Moscow, 1952, mid-October, the XIX Congress of the CPSU had just ended. A communal apartment on Bolshaya Pirogovka. In one of the rooms lives the Petkevich family: Ariadna with her husband Boris and her parents, professor of philosophy Peter Kazimirovich and his wife Angelina Fyodorovna. For those few months that remained until Stalin's death, the family experiences a series of dramatic events. But on a background of terrible time, antisemitism, fabricated "case of doctors", denunciations and snitches, there are people who live their lives without losing dignity.
In a nostalgic Moscow of 1976, an unlucky actor meets a charismatic writer, a living classic of Soviet literature, who turns his life into a tragicomic farce with the artistic bohemia, foreign-currency prostitutes, the KGB staff and agents of the CIA.
