Happy Birthday Sep 17, 1962

The plant director gathers all the young people in one shop, entrusting them with both work and management. The experiment is unsuccessful, as the youth workshop did not become a collective. Young engineer Sergey, who heads the shop, realizes that only by uniting the youth, he will be able to work fruitfully and fight against marriage and indiscipline. Tsybulkin, who was chosen as a Komsorog, helps to realize the plan conceived by Sergey,. Two schools come to internship. One of them - Lisa Gromova, the daughter of the director of the plant. The shop staff and Sergei undertake to re-educate the maiden spoiled by her mother. Director Gromov himself helps them.
