In France, a gendarme is murdered. The suspect is an old acquaintance of Eva and Wolfs, a neo-Nazi who has worked as an informant for the police. Wolfs and Eva seek out the leader of the neo-Nazi group who has now served his sentence. When it turns out that former informant left a manifesto announcing a mass murder after the murder, all alarm bells go red. Marion and Romeo are called to a house in a dispute. This turns out to be murder and mayhem.

A heart surgeon is found shot dead in a house that cheaters can rent for their meetings. Was it a vulgar home robbery that killed him or did adultery have something to do with it? Marion tries to keep functioning, but turns out to be too affected by the earlier events.
