Enquiries into the murder of a young woman take the private investigator Peter Keller to the idyllic village of Schwant in Emmental. But, the more entangled Keller gets in the treads of the apparently clearcut case of sex murder, the more obvious the flaws in the village idyll become. Keller's quest turns into a deadly mission.

The trial of the case, which has become known under the catchphrase "Murder in Kehrsatz", triggered a great deal of public sympathy and, after the verdict, considerable protest. This came out primarily from a jury member of the process. She, a housewife and SVP member, began to have more and more doubts about a judiciary that apparently no longer works according to the principle "in the case of doubt for the accused". The film tells the story of these jurors during the long trial.
