0:00:22 > 0:00:25Second, first, ground...
0:00:27 > 0:00:29That's it, cellar.
0:00:32 > 0:00:34KNOCK AT DOOR
0:00:34 > 0:00:35Cat?
0:00:39 > 0:00:40- Hey!- Hey.
0:00:41 > 0:00:44What if I told you I may have found your cave?
0:00:44 > 0:00:45Take a look at this.
0:00:50 > 0:00:53There's another area here, underneath the cellar.
0:00:53 > 0:00:55See?
0:00:55 > 0:00:57How do we get down there?
0:00:58 > 0:00:59This is the door.
0:01:02 > 0:01:04But it's locked, so...
0:01:04 > 0:01:05Maybe the ghosts have gone away.
0:01:05 > 0:01:07I mean, we haven't heard them knocking lately.
0:01:07 > 0:01:10They'll be back. I can feel it. We need to find that oubliette...
0:01:10 > 0:01:12If Alice and Henry's bones are really down there...
0:01:12 > 0:01:13Alice and Henry?
0:01:13 > 0:01:16Those were the names we saw on that monument, weren't they?
0:01:16 > 0:01:17What monument?
0:01:17 > 0:01:19Far side of the castle grounds, by the old mill tower.
0:01:19 > 0:01:20Do you know who they are?
0:01:20 > 0:01:23Yeah, they're two kids who disappeared in the '60s.
0:01:23 > 0:01:24Disappeared?
0:01:24 > 0:01:26Yeah, we think they're haunting the place.
0:01:26 > 0:01:28It's just a theory.
0:01:28 > 0:01:30But what were you two doing over by the mill tower?
0:01:30 > 0:01:33- We were looking for...- Something. - "Something"? Right.
0:01:33 > 0:01:35What's going on in here?
0:01:35 > 0:01:37Everyone outside, for Life Skills.
0:01:37 > 0:01:38Now!
0:01:40 > 0:01:43Since when did you stop telling me stuff, Noah?
0:01:54 > 0:01:55Nettles. Very good, Lexy.
0:01:55 > 0:01:56Ow!
0:01:56 > 0:01:58Wild garlic - excellent.
0:01:59 > 0:02:01Dandelions. Good, Luke...
0:02:01 > 0:02:03Gaia says you can eat this.
0:02:03 > 0:02:05- Clover? Correct.- Yes!
0:02:05 > 0:02:07Is that everyone?
0:02:07 > 0:02:09Hurry up, Slim! It's supposed to be a race.
0:02:11 > 0:02:13Mint?
0:02:13 > 0:02:15You got that from the castle herb garden, didn't you?
0:02:15 > 0:02:16Yep.
0:02:16 > 0:02:19The task was to find something edible growing wild.
0:02:19 > 0:02:20Oh...
0:02:20 > 0:02:23One lap of the castle grounds for coming last -
0:02:23 > 0:02:25- and one for cheating. - LAUGHTER
0:02:25 > 0:02:28- Well, I didn't cheat, I just misunderstood the...- Go!
0:02:54 > 0:02:56We're hardly going to find wood for a fire in here.
0:02:56 > 0:02:59Who says we're looking for wood? Keep watch.
0:03:02 > 0:03:04There are more of these dotted around.
0:03:04 > 0:03:05We need to find them all.
0:03:05 > 0:03:07What are we doing, exactly?
0:03:42 > 0:03:44It's like one of those cookery programmes,
0:03:44 > 0:03:46where they give you five ingredients
0:03:46 > 0:03:48and you have to conjure up something delicious out of it!
0:03:48 > 0:03:50- LAUGHTER - Hey, AJ?
0:03:50 > 0:03:53I've got something for you.
0:03:53 > 0:03:55Ugh! Gregor...
0:03:55 > 0:03:57your cologne's a bit strong.
0:03:57 > 0:03:59It's not me. It's this.
0:03:59 > 0:04:01It's for you.
