0:00:08 > 0:00:10It's fragile and worth millions.
0:00:10 > 0:00:13By all means, run faster(!)
0:00:15 > 0:00:17Ah! Magnifico.
0:00:17 > 0:00:23Remember, Lorenzo. People judge you by the things you possess.
0:00:23 > 0:00:28Fine works make a marvel of the name Medici, our name.
0:00:28 > 0:00:31But we've more than priceless treasures.
0:00:31 > 0:00:33Behold!
0:00:33 > 0:00:36The centrepiece.
0:00:36 > 0:00:38Hm. A box.
0:00:38 > 0:00:41SCOFFS Attenzione.
0:00:52 > 0:00:55The lightning box!
0:00:55 > 0:01:00- Magic!- You sound like a peasant. You'll believe in dragons next!
0:01:00 > 0:01:03Created by an Arabian scientist
0:01:03 > 0:01:07half a century ago, it still baffles the finest minds in the world.
0:01:08 > 0:01:13We may yet unlock its secret.
0:01:50 > 0:01:53- So?- It's a box.
0:01:53 > 0:01:57That's right. I sneaked you in past my father just to see a box(!)
0:01:57 > 0:02:02Turn the handle. You'll see. Incredible.
0:02:06 > 0:02:09LEONARDO LAUGHS
0:02:23 > 0:02:29How did he make it? How did he create light and energy?
0:02:29 > 0:02:31What law of physics has he unlocked?
0:02:31 > 0:02:36- You don't know how it works? - Fantastico!- You must have some idea.
0:02:36 > 0:02:38- May I?- No. Maybe not.
0:02:38 > 0:02:41- FOOTSTEPS - Maybe we should...
0:02:41 > 0:02:46- Is there a candle inside? - No time to find out. Leo, come on!
0:02:49 > 0:02:51The pearl.
0:02:51 > 0:02:55Each one a perfect luminescent orb.
0:02:55 > 0:03:00I want to see the lustrous play of light across the surface.
0:03:00 > 0:03:03We call this iridescence...
0:03:03 > 0:03:07Um, I think you need to take another look at our subject?
0:03:07 > 0:03:11..appears to change colour as you view it...
0:03:11 > 0:03:18- What is it? - I'm trying to work out if mirrors can refract light into fragments.
0:03:18 > 0:03:23- Oh, yeah. The lightning box. - You should have been there, Tom.
0:03:30 > 0:03:34- You've caught the light perfectly. - You think so?
0:03:34 > 0:03:36Although shouldn't pearls be round?
0:03:36 > 0:03:38They are round...!
0:03:38 > 0:03:44..For an artist each object exists in relation to light.
0:03:44 > 0:03:47Your job is to find that light.
0:03:47 > 0:03:51Tomaso, you will assist me.
0:03:55 > 0:03:57Thank you, maestro. I'm...
0:03:57 > 0:04:00I'm ready. I can do this.
0:04:00 > 0:04:05You will complete the detailing on Signora Di Noto's birthday portrait.
0:04:05 > 0:04:12- I want pearls worthy of gracing a wealthy neck.- I won't let you down. - What is all this mess?
0:04:16 > 0:04:18- Cracked it?- No.
0:04:18 > 0:04:22- Is there any chance of another look? - No. We had an intruder.
0:04:22 > 0:04:26Someone trying to steal the box. Had an arrow in his leg.
0:04:26 > 0:04:30Dad's upped the security.
0:04:34 > 0:04:40That's the rent paid for another month, no thanks to you idle...
0:04:43 > 0:04:50- I wiped the floor with the last person who broke in here.- You never cleaned a floor in your life!
0:04:50 > 0:04:56Carlo Cazali! It's been years! What are you doing here?
0:04:56 > 0:05:00Same as ever. Look at you! You've got your own place!
0:05:00 > 0:05:06- Hanging in there. - Remember those nights in the gutter? I've missed you, Mach.
0:05:06 > 0:05:10- He was like a wee brother to me. - Yeah. Nearest thing I had to family.
