A series of murders shakes Frankfurt. Three men were shot in the neck, and there was no connection between the victims. Since there are two "non-Germans" and one homeless person, one suspects a perpetrator from the right-wing milieu. But Commissioner Murot from the LKA Wiesbaden has a different suspicion. He believes that the two first murders were only intended to make the whole thing look like a series of murders, while the perpetrator was really only interested in the third victim: Jochen Muthesius. The homeless man was a former philosophy professor with whom Murot also studied. At a time when dreams of a better world and the "principle of hope" were still alive. It was different for Muthesius. After a family tragedy, he had lived on the streets for years. And yet he still owned a villa in Kronberg and a considerable personal fortune. So the three children of the deceased come into the focus of the investigation: Paul, an eccentric solo entertainer. Inga, a psychotherapist. And Laura, who used her father's money to set up a foundation for the needy. While Murot's assistant Wächter is more and more convinced that Murot is getting lost, a new suspect appears: Jürgen von Mierendorff, neighbor's son and friend of the Muthesius family, but now part of the right-wing scene. When Murot realizes that several of the suspects are in league with one another and that he only has a chance if he plays them off against each other, he goes on the offensive: to lure them out of the reserve, he tells them to kill him .
