This French film has a plot that sounds like an expansion of an urban legend. Walter (Daniel Mesguich) and Sara (Cyrielle Claire) are a married couple who have just moved into a new home together. Everything seems to be going well, despite Walter's fascination with a mysterious woman named Marie-Ange (Gabrielle Lazure) in a nightclub.
Then one night, running an errand for Sara, Walter finds Marie-Ange tied up in the middle of the road. He takes her to the nearest villa, hoping to contact a doctor, but he only ends up locked in a bedroom with her. In the midst of their inevitable passion, visions of Magritte paintings dance in Walter's head, for some reason.
In the morning, Marie-Ange is gone and Walter's neck is bleeding.
