Simon Eskenazy is a gay Parisian clarinet player who lives his single life to the fullest. One day, he receives a very tempting offer from his homophobic uncle, looking to continue the family legacy – if he gets married and has a child, he will receive ten million francs and inherit his uncle's luxurious mansion. After meeting Rosalie Baumann at his cousin David's wedding, and with some convincing on his mother's part, Simon sees an opportunity to fulfill his uncle's wishes and the pair go ahead and get married, but not before traveling to New York to meet Rosalie's Orthodox Jewish family. As Simon tries to develop real feelings for Rosalie, he struggles with his feelings for his newlywed cousin David.

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.
