Louise Bonì, Chief Inspector of the Freiburg criminal police, gets intelligence from an informer that two guns have been bought from a Russian criminal network. Desperate to prevent a fatal act of violence, Bonì is swift to investigate. Before long she identifies the vehicle used to collect the weapons, but the car's owner has a watertight alibi. The man driving that night was Ricky Janisch, a neo-Nazi and member of the extreme right-wing group, the Southwest Brigade. Bonì and her team put Janisch under surveillance, and identify others belonging to the extreme right. The further they probe, the more shocking their discoveries. Could this be part of a much more powerful neo-Nazi network which will stop at nothing? And how will they prevent an attack when the perpetrators are always a step ahead and they don't know the target?
