Teenager Denny Kovacz is beaten up by a street gang, until a masked man in 'Superhero' costume comes to his rescue, gets knife-stabbed by chases the scum and flees, technically a wanted assailant himself. The unsavory scene is posted on Internet. *Hospitalized teen thug Boris 'Bärchen' ('bear cub') nor Denny are prepared to identify anyone else, obeying to the derelict neighborhood's code of silence, which in Denny's case is soon recalled in cruel and demeaning ways . Mates, Tariq, Hans and their partners get little cooperation of the field, even worse, except from disheartened street worker Harald Ihlenburg, and valuable research from Wolle,, also pointing them to local journalist Sebastian Reckziegel, who runs the super-hero's 'fan site' but maintains it's impartial and necessary in the authorities-neglected context. He's the next to get beaten up, at home, but macho gang-leader Sven Ehring isn't done.
