0:00:02 > 0:00:04- Where are all the grown-ups? - The world is full of children.
0:00:04 > 0:00:06- What are we going to do? - Anything we like.
0:00:06 > 0:00:09You must travel to the Sparticle Project and realign
0:00:09 > 0:00:12- our dimension with your dimension. - Can't you see the energy?
0:00:14 > 0:00:15She's not crazy, Sadiq.
0:00:15 > 0:00:19I will help you all I can in your great and noble quest.
0:00:19 > 0:00:22Doomsday Dora left us a clue. It's a postcode.
0:00:50 > 0:00:53The National Physics Institute.
0:00:53 > 0:00:56The postcode exactly matches the one Doomsday Dora gave us.
0:00:56 > 0:00:57We need to break in.
0:00:59 > 0:01:01Stand back.
0:01:01 > 0:01:03CLANG!
0:01:03 > 0:01:07- That's never going to work. - Got a better idea?
0:01:07 > 0:01:08I'll get in there before you do.
0:01:08 > 0:01:10Ami, come on, round the back.
0:01:13 > 0:01:14Guys...
0:01:16 > 0:01:20And next to compete in the Olympic Wheelie Bin challenge,
0:01:20 > 0:01:24the reigning champion, me.
0:01:24 > 0:01:25Come on, Ami.
0:01:27 > 0:01:28Nice parking.
0:01:28 > 0:01:30That's it, Ami.
0:01:33 > 0:01:35Right, then.
0:01:37 > 0:01:39Cool. We're in.
0:01:40 > 0:01:42Told you we'd beat them.
0:01:42 > 0:01:44Power.
0:01:44 > 0:01:47Yeah. Must have its own generator.
0:01:47 > 0:01:51Hey, this is a giant cooling system. It's just what we need!
0:01:51 > 0:01:53It's a bit big for the Spartivan.
0:01:53 > 0:01:55We need to work out why Dora sent us here.
0:01:58 > 0:01:59And beat Sadiq to it.
0:01:59 > 0:02:01LIFT BELL DINGS
0:02:13 > 0:02:16- Wow.- What is this place?
0:02:16 > 0:02:19This is where they designed the Sparticle Project,
0:02:19 > 0:02:21and somewhere, probably beneath our feet,
0:02:21 > 0:02:23is that thing up there,
0:02:23 > 0:02:26a miniature version of the real particle collider
0:02:26 > 0:02:28that Dad built - the Sparticle Project.
0:02:28 > 0:02:30That's why Dora sent us here.
0:02:33 > 0:02:36- What is all this?- It's a simulator.
0:02:36 > 0:02:39I like simulators. I do them all.
0:02:39 > 0:02:43Flying planes, rally cars, rockets.
0:02:44 > 0:02:48Not so fast. Science is for the smart, the logical.
0:02:48 > 0:02:50- Not for kids.- But you're a kid.
0:02:50 > 0:02:52Yeah, on the outside.
0:02:52 > 0:02:55Today I'm going to learn how to drive the Sparticle Project
0:02:55 > 0:02:57on my own.
0:02:59 > 0:03:01With one assistant.
0:03:03 > 0:03:06That is totally and completely unfair.
0:03:06 > 0:03:10All I have to do is move this beam and...
0:03:10 > 0:03:11Yes!
0:03:14 > 0:03:18We overheated the van coming all this way. So what? You could play a game?
0:03:18 > 0:03:20It's a prototype, Sadiq.
0:03:20 > 0:03:22Just get the instruction manual and get out of here.
0:03:22 > 0:03:25There isn't one. It's trial and error.
0:03:25 > 0:03:29And I know that luminite doesn't mix with particle colliders.
0:03:30 > 0:03:32Can you look after this for me?
0:03:36 > 0:03:39How long is this going to take?
0:03:44 > 0:03:46What?! You've got to be joking.
0:03:46 > 0:03:48Oh, and you can do it faster?
0:03:48 > 0:03:49No. I want to get back on the road.
0:03:49 > 0:03:53- Go on, then. - Look, Kat, I tell you what.
