Plot synopsis: Mid 20th century. Industry is developing rapidly and the need for workers in factories is growing. After graduating from the tenth year, Viktor Chernyshyov, now a city dweller, did not bother to continue his education and went to the plant as a turner. He considered it quite normal that the guys enthusiastically listened to the stories of his peer Kolya, a lounger who boasted of victories over women, and participated in his dubious amusements. Only one of them, Pyotr — a real worker, a doctor, tried to reason with Kolya and the others.
