Two brothers are plunged into the realm of psychic horror, one tormented by a stalker, and the other involved with a girl whose home is the site of eerie occurrences. Asaji is in love with Ryoji. Ryoji senses her presence wherever he goes, but he figures it's just a crush and that it won't go much further, but he couldn't be more wrong as Asaji begins stalking Mariko, Ryoji's girlfriend. When a female friend of Ryoji is killed in an accident while talking with him on the phone, her last word is, "Asaji..." But, she couldn't be involved, she was with Ryoji at the moment of her death... As soon as Naoko moves into Room 505 of her new apartment, she hears stories about strange accidents and eerie phenomena surrounding apartments with the number "5." She runs into Kazuhiko, Ryoji's brother, whom she saw taking photos of her condo. He won't say what he was doing, but he warns her to be careful. Accidents continue to happen in condos with the number 5 and something in Naoko's closet is taking on a gruesome form.
