Raisa wants to take revenge on Albert for his betrayal and form an alliance with Vitya. But there is only one problem – when she wakes up, she realizes that she is not in Polar. And not even in Russia. Albert is preparing to storm Vitya's farm with the help of special equipment. But Vitya and the other heroes do not intend to give up without a fight. Who's going to take it?

The mayor of the city of Polyarny dives into an ice hole at the celebration of Walrus Day... and does not come up. At the personal request of the governor, Vitya takes a vacant place in the administration and gets acquainted with a visiting investor by the name of Lomaev. Irka is trying to get Tolya a job. Polina's mother, Antonina Vasilyevna, is coming to Polyarny. Which manages to make an indelible impression on Nemolyaev.

Vitya calls Raisa to help him and finds out that the former mayor left behind a multimillion-dollar hole in the budget. In search of a solution to this problem, he turns to Lomaev for help and finds out that he planned to demolish the city for the sake of his own business project. Vitya decides to stay in the mayor's chair and fight for the Polar to the end. Tolya and Kolya are doing repairs in Irka's apartment. And Antonina Vasilyevna arranges a debauch in kindergarten.
