Voir Leonardo, Series 1 - Episode 6

Lorenzo smuggles Leo into the palace to show him an extraordinary object - a plain box, which produces an amazing light show. Leo creates a replica and they swap the boxes so Leo can discover how the original works. But as Leo and Lorenzo set out to return the original, they're attacked and the box is stolen. What with Mac's suspicious behaviour and Piero's lethal security system, Leo's fascination with the box threatens not only to land his friend Lorenzo in trouble, but also to lead Leo himself into the gravest danger.
