0:00:00 > 0:00:03My father's Henry Barker, the physicist.
0:00:03 > 0:00:06The machine went a bit wrong.
0:00:06 > 0:00:08Sparticle Project is in Grandad's mine?
0:00:08 > 0:00:14Luminite magnifies energy, light, heat, sound, the lot.
0:00:14 > 0:00:17You must travel to the Sparticle Project and bring the adults back.
0:00:17 > 0:00:19Destination...Yorkshire Moors.
0:00:19 > 0:00:24We've got Prof Barker's voice on Dictaphone. This should get you in.
0:00:24 > 0:00:25You need me to get the Dictaphone!
0:00:25 > 0:00:28- What's so special about it? - Special friendship.
0:00:28 > 0:00:32- I don't trust this new Callum.- I saw a ghost girl, she was see-through.
0:00:59 > 0:01:01We're getting near to Black Tor Mine.
0:01:03 > 0:01:05Whoa! Sadiq!
0:01:07 > 0:01:09The moles must be on steroids here.
0:01:13 > 0:01:16- What are you doing, Reese? - Protecting myself.
0:01:16 > 0:01:18Luminite sends me funny.
0:01:18 > 0:01:22And there's probably enough luminite in the Black Tor Mine to kill me.
0:01:24 > 0:01:28(Stop smiling, Holly. It's not good.)
0:01:28 > 0:01:32- How did she see that?- See what?
0:01:32 > 0:01:34Didn't you hear Reese say, "Stop smiling, Holly"?
0:01:36 > 0:01:38I warned you to stay out of my head.
0:01:42 > 0:01:45That's it. The Black Tor Mine!
0:01:45 > 0:01:49- We're at the Sparticle Project! - Yeah!- Yeah!
0:01:49 > 0:01:53You know realigning the world and bringing back the adults
0:01:53 > 0:01:57means the end of the Quest and the end of the Sparticles.
0:02:01 > 0:02:04I can't get my head round everything going back to how it was before.
0:02:04 > 0:02:08Me neither. One thing's for sure...
0:02:08 > 0:02:10I'm going to be a horticulturist.
0:02:10 > 0:02:13Oh. That's great.
0:02:13 > 0:02:16When are we getting to the Sparticle Project?
0:02:16 > 0:02:19Never at this rate, we're lost.
0:02:26 > 0:02:28It's a road trap.
0:02:28 > 0:02:30These mole hills have been deliberately spiked.
0:02:30 > 0:02:33Hey, that's luminite!
0:02:33 > 0:02:35We must be close to the Black Tor Mine!
0:02:35 > 0:02:37The cart's wrecked.
0:02:37 > 0:02:40You make your way by horse and I'll go on ahead.
0:02:40 > 0:02:43- Kat needs this Dictaphone or it's the end of the Quest.- Hang on!
0:02:43 > 0:02:46- But which way?- Follow the luminite!
0:02:57 > 0:02:59Come on, let's take a look.
0:02:59 > 0:03:01You go on Sadiq, I'll lock up.
0:03:03 > 0:03:05You sure this is the Sparticle Project?
0:03:05 > 0:03:08It's the Black Tor Mine, so yeah.
0:03:08 > 0:03:10I can't believe we've finally made it.
0:03:10 > 0:03:12And that was total rubbish about the voice activated door!
0:03:12 > 0:03:15I've seen higher tech doors on a phone box.
0:03:15 > 0:03:18This is pretty weird.
0:03:18 > 0:03:20Just as well we don't need Callum!
0:03:20 > 0:03:22Cos I...
0:03:22 > 0:03:25- don't see him.- He'll be here.
0:03:25 > 0:03:27Doubt it.
0:03:27 > 0:03:30Me and you.
0:03:30 > 0:03:31We do all the hard stuff!
0:03:31 > 0:03:37- But since when can moles dig through concrete?- Luminite.
0:03:37 > 0:03:39Where's Reese?
0:03:39 > 0:03:41Probably run away as per usual.
0:04:01 > 0:04:03This thing's locked, Sadiq.
0:04:03 > 0:04:04Press the bell.
0:04:04 > 0:04:07BELL RINGS
0:04:12 > 0:04:14Yes?
