The Christmas Season Massacre

On Christmas Eve, sometime after a woman is disemboweled in the woods of Christmastown, California by a man dressed as a pirate, a couple drive to a field, which the man, Boom Boom, claims is where Tommy "Oneshoe" McGroo buries his victims, the people who used to bully him. Boom Boom tells his girlfriend, Kitty, that Tommy acquired his nickname when one of his shoes was stolen, and he could not afford another due to his family's poverty. Tommy asked for replacement footwear for Christmas, but instead got an eyepatch with a Christmas tree on it, since he idolized pirates. Driven insane by this, Tommy began murdering his tormentors, though most consider him an urban legend. After telling Tommy's story, Boom Boom goes to urinate, and has his testicles ripped off by Tommy, who then wounds Kitty. Later, Tommy snaps the neck of man having kinky sex with his blindfolded wife, who Tommy then rapes.
At Lame Dog Hollow Camp, Tommy's remaining former classmates are assembled by Ernie Cunningham, who wants them to team-up to kill Tommy when he inevitably comes looking for them. Until then, the group members spend their time trying to amuse themselves, with amateur guitarist Isaac Hiltzik (who only talk sings) and his girlfriend, Lana Hooper, heading to the nearby lake, where Tommy knifes them. The next to die is awkward nerd Dorcas Cunningham, who Tommy sneaks up on with a running chainsaw, only being noticed when he steps on a twig.
After the sultry Abby Honeydew is stabbed while looking for their missing friends, Ernie and Danny make plans to try and summon Tommy's previous victims with a Ouija board, but Ernie is killed with a screwdriver while traversing a cemetery. Danny fights Tommy, and stabs him in the head with a rail spike, though Tommy recovers from this, blasts Danny with a shotgun, and takes one of his shoes. Five years later, Tommy (who still has the spike protruding from his head) is shown to have married the woman he had sex with, and the two have a son, who Tommy gives his eyepatch to as a Christmas present.
