Julian is a psychiatric patient and wants to walk from Berlin to southern Germany. He believes that through the power of walking he can heal his friend's father, who has died of a heart condition. First, he runs into Ju, a young doctor, who he soon meets again by chance. She feels unhappy, searches for her heart and spontaneously joins the likeable dreamer on his way to Tuttlingen, where the sick man lives. In a tourist resort, they are joined by a frustrated wife and mother.

Bente, a school dropout, was a foster child on the Strand family's remote farm. Forensic medicine finds a key in Bente's stomach. Where was the girl going with two cans of gasoline? Why did the local gas station attendant sell her gasoline even though it was known that she was an arsonist? Which lock does this key fit into? Local policeman Lars Klapproth might be able to contribute to solving the case, but he does not. Because Lars is the father of Maria's missing daughter Matilde. He had made the toddler disappear with the help of GDR state agencies during the reunification period. When Maria, who had fled the republic, returned to get her daughter shortly after the fall of the Berlin Wall, Matilde had already been adopted and could not be found.
