The church bells are ringing, the sacristan is hanging from a rope. Walli tries to figure out who broke his neck. When the sacristan of St. Boniface Church in Burglbach is found dead, hanging from the church bell, Walli immediately considers the case closed – after all, it was clearly a suicide. Instead, Walli turns her attention to a much more intriguing question: with whom does Wolfi seem to be having a secret affair these days? Her son has been acting very strangely for quite some time. Only after the dead sacristan's young partner also disappears without a trace can Walli no longer contain herself. She immediately begins her investigation and stumbles once again into a wild adventure.
