His parents, as a result of their scientific discoveries, are kidnapped by a pharmaceutical company known mysteriously as the Corporacy. Charlie, closely avoiding being kidnapped himself, sets out to find them and ends up on board Circe, a circus ship making its way to Paris. On board he befriends most of the circus performers as well as (using the ability) a pride of beautiful performing lions who seek the boy's help to escape their cruel trainer, Maccomo. Meanwhile, the vicious criminal Rafi Sadler, who is employed by the Corporacy, is hot on his heels, going to any lengths to get his hands on Charlie. The circus ship arrives in Paris and Charlie escapes with the lions. They make their way to Gare d'Austerlitz where they hide on the Orient Express which is destined for Venice, the place Charlie's parents are rumoured to have been taken.
