In 1920s Munich, homicide detective Axel Berg is called to the scene of a grisly homicide, the victim being a young society wife. Soon, a second body is uncovered; the discovery of a third indicates that Berg is dealing with an unimaginably evil killer. In the Germany of the time, the investigation cannot be straightforward. Hitler's power is growing, and the Nazis are a strong civic force in the city of Munich. Berg is thrown into a web of danger as senior officers work to their own agendas.