0:04:01 > 0:04:03Oh. Thanks, Gregor. You shouldn't have(!)
0:04:03 > 0:04:05It's from Mackenzie.
0:04:05 > 0:04:08Guys, guys...listen up, I've found something...
0:04:09 > 0:04:11Oh. Hi, Gregor.
0:04:12 > 0:04:13Ooh!
0:04:13 > 0:04:15A letter for AJ...
0:04:15 > 0:04:19- LAUGHTER - ..and smelling of air freshener.
0:04:19 > 0:04:21Nice.
0:04:21 > 0:04:22- AS MACKENZIE:- "Hey, gorgeous...
0:04:22 > 0:04:26"I just wanted to say, I'm loving the phone you gave me..."
0:04:26 > 0:04:28You gave her your new phone?
0:04:28 > 0:04:30Yeah. So?
0:04:30 > 0:04:32"Meet me at the cafe this afternoon
0:04:32 > 0:04:34"and I can thank you in person.
0:04:34 > 0:04:36"Laters, Mackenzie."
0:04:37 > 0:04:39LAUGHTER
0:04:39 > 0:04:41Looks like you've got an admirer, AJ.
0:04:41 > 0:04:44You gave her your phone? That's so sweet. You must really like her.
0:04:44 > 0:04:45No!
0:04:45 > 0:04:48- AJ's in love!- Aw!
0:04:48 > 0:04:51Yeah, right. I mean, as if. Yuck!
0:04:51 > 0:04:53What's he doing in here?
0:04:53 > 0:04:55Oh. Hi, Lexy.
0:04:55 > 0:04:57Nothing. I mean, when I say "nothing",
0:04:57 > 0:04:59I'm obviously here doing something.
0:04:59 > 0:05:03- Obviously. I...- Forget it. Life's too short. Anyone seen Noah and Cat?
0:05:03 > 0:05:05They were supposed to meet me outside to help me with the fire,
0:05:05 > 0:05:07but I can't find them anywhere.
0:05:12 > 0:05:14OK, that's the last.
0:05:14 > 0:05:16The heat is on.
0:05:16 > 0:05:17Well done.
0:05:17 > 0:05:20Dandelion, nettle and clover soup....delicious.
0:05:20 > 0:05:24Message from your dad, Gaia. He needs to see you after lunch.
0:05:24 > 0:05:27- You can go up to the office. - OK, sure.
0:05:27 > 0:05:30No, thanks, I'm allergic to dandelions.
0:05:30 > 0:05:34Mmm. It's really not that bad.
0:05:34 > 0:05:37It's hot water, with dandelion heads floating in it.
0:05:37 > 0:05:39Trust me, it's bad.
0:05:39 > 0:05:42How are you getting on with that new phone, AJ?
0:05:42 > 0:05:44Um...good. Yeah.
0:05:44 > 0:05:46Not managed to lose it yet, then?
0:05:46 > 0:05:47Nope.
0:05:49 > 0:05:50Oh!
0:05:50 > 0:05:53Is it me, or is it hot in here?
0:05:53 > 0:05:54It's hot.
0:05:54 > 0:05:55Yeah, tropical.
0:05:56 > 0:05:59No wonder - the radiator's blasting out.
0:05:59 > 0:06:01What? They shouldn't even be on.
0:06:03 > 0:06:04Guys?
0:06:06 > 0:06:08Oubliettes - and guess what?
0:06:08 > 0:06:10I think I know where ours is...
0:06:13 > 0:06:15Where are we going?
0:06:15 > 0:06:16Hello? Major Javadi, here.
0:06:16 > 0:06:20Yeah, I need a technician to come out and check out the boiler.
0:06:23 > 0:06:25What exactly is an oubli-wotsit, anyway?
0:06:25 > 0:06:27If you'd come with us yesterday,
0:06:27 > 0:06:29instead of hanging out with the girlies, you'd know.
0:06:29 > 0:06:30It's a secret dungeon.
