In her new case, Vera Lanz is not only challenged professionally. The investigations are also putting pressure on the tough policewoman in her private life. The assignment is more than inconvenient for Vera Lanz. Instead of meeting up with Dominik Schneider for one of the rare rendezvous, she is picked up by Paul Böhmer to a crime scene. The drug dealer known to the police, Rolf Hüske, was murdered. At the scene of the crime, Vera meets Veit Mahn, a colleague and friend of Trompeter who reported the murder. Schneider is also on site. He is investigating internally against Mahn, who is suspected of having embezzled cocaine during a raid.
The results of the forensics make the case even more complicated: In Hüske's shelter, traces of a female person are secured: Did the young, drug-addict Jessica Winsler shoot the dealer? The investigation of the ammunition brings unexpected movement into the investigation: The associated weapon is registered and belongs to none other than the internal investigator Dominik Schneider.
