Chief Inspector Mark Brenner wakes up in the morning to find his lover dead in the living room - strangled with his own tie. He cannot remember anything, except that they had a quarrel the night before. His wife Kathrin, an ambitious politician, is on a weekend trip with their two children. Brenner is aware of what he has to do in order to save himself, his family and his career in the Berlin police department. He disposes of the body and covers up his tracks. Brenner thinks he has full control over the situation - until a call arrives from his colleague Pia. In the heart of the city, a woman’s dead body has been found. When arriving on the crime scene, his worst fears come true. It is the body he had buried far away in a wood. He takes over the case together with Pia and young Simon Gerlach and has to play his role as a cunning police investigator hunting a murderer. His colleagues’ mistrust rises, however. Brenner seems to be the victim of a perfidious plan, a perfectly staged campaign of revenge. Someone is always one step ahead of him, someone who knows what he has done.
