It turns out that Santa Claus is not really the cuddly, harmless old fellow that we all know and love. In fact, he's a devil, and the only thing that has been keeping his bad side in check all this time is a bet he lost with an angel. Now, the bet has expired, and 1,000 years of good cheer will be replaced by Christmas fear. This Christmas will be a violent night of chaos, with Santa bashing his way through town. Local boy Nicholas, his girlfriend Mac and his crazy Grandfather are the only ones who know the truth about Santa and can save their town and the world.
