When a Man is Around(1978)

Dina is 32 years old. She is a brilliant surgeon, works in a maternity hospital, and lives alone with her sister Marga. Once in the hospital, a woman refused a child. Dina adopted a baby, and unexpected troubles changed the lives of both sisters. Meanwhile, the conscientious Marga, secretly from Dina, began to look for Seryozha's father — what if they rushed to adopt, because the father knows nothing about his son. And soon Dmitry Savich began to visit their house often. He had actually met Seryozha's mother once and was now ready to take an active part in raising his son.
