100 years ago, the Russian Empire ... Christmas Eve. December plugs, holiday celebrations, balls and modest luxury holidays, titled nobles and ordinary peasants, the royal family and the soldiers of the First World War, progressive poets and the first skaters - everything was different, except ... the holiday. People prepared, lived, believed dreaming and waiting for this miracle - Christmas!

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.

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.

New Year's adventure of a little Christmas tree girl.
