Steven and Diane Freeling live a quiet life in an Orange County, California, planned community called Cuesta Verde, where Steven is a successful real estate developer and Diane looks after their children Dana, Robbie, and Carol Anne. Carol Anne awakens one night and begins conversing with the family's television set, which is displaying static following a sign-off. The following night, while the Freelings sleep, Carol Anne fixates on the television set as it transmits static again.