0:04:14 > 0:04:16Er. Is this the Sparticle Project?
0:04:16 > 0:04:18No. You must have the wrong address.
0:04:18 > 0:04:20Whoa. Not so fast.
0:04:20 > 0:04:24- Let us in.- No-one enters without the permission of our Tribe Leader.
0:04:24 > 0:04:28Megan of the Mystic Moles. I'm Mungo Mole.
0:04:28 > 0:04:30Listen...Mole.
0:04:30 > 0:04:34- Take me to Mr Toad. - You're clearly not Believers.
0:04:34 > 0:04:35Moles!
0:04:39 > 0:04:42Get a load of this lot!
0:04:55 > 0:04:57DOOR UNLOCKS
0:05:03 > 0:05:04Oh, no!
0:05:06 > 0:05:08Holly!
0:05:08 > 0:05:10Great Quetzacoatl!
0:05:10 > 0:05:15In your mystical armour as has been foretold, come to slay the Minotaur!
0:05:15 > 0:05:22- Look, it's Quetzacoatl!- At last, we shall be free of the Minotaur.
0:05:22 > 0:05:25- Right, Holly. - Excuse me, but a Minotaur?
0:05:25 > 0:05:28A man-eating bull-headed monster.
0:05:28 > 0:05:30- Yeah, I know what it is. But it's not real.- Yes, it is.
0:05:30 > 0:05:32And it lives deep in our mine.
0:05:32 > 0:05:35Come with us, our saviours. Come on.
0:05:36 > 0:05:38Er, Sadiq,
0:05:38 > 0:05:40I'm just going to wait for Callum. Just in case.
0:05:40 > 0:05:43Give it up, Kat.
0:05:43 > 0:05:45We're in, aren't we?
0:05:49 > 0:05:54I know you locked me in the van, Holly. But you won't stop the Quest.
0:06:01 > 0:06:04Wow. This is jam-packed with luminite.
0:06:04 > 0:06:06Are you all right, Reese?
0:06:06 > 0:06:09As long as I wear this armour I'm safe from luminite.
0:06:20 > 0:06:24Our Leader, The Very Mystical Megan Mole.
0:06:24 > 0:06:27Quetzacoatl. As foretold in your Scriptures.
0:06:27 > 0:06:30He has come to slay the Minotaur and allow us through the Silver Door.
0:06:30 > 0:06:31Silver door?
0:06:31 > 0:06:33That's the voice-activated door.
0:06:33 > 0:06:36Yeah, but without the Dictaphone, we're stuck.
0:06:37 > 0:06:40I come in peace.
0:06:40 > 0:06:42Shiny, shiny!
0:06:43 > 0:06:45I don't believe this.
0:06:45 > 0:06:47Have you seen this minotaur?
0:06:47 > 0:06:50No. But it consumed all our parents.
0:06:50 > 0:06:53Megan Mole has explained everything.
0:06:53 > 0:06:56No-one has made it alive through the Red Labyrinth
0:06:56 > 0:07:00to the Minotaur's Lair, let alone through the Silver Door.
0:07:26 > 0:07:28Come on.
0:07:30 > 0:07:35If you are Quetzacoatl you'll know the code of the Aztec Warriors.
0:07:35 > 0:07:37Sparticle Project.
0:07:37 > 0:07:39That is not correct.
0:07:39 > 0:07:42But I can hear the particle beam going round the Collider.
0:07:42 > 0:07:46I can hear the Sparticle Project. It's behind you.
0:07:50 > 0:07:54And I'm rather more interested in what is behind you.
0:08:01 > 0:08:03An imposter! Incapacitate them!
0:08:06 > 0:08:09All those who disobey will be used as offerings.
0:08:09 > 0:08:11To the Minotaur.
0:08:20 > 0:08:23I was expecting something a bit more... spartacular.
0:08:23 > 0:08:25Where are the Questers?
0:08:25 > 0:08:28That won't be loud enough.
0:08:28 > 0:08:31It will if I use the luminite to boost the sound.
0:08:31 > 0:08:34Hello? Is anybody there?
0:08:36 > 0:08:38Hello? Is anybody there?
0:08:38 > 0:08:40It's the minotaur!
