Übung macht den Mörder

A dedicated teacher meets a brash commissioner with a stick up his backside – a detective duo that brings a lot of fun to the investigation! Isa Klein – in her early thirties, unmarried, childless, and a semi-ambitious teacher. When the dentist's wife is murdered in her Swabian village, it draws Commissioner Bähr from Esslingen into the case. Since the village of Grimmingen is so small that there are neither hotels nor guesthouses, Bähr promptly moves into Isa's holiday apartment. Although the curious teacher doesn't particularly like the outsider commissioner, she feels it's only natural to assist him in his investigations without being asked. While Isa's mother, along with her friend Renate, plans to finally set up her single daughter with a man (the commissioner), Isa gradually gets closer to the murderer despite some clumsy mishaps, putting herself in serious danger.
