In Wahrheit - Still ruht der See (2019)

Detective Chief Inspector Judith Mohn is supposed to have the day off, but a missing-person report for a 16-year-old boy makes her cut short her fishing trip. His mother Kathrin Brandmann’s fears prove justified, and the boy is found dead in the lake. The first people Mohn looks into during her investigation are the boy’s friends, who are very reticent about Marlon and their relationship with him. Only Lukas is talkative and visibly shaken by his friend’s death. According to him, Marlon had recently met with Sharif Masmoudi. Judith Mohn and her colleague Freddy Breyer look into this, and after discovering that Masmoudi deals in counterfeit designer trainers, they suspect this may have been the motive for the murder. But the suspect has an alibi. The investigation therefore turns to the group of friends, among whom Marlon was an outsider. The group is led by Florian Berger, who has everyone call him “Number Six.” Judith Mohn soon finds out why. The boys had a kind of competition to see who could sleep with the most girls. Marlon had not taken part and had even stood up for the girls. It appears that Florian Berger had not won over his sixth girl voluntarily: he had raped her in front of all the other members of the group. Marlon was the only one to protest, which is why everyone called him a traitor. Berger even calls him “gay” and gives that as the reason Marlon was an outsider. Mohn picks up on this and initially suspects that Marlon’s father could not accept his son’s sexual orientation. But Karl Brandmann accuses Marlon’s friend Lukas of seducing his son, and has an alibi for the time of the crime, so Mohn wants to speak to Lukas. She finds him by the lake where Marlon died. Lukas seems distraught. He tells her that Marlon had said he was in love with him. They had argued because of this, and Marlon had fallen headfirst onto a rock. Since he was no longer moving, Lukas pushed him into the water. Mohn takes Lukas to the police station so he can repeat his statement there. Nesrin now also finds the courage to report the rape. Detective Judith Mohn grew up in the former miners’ settlement near the French border where the victim lived, and, after 20 years, visits her mother for the first time. Their meeting is not at all warm. Mohn reproaches her mother for preventing her from going to university so that she would stay in town and with her. Without a degree, Mohn had to struggle her way into the higher civil-service ranks, but she managed it.