0:03:53 > 0:03:56I'll go back and fix the van and the rest of us will get some food.
0:03:56 > 0:03:59When I'm good and ready to leave, I'll honk the Spartihorn
0:03:59 > 0:04:01and that's when playtime's over, all right?
0:04:04 > 0:04:06Or we leave without you.
0:04:13 > 0:04:14Let's begin.
0:04:16 > 0:04:20You always have to get one up on Kat.
0:04:20 > 0:04:21Mind your own business, Ami.
0:04:21 > 0:04:23Maybe instead of always arguing,
0:04:23 > 0:04:26you and Kat try working together for a change?
0:04:57 > 0:05:00Ah, I thought we said food only.
0:05:00 > 0:05:03- Those are flowers.- Sniff them.
0:05:07 > 0:05:09The hen house!
0:05:09 > 0:05:11The hen house has been smashed.
0:05:11 > 0:05:13Matilda's missing.
0:05:13 > 0:05:16Missing? Like, taken?
0:05:16 > 0:05:20OK, get the rest of the chickens back inside the hotel.
0:05:20 > 0:05:22- Good grief.- What a mess.
0:05:22 > 0:05:23Frankie, Frankie get her.
0:05:23 > 0:05:25Liam, fetch a box.
0:05:27 > 0:05:29ALARM BEEPS
0:05:31 > 0:05:34How am I supposed to do this?
0:05:34 > 0:05:36I do collisions, but wavy lines I do not get.
0:05:39 > 0:05:41- Can I help?- No. I can do it myself.
0:05:41 > 0:05:43Just go away. Go.
0:05:52 > 0:05:53Hey, guys, come and look in here.
0:05:53 > 0:05:57FLIES BUZZ
0:05:57 > 0:05:59Urgh! It's disgusting.
0:06:03 > 0:06:06Just mank.
0:06:06 > 0:06:09- These look all right. - You must be joking!
0:06:09 > 0:06:10Hey, Reese,
0:06:10 > 0:06:13how would you like to test your psychic powers?
0:06:17 > 0:06:18These are Xener cards.
0:06:18 > 0:06:21Five symbols -
0:06:21 > 0:06:26circle, square, star, wavy lines, cross.
0:06:26 > 0:06:28Kat gets to play Grand Theft Particle Physics
0:06:28 > 0:06:29and all we get is snap?
0:06:29 > 0:06:33Xener cards are used to test people's psychic abilities.
0:06:33 > 0:06:34So guess.
0:06:34 > 0:06:36Circle.
0:06:39 > 0:06:42On average, you should guess one in five right.
0:06:42 > 0:06:45So if Reese gets more than that, she has psychic powers.
0:06:45 > 0:06:47You're serious, aren't you?
0:07:00 > 0:07:04And this will detect any chicken thieves climbing the fence.
0:07:04 > 0:07:06This will be awesome.
0:07:06 > 0:07:11Oh, sorry. Didn't I say? Boys only.
0:07:11 > 0:07:14Too dangerous for girls.
0:07:14 > 0:07:16Argh! Ow!
0:07:16 > 0:07:17Clumsy me.
0:07:17 > 0:07:19Well, I am just a girl.
0:07:19 > 0:07:22- Frankie, ow!- We're going to give these thieving kids
0:07:22 > 0:07:24such a scare they'll never bother us again.
0:07:27 > 0:07:29Go on, then.
0:07:31 > 0:07:33Circle.
0:07:33 > 0:07:35Wavy lines.
0:07:35 > 0:07:38- Next?- Wavy lines.
0:07:38 > 0:07:40Star.
0:07:40 > 0:07:43Wavy lines.
0:07:44 > 0:07:46Wavy lines.
0:07:47 > 0:07:50I can see wavy lines.
0:07:51 > 0:07:53And finally?
0:07:53 > 0:07:54Square.
0:08:00 > 0:08:02ALARM BLARES
0:08:02 > 0:08:03CLATTERING
0:08:06 > 0:08:10- I think something went wrong. - Cards Reese guessed wrong, 25.
