Louise Bonì, chief inspector of the Freiburg criminal police, receives a tip from an informant that a man has purchased two pistols from Russian criminals. Concerned, Bonì investigates to prevent a possible violent crime. Soon, she finds the owner of the car used by the buyer to pick up the weapons. However, he has a watertight alibi for that evening. The driver was someone else - Ricky Janisch, a neo-Nazi and member of the far-right Brigade Southwest. Louise Bonì and her team begin to observe Janisch and uncover more intermediaries, all of whom belong to the right-wing scene. The deeper they dig, the more alarming the scenario becomes: Are they dealing with a far-reaching neo-Nazi network? And how are they supposed to prevent an assassination when their opponent always seems to be one step ahead?.
