1950 film by Miloš Makovec

Karel Doležal, insurance clerk and exemplary father of a family, leaves for a business trip with his secretary Vlasta. After spending the night together, they both return home. However, thanks to a small moment of inattention, they run over the boys. Karel runs away from the scene of the crime. He won't tell anyone what happened. Then when he reads in the newspaper that the boy did not survive the accident, he begins to feel guilty. He confides in his wife about the accident, not the infidelity. Their son Jirka overhears everything. His father has always been his role model, and that's why he doesn't want to accept his guilt.

The protagonist (Rudolf Hrusinsky) is a dull, fat, shy government clerk indulging in voyuerism and ego fantasies. In love with another clerk (Kveta Fiolova), he is urged on in his pursuit by a commiserate executive. The story is told in a flashback sequence as the cuckolded Hrusinsky attempts suicide by gassing himself in his bathtub. The "Murder" of the title is not a murder as such, rather the murder that Hrusinsky remembers planning upon discovering his wife's unfaithfulness with his supposed friend and advisor. Both plots failing in his mind, he loses himself in fantastic reveries of his funeral and of hypocritical mourners. ' Deciding (perhaps) that this is not the way out either, he gives up the attempt and imagines a life of reconciliation and eventual affluence.
