Every parent wants to be proud of their child. But the Litvins were tired of being ashamed of their Boria's actions. The fact is that now Borya is Boris Valentinovich and he is the mayor of their city, and among the people he has a stable reputation as a “thief”. Having learned that the thieving mayor is going to run for a second term, mum and dad decide not to wait and install him themselves - in the children's room... behind a thick grid. Thus, an isolated forest house on the outskirts of the city will be transformed into a secure establishment, where the parents will try to analyze and correct their pedagogical errors together in order to put the mayor back on the right path.
