The brother and sister, Pyotr and Olga Ivanov, are absorbed in the routine of everyday life. Pyotr has a family, unruly children, and a job he doesn’t love, while Olga is having an affair with a man who is completely unsuitable for her. Suddenly, their father, with whom they haven’t communicated for many years, bursts into the Ivanovs’ dull everyday routine. Ivan Ivanovich likes to repeat the family motto: “We are the Ivanovs! Everything depends on us!”, but the family is far from being called ideal. The large family will have to go through many comical and dramatic situations in order to restore their relationships.
