L'ironie du sort. La suite

Thirty years have passed since Zhenya and Nadya met—they broke up, and Nadya moved to Leningrad. The friends still go to the bathhouse, and now they are joined by Konstantin, Zhenya's son. Uncle Pasha and Uncle Sasha persuade Kostya to arrange a New Year's miracle for his father and send him to St. Petersburg. Nadya's daughter lives at that very address, and on the same day, her fiancé, Irakli, is planning to propose to her.
