While target investigators Nora Weiss (Anna Maria Mühe) and Jan Geissler (Peter Jordan) are celebrating the success of a successful mission, they are visited by Bavarian local politician Monika Landau (Katharina Müller-Elmau), who is on vacation at the Baltic Sea and misses her husband. When his body washes up on the beach the next day, Nora and her colleague Simon Brandt (Jan Krauter) of the Lübeck homicide squad begin to look into the dead man’s life and surroundings to find a “clue.” A clue as to what might have happened to him.
One lead finally takes the investigators to Güstrow, in the former GDR. There, Maik Wosniak (André M. Hennicke) seems to be hiding something, which is why he sets his dog on the investigators and manages to escape from them in a breakneck chase. But with him, Nora has found a “toucher.” In old Stasi files, she finds out that the fugitive was in GDR prison at the time, while Patrick escaped from the GDR – on a sailboat. Parallel to the investigation, Nora’s father, Pastor Rainer Weiss (Rainer Bock), is to receive an award from a human rights association for his activities as an escape agent in GDR times. Nora has a terrible suspicion: did her father play a completely different role than he claims?
