Michenbach, a small village in the Harz: 4-year old Clara Tomrad disappears on her way to school. The police quickly find a suspect: Hans Kortmann, who has been in prison because of the murder of a 15-year-old girl, doesn’t hide his affection for young girls. And it seems that he is hiding information. Detective Inspector Steffen Gellhagen from Hannover is recruited to help solve the case. It was him who convicted Hans Kortmann at the time. But Kortmann is not a normal opponent. He is looking for payback and ready to take vengeance. A perfidious game is about to begin in which Kortmann always appears to be one step ahead of the police – as time for Clara is slowly running out.
