Investment banker Ann-Kathrin Werfel is cruelly killed. The first suspicion falls on her ex-husband, whom she had accused of domestic violence. Patrick Werfel, however, presents the inspectors Lena Odenthal and Johanna Stern with a well-attested alibi. Clues from where the body was found lead the inspectors to Hajo Kessler, who is a soldier in the Bundeswehr. Kessler states that he did not know Ann-Kathrin Werfel , but his car was seen near the site. In the survey, he is correct, almost charming. But he's prone to freaks out - and they seem to have something to do with the fact that it's women who are questioning him. The evidence is thin. But Lena Odenthal is convinced that the suspect is simmering with the deep-seated hatred of women that led to Werfel's murder.
