Traumatic childhood memories Logic be damned, "Horror High" has a story to tell, and it's going to get there by any means necessary. It takes place in a high school where the resident outcast, Vernon, is a science geek who would probably even be picked on by Carrie White. His mother's dead, his father's completely absent, and every single person Vernon comes into contact with abuses him verbally and often physically. His teachers berate him, even though he is clearly gifted. The school janitor is a shambling, mumbling alcoholic constantly on the verge of a violent outburst--you know, just like in real life--and not only does he seem to actually LIVE in the high school, he keeps a pet cat in the school, too--you know, just like in that same real life.
Vernon's determined to prove that people can be changed physically by drugs. No, really! Who ever thought that could happen? Anyway, he injects his guinea pig, Mr. Mumps, with a formula that causes it to turn into a feral monster with much darker fur than normal. It kills the janitor's bully of a cat, and the janitor freaks on Vernon, forcing him to drink the Jekyll/Hyde potion. Yeah. So suddenly Vernon convulses and transforms into killer-Vernon, hurling the janitor around and finally dunking his face in a giant barrel of sulfuric acid that just happens to be sitting in the lab as a means of disposal. And that's just the beginning.
Rosie Holotik from "Don't Look In the Basement!" plays a classmate of Vernon's, the only person in the whole school that likes him. She's there to be alternately romanced and threatened by killer-Vernon. Austin Stoker, he of "Abby" and "Assault on Precinct 13", is a detective investigating the sudden "rash of killings" at Vernon's high school. I mean think about that for a second...a janitor is killed, then a teacher, and yet the school dismisses it as a "rash of killings" and remains open and functioning? This is the charm of "Horror High"; it is an outrageous adolescent fantasy, where a nerd is picked on and suddenly becomes a monster that can not only take revenge on his bullies, but KILL them. When reality attempts to disrupt the fantasy, it is immediately brushed aside and never given a second thought. WHY does the school stay open after a janitor's skull is found floating in a barrel of acid? For that matter, why is a giant barrel of acid sitting in a classroom? Why does the janitor not only seem to live on the premises of the school, but keeps a pet cat there? Why would a teacher threatened in her classroom run from her desk, be chased through the hallways, then return to her classroom, and her desk, trailing her fingers along the edge of a paper cutter as if tempting fate? The answer to all of these questions and more is: "It was in the script." Vicious cruelty to animals, a melted human face, football bullies, and mean teachers. These are the things that would give any young school kid nightmares, after which "Horror High" has accomplished what it clearly set out to do.
** for even more fun, take into consideration an unrelated passage of the film that was awkwardly inserted into the television version entitled "Twisted Brain". The narrative suddenly shifts from Vernon's world to demonstrate the romantic relationship between his father and the woman he's currently living with as a traveling salesman. Then, when sufficient padding has been accomplished, the film goes back to Vernon's plight, never to mention the father or his girlfriend again.
