Early 18th century. Cartographer Jonathan Green undertakes a scientific voyage from Europe to the East. Having passed through Transylvania and crossed the Carpathian Mountains, he finds himself in a small village lost in impassible woods. Nothing but chance and heavy fog could bring him to this cursed place. People who live here do not resemble any other people which the traveler saw before that. The villagers, having dug a deep moat to fend themselves from the rest of the world, share a naive belief that they could save themselves from evil, failing to understand that evil has made its nest in their souls and is waiting for an opportunity to gush out upon the world.

Jurácek's feature debut is shot in two parts. In the first, a corporal accompanies a new recruit with a sore Achilles tendon for his physical, and all the girls or young women they see are played by the same actress (Ruzickova). In the longer second segment, shot with the help of the Czechoslovakia army, the soldiers pass the time during basic training and maneuvers by talking about girls.

The fates of the women are repeated: the 16-year-old daughter of a 32-year-old mother is also pregnant. Like her mother, the child remains unmarried and fatherless. From him, the girl receives only an exotic postcard with the titular three camels...

Czechoslovakia, 1941. As the war continues, Reich Protector Reinhard Heydrich arrives in Nazi-occupied Prague and establishes a regime of terror that will force freedom fighters to act. But the price to pay will be too high.

Operation Danube was the cover name for the invasion of Czechoslovakia by Warsaw Pact armies in August 1968. The fleet of Polish tanks which arrive to liberate their neighbor, ostensibly threatened by a counter-revolution, includes the old tank nicknamed Ladybird, which is the last to leave the barracks.

It is 5 May 1945 and the uprising against the hated German occupiers has broken out in Prague. The Czech guards open the gate of the Pankrác prison to allow the prisoners to escape en masse. Many of them are shot dead by the German guards but young Ruda (Jaromír Hanzlík) manages to run away. He is taken care of by one of the Prague fighters, concierge Kytka. Kytka hides him in the flat of the house's owner where only the young maid Karla (Jana Brejchová) is left, ordering her to take care of Ruda.