0:08:10 > 0:08:13Cards Reese guessed right, none.
0:08:13 > 0:08:16So, Jordan, what were you saying about psychic powers?
0:08:16 > 0:08:18- She did save us at the fairground. - No doubt about that.
0:08:18 > 0:08:22You're such idiots. Can't you see it's all a trick?
0:08:22 > 0:08:26It's what she does. I'm going to look for food or something useful.
0:08:30 > 0:08:32- Found anything?- Nothing.
0:08:34 > 0:08:37Hey, guys, in here!
0:08:41 > 0:08:43The cooling system.
0:08:43 > 0:08:45Cool!
0:08:45 > 0:08:47Get it? COOL.
0:08:49 > 0:08:51Help me move it.
0:08:52 > 0:08:54BEEPING
0:08:58 > 0:09:01"Warning. Close door now."
0:09:08 > 0:09:10The door!
0:09:10 > 0:09:12BEEPING CONTINUES
0:09:12 > 0:09:15"Security locked."
0:09:17 > 0:09:19"Cooling system activated."
0:09:21 > 0:09:23SHE GASPS
0:09:30 > 0:09:32- You idiot! - I don't think she can hear us.
0:09:32 > 0:09:35I can't hear you!
0:09:36 > 0:09:38Let me try.
0:09:38 > 0:09:41Reese, fetch Kat.
0:09:47 > 0:09:49Oh!
0:09:53 > 0:09:56The old oak door creaked eerily.
0:09:56 > 0:09:59It was only as she left that she realised.
0:09:59 > 0:10:02RATTLING AND BANGING FROM OUTSIDE
0:10:02 > 0:10:06Yeah, Frankie, really funny(!)
0:10:08 > 0:10:10It's an animal.
0:10:10 > 0:10:13- Where's the water gun? - You can't go out there.
0:10:13 > 0:10:15What if it's escaped from the zoo?
0:10:15 > 0:10:17What if it's a lion?
0:10:17 > 0:10:19It can smell dinner.
0:10:19 > 0:10:22It's going to eat us?
0:10:22 > 0:10:23No, OUR dinner!
0:10:26 > 0:10:28I said veggie, but you insisted on pepperoni.
0:10:32 > 0:10:33Argh!
0:10:38 > 0:10:40It's a fox.
0:10:40 > 0:10:43I wasn't scared, really.
0:10:45 > 0:10:48- Jeffrey, look. It's going inside. - Let's get after it.
0:10:48 > 0:10:50CHICKENS CLUCK
0:10:53 > 0:10:55Shoo!
0:11:07 > 0:11:09They're all right.
0:11:11 > 0:11:12I told you she was a prankster.
0:11:12 > 0:11:16Perhaps next time you'll believe me. She's dangerous!
0:11:18 > 0:11:19We just need to force the lock.
0:11:19 > 0:11:22Why's it so cold in here?
0:11:23 > 0:11:24Reese!
0:11:33 > 0:11:38- Let's try and break the glass. - It won't work. It's reinforced.
0:11:38 > 0:11:42But if there's a blow torch, maybe I could melt the lock.
0:11:42 > 0:11:45We need a faster solution than that.
0:11:45 > 0:11:46I'm going to the simulator room
0:11:46 > 0:11:48to see if there's something I can do there.
0:11:52 > 0:11:55Horrible fox.
0:11:55 > 0:11:56Our poor chickens.
0:11:56 > 0:12:01This is how it is now. Every person and fox for themselves.
0:12:01 > 0:12:03Eggs are good for trading as well as eating.
0:12:03 > 0:12:05We need the chickens.
0:12:05 > 0:12:08We'll trap the fox. Set it free in the park.
0:12:08 > 0:12:10It'll come straight back.
0:12:10 > 0:12:12All wild animals go back to their territory,
0:12:12 > 0:12:15whether they're lions or foxes, even if you dump them miles away.
0:12:15 > 0:12:19And how would we move it? It's a wild animal, not a fluffy toy.
0:12:19 > 0:12:21It's not going to come without making a noise.