0:08:44 > 0:08:46Stop!
0:08:46 > 0:08:49Stop!
0:08:50 > 0:08:52It's the Minotaur!
0:08:54 > 0:08:55It can't be.
0:08:55 > 0:08:58It is! Kat!
0:09:02 > 0:09:05My bro? Jordan.
0:09:05 > 0:09:07Driving everyone crackers!
0:09:07 > 0:09:09C'mon. C'mon then.
0:09:18 > 0:09:20THEY ALL TALK AT ONCE
0:09:29 > 0:09:32OK, Sparticles! Tribe Sparticles, shut it!
0:09:32 > 0:09:35- Be quiet! - We're all here for same reason.
0:09:35 > 0:09:37And that's so we can bring back our parents.
0:09:37 > 0:09:40So...
0:09:40 > 0:09:44Callum, have you the key to the door, the Dictaphone?
0:09:46 > 0:09:49Gave my word.
0:09:49 > 0:09:52After all that let's just hope it works!
0:09:52 > 0:09:54I can't bear the luminite.
0:09:54 > 0:09:58OK, Reese, so let's get out of this mine and into the Sparticle Project.
0:09:58 > 0:10:00Come on, this way.
0:10:13 > 0:10:14Please work.
0:10:17 > 0:10:21'To the Sparticle Project to prepare for the switching on. Henry Barker.'
0:10:23 > 0:10:26BEEPING
0:10:26 > 0:10:29It's not working.
0:10:29 > 0:10:32Give it time. It's thinking.
0:10:32 > 0:10:35Who has a conversation with a door? Just play the name bit, come on!
0:10:35 > 0:10:38Holly's right.
0:10:38 > 0:10:40Rewind it.
0:10:44 > 0:10:46'Henry Barker.'
0:10:48 > 0:10:50Welcome, Professor Barker
0:10:50 > 0:10:52and may the Photons be with you.
0:10:52 > 0:10:55Dad's little idea of a joke.
0:10:56 > 0:11:00Like a Particle Collider in a mine full of energy magnifying luminite?
0:11:00 > 0:11:02That's funny.
0:11:07 > 0:11:09There goes trouble.
0:11:09 > 0:11:10Quick. The door's closing!
0:11:20 > 0:11:22We're in!
0:11:23 > 0:11:25We're in the Sparticle Project.
0:11:25 > 0:11:27Yee-hah!
0:11:27 > 0:11:30When you press a button or switch something on
0:11:30 > 0:11:32it starts off a chain of events.
0:11:32 > 0:11:34That's what scientists did. Here!
0:11:34 > 0:11:36I'm scared.
0:11:37 > 0:11:40Focus on something straight ahead of you, it's better.
0:11:40 > 0:11:42And that way it's not scary.
0:11:42 > 0:11:46Everybody fix on that. Let's head for the control room.
0:12:01 > 0:12:03Well, switch it off, then.
0:12:03 > 0:12:07- It's not as simple as that, Tia. - Why not, Kat?
0:12:07 > 0:12:12Switch off the Sparticle Project and the worlds realign. Simples.
0:12:12 > 0:12:15Frankie, I'm the pilot of a jumbo jet. I want to land.
0:12:15 > 0:12:18- Do I just "switch it off?"- No, silly!
0:12:18 > 0:12:22You'd drop out of the sky and crash, killing everybody horribly!
0:12:22 > 0:12:25Well. The Sparticle Project is a like a million jumbo jets.
0:12:25 > 0:12:28We need to reduce the machine's power
0:12:28 > 0:12:32slowly or just like that plane Frankie was talking about, we'll
0:12:32 > 0:12:34lose everyone on board.
0:12:34 > 0:12:36You mean the grown ups?
0:12:37 > 0:12:40This line is Us, and that's Them.
0:12:40 > 0:12:44Once the lines have merged together and stay together,
0:12:44 > 0:12:46we'll know we've done it.
0:12:46 > 0:12:49And if they don't?
0:12:49 > 0:12:53Then we wouldn't have brought back the adults.
0:12:53 > 0:12:54Simples.
0:13:01 > 0:13:03I'm losing speed control.
0:13:03 > 0:13:06- Feels like the brakes have failed! - They have.
