Sister My Sister plot
The sisters Christine and Léa work as maids for Madama Danzard and her daughter Isabelle. Madame Danzard is cool, dominant and strict. She treats her adult daughter Isabelle like a toddler. She has a real reign of terror for her staff. Christine and Léa were brought up without love in a nunnery and seek the tenderness and love that had been missing for so long. This creates a passionate sexual relationship that is overshadowed by fear and frustration. And Madame Danzard's well-oiled household is beginning to show more and more cracks. On a desolate February afternoon, a confrontation between the four women leads to an unavoidable act of violence.
