In Thailand, young Ton Chatree (Trairat) is sent to a boarding school by his father to get good grades and does not tell his mother about his father having an affair. Once in the school, Ton feels like an outcast and misses his family and friends. His new schoolmates tell ghost stories about a boy who died in the school swimming pool and a young pregnant woman who committed suicide. The stories frighten him, thereby exacerbating Ton's difficulties adjusting to the school. However, Ton becomes close friends with another lonely boy, Vichien (Chienthaworn), who Ton later discovers is the boy who drowned, and his death repeats every night. Ton finds a way to help his friend rest in peace.
