Vitya is now not only the best farmer in the Arctic, but also a happy father. However, you will not be able to enjoy the family idyll again. At the personal request of the governor, Vitya becomes the mayor of Polyarny. Vitya is already not happy with the new position, and then it turns out that the previous mayor left behind a multimillion-dollar hole in the city budget. Vitya wants to resign, but when he realizes that he has crossed the path of an influential and dishonest businessman Lomaev, he decides to remain as mayor of Polyarny in order to save its residents from eviction from their own homes.

But trouble doesn't come alone. In the third season, Vita will meet Polina's mother, a retired literature teacher. However, even a new high position does not help Gromov to meet the high standards of his mother-in-law.
