Jerzy Zalewski

Franek, a petty criminal and gambler, befriends Rysio, who performs inspections of meat plants. Rysio suspects wrongdoings at the slaughterhouse. Franek, despite his age, cannot find a place in life, with nothing achieved and, what's more, still not knowing what to do.

Jan and Maria meet at a party and are immediately drawn to each other. Their difficult financial situation and the scorn of society inflicted on them push them to a breaking point, culminating in a string of murders.
