Murot - 4 - Im Schmerz geboren

A lonely train station, three men with guns, one man gets off the train alone. Suddenly the three men are lying dead in the dust, but the other man hasn't shot - "Guard, something's wrong here!" When Murot recognizes the man on the video surveillance, who is not the murderer, he fears disaster. It's Richard Harloff, his ex-best friend from police academy. The two were once in love with the same woman, with whom they engaged in a "ménage à trois" as in their favorite film, Jules et Jim.lived together. Harloff was then suspended from the police service because of a drug history and disappeared with his wife to South America 30 years ago, where he became a super gangster in the following years. It quickly becomes clear that Harloff is on a vendetta with his son. More murders happen.
However, Harloff always has an alibi. Murot is desperately trying to stop the series of murders, but has no idea that he is actually the target of a diabolical plan.
