The body of little Malte Rahmani is found in the basement of the sports center. Affected, the chief inspectors Anna Janneke (Margarita Broich) and Paul Brix (Wolfram Koch) begin the investigation. The two quickly find out that the caretaker of the sports center, Sven Brunner (Stefan Konarske), often met Malte away from the center. In Brunner's subsequent interrogations, Janneke and Brix urgently search for the truth. The sports center is managed extremely strictly and performance-oriented by Joachim Voss (Golo Euler) - he is aiming for a high sports functionary position. Voss also places great value on the highest level for his twelve-year-old stepson Felix (Juri Winkler), both in sports and at school.
Felix' mother Meike (Lina Beckmann) can hardly defend herself against the verbal and physical humiliation of her husband Joachim - in which Felix also likes to take part. The two "men" have joined forces against them. Voss controls and manipulates Meike and Felix by fueling aggression and spreading fear, which ultimately leads to violence. In addition to Margarita Broich and Wolfram Koch, other leading roles include Juri Winkler, Golo Euler, Lina Beckmann, Stefan Konarske, Marek Harloff, Bruno Cathomas and Zazie de Paris. The team Sebastian Edschmid (camera), Bettina Schmidt (production design), Silke Franken (editing) and Stefanie Bieker (costume design) were responsible for the implementation. Dominik Diers was in charge of production
