Chi, a rebellious 18 year old girl, returns to her home town on the day her rich stepfather, Huy, makes a generous donation to a village temple. At the celebration, her sister, Ai, drowns in a nearby river. When Ai's uncle Thuc, who is a policeman, travels to a village morgue to identify Ai's dead body, the girl sits up, very much alive. Thuc brings Ai home to her family, but he doesn't tell them about her death. Everything seems to be happy until Ai shows signs of spiritual possession. A shaman is brought in to perform an exorcism, but she is unsuccessful, claiming, "Your daughter is not possessed by a dead spirit, but by a lost soul of a living person". To investigate the source of her sister's possession, Chi journeys to the village where Ai was found. What she discovers is a community victimized by human trafficking and child prostitution. There is another little girl, whose tragedy is tied to Ai's death by a secret, and a vengeful spirit that follows Chi home, and destroys her entire family, as dark secrets unravel and evil unleashes its true visage.
