When Chief Inspector Carsten Kantner plans a romantic weekend with his girlfriend in Altenberg, he hasn't counted on his sister Sophie. With her unpleasant surprise, she thoroughly ruins his mood. And then she also finds a body in the fairy tale forest. The identity of the deceased is quickly established: Oliver Wolf, a tax officer from Wuppertal. But who had a motive to kill him? Meanwhile, a murder also casts a shadow over the sunny summer weather in Wuppertal. A young woman has been found dead in an apartment. The apartment of the victim from the fairy tale forest. Pure coincidence? While Carsten Kantner and his team, along with colleagues from the Cologne police, work to solve the mysterious cases and uncover increasingly dark secrets, Sophie Liebermann once again goes her own way. And that leads her straight to the next crime.
