Olga Nikolaevna is a strong-willed woman and the head of the housing and communal services, who is quite happy with her life. She is the mistress of the house and at work, completely controls her husband Roman Pavlovich and protects her daughter Varya. The only one who does not fit into her happy picture of the world is her son-in-law Victor, from whom her beloved daughter is due to have a child one of these days. And then one day the barrage of mutual claims becomes so great that right on a family holiday the situation gets out of control.
