But when her mother falls ill, Pim is forced to return to her hometown in Thailand, where she is haunted by vivid flashbacks of her painful memories. As the ghost of her twin sister Ploy, who died in a tragic accident, begins to torment her, Pim's grasp on reality starts to slip. With Wee struggling to understand her increasingly erratic behavior, Pim must confront her dark past and the truth about her sister's death in order to find peace and closure.