0:05:10 > 0:05:12How sad is that?
0:05:14 > 0:05:18Pat, get us some fruit. Presto! Signor! Yes, sir!
0:05:20 > 0:05:23GROANS
0:05:23 > 0:05:25Long story.
0:05:27 > 0:05:31- So, what brings you here from Pisa? - Other than my old mate?
0:05:33 > 0:05:35- Working for Pozzo.- Pozzo?
0:05:35 > 0:05:39Pisa's most wanted. He's got his eye on something.
0:05:39 > 0:05:44- What Pozzo asks for...!- He wants a wee thing called the lightning box.
0:05:44 > 0:05:50- At the Palace of Piero de' Medici. Security will be tight. - Tell me about it.
0:05:53 > 0:05:58It's a tough one, Mach. I need your help. You know his son, Lorenzo?
0:05:59 > 0:06:02Well, he's kind of...a friend.
0:06:03 > 0:06:07A friend? You mean like a friend to your wallet?
0:06:09 > 0:06:11He's a Medici, Mach.
0:06:11 > 0:06:14He can buy himself 20 lightning boxes.
0:06:14 > 0:06:18For people like you and me, it's a matter of life or...
0:06:29 > 0:06:32CLANKING
0:06:46 > 0:06:48Bene.
0:07:01 > 0:07:03Molto bene.
0:07:03 > 0:07:06And if I key in the wrong code?
0:07:27 > 0:07:28CHUCKLES
0:07:30 > 0:07:32Now, get a cloth.
0:07:32 > 0:07:35BELL TOLLS
0:07:35 > 0:07:39- Daddy's got a new toy? - You heard? Of course! You're Mach!
0:07:39 > 0:07:43Hope he's got good security. Everybody in Florence wants that.
0:07:43 > 0:07:45- Master Lorenzo!- Signor Verrocchio.
0:07:45 > 0:07:50Don't you have anything better to do than infest my property?
0:07:50 > 0:07:52Hm?
0:07:58 > 0:08:04- The lightning box. He's gone a bit Leo about it!- Right up his street.
0:08:04 > 0:08:08- My dad will be so impressed. - It can't be candles and mirrors.
0:08:08 > 0:08:11It seemed to have its own energy, power.
0:08:11 > 0:08:13Own energy. Power.
0:08:14 > 0:08:16Let's see.
0:08:19 > 0:08:22I can't work it out if I can't see inside.
0:08:22 > 0:08:29- Borrow it.- Lorenzo won't go for it. - If it looks like a box, it's a box, even if it doesn't work.
0:08:30 > 0:08:34This has got Leo going nuts. Any way we can help him?
0:08:34 > 0:08:37- No. Can't risk it. - What if no-one knew it was missing?
0:08:37 > 0:08:41I could build a replica. No-one would know.
0:08:41 > 0:08:43I could solve the mystery.
0:08:43 > 0:08:49- Succeed where generations have failed.- You'd look good in front of Papa. It's a win-win situation.
0:08:51 > 0:08:57All right. The exhibition doesn't open for a few days. Promise to put it back.
0:08:57 > 0:09:03Lorenzo, I give you my most solemn promise that I will get it back to you safe and sound.
0:09:03 > 0:09:06- Mach's witness to that, aren't you? - Huh?
0:09:06 > 0:09:09Yeah. Sure.
0:09:27 > 0:09:29SPEAK IN ITALIAN
0:09:29 > 0:09:32What IS that?
0:09:32 > 0:09:37- You didn't say anything about a security code!- I didn't know!
0:09:37 > 0:09:41- That's that, then. Come on. - No, wait. We can work it out.
0:09:41 > 0:09:44- Let me think.- There's no time.
0:09:44 > 0:09:49- A date?- Date of birth. People are incredibly predictable.
0:09:49 > 0:09:54- Papa's not predictable.- Trust me. They almost always go for that one.
0:09:54 > 0:09:56- So I'm told.- Lorenzo.