0:12:21 > 0:12:23So what's your solution?
0:12:26 > 0:12:28I think we have to...kill it.
0:12:28 > 0:12:31- No way.- You can't do that!
0:12:31 > 0:12:33It's just hungry.
0:12:33 > 0:12:35You two should be in bed.
0:12:35 > 0:12:37We'll talk about this in the morning.
0:12:37 > 0:12:39Pity it wasn't a lion.
0:12:39 > 0:12:42You wouldn't be talking about killing it then.
0:12:42 > 0:12:44I'm going to give this to the fox.
0:12:44 > 0:12:46Get to bed.
0:12:57 > 0:13:01Reese, use your powers to open the door.
0:13:25 > 0:13:27No!
0:13:46 > 0:13:49- Tell her to stop staring. - She's focusing her powers.
0:13:49 > 0:13:52- She can't open the door. - Just because you don't believe.
0:13:52 > 0:13:54Grow up, Jordan. There are no magic powers.
0:13:54 > 0:13:56No one's going to make everything right.
0:13:56 > 0:13:58Kat and Sadiq will get us out.
0:13:58 > 0:14:02Will they? They're probably somewhere having another argument.
0:14:06 > 0:14:10Let's use our body warmth. I saw it in a survival programme.
0:14:10 > 0:14:12- Come on, in a cuddle. - I'm not cuddling you.
0:14:12 > 0:14:14I'd rather freeze to death.
0:14:14 > 0:14:15I meant huddle.
0:14:15 > 0:14:19And I wouldn't make any jokes about freezing to death if I were you.
0:14:32 > 0:14:34Here. Wrap this around you.
0:14:36 > 0:14:40- There's nothing else left. - You keep it.
0:14:43 > 0:14:46I bet they're doing the best they can, you know.
0:14:46 > 0:14:49Yeah, I guess we're all just kids.
0:14:54 > 0:14:56Hey, where's Reese?
0:14:56 > 0:14:59Given up and gone to sleep, I bet.
0:14:59 > 0:15:00She doesn't care.
0:15:04 > 0:15:08You're not going to save them, are you? How? By blowing the place up?
0:15:08 > 0:15:09Oh, I'm going to save the world.
0:15:09 > 0:15:13Half of our tribe are stuck in a giant fridge. Nice one(!)
0:15:13 > 0:15:17- You were supposed to be in charge while I...- Played stupid games?
0:15:17 > 0:15:20Oh, Kat, come on. There must be a way.
0:15:20 > 0:15:23Yeah, sabotage the cooling system.
0:15:23 > 0:15:25Crawl into a pipe and break the mechanism.
0:15:25 > 0:15:28But inside the pipe is way below freezing.
0:15:28 > 0:15:31Anyone that went in there wouldn't come out.
0:15:31 > 0:15:33- I only did what the sign said. - Reese?
0:15:33 > 0:15:38The sign on the door said close door now, close door now.
0:15:38 > 0:15:41When was this?
0:15:41 > 0:15:43After we left you in here.
0:15:43 > 0:15:46I got impatient so I boosted the power.
0:15:46 > 0:15:49So the cooling system must have gone into overdrive. It was me.
0:15:49 > 0:15:51I locked them in there.
0:15:51 > 0:15:54But you didn't mean to, right?
0:15:54 > 0:15:57The thing is, can you stop it?
0:15:58 > 0:16:00Yeah.
0:16:00 > 0:16:03Yeah, I'll abort the simulation. It's useless anyway.
0:16:03 > 0:16:06There's no need to wait for anything to cool down.
0:16:06 > 0:16:09The door should just unlock.
0:16:09 > 0:16:11Go, Sadiq. I'm going to shut this down.
0:16:24 > 0:16:25It's all right.
0:16:25 > 0:16:28It's shutting down.
0:16:28 > 0:16:30Maybe now I can close the main frame.
0:16:32 > 0:16:34We've sorted it. Don't worry.
0:16:42 > 0:16:44Let's huddle together.
0:16:55 > 0:16:58The door didn't open. They're frosted.
