A young nursing student, Asuka Ninomiya moves to a dilapidated apartment complex with her father, Isao; mother, Sachiko ; and younger brother, Satoshi. She tries to greet her elderly next door neighbor, Shinozaki, but with little success, and befriends a local boy named Minoru Kinoshita, whose only guardian is Shinozaki. Asuka begins to experience strange things, including scratching noises and the sound of a loud alarm clock, both of which come from Shinozaki's flat. She is also wary of her own family, who seem to be doing the same activity and repeating the same conversation everyday. Asuka later discovers that Shinozaki had died while scratching the wall, explaining the noises she heard every night. A detective tells her that he had been dead for three days without anyone finding him. Since then, Asuka feels that Shinozaki haunts her in anger for not finding him earlier. When a cleanup team arrives to clean Shinozaki's flat, Asuka becomes acquainted with Shinobu Sasahara, a cleaner with experiences in the supernatural who tells her that the living and the dead reside in two separate times: the living move forward in time, while the dead stop at the time they died. Asuka consults with Sasahara about Shinozaki's haunting and is told that he can contact a psychic friend of his. Returning home, Asuka is greeted by a completely empty home and no family and becomes hysterical. Sasahara learns from Asuka's foster parents that Asuka's entire family had died from a bus accident years ago with Asuka as the only survivor; since then, Asuka has been blaming herself, refusing to move on. Sasahara invites his psychic friend, Sanae Nonomura, who concludes that Asuka is not haunted by Shinozaki - he only wanted to say thank you for discovering him and warn her that she is in danger. She is actually being haunted by Minoru, a boy from the apartment complex who died 13 years ago when he hid inside a trash bin during a hide-and-seek game and was incinerated. Asuka becomes withdrawn and depressed, refusing to move out even when Sasahara begs her to. She continues to play with Minoru, seeing him as a replacement for her dead little brother. Sasahara and Nonomura force her to allow the latter conduct an exorcism to expel Minoru's spirit from inhabiting Asuka's damaged mind. Sasahara forces Asuka not to let Minoru enter the flat even when Minoru projects her family's last memories, but he himself is lured into Minoru's trap when Minoru projects his vegetative girlfriend, Hitomi Makimura, who is in a coma. He lets Minoru in, killing Nonomura in the process. Asuka agrees to become Minoru's playmate in exchange for Sasahara's life, but Sasahara pushes her away, and gets himself thrown into a memory of Minoru's trash bin, where he is burned alive. Asuka, found scratching and screaming at her apartment floor, is taken back by her foster parents. Despite their insistence, she continues to babble about her dead parents and brother while clutching her brother's doll.
