Sudetenland, May 1945. A group of retreating German soldiers capture a group of young female workers, totally deployed in a chemical factory. He wants to use them as hostages during his advance to the American demarcation line. Together with them, they take refuge in a nearby castle, which soon becomes the site of the last battle that takes place both in the minds and in the backdrop of war-torn Czechoslovakia, shortly before liberation. A psychological probe as well as an intimate drama set within the walls of a small castle, it is a mosaic of mini-stories charting the fates, attitudes and thought processes of individual characters on both sides of the barricade.

Life in communist Czechoslovakia in the early 1950s and the punishments for going against the state.

The subject of this film, which takes an analytical look at the life of all of us with an analytical eye, is the evil microbe that has slowly infiltrated the organism of the Czech nation. Through the intertwining fates of three couples, it evokes domestic life before November 1989, burdened by a suffocating atmosphere of unfreedom, and after November, when relatively nothing has changed because people have not changed. The bleak conclusion suggests that the plague epidemic is still ongoing.

František Cepl is a young man from a simple family. He graduated from a real school and was going to study technology. When the occupation came, he had to work as a factory assistant. There he meets an older man named Telec, whom everyone knows as Hrabě. He impresses František with his ostentatious disdain for work and his shameless flirtation with women. František, whom the Count calls Papilio (butterfly butterfly), is filled with youthful ideals, while the Count, on the other hand, is an extract of the crudest individualism. He has worked his way up from a student at a business academy and a theatre actor to a member of a pre-war gallery. He blackmails, steals, drinks, abuses women and, in a way, Papilio himself.
