Czechoslovakian crime film

A car deliberately runs down a young man on a road by a small border town. The locals recognize the dead man as one of the students who were there on volunteer work some time before. The police detectives, Major Kalas (Rudolf Hrusínský) and Lieutenant Varga (Radoslav Brzobohatý) can then get on the trail of the people with whom the victim was involved, especially at the photographic studio headed by Bohuslav Pacer (Bohus Záhorský).

Shortish forty-year old Ludvík Podzimek, lute and flute player in a Prague orchestra, is far from being an attractive man. He is nevertheless generally considered a great 'Don Juan'. Women take up with him out of a certain motherly compassion and Ludvík's tender heart does not allow him to split with any of them. His lovers thus accumulate and cause him numerous troubles.
