Caroline (Maria Casales) and Isabelle (Simone Signoret) are half-sisters with a long history of mutual animosity. Jacques (Jacques Berthier) is Caroline's lover, who jilts Caroline for her pianist half-sister Isabelle while Isabelle recuperates from a nervous breakdown. The envious Caroline tries to win Jacques back by forcing Isabelle into another emotional collapse. There may be a happy ending resulting from all this, but one would never know it from the murky photography and overwrought acting. Of the stars, Simone Signoret comes off best, making the most of a difficult and contradictory role.
