In 1947-48 a group of the NÉKOSZ youth conquers a church secondary school and provokes discussion with the students there on the validity of Marxism. They improvise dances and choirs on the yard, when a police officer wants to arrest a few Catholic students. Laci, who stands for the clever, democratic persuasion, renounces. Power will be taken by two sectarian girls: Teri and Jutka. They force the priests to take off their clothes, they throw books out, break windows. When the leadership of the movement arrives, they denounce the extremist conduct and excommunicate the two girls.
