Great excitement in Flensburg. The body of Hark Ole Harmsen is found on the beach with gunshot wounds. The secretary of the Kiel Ministry of Economic Affairs was considered the rising star of his faction. Quickly, a party colleague of Harmsen comes under suspicion, as the victim's fiercest rival can hardly conceal her joy over the death of her arch-enemy. Due to the political sensitivity, this is a delicate case for the newly promoted chief inspector Helene Christ. To make matters worse, she has to deal with a new superior: Jasmin Brenneke comes from the LKA to Flensburg and sets her own priorities there. At least Helene can count on the help of her former colleague Edgar Schimmel and her friend Simon Simonsen. She needs it urgently, as she soon risks sinking into a swamp of political trench warfare and ruthless intrigues.
