A stranger is hunting skinheads. He shoots her without leaving any usable traces. Ballauf and Schenk seek help from the Office for the Protection of the Constitution. But the officer doesn't speak, but the spy, who the Office for the Protection of the Constitution smuggled into the scene, does: All of the victims were involved in an attack on a Turkish restaurant years ago . Will the victims take revenge sooner, or should the police be deliberately sent down the wrong track? When it becomes clear that everyone is playing their own game, Ballauf and Schenk have to hang on to the officer. This is dangerous and against all police regulations - but successful in the end.
