This bright domestic drama captures a moment in time when, for a large number of idealistic and grateful French men and women, the promise of Russian communism was bright, and everything Russian was a source of joy and amazement. In the story, Irene was rescued from Auschwitz by soldiers from the U.S.S.R., and since that time she has enthusiatically considered Russia to be the source of hope in the world. Her more pragmatic husband has, by 1958, grown somewhat weary of her enthusiasm, which has led her to decorate their apartment with anything Russian she can get her hands on. Matters come to a head when she is befriended by three members of the Red Army Choir during their tour of Paris.

En 1958 en plein référendum pour l'adoption de la Constitution de la Ve République française, la vie quotidienne d'Irène, militante communiste qui a été sauvée des camps de concentration par l'Armée rouge quand elle était jeune, et qui est mariée à Bernard, petit commerçant gaulliste. Leurs divergences d'opinions politiques mettent à mal leur couple, sous le regard de leur fils et du frère d'Irène qui vient souvent chez sa sœur. Dans ce moment historique, les Chœurs de l'Armée rouge viennent donner une représentation en France, ce qui permet à Irène de rencontrer des vétérans de la bataille de Stalingrad sous le regard jaloux de son mari. Elle fera tout pour convaincre ce dernier de voter non lors du référendum...