0:09:56 > 0:10:03- What's your dad's birthday? - 9th June. Same as mine. Different year. Mine's '53, his is 1425.
0:10:03 > 0:10:07- Nine six 1425. What do you think? - Worth a shot.- No!
0:10:07 > 0:10:13It's definitely not worth a shot. If we get it wrong a hideous alarm...
0:10:13 > 0:10:17Lorenzo, relax. There's nothing to worry about, OK?
0:10:25 > 0:10:27Nine.
0:10:27 > 0:10:29Six.
0:10:30 > 0:10:32One.
0:10:32 > 0:10:34Four.
0:10:34 > 0:10:36Two.
0:10:43 > 0:10:45Five.
0:10:51 > 0:10:53See? What did I tell you?
0:11:10 > 0:11:12Hurry up!
0:11:17 > 0:11:20Come on! They're coming!
0:11:25 > 0:11:28CLATTERING
0:11:31 > 0:11:34- Maybe no-one heard it. - What was that? >
0:11:34 > 0:11:36Come on! Quick!
0:11:44 > 0:11:46There's been a breach.
0:11:46 > 0:11:48Come on!
0:11:50 > 0:11:53Master Lorenzo. There's been a break-in.
0:11:53 > 0:11:55N-no? Really?
0:11:55 > 0:11:58You must have heard that sound.
0:11:58 > 0:12:01Oh, yes. From the kitchens?
0:12:01 > 0:12:07- From the exhibition room. - You know how sound travels in big old palaces!
0:12:07 > 0:12:11Ha. So you haven't seen anything?
0:12:29 > 0:12:31Well?
0:12:31 > 0:12:35Not easy. He's set up a security code.
0:12:35 > 0:12:39There's some sort of contraption with a lethal-looking blade.
0:12:42 > 0:12:45- But you did get it? - What do you think?
0:12:45 > 0:12:49- Don't be coy, man. Hand it over. - My mate Leo's got it.
0:12:49 > 0:12:56- What?- Relax. He's a genius. He'll build one for Lorenzo. You keep the original. Everyone's a winner.
0:12:56 > 0:13:00- I've got Pozzo breathing down my neck.- Don't worry.
0:13:00 > 0:13:04Remember how I showed you the ropes when you landed on the street?
0:13:04 > 0:13:09Big brother Carlo. You'd not put new friends before that, would you?
0:13:21 > 0:13:23Father!
0:13:24 > 0:13:26Father! Er...
0:13:26 > 0:13:28Um... Oh!
0:13:28 > 0:13:31Oh, yes. How are you?
0:13:32 > 0:13:36- We had another breach in security last night.- Anything stolen?
0:13:36 > 0:13:41No. And I'll make sure it stays that way. The Duke is coming tomorrow.
0:13:41 > 0:13:45- Tomorrow? - He insists on a private view.
0:13:46 > 0:13:48Stay out of that room, Lorenzo.
0:13:48 > 0:13:52It's dangerous. We wouldn't want any nasty accidents.
0:13:52 > 0:13:54Would we?
0:14:04 > 0:14:07Leo, we have to put it back now.
0:14:07 > 0:14:10- So where is it?- It's right here.
0:14:10 > 0:14:14- That's a broken mess.- I had to take it apart to see how it works.
0:14:14 > 0:14:19- What if you can't put it back together?- You can, can't you, Leo?
0:14:20 > 0:14:24I drew and numbered every piece. I can rebuild it exactly as it was.
0:14:24 > 0:14:28- Do it now. It has to be back tonight.- What?- The Duke's coming.
0:14:28 > 0:14:33- The replica won't work. My dad will go mental...- Lorenzo, why...?
0:14:33 > 0:14:40..shamed in front of the Duke. I'll be branded a thief. He'll never forgive me I'll be grounded forever!
0:15:01 > 0:15:06- What's the problem?- Can't do it. The box is going back to the palace.
0:15:06 > 0:15:09I told you, Lorenzo's a friend.
