In the bone collection at the Anatomical Institute of the University of Würzburg, a young doctoral student discovers a skull that doesn't match the rest of the skeleton with which it was filed. The skull is significantly younger than stated in the death certificate. That same morning, twenty-year-old Steffi wants to complain to her mother for not waking her up. But Andrea Schwinn is found strangled in the parlor of the inn that the family has run for generations. Her father, Holger Schwinn, is nowhere to be found. One of his hunting weapons is missing. While Chief Inspector Felix Voss and his colleagues, Chief Inspector Paula Ringelhahn, Inspectors Wanda Goldwasser and Sebastian Fleischer, and the head of forensic science, Michael Schatz, begin their investigation at the inn, an elderly woman pitches a small tent on Jakobsplatz directly in front of the Nuremberg police headquarters because she cannot accept the police's refusal to take action in the case of her missing adult son.