0:13:06 > 0:13:08That's what the magnets do, control the beam and slow it down.
0:13:11 > 0:13:14Sabotage.
0:13:14 > 0:13:16- Mystic Meg.- I can handle that.
0:13:16 > 0:13:18Jeff, let's go find the magnet!
0:13:18 > 0:13:23- This isn't one of your botch jobs on the Spartivan, you need me!- And us!
0:13:23 > 0:13:27- Any volunteers for Pest Control?- Me! - Tia? We do everything together.
0:13:27 > 0:13:29You're not the only one thinking about their future.
0:13:29 > 0:13:31Happy horticulturing.
0:13:43 > 0:13:45Where is she?
0:13:45 > 0:13:48We need to find her, and fast!
0:13:50 > 0:13:52There she is!
0:14:02 > 0:14:06- She's getting away. - Not from me she isn't.
0:14:33 > 0:14:35I need Sadiq to get the Master Magnet back in the loop!
0:14:35 > 0:14:39The other magnets can't deal with the extra workload. It's overloading!
0:14:39 > 0:14:42'Energy overload.'
0:14:42 > 0:14:44Hurry, Sadiq!
0:14:44 > 0:14:47I need you to fix that magnet and now!
0:14:50 > 0:14:54- What's wrong with the magnet?- I don't know. Look for the broken bit!
0:15:01 > 0:15:03Don't get any closer or I'll drop it.
0:15:03 > 0:15:07- Why are you doing this? - It's obvious, isn't it?
0:15:07 > 0:15:10The Sparticle Project vaporised my mum and everyone else working here.
0:15:10 > 0:15:12We were living on site when it happened.
0:15:12 > 0:15:17So don't think I'm going to let you send me into oblivion. You STOP!
0:15:17 > 0:15:21- Don't! That module will bring your mum back.- I'm sick of make-believe.
0:15:21 > 0:15:24You're the one playing dress-ups. What's with the headgear?
0:15:24 > 0:15:26I had to cobble together history and myth and pretend
0:15:26 > 0:15:28the Sparticle Project was a Minotaur
0:15:28 > 0:15:32just to make it fun, to inspire the younger kids to help me.
0:15:32 > 0:15:36- Help you do what?- Protect child kind from another catastrophe.
0:15:36 > 0:15:39We've been guarding the door so no-one can mess with the machine.
0:15:39 > 0:15:41The machine is picking up speed.
0:15:41 > 0:15:44Without the master magnet I can't slow it down!
0:15:46 > 0:15:48The broken bit. It's here!
0:15:49 > 0:15:52- We've got to plug the gap! - What with?
0:15:52 > 0:15:54With this.
0:15:54 > 0:15:58If we can boost the magnet we can slow the machine down.
0:16:03 > 0:16:04They've fixed it.
0:16:06 > 0:16:10We're doing it... we're bringing the worlds together.
0:16:10 > 0:16:13The adults will be with us soon.
0:16:22 > 0:16:23Listen to us.
0:16:23 > 0:16:26We're going to bring back your mum.
0:16:26 > 0:16:30No. I don't believe your fairy story.
0:16:30 > 0:16:32No!
0:16:37 > 0:16:39I have to do something.
0:16:41 > 0:16:43Holly. Go after her.
0:16:43 > 0:16:46- No way. - What, so the adults don't come back
0:16:46 > 0:16:48because I was chasing after Reese?
0:16:57 > 0:16:59Dig your way out of this!
0:17:22 > 0:17:26What are you going to do? Hide? I thought this was your big moment.
0:17:26 > 0:17:28Hello, Muna.
0:17:28 > 0:17:31She's coming back! Muna!
0:17:39 > 0:17:42That's it, Muna, you're nearly with us.
0:17:47 > 0:17:48This is Muna.
0:17:48 > 0:17:51She saved you once, Holly. Remember, at the funfair?
0:17:54 > 0:17:57I've left the others holding the luminite in place.
0:17:57 > 0:18:00It's boosting the magnet.
0:18:00 > 0:18:02Kat?
0:18:02 > 0:18:06I've got an electrical problem now as well!
0:18:08 > 0:18:12This time we'll do it together. The worlds are realigning.
