Inspector Murot (Ulrich Tukur) is engaged in a conversation at a hotel bar by a younger woman (Anna Unterberger). Over a glass of red wine, Murot plays with her and cheerfully pretends to be an insurance salesman. The next morning he wakes up in his hotel room with no wallet and no memory of what happened. Murot hides from his employee Wächter (Barbara Philipp) that he has been robbed by a con artist. But Wächter is already watching him suspiciously, because that same night a high-ranking IT expert (Dirk Martens) was found murdered in the hotel. There are suspicions that the con artist is involved in the murder and disappearance of a high-risk laptop.
While Wächter is busy investigating the case, Murot is confronted with his past: the young woman has wormed her way into his life and is forcing Murot to reconstruct incidents that happened many years ago on a holiday trip. Murot is overcome by the fear that he has taken the guilt on himself.
