Katie (Katie Featherston) and her boyfriend, Micah (Micah Sloat), are a young couple who recently moved into a two-story tract house in suburban San Diego, California. Katie claims that a ghostly presence has haunted her since her youth and believes that it has followed her to their new home. She hires a psychic, Dr. Fredrichs (Mark Fredrichs), who assesses that she is being haunted not by a ghost, but by a demon. He says the demon feeds off negative energy, and its intent is to haunt and torment Katie no matter where she goes. Before leaving, he advises them not to taunt or communicate with the demon, and to contact demonologist Dr. Johan Averies for help. Instead, each night, Micah mounts a video camera on a tripod in their bedroom to record any paranormal activity that might occur while they sleep in the hopes of solving the problem himself.