0:17:01 > 0:17:04Time till shut down approximately six hours!
0:17:04 > 0:17:07They're not going to last six hours. No way!
0:17:09 > 0:17:11Well?
0:17:13 > 0:17:15I used to like being cold.
0:17:17 > 0:17:19Going out in the snow,
0:17:20 > 0:17:23coming in all wet
0:17:23 > 0:17:26and Mum making us cocoa.
0:17:26 > 0:17:29I never want to see snow again.
0:17:29 > 0:17:31I'm moving to the Bahamas.
0:17:31 > 0:17:33I went to the Bahamas
0:17:33 > 0:17:36- and got sunburn.- Oh, sunburn!
0:17:36 > 0:17:38HANDLE RATTLES
0:17:41 > 0:17:43Ami, get everyone on their feet.
0:17:44 > 0:17:47Holly, wake up.
0:17:47 > 0:17:48Wake up.
0:17:48 > 0:17:50Keep moving.
0:17:50 > 0:17:52Don't sit down, don't...
0:17:54 > 0:17:58I can sort this. Just, just hold on.
0:17:58 > 0:18:00Please.
0:18:12 > 0:18:14Come on, please work.
0:18:29 > 0:18:33AIR WHOOSHES FROM VENT
0:18:36 > 0:18:37Where's Sadiq?
0:18:45 > 0:18:46He's in the pipe.
0:18:53 > 0:18:56You said he'll freeze to death.
0:18:56 > 0:18:59Sadiq! Sadiq! Sadiq!
0:18:59 > 0:19:02He won't be able to hear you. The helium will be deafening him.
0:19:02 > 0:19:04There's nothing else we can do,
0:19:04 > 0:19:06except go to the others and wait. OK?
0:19:41 > 0:19:43ICE CRACKLES
0:19:52 > 0:19:55I knew he was going to do something stupid.
0:19:55 > 0:19:59It's not stupid if it gets us out.
0:19:59 > 0:20:04Don't you get it? He's putting his own life on the line for us.
0:20:11 > 0:20:13"Save..."
0:20:14 > 0:20:16Save?
0:20:17 > 0:20:18Save Sadiq?
0:20:34 > 0:20:37Jordan? Got him!
0:20:37 > 0:20:39Jordan!
0:20:39 > 0:20:41Jordan!
0:20:52 > 0:20:54CLATTERING
0:20:54 > 0:20:57FAN CLATTERS AND BANGS
0:21:02 > 0:21:05EXPLOSION RINGS OUT
0:21:09 > 0:21:11Come on. Get up.
0:21:11 > 0:21:14Get up. Jordan, get up. You all right?
0:21:14 > 0:21:16- I'm all right, go on. - Here, put this on.
0:21:18 > 0:21:20- So cold.- Take this, Holly.
0:22:06 > 0:22:09- ALL:- Sadiq! Where are you?
0:22:09 > 0:22:13- ALL:- Sadiq!- Hey! Bang on the pipes. The one he's in will sound dull.
0:22:13 > 0:22:15If he's not, it will sound tinny.
0:22:19 > 0:22:20Sadiq. Where are you?
0:22:20 > 0:22:23Sadiq! Sadiq!
0:22:23 > 0:22:25Are you in there? Sadiq!
0:22:25 > 0:22:28Sadiq! Sadiq! Where are you?
0:22:28 > 0:22:30Sadiq!
0:22:30 > 0:22:33- Sadiq!- Stop shouting!
0:22:40 > 0:22:41Sadiq!
0:22:41 > 0:22:43I think he's here. I think he's here!
0:22:43 > 0:22:45Jordan.
0:22:56 > 0:22:58Get him out!
0:22:58 > 0:23:00Help me!
0:23:05 > 0:23:07- Is he dead?- You all right?
0:23:07 > 0:23:09Sit him up.
0:23:11 > 0:23:13Get the coat on him.
0:23:17 > 0:23:19You OK?
0:23:19 > 0:23:21Warm him up. Come on!
0:23:24 > 0:23:28- You OK? - Chill out.
