Blind luck ties the fate of two people together.

The head of the nunnery is dying, and the members are divided in two groups as the election of the new head approaches. Led by Virginia, the younger nuns stand up for changing the strict religious dogmas and would like a modern school with genuine science, a bathroom to be built, and a freer spirit. Their candidate is sister Magdolna, who went to secular universities, too. The seminarists, led by Király Erzsi, also rebel against the older nuns' strict discipline and the depressed atmosphere of the institution. However, Magdolna does not want to stay involved in the fight because she is deterred by Virginia's sinful attraction towards her and the tools Virginia is using to gain victory at any price.

Savanyú and his friend work at a plant. After the monotonous shifts they engage in the pleasures of the afternoon and the night, i.e. parties and concerts. Savanyú dates Juli, they are already engaged. The young men live as sub-tenants, the young women in workers' hostels. None of these places are suited for spending time together. They are in need of an apartment. Out of the ruinous apartment which they lay siege on, however, they are sent away by the otherwise friendly policeman. At a concert held in the Park of Youth, Juli gets to know Géza. They flirt, then go to the country with a pop-group. Savanyú and his friends follow them. A minor fight cools the atmosphere.
