Signe Charlotte on AllMovie

In a most unusual, near menage a trois, Charlotte (Isabelle Huppert, sister of director Caroline Huppert) is a terrified young singer who is forced to hide out at the home of her ex-boyfriend -- her current male companion has been murdered in his apartment, and she fears the worst. The trouble is that Mathieu (Niels Arestrup), her ex, is happily living with his new love Christine (Christine Pascal), and Charlotte's presence totally unnerves him and upsets Christine. Yet he agrees to hide her above their garage. That arrangement does not last long, and Charlotte shortly disappears on them, only to call Mathieu for help a few days later. He zooms off to her rescue, but even Christine, intensely hurt by Mathieu's behavior with Charlotte, agrees to help the duo cross over into Spain. Before that plan can be put in place, Charlotte is gone again -- leaving Christine and Mathieu to patch up the wounds in their relationship, which faces an uncertain future.
