A broken railing, a strangely twisted body on the slope. Ariane had just wanted to remove a sexist graffiti on her first day of work in the Harz Mountains, after all, that was part of her duties as a sensitivity manager for the tourism association. When Police Chief Inspector Andreas arrives at the scene with his dog, two things quickly become clear: Ariane and Andreas are like fire and water, city and country, tofu and sausage, beer and kombucha. Instead of making the Harz more diverse and inclusive for everyone, Ariane faces entirely new challenges – because someone is causing people to die. The dead body in the forest won't be the last. So much for "Good luck" in the Harz. Andreas and Ariane investigate. And the dog, too.
