Olga grew up in an orphanage because her mother at an early age has thrown her daughter and went to the north of the country. Now she has a new family, and does not need her grown-up daughter. But the trip to her mother helped the girl to meet with Roman, whom she married. Soon the immature young man left his wife, not knowing that she was pregnant. Years later, they meet again, but Olga does not want to forgive her husband, and Roman will bind to the jaunty collective farm boy, not knowing that it is his son.
