One night in 1977, a live television broadcast goes horribly wrong – unleashing evil into living rooms across the United States.
Jack Delroy (David Dastmalchian; Dune, The Dark Knight) is the host of a late-night talk show. On his Halloween night slot, 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.
