An archeological expedition releases an ancient evil. That ancient evil is Santa Claus.
The movie is a silly horror spoof, but it is set in a world that is in no way silly. Our hero, a little boy who believes in Santa Claus (and who knows that Santa Claus is a demon) carries a shotgun and knows how to use it. They boy’s father, a widower, has set up a wolf trap in front of the slaughterhouse he works in. They are strong and hard people. There is a western buried underneath this movie, or perhaps put on hold because of the events of the movie.
