The Irony of Fate

A group of old friends have a tradition of going to a public bathing house on New Years eve. Incidentally, too much vodka and beer makes two of them unconscious. The problem is that one of them (Sasha) has to go to Leningrad but another one (Zhenya) goes. Zhenya wakes up at Leningrad airport. Believing that he is still in Moscow he takes a taxi and goes home. The street name, building and even apartment number, the way an apartment complex looks the same and the key coincide completely - just typical Soviet-type 'economy' architecture. Imagine the surprise of Nadya when she enters her apartment and finds a man without trousers in her bed. What's more - Nadya's fiancé also finds him there...

Events unfold 30 years after the events of the movie "Enjoy Your Bath". The plot is as follows: Zhenya and Nadya did not get married, and each returned to his own life - Nadya to Ippolit, and Zhenya to Galya. The main characters in the new film are the son of Zhenya and Galya - Kostya, and the daughter of Nadya and Ippolit - also Nadya. On New Year's Eve, Kostya Lukashin returns from a medical conference from St. Petersburg to Moscow, having thoroughly drunk, Kostya thinks that he is already in Moscow.
