A retiree hopes a week with her grandchild will provide an opportunity to repair her tense relationship with her daughter, but an accident soon undercuts whatever trust remains. With the help of her best friend, whose son has recently been released from prison, she plots a path towards restoring the family life so long denied her. With a deceptively placid surface, master stylist François Ozon cooks up a twisting and destabilizing thriller where family ties remain the most mysterious ingredient of all.
