When the police arrive at the scene of the crime, a young woman is crouching next to the victim - apparently the murderer. She still has the knife in her hand and only wants to surrender on one condition: she demands to be able to speak to Inspector Faber. It is completely unclear what connection she has to the head of the Dortmund homicide squad. Then Commissioner Pawlak gets a disturbing call from his five-year-old daughter. On high alert, he makes his way to his family.
