Tom Atkins, who also starred in John Carpenter's The Fog, uncovers a new kind of Halloween horror in the successful series from producers-composer Carpenter. Dr Daniel (Challis (Atkins) and Ellie Grimbridge (Stacey Nealkin) stumble onto a series of gruesome murders when her father, who sells Halloween novelties, is killed by an emotionless android assassin. An Oscar nominee for The Adventures of Robinson Crusoe, Dan O-Herlihy is Conal Cochran, a demented toymaker who wants to return the holiday to its dark roots using his Silver Shamrock masks. His unspeakable scheme will unleash death and destruction across the country, unless Challis can stop him in time, in this nightmarish thriller from Tommy Lee Wallace, the director of Stephen King's It.