0:06:30 > 0:06:33We think Alice and Henry's bones might be down there.
0:06:33 > 0:06:34- Cool.- Here we go.
0:06:39 > 0:06:42You have to admit, it does look like an oubliette.
0:06:42 > 0:06:45"In memory of our beloved children, Alice and Henry Carter -
0:06:45 > 0:06:48"gone, but always in our hearts."
0:06:48 > 0:06:50That's so sad.
0:06:50 > 0:06:52Do you think they built a stone memorial
0:06:52 > 0:06:54where the bodies disappeared?
0:06:54 > 0:06:56Yeah - the oubliette.
0:06:56 > 0:06:58Why weren't the bodies ever found?
0:06:58 > 0:07:02Maybe there was a zombie waiting down there and ate them all up...
0:07:02 > 0:07:05AJ GROWLS GAIA SQUEALS
0:07:05 > 0:07:08I'm not sure this is an oubliette, Slim.
0:07:08 > 0:07:11There are steps here, look. An oubliette wouldn't have those.
0:07:11 > 0:07:13So what is it, then?
0:07:13 > 0:07:15Some kind of secret passage.
0:07:16 > 0:07:17Shall we go down and take a look?
0:07:17 > 0:07:19- ALL:- No!- No way!
0:07:19 > 0:07:22I don't want to end up like Alice and Henry.
0:07:22 > 0:07:24Oh, don't be such wimps. Hey, I'm up for it.
0:07:26 > 0:07:27It's bolted down.
0:07:27 > 0:07:30Well, that's because it's a safety grid. Clue's in the name.
0:07:30 > 0:07:34OK, so let's find some tools and get it undone. Let's go.
0:07:35 > 0:07:38I really don't think we should be doing this.
0:07:38 > 0:07:39Come on...
0:07:41 > 0:07:44It was interesting, what Luke said - about those two kids?
0:07:46 > 0:07:49I'm thinking, what if they disappeared in this cave, too?
0:07:49 > 0:07:51Are you OK?
0:07:51 > 0:07:53Yeah.
0:07:53 > 0:07:54No.
0:07:54 > 0:07:57I don't like keeping secrets from my brother.
0:07:57 > 0:07:58I know.
0:07:58 > 0:08:01But until we know for certain that there really is
0:08:01 > 0:08:04this mysterious cave where people have disappeared...
0:08:05 > 0:08:07Listen to me.
0:08:07 > 0:08:09I sound like that girl in the village - what's her name -
0:08:09 > 0:08:10Mackenzie?
0:08:10 > 0:08:11Hardly.
0:08:13 > 0:08:15Please don't tell him, Noah.
0:08:15 > 0:08:17Not yet.
0:08:17 > 0:08:19WHISTLING
0:08:21 > 0:08:23KEYPAD BEEPS
0:08:46 > 0:08:47Is this a good idea?
0:08:47 > 0:08:50Because...you know...
0:08:50 > 0:08:53It seems a little bit dangerous to me.
0:08:53 > 0:08:56Hey, AJ!
0:08:56 > 0:08:58I can see your girlfriend from here -
0:08:58 > 0:09:01she's taking photos of the castle with her "love gift".
0:09:01 > 0:09:04I don't have a girlfriend - and I didn't give her a "love gift".
0:09:08 > 0:09:11- SLIM CACKLES - Got you!
0:09:11 > 0:09:13Slim, I thought you were into this?
0:09:13 > 0:09:14I am, I am.
0:09:14 > 0:09:17OK...something to take off the grid...
0:09:18 > 0:09:19Nope...
0:09:19 > 0:09:22I suppose we could always borrow my dad's tool-kit.
0:09:24 > 0:09:27Why didn't you suggest that ten minutes ago?
0:09:27 > 0:09:30Because his mind's on other things, now that he's got a girlfriend...
0:09:30 > 0:09:32Right! That's it.
0:09:32 > 0:09:33Where you going?