0:15:10 > 0:15:12And I'm not?
0:15:14 > 0:15:18If I don't get that box to Pozzo, he'll kill me.
0:15:18 > 0:15:22You know he will. He'll slit my throat.
0:15:22 > 0:15:25So what's it going to be, Mach?
0:15:30 > 0:15:33- Have you finished?- Not quite.
0:15:38 > 0:15:40- Have you finished now?- No.
0:15:45 > 0:15:47- How about now?- It fits!
0:15:49 > 0:15:52No, Lorenzo. I haven't finished yet.
0:16:00 > 0:16:05- Not quite sure what I did. I just need to...- No way!
0:16:05 > 0:16:08I'm not taking any more chances.
0:16:08 > 0:16:11I have to get back.
0:16:14 > 0:16:17Ah! Think I'm gonna be sick!
0:16:40 > 0:16:43Are you OK? I can make another one.
0:16:43 > 0:16:47I've studied every piece. I can do it. I know I can.
0:16:58 > 0:17:01- LAUGHTER - Result! The old team!
0:17:02 > 0:17:04Why did you do that?
0:17:04 > 0:17:09- Just a wee push. Toughen him up a bit.- It wasn't necessary.
0:17:10 > 0:17:12This calls for a feast!
0:17:12 > 0:17:15- Here. On me. - Yes! Yes! Come on!
0:17:17 > 0:17:22- Don't you have to get that back to Pozzo?- I'm not working for Pozzo.
0:17:22 > 0:17:25This little baby's all mine.
0:17:25 > 0:17:30- But...- I knew if I told you I was in danger you'd help me.
0:17:30 > 0:17:34You're easy to read, Mach, even if you think you're not.
0:17:34 > 0:17:36You're easy to manipulate. Soft.
0:17:38 > 0:17:40Don't worry.
0:17:40 > 0:17:42I won't tell anyone.
0:18:00 > 0:18:05- Is Lorenzo OK?- Why do you ask? - I heard the box got stolen.- Did you?
0:18:05 > 0:18:10- Yeah.- Any word on who stole it? - Er... Carelli.
0:18:11 > 0:18:14Antonio Carelli, notorious thief?
0:18:15 > 0:18:18- Is that the best you can do?- Er...
0:18:18 > 0:18:22You're making another box. It will be all right for Lorenzo?
0:18:22 > 0:18:24No harm done?
0:18:48 > 0:18:52- Try again! - I must have missed something.
0:18:52 > 0:18:56- It won't work.- How long do you need? - A day? A month? Who knows?
0:18:58 > 0:19:02So...this Carelli. Where does he live?
0:19:02 > 0:19:08- I don't know. Why?- I'm going to have to get the real box back from the thief, which is Carelli?
0:19:08 > 0:19:13- Yeah.- So shall we go and find him? - Don't! It could be dangerous.
0:19:13 > 0:19:17- Anyway, what about the curfew? - I made a promise to a friend.
0:19:20 > 0:19:23All right. I know where Carelli lives.
0:19:23 > 0:19:26Leave it to me. I'll see what I can do.
0:19:33 > 0:19:40- You missed all the fun. - You're not going?- I got the feeling I'd outstayed my welcome.
0:19:42 > 0:19:47I'm sorry. You were right. I was wrong.
0:19:47 > 0:19:52Aye. If you want to succeed in life, listen to your big brother Carlo.
0:19:52 > 0:19:56There's no-one I respect more. You taught me everything.
0:19:56 > 0:20:00What do I owe Lorenzo? He doesn't have one tenth of your talent.
0:20:00 > 0:20:04- Your brains. - Just another over-privileged brat.
0:20:05 > 0:20:08Stay. Have a drink with me.
0:20:08 > 0:20:10Sure.
0:20:11 > 0:20:13Sure. Why not?
0:20:19 > 0:20:22Got to be quicker than that, wee man.
0:20:41 > 0:20:44To you, the smartest guy I know.
