Orphaned at a young age, twenty-one-year-old Justine lives with her cousin and grandparents in France, where she's a nursing assistant in a retirement home. It's there that she meets Hélène, a nonagenarian resident who shares her life memories and helps Justine confront the tragedy of her past. While investigating a series of anonymous calls to the family members of the residents who remain "forgotten on Sunday," visiting day at the center, Justine comes across startling information about her parents' death. A beautifully told, sometimes racy, rumination on love and the shadow of the past.
