When Juliette Fontaine, formerly a doctor, is released from prison, her younger sister Léa invites her to stay with her family – including her husband, his mute father, and their two adopted Vietnamese daughters – in their home in the university town of Nancy, France in Lorraine (region). Why Juliette was in prison is revealed slowly throughout the film: first, that she was in prison for 15 years, then that her crime was murder, then that the victim was her 6-year-old son Pierre, and finally the reason why she killed him.
