After a boy is scared by his slightly disturbed grandfather, he witnesses his father shot point blank by a hitch hiker and, after a failed attempt to rape his mother, he slashing and death.
Years later, in an orphanage, the little boy (Billy, now a teenage with a build rivaling Jason Voorhees) is forced to play Santa in the local general store. Chaos and bloodshed ensue.
A week after absorbing this, and then watching it again, the primary reason anyone would watch this would be the gore and the nudity, on which it delivers. With a good body count (12) and lots of unnecessary nudity, this pretty much delivers what you would expect from a B-Grade slasher.
Unfortunately, if you would expect weak acting and unexplained plot holes in an 80's B-Grade horror movie, you would get exactly what you expect. There is no explanation as to the grandfather's crazy thoughts on Santa, nor is it explained as to why (spoiler) a girl would go ape-shit monkey-fuck ballistic on Billy after an attempted rape was stopped (albeit, Billy did kill him). But these things aside, if you're looking for a good, non-thinking, "kick back with popcorn and tally up the blood splatters and nude scenes" show, this would definitely be for you! And let's face it, not everyone wants cerebral films 24/7. Sometimes, you just want some amusement, which this film provides.
On the topic of nudity, there is plenty, including one of Linnea Quigley in one of her earlier film appearances, and many other ladies who went on to great things, such as... well, not really.
Gore? A bullet to the head, a slit throat, hanging by a string of breaking Christmas lights, an impalement on a deer head (!!!), glass punctures from being thrown out a window, a decapitation and several more gunshots and other forms of death later, we have an ending. I won't ruin it for you.
I do believe this film does try to touch on deeper topics (human sexuality and what is viewed as "right" and "wrong"), but it gets lost in translation: by the time the viewer absorbs it (if the viewer absorbs it), there's another naked woman, distracting all the males who could have turned this into a thinker's film. Such is life: it serves better as a good splatter flick than a deep film.
