The story takes place during World War II and presents the illegal movement from inside. Some tough guys from the square have been angry with Albert Zoli, a boxer since he started living a decent life, passed the final examination at high-school, and entered a job as a bank clerk. About his illegal activity, however, they do not even have the slightest idea. With the help of Zsizsi, a young actress, and Diogenes, an extravagant tramp, he persuades the guys to join the movement. They distribute anti-Nazi handbills and paint pacifist slogans onto the walls of houses.
