I only half-watched this, it was pretty bad. A group of four high school girls who've been raped by men team up to kill men, including the movie's narrator. Throughout the movie, a gong appears and is gonged whenever there is going to be a violent scene: the "gore gong." There is also a "hooter honker," which is a pair of bulb-type bicycle horns. This is really stupid, and about the level of humor in the movie.
As in Gorman Bechard's other movies, this is set in Waterbury, Connecticut, has Carmine Capobianco in it, has characters talking to the camera, and has at least one scene set in a video store. I don't know if his more recent movies have these features; I'm hoping he's gotten better.
The title "Cemetery High" and the video box cover of women in scanty clothing in a graveyard, one holding a bloody chainsaw, is misleading. I don't recall a scene in a graveyard. I guess it refers more to the fact that high schoolers are killing lots of people.
A bumbling mayor, policeman, and coroner try to figure out who the "scumbusters" are, although two of them destroy some evidence. Maybe if I was paying more attention I would have known why, if it was incompetence, or if they were covering for the women for some reason.
Mainly, it's just boring with lame humor.
