In his old neighborhood in West Berlin, 13-year-old Kalle (Gerhard Kuhn) had commanded respect as the “sheriff” of the Teddy Gang. After his family moves to East Berlin, he has trouble fitting in with his new classmates, especially his deskmate and rival Andreas. But when Kalle’s older brother Robbi encourages him to become involved in crime, he must rely on Andreas and his classmates to help get him out of trouble.
