A man is found brutally murdered in rural Lower Saxony: Arash Naderi migrated to Germany from Iran just a few months ago. For the investigators Julia Grosz and Torsten Falke there are some indications that it could be a politically motivated murder; the dead person may have fallen victim to a right-wing act of violence. As Falke and Grosz quickly discover, Arash Naderi was indeed harassed in the period leading up to his death. Namely by farmers from the area, whose ringleaders have often come into conflict with the Office for the Protection of the Constitution. He regularly hosts meetings in his barn and is known to stir people up. Falke and Grosz soon find out what these conspiratorial meetings are about.
The farmers turn out to be militant environmentalists and plan campaigns against fracking. It is becoming increasingly clear that it was not his background that made the victim a target, but perhaps his job. Arash Naderi worked as a driver for a natural gas company.
