In 1977 a live television broadcast goes horribly wrong, unleashing evil into living rooms across the United States. The film stars David Dastmalchian (Dune, The Dark Knight) as Jack Delroy, host of a late-night talk show. On Halloween night 1977 havoc unfolds when Delroy interviews a parapsychologist and the subject of her recent book, a young teenager who is the sole survivor of a Satanic church's mass suicide.
