- Yeah.
0:26:37 > 0:26:39I feel a bit stupid.
0:26:39 > 0:26:42- Well, don't.- All the over the top stuff you do when you think
0:26:42 > 0:26:44you're never going to see someone again.
0:26:44 > 0:26:50- Like, notes...that kind of thing. - What note?
0:26:59 > 0:27:01Happy birthday, T.
0:27:15 > 0:27:16Great Quetzalcoatl.
0:27:16 > 0:27:19As foretold in our scriptures return to slay the minotaur.
0:27:19 > 0:27:22Hello. Is anybody there?
0:27:22 > 0:27:24SCREAMS, ALARM BLARES
0:27:26 > 0:27:30- Reese, no, that's live electricity! - Incapacitate them.
0:27:31 > 0:27:33Kat, look at the screen.
0:27:33 > 0:27:34Katherine.
0:27:38 > 0:27:39Daddy.
