Felix Murot and Magda Wächter are called to the parking garage of a casino in Wiesbaden in the morning where a dead man was found in a stairwell. While securing evidence, Murot discovers another body in the trunk of a car. He finds out that one of the dead had just won a large amount of money, but the money has disappeared. Was it really all about money or is there more to the murders? Then it happens: Ulrich Tukur himself is suspected of murder. A film within a film. Tukur, who plays Tukur, quickly realizes that there are no loyalties in the film industry. But he also poses other questions related to the nature of cinematic illusion and his own role in the hilarious game of genre contradictions, a self-reflective game in which the main character spins around himself in interesting turns. What is it actually like when you play a commissioner, while you are actually Ulrich Tukur, although you are only playing him here? "Who am I?"
