When the gravedigger wants to dig the grave for the deceased Mrs. Häberle, he experiences a nasty surprise: the supposedly free burial plot next to the deceased's husband is already occupied. In the coffin lies the body of the former mayor of Glückhausen, who left the town two years ago. Inspectors Zondler and Aichele try to get to the bottom of the case. Why is the former mayor in this grave, and above all, who put her there? She had not been popular, as the investigators soon discover in their conversations. Various intrigues come to light. Only slowly do one or two clues emerge. It takes several hearty visits to local taverns by the two inspectors before they can solve the case. A Swabian crime story with sharp humor and plenty of local color.
