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.

Andula, an innocent Czech girl from a factory town, is desperately in search of love. She believes she's found it when she beds Milda, a charming young musician visiting from Prague. Milda, however, is only looking for a casual encounter, and leaves town assuming he'll never see Andula again. But when Andula doesn't hear from him, she packs up and heads to Prague, to the surprise of Milda and his parents.
