A big, camouflage wearing psycho killer is going around offing the girls in a high school cheerleading squad. It's up to the local Sheriff (Mark V. Jevicky) and a big shot detective (Carl Hetrick) to weed through the possible suspects. One recurring clue: this killer seems to have a thing for the purifying qualities of water.
At first glance, this would seem to be a VERY typical slasher, albeit one directed by the legendary Cemetery Zombie of "Night of the Living Dead", S. William Hinzman, and scripted by John A. Russo, based on his novel. There's zero suspense and zero scares, but Hinzman goes through the motions adequately, serving up lots of nudity and violence. Some of the actors are reasonably amiable, but the performances are, by and large, amateurish and dull. (Russ Streiner, a.k.a. Johnny in NotLD, appears here as a pontificating priest.) The trying-to-ape- John-Carpenter electronic score is good for some chuckles, to be sure.
Where this actually gets interesting is at the two thirds mark. Here, the killer gets revealed, and even if you've guessed their identity correctly, it's a hoot that the way that the plot thickens. Then the killer, due to their compromising position, is obliged to help a character from a subplot take care of their problem. (Reminding this viewer of the 1975 Giallo "The Killer Must Kill Again".) Things go bad for almost everybody, and eventually the story turns into a tried-and- true revenge saga! This finale comes complete with some nifty explosions and bloody squib action.
The final third of the picture may be a turn-off for some die hard slasher fans, but just speaking personally, it's what helped to make "The Majorettes" more than just run-of-the-mill for this viewer.