0:23:33 > 0:23:36- It's not been touched.- Frankie.
0:23:36 > 0:23:37What?
0:23:37 > 0:23:41It's Tia and Jeffrey last night.
0:23:41 > 0:23:45They've taken away the fox in that bag and killed him!
0:23:52 > 0:23:55Where is Mr Fox?
0:23:55 > 0:23:58Mr Fox is very much alive and looking for a new home.
0:23:58 > 0:24:02I thought if a bigger animal moves into a fox's territory,
0:24:02 > 0:24:04what will the fox do?
0:24:04 > 0:24:07- Give up and move out. - We don't have a bigger animal.
0:24:07 > 0:24:09Yeah, but thanks to the zoo we do have some...
0:24:09 > 0:24:12- lion poo.- Oh!
0:24:12 > 0:24:15They used to sell it for keeping cats off people's gardens.
0:24:15 > 0:24:17Soon as we spread it around the yard,
0:24:17 > 0:24:19Mr Fox thought a lion had moved in and left.
0:24:19 > 0:24:21We won't have any more fox trouble.
0:24:21 > 0:24:23We won't have any more visitors either.
0:24:26 > 0:24:28What you got there, Jeff?
0:24:28 > 0:24:30Um, Tia, I've got you some...
0:24:30 > 0:24:34Coriander! Thanks, Jeff, perfect for the soup.
0:24:38 > 0:24:42- Kat, it's overheating.- There's still time to try something.
0:24:42 > 0:24:45Tapping on those pipes to find Sadiq gave me an idea.
0:24:45 > 0:24:48You know what? I'm so over this.
0:24:48 > 0:24:53Please, Jordan. I think I finally understand why Dora sent us here.
0:24:53 > 0:24:54Take these.
0:24:59 > 0:25:02The simulation is about tuning all lines onto the same frequency
0:25:02 > 0:25:05on all computer screens, not just mine, so they resonate as one.
0:25:07 > 0:25:10Hurry, I need to see if this works.
0:25:17 > 0:25:20I think I've done it.
0:25:22 > 0:25:24I have, I've...
0:25:24 > 0:25:27We've done it.
0:25:27 > 0:25:29All three lines are one and everything's realigned.
0:25:29 > 0:25:34- So you know how to fix things at the Sparticle Project?- Kind of.
0:25:34 > 0:25:36So, you don't?
0:25:36 > 0:25:39Yes, she does. I mean, she knows enough.
0:25:39 > 0:25:41The thing about simulators
0:25:41 > 0:25:45is that they train you to deal with any situation or emergency.
0:25:45 > 0:25:47And we just had one of those.
0:25:47 > 0:25:50I get it. Doomsday Dora wrote this simulation
0:25:50 > 0:25:53so we can learn how to bring back the adults.
0:25:53 > 0:25:58The only way we can make the two worlds one is if we pull together.
0:25:58 > 0:26:02I hope you're right, guys, cos we sure have blown up this baby.
0:26:21 > 0:26:24I can see a...
0:26:24 > 0:26:27diamond, circle,
0:26:27 > 0:26:29square and wormhole.
0:26:29 > 0:26:31Do you want to play a game of snap?
0:26:31 > 0:26:33It's a game we can play together.
0:26:33 > 0:26:36Go on, then.
0:26:36 > 0:26:40- Anything to take my mind off Dad's driving.- Me too.- Count me in.
0:26:40 > 0:26:43- Ready?- Brace yourself for take-off, everyone.
0:26:45 > 0:26:49Who's ready to realign the worlds so we can bring back the taxi drivers?
0:26:49 > 0:26:52All right. Seat belts on, people.
0:26:57 > 0:27:00GEAR BOX GRATES
0:27:16 > 0:27:18- They're coming.- Attack!
0:27:23 > 0:27:25Urgh. Manure. Run!
0:27:29 > 0:27:32Holly, he's left the tribe. He's made his choice.
0:27:32 > 0:27:35- We need the lock key. - Confess or live to regret it.
0:27:35 > 0:27:38- What key?- Argh!
