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.
