A violent slaughter occurs in an abandoned house in Louisiana where six youngsters are found dead. Detective Mark Louis (Frank Grillo) examines the crime scene and finds a shocked survivor, John (Dustin Milligan) before calling reinforcements. Several police cars then arrive the house alongside with an ambulance and a psychologist, Dr. Elizabeth Klein (Maria Bello). She talks to John, who tells that a séance performed in the house called the attention of many spirits, including one he identified as his mother. The following scenes consist of two interlaced plots: one shows the interrogatory of John by Dr. Elizabeth and the investigation of videotapes found in the house by police officers and the other shows the actual events (often filmed by a camera) that John and the five other visitors of the house experienced, including several paranormal phenomena.