0:18:12 > 0:18:15You were closer, in limbo, caught between the two,
0:18:15 > 0:18:20but the adults are further away. They need our help.
0:18:20 > 0:18:23The cables are cut. We need to reconnect the power.
0:18:25 > 0:18:27Reese, no! That's live electricity.
0:18:27 > 0:18:29I can do it! It's my mission.
0:18:29 > 0:18:33From the moment I felt the Sparticle Project switching on
0:18:33 > 0:18:36I've been gaining new powers. Now I know why. (Muna, are you ready?)
0:18:36 > 0:18:39(Yes, but I'm not as strong as you.)
0:19:06 > 0:19:07Kat.
0:19:07 > 0:19:10Kat, look at the screen!
0:19:11 > 0:19:15You're doing it... the worlds are coming together!
0:19:16 > 0:19:18- MAN:- Katherine.
0:19:21 > 0:19:23Daddy.
0:19:37 > 0:19:38Mum!
0:19:38 > 0:19:42I missed you so much! I thought you were dead.
0:19:45 > 0:19:47Doomsday Dora!
0:19:47 > 0:19:50Less of the Doomsday!
0:19:51 > 0:19:53Crisp?
0:20:00 > 0:20:03- Welcome home.- Not so fast!
0:20:03 > 0:20:05We're back, but not stabilised.
0:20:05 > 0:20:10Any quick drop in speed and the worlds will be pulled apart again.
0:20:10 > 0:20:13Sadiq, that girl... that must be Muna.
0:20:13 > 0:20:15She's just as Reese described.
0:20:19 > 0:20:21Dad, what is that room?
0:20:21 > 0:20:24The cryogenic cell.
0:20:24 > 0:20:25It cools the machine.
0:20:25 > 0:20:28No-one should be in there!
0:20:28 > 0:20:34Those girls are linked into the electrical circuit of the machine.
0:20:34 > 0:20:38- It's impossible.- No, it's not!
0:20:38 > 0:20:41They're using their minds.
0:20:41 > 0:20:45Two minutes to permanent realignment!
0:20:45 > 0:20:48Whatever they're doing, they've got to keep doing it,
0:20:48 > 0:20:49or the worlds will remain apart.
0:20:49 > 0:20:53Look at them, they don't have two minutes!
0:20:54 > 0:20:56Muna!
0:20:56 > 0:20:59Hold on.
0:21:00 > 0:21:02Hold on, children.
0:21:03 > 0:21:06Don't go! I need you!
0:21:08 > 0:21:09No!
0:21:18 > 0:21:20Dad, where's Muna?
0:21:20 > 0:21:23- I don't know.- She's gone.
0:21:23 > 0:21:25It's destroyed her.
0:21:25 > 0:21:27- We can't do this, Dad!- We have to.
0:21:27 > 0:21:32Just 90 seconds more and we'll be one world. Just how it was before.
0:21:32 > 0:21:35Reese can't take all that electricity, can she?
0:21:35 > 0:21:3880 seconds to realignment.
0:21:38 > 0:21:40'Evacuate...'
0:21:40 > 0:21:43Reese, please stop!
0:21:43 > 0:21:46(Save yourself, Holly. Save yourself.)
0:21:48 > 0:21:50Stop everything.
0:21:50 > 0:21:53Save Reese. She is going to fry!
0:21:53 > 0:21:55Reese is wired into the machine!
0:21:55 > 0:21:57Yeah, and it's killing her.
0:21:57 > 0:21:5960 seconds to realignment.
0:22:03 > 0:22:05I'm not going to leave you.
0:22:05 > 0:22:10(I'm part of the chain, Holly. I just am.)
0:22:10 > 0:22:12I'm sorry I didn't believe you.
0:22:18 > 0:22:21Reese can't take much more!
0:22:21 > 0:22:24She's dissolving. We've got to cut the power now.
0:22:24 > 0:22:26- 40 seconds.- What are you waiting for?
0:22:26 > 0:22:30- Do you want her to vaporise like little Muna?- Switch it off, Kat!
0:22:33 > 0:22:34No, no, no, no, Kat!
0:22:34 > 0:22:37The realignment isn't stable!
