Meet Santa and Mrs. Claus: he's a one-eyed lunatic, she's a curvy, bat-swinging blonde. This serial-killer couple is splattering the holidays in a small town in upstate New York, staging one bloody rampage per night. Though the victims seem random, a mall Santa, a smooching couple, a quiet family, high-schooler Jennifer and clever cop Sam begin to unravel the sinister pattern behind the slayings. Can they stop the murders before Christmas comes and there's no one left to celebrate?
