In the forest of Hablikon, the administrator Reichle is found shot dead. He had gone hunting with three other respected citizens of the community. Detective Sergeant Müller takes charge of the investigation.

With no clear motive, Müller focuses his attention on the honorable and irreproachable fellow hunters. Their clean facade begins to crumble during his investigations. Village doctor Amsler, banker Meier, and architect Häuptl all had something to hide. Reichle knew about their private and business misdeeds.
