Director Rufus Lindner is shooting his first film: " Die Vatikankiller". With audience favorite Kai Rabe in the leading role, success is guaranteed. But suddenly chaos descends on the film team: A starlet is murdered, the bitchy leading man goes increasingly crazy, a drunken policeman causes a lot of trouble, and the sex-obsessed producer Egon Lütter doesn't make things any easier.

The twelve-year-old Emil and his father are haunted by bad luck. To take a break from a series of family disasters, Emil is allowed to spend a few days with a friend of the family, the female priest Hummel in Berlin. In the train he runs across the slick Max Grundeis who anaesthetizes Emil and steals his savings of 1500 DM. When he finally arrives in Berlin, Emil and a gang of street kids, led by the cheeky girl Pony Hütchen, try to find the gangster, who haunts the posh Hotel Adlon as a hotel thief. Meanwhile, to prevent anyone from finding out about Emil's mishap, Gypsi, a member of the gang of kids, passes himself off as Emil, thus wreaking havoc on the home of the priest.
