The Ten Commandments, exact and uncompromising, literally cast in stone, continues to provide a source of moral conflict in contemporary society. In the ten part collection of films, The Decalogue, Krzysztof Kieślowski examines the dilemma of fundamental sin in the lives of ordinary Warsaw citizens.

"Zmiennicy" is a grotesque comedy of absurdity and reality that masterfully blends slapstick, satire, and surrealism to expose the absurdities of life under communist rule in the People's Republic of Poland (PRL). The story follows Jacek Żytkiewicz, a taxi driver in Warsaw, and his mysterious new shift partner, Katarzyna Piórecka, who disguises herself as a man to get the job. The series is a comedy of the grotesque, filled with exaggerated characters, nonsensical bureaucracy, and surreal plot twists. It mocks the inefficiencies and contradictions of PRL institutions—from corrupt officials and inept police to bizarre workplace dynamics and social hypocrisy. Underneath the absurdity lies a thriller-like subplot: a drug trafficking operation smuggling heroin from Thailand to West Germany. This storyline, featuring shady sports officials, a Thai student, and a crooked firefighter, adds a layer of intrigue reminiscent of American crime dramas.

The story stretches from 1863 to 1945. Its main characters are representatives of the Pasternik family, who live in the fictional village of Wielowice near Pszczyna. The protagonist of the first three episodes is Franciszek Pasternik, the following parts tell about the fate of his many children and even more grandchildren. The viewer follows their history against the backdrop of great changes and historical events that influenced the lives of Silesian Poles. So there is the Kulturkampf, Prussian rugi, the revolution of 1905, World War I and the Silesian Uprisings.
