Suddenly, Doctor Daniel Challis (Tom Atkins, The Fog, Night of the Creeps) finds himself thrust into a terrifying Halloween nightmare. Working with the salesman's daughter, Ellie, Daniel traces the mask to the Silver Shamrock Novelties company and its founder, Conal Cochran (Dan O'Herlihy, RoboCop).
