Oh, holy moly! Village policeman Jupp and his Inge find the neighbor in the bathtub. Naturally naked - still not a pretty sight. She lies dead in her bubble bath, and for the criminal investigation department, everything is crystal clear: the singer from the local church choir (front row, center) preferred to sing with the little angels in heaven - voluntarily! However, Jupp and his wife suspect murder and start snooping around the life of the deceased. In the process, some neighborhood secrets come to light. And on the personal front, there are dark clouds as well: Inge is pressuring him into couples therapy to save their troubled marriage. Meanwhile, mother-in-law Käthe suffers from chronic stubbornness and does whatever she wants. Suddenly, more church choir singers start dropping like organ pipes. Detective Jupp suspects that something is seriously amiss. A tough investigation is needed in the Backes family.
