Summary Jakob's daughter Tammy is gone. She simply ran away in an inflatable boat. The search for her has two results: that Jakob has to find a way to get to his daughter, which Mechthild supports with words and deeds - and that the police have to solve the violent death of a wife and mother who is found dead in Lake Constance right next to Tammy's place of refuge. The victim, Verena Kirves, had arranged to go stand-up paddling with her friend Gülhan. But she didn't have time and so Verena was alone when her murderer strangled her. Husband Richard is stunned when Paul tells him the news. His daughter Emilia Kirves reacts differently than expected. And when Emilia seeks comfort from Gülhan's son Emre, it becomes clear that there are more connections between the families than the police are supposed to know. Julia exposes Richard as Gülhan's boyfriend. When Nele gets the data from Verena's cell phone, the police have to realize that they have followed the wrong lead. Suddenly cinnamon rolls play an important role and Lana del Rey provides the musical accompaniment to the showdown on the shore of the lake. Only Jakob, who has taken time off to play soccer with Tammy and to live up to his fatherly role, has a real sense of achievement. Tammy finally calls him "Papa". Then Tammy's mother Sonja calls. She seems upset. The line breaks down.
