A body lies on a boat, a suspect runs away with the murder weapon in his hands, and there is evidence of robbery at the scene: Klara Blum's new case seems clear from the start. The prosecutor signs the arrest warrant without hesitation. With a confession from the suspect, the case would be complete. But Daniel Seefried denies the murder of the rich industrialist Wolfgang Reichert. He looks dazed and thinks he has been anesthetized. He himself did not know how he got into the ship and the knife. Difficult to believe and even more difficult to prove. Klara is suspicious of Seefried. But she is also irritated. Because in Seefried's telephone storage there is the number of Rita Fürmann, the wife of the public prosecutor.
