What a taut drama telling us the story of a woman whose the son is killed as a jaywalker by a hit - but not run - driver, a man whose the wife is about to give birth to their first child. Nine years later the deceased's mother - Nathalie Baye - seeks for a terrific revenge for her son death. She impersonates the killer husbands'secretary, assistant, and then step by step plans an insidious and machavellian intrusion inside the man's life, professional and personal: wife, child, father. Nathalie Baye is here absolutely outstanding as the villain, the first time in her career. But a villain character for whom we feel great empathy. This film reminded me another french feature which was made back in 2008: L'EMPREINTE DE L'ANGE, nearly the same atmosphere and same kind of story, if not the same tale. Don't miss it.
