Slaughter High

Slaughter High is a 1986 AmericanBritish independent slasher horror film written and directed by George Dugdale, Mark Ezra and Peter Litten.

The students are forced to perform a vigorous workout in the gymnasium. Still, two students give Marty a marijuana joint laced with poison, which he smokes in the science lab where he is working on a chemistry project. The joint makes him so sick he runs to the mens room to vomit. While he is gone, Skip, one of the popular kids, rigs the experiment to explode in Martys face.Upon Martys return, the setup works, causing Marty to panic, and a great fire to erupt in the lab after he knocks over a Bunsen burner. In the struggle, Marty accidentally bumps into a shelf where a precariously placed jug of acid sits, causing the jug to fall and break, which splashes acid on Martys face, leaving him horribly disfigured. The sound attracts the attention of the students, who stand by the door in shock. As Marty is taken away on a stretcher into an ambulance, Carol approaches Marty on the stretcher to apologize, but Marty grabs her by the neck. She screams and wakes up in bed. ........