0:22:37 > 0:22:41I can't let Reese die! She's not just some cog in your machine.
0:22:41 > 0:22:46She's a human being. She's not just some particle or sparticle.
0:22:46 > 0:22:4830 seconds to realignment.
0:22:48 > 0:22:51Right.
0:22:54 > 0:22:58Barker. What are you doing? Barker?
0:22:58 > 0:23:00Then you're going to need this.
0:23:00 > 0:23:04Barker, 20 seconds to realignment. No! Don't do it, Barker! No!
0:23:06 > 0:23:09We can't let that child die!
0:23:09 > 0:23:12- Help me, keep him back!- We've got to stop the machine! Get off me.
0:23:17 > 0:23:19Five... four... three... two...
0:23:24 > 0:23:28The machine's crashing! It's shattered.
0:23:28 > 0:23:31The whole cause shattered.
0:23:31 > 0:23:33She's destroyed your life's work, Barker.
0:23:33 > 0:23:36Sorry about Muna.
0:23:44 > 0:23:46What's happening?
0:23:49 > 0:23:52The realignment was only temporary.
0:23:54 > 0:23:55I'm being pulled back.
0:23:58 > 0:24:03No! But my mum! Give her this.
0:24:03 > 0:24:06It's a diary of what I've been doing.
0:24:06 > 0:24:11Find our Grandad and tell him Jeffrey's awesome!
0:24:13 > 0:24:17- And give him this back Dora! - Tell Mummy I miss her!
0:24:17 > 0:24:19I will.
0:24:19 > 0:24:21I promise.
0:24:24 > 0:24:27Children, the Quantum Portal is closing,
0:24:27 > 0:24:32you must find a new gateway to the adult dimension.
0:24:32 > 0:24:34We are safe but locked away.
0:24:38 > 0:24:41You must free us.
0:24:41 > 0:24:47And this key will open secrets beyond science.
0:24:47 > 0:24:49Journey to the Quantum Nexus.
0:24:49 > 0:24:52- What's that?!- It's... - How do we use the key?
0:24:55 > 0:24:58No!
0:24:58 > 0:25:00I'm sorry, Dad.
0:25:00 > 0:25:03No, I'm the one that's sorry.
0:25:13 > 0:25:16The machine's broken. I've failed.
0:25:27 > 0:25:28No.
0:25:30 > 0:25:35You saved the world. The piece of paper your dad left you.
0:25:35 > 0:25:38It's the master code to shut down all the nuclear power stations!
0:25:38 > 0:25:42We can make our world safe to live in.
0:25:42 > 0:25:46I don't think I can do this any more.
0:25:46 > 0:25:47Of course you can.
0:25:47 > 0:25:50We'll be together. All of us.
0:25:50 > 0:25:54All of us Sparticles. We're a family.
0:26:01 > 0:26:04You're my best friend, you know that?
0:26:04 > 0:26:06And you're mine, too.
0:26:12 > 0:26:15That's a Sacred Wheel and Cross. It's Celtic.
0:26:15 > 0:26:18The Quantum Nexus was seen as a place of magic in ancient times.
0:26:18 > 0:26:20Maybe in the future it'll be claimed by scientists.
0:26:20 > 0:26:24Megan? Is the Quantum Nexus a mega confluence of ley lines?
0:26:24 > 0:26:27That's exactly what it is.
0:26:27 > 0:26:30We need to rescue Muna as well as the parents.
0:26:30 > 0:26:32She's still stuck in limbo.
0:26:32 > 0:26:34Shut up, Reese.
0:26:39 > 0:26:41Reese, you're incredible.
0:26:41 > 0:26:43Hey, Sparticles, let's hear it for Reese.
0:26:47 > 0:26:51Well, you might have to defer your horticulture course.
0:26:51 > 0:26:53Life on the road is an education in itself.
0:26:53 > 0:26:55But I need a study partner.
0:26:57 > 0:26:59Gross!
0:27:00 > 0:27:03Listen up, everybody! Here's the deal.
0:27:03 > 0:27:06I thought we could take a brief rest,
0:27:06 > 0:27:10maybe stock up on a few tools for the Spartivan and...
0:27:10 > 0:27:15hit the road to the Quantum Nexus and free the adults!
