''Entre Nous'' tells the story of two young married women in the 1950s who don't recognise how unfulfilled they have been in their marriages until they meet each other. In the preliminary scenes, set in 1942, Lena (Isabelle Huppert), a pretty 18-year-old, has been arrested and brought to an internment camp for Jews in the Pyrenees. One of the guards, Michel (Guy Marchand), writes her a note warning her she may be deported to a German Nazi camp, and offers her marriage as a means of escape. She accepts. During the marriage ceremony she discovers that he too is Jewish; she's dismayed to learn that she won't have the protection of a gentile name.