0:09:33 > 0:09:36She's not my girlfriend, all right? I'm off to make sure she knows that.
0:09:36 > 0:09:38This, I have got to see!
0:09:38 > 0:09:39No, Slim...
0:09:39 > 0:09:42Sorry. We'll do it when I get back, yeah? Promise.
0:09:44 > 0:09:46Well, looks like it's just you and me, then, Gaia.
0:09:46 > 0:09:50Two of us can't go by ourselves. It's not safe.
0:09:50 > 0:09:53And anyway, I forgot, my dad wants to talk to me.
0:09:53 > 0:09:55Sorry, Luke. Got to go.
0:10:05 > 0:10:06Perfect.
0:10:06 > 0:10:08How long will you be gone?
0:10:08 > 0:10:09A few days, maybe longer.
0:10:09 > 0:10:11Why can't I come with you?
0:10:11 > 0:10:12It's work. You'd be bored.
0:10:14 > 0:10:18I think Stockholm is where Slim's parents are stationed.
0:10:18 > 0:10:19Is it?
0:10:21 > 0:10:23Maybe I'll pop along, introduce myself.
0:10:23 > 0:10:25I don't see why I have to move out, though.
0:10:25 > 0:10:27I mean, Cat stays on her own...
0:10:27 > 0:10:30Indulge me. You know what a worrier I am.
0:10:31 > 0:10:33It's hot in here today, isn't it?
0:10:34 > 0:10:35Yeah, the boiler's sound.
0:10:35 > 0:10:38Some joker must have tampered with the thermostats.
0:10:38 > 0:10:40- KEYPAD BEEPS - I'll check them now.
0:10:40 > 0:10:43Great plan for getting us in, but how are we going to get out?
0:10:43 > 0:10:45Let's worry about that later.
0:10:48 > 0:10:50- RADIO:- 'If you're out and about today,
0:10:50 > 0:10:53'the weather looks set to hold, which will make a change.
0:10:53 > 0:10:55'You should see a welcome bit of sun, too...'
0:10:55 > 0:10:56AJ!
0:10:56 > 0:10:59- Hi...- This is awesome -
0:10:59 > 0:11:02- Mackajay's first date. - Who's "Mackajay"?
0:11:02 > 0:11:04You and her, you numpty! Sweet.
0:11:04 > 0:11:06- What's he doing here? - Yes, what are you doing here?
0:11:06 > 0:11:09Don't worry. I won't get in the way of your date.
0:11:09 > 0:11:10How many more times? This is not...
0:11:10 > 0:11:14Thanks, I'd appreciate that. Gregor, menus - now!
0:11:14 > 0:11:17How about you and I get to know each other a little better?
0:11:17 > 0:11:20So...what does "AJ" stand for, exactly?
0:11:20 > 0:11:23Adam Javadi. It's my name. It's also my dad's name. Now, I...
0:11:23 > 0:11:27I'm just "Mackenzie", because Mackenzie's like my surname,
0:11:27 > 0:11:30but my ma really liked it as a first name too, so, just "Mackenzie".
0:11:30 > 0:11:31Like Madonna?
0:11:31 > 0:11:34- More like Rihanna...- Or Adele?
0:11:34 > 0:11:37Why is everyone so interested in crashing our date?
0:11:37 > 0:11:39Yes, about this date...
0:11:39 > 0:11:42Are you two...together now?
0:11:42 > 0:11:44- No!- Yes.
0:11:44 > 0:11:45We're...
0:11:46 > 0:11:49..taking things...slowly?
0:12:01 > 0:12:03According to the map,
0:12:03 > 0:12:05the entrance to the underground area
0:12:05 > 0:12:08is definitely in this part of the cellar.
0:12:26 > 0:12:27What is in this thing?
0:12:38 > 0:12:40What is that?
0:12:43 > 0:12:45DEVICE BEEPS
0:12:49 > 0:12:50- BOTH:- Whoa.
