Luděk Krejza, a tile-layer, returns from prison after serving time for manslaughter. In a retrospective, the viewer is introduced to his story. It is a not very well-known film, which with the passage of time has completely disappeared from the awareness of even the more deeply informed interested in domestic cinema. The song "Dudes, you're on" is sung by the Yo Yo Band.
