Jonathan Rivers (Michael Keaton) is a successful architect and lives a peaceful life with his wife Anna (Chandra West) until her unexpected disappearance. Eventually, he is contacted by Raymond Price (Ian McNeice), who claims that his own son had also died. He says he has recorded messages from Anna through electronic voice phenomena (EVP). While Jonathan is initially dismissive and angered, he later learns about his wife's tragic drowning. Desperate, he begins to believe that the recorded voice is indeed that of his wife. Jonathan becomes obsessed with trying to contact her himself, despite warnings from a psychic, Mirabelle Keegan (Keegan Connor Tracy), who tries to tell him how the recording can attract other, unwanted entities. A woman named Sarah Tate (Deborah Kara Unger), who also came to Raymond for his EVP work because she lost her fiancÃ©, befriends Jonathan.Raymond is found dead. Jonathan begins to be followed by three demons attracted by his obsession with EVP, and finds that some of the messages he is coming across are from people who are not yet dead, but may soon be. Jonathan hears cries from a woman whom he finds in a car with a child. He is able to save the child, but not the woman. At that woman's funeral, which Jonathan and Sarah both attend, Jonathan approaches the husband and tells him about what happened. The latter thanks Jonathan for saving his son but then asks to be left alone. The husband continues to tell Jonathan to stay away from him and his family. Afterwards, Jonathan sees images of another person, a missing woman named Mary Freeman, while working with his EVP devices. Sarah is later seriously injured by a fall from a balcony while possessed by the demons, that incident which was foreshadowed by Sarah's image being among those on the EVP devices.Jonathan locates the site of his wife's death by following signs on recordings and he also finds his wife's abandoned car. Jonathan finds a set of computers and electronic equipment on site. A construction worker (Mitchell Kosterman) from his company, who has been doing his own EVP work, is holding Mary captive. He has been under the control of the demons to kill all these people, including Anna. The three demons torture Jonathan by breaking his arms and legs and cause him to fall to his death, but a SWAT team along with Detective Smits (Mike Dopud) arrives and are able to save Mary by shooting the construction worker dead. After his funeral, Jonathan's voice can be heard on the radio through static interference saying "I'm sorry" to his son. The child recognizes the voice and smiles. Sarah, at the graveside in a wheelchair, is menaced by odd noises. And right before the credits roll in, the camera flashes to a TV where Jonathan and his wife are visible.
