When the police arrive at the scene of the crime, a young woman crouches right next to the victim - apparently it is the murderer. She is still holding the murderer's knife and only wants to surrender on one condition: she demands to be able to talk to Commissioner Faber. It is completely unclear what connection she has to the head of the Dortmund homicide squad. Then Inspector Pawlak receives a disturbing call from his five-year-old daughter. On high alert, he sets off for his family.
