Cheerful provincial Vera and a responsible doctor from an intelligent Moscow family Igor marry for great love. Their union is not approved by Igor's mother and younger sister, Emma Petrovna, and Zoya believes that Vera is no match for him.

Living with three women under one roof leads to domestic conflicts. Emma Petrovna and Zoya declare war on Vera. Everything is used: from minor quibbles to Igor's fake date with a "worthy" girl. The situation is aggravated by the news about Vera's pregnancy. Realizing that there will be no peace in Igor's family, Vera lies to him that she lost her child and is leaving. Igor becomes depressed due to separation from his beloved, and his mother and sister try to rectify the situation by returning Vera. But Vera is no longer sure whether she needs such "family happiness."