0:20:45 > 0:20:50And to you, the second smartest. And to friendship.
0:20:50 > 0:20:52To friendship.
0:21:14 > 0:21:17It doesn't work.
0:21:17 > 0:21:20- Couldn't do it. - You should get some sleep.
0:21:20 > 0:21:22- I'm waiting.- What for?
0:21:24 > 0:21:26KNOCK ON DOOR
0:21:27 > 0:21:29A friend.
0:21:38 > 0:21:41- So, you found this Carelli.- Mm.
0:21:41 > 0:21:44Is that who stole it? Yeah.
0:21:46 > 0:21:49He didn't cause you any...trouble?
0:21:49 > 0:21:51No.
0:21:51 > 0:21:55Look, I've got to get going. I'll see you around?
0:21:58 > 0:22:01He got the lightning box back?
0:22:01 > 0:22:04- Yeah.- That was brave of him.
0:22:05 > 0:22:07Not really.
0:22:13 > 0:22:15Be careful!
0:22:32 > 0:22:36Valerian, a sleeping potion.
0:22:36 > 0:22:38Knocked you clean out.
0:22:40 > 0:22:45- My box?- My mate Leo's putting it back on display right now.
0:22:46 > 0:22:49CARLO CHUCKLES
0:22:49 > 0:22:50Well played!
0:22:52 > 0:22:56You always did know how to play on a person's weakness.
0:22:56 > 0:23:00- And you always did respond to flattery.- Undone by vanity!
0:23:02 > 0:23:06Oh, well. Easy come, easy go.
0:23:08 > 0:23:11Mind you...
0:23:11 > 0:23:17I will be surprised if your mate can get that box back in one piece.
0:23:17 > 0:23:21That blade, I've seen that before. Get the code wrong...
0:23:22 > 0:23:25- Whoosh!- We cracked the code.
0:23:25 > 0:23:28They won't change that after the break-in?
0:23:28 > 0:23:30Let's hope they haven't.
0:23:30 > 0:23:35Otherwise your mate will be sliced down the middle like a fine salami.
0:24:09 > 0:24:14Here we go. What's your dad's birthday? 9th June um...1425.
0:24:25 > 0:24:32Nine, six, one, four...
0:24:35 > 0:24:37Stop!
0:24:39 > 0:24:41Look up.
0:24:42 > 0:24:44Some kind of guillotine?
0:24:44 > 0:24:47- What's the problem? We know the code.- They changed it.
0:24:47 > 0:24:50Yeah, that's not good.
0:24:50 > 0:24:52- Are you sure?- Yes.
0:24:52 > 0:24:55No. Lorenzo, did your dad tell you anything?
0:24:55 > 0:24:57No, but, um...
0:24:58 > 0:25:01I watched him. I watched him key in the code.
0:25:01 > 0:25:04- And?- And...
0:25:04 > 0:25:07- I don't know. I can't remember.- Try.
0:25:07 > 0:25:08I'm trying!
0:25:08 > 0:25:11Take a deep breath.
0:25:11 > 0:25:15- Calm down. Think!- OK, so...
0:25:17 > 0:25:19The Duke is coming tomorrow.
0:25:19 > 0:25:23- Tomorrow? - He insists on a private view.
0:25:26 > 0:25:27Focus!
0:25:29 > 0:25:33- The first four are the same. 9614. - What were the last two?
0:25:36 > 0:25:38They were the same.
0:25:38 > 0:25:40I'm not sure. I'm not sure.
0:25:43 > 0:25:49- What's your dad's birthday? - 9th June. Same as mine. Different year. Mine's '53. His is 1425.
0:25:49 > 0:25:52Was it 53, Lorenzo?
0:25:53 > 0:25:55Yes.
0:25:55 > 0:25:59- Yes, it was 53.- He changed it to YOUR birthday?- Are you sure?
0:25:59 > 0:26:02Yes, I'm sure.
0:26:02 > 0:26:05If I key in the wrong code...
