In the forest near the village of Drahovice, a nurse from the local health center is found murdered. Three months ago, another young woman died nearby and a sexual motive was proved in the case of her murder. In the case of the nurse, the motives are not so clear. Two criminologists from Prague - Major Kalas (Rudolf Hrusínský) and Lieutenant Varga (Radoslav Brzobohatý) - patiently collect all available leads and question the villagers.

The heroes of the small-town story are former friends Standa Stuchlík and Robert Sura, who become arch enemies, and not only because of their classmate Zuzana, whom they both like. While Robert, the dude, has rich parents who spoil him and buy him everything he asks for, Standa has to earn a hard living playing in a rock band, working part-time in the boiler room and constantly defending his hobby against his parents' disdain. His only support is his uncle Edda, also a musician.
