Friday the 13th Part 2

Order up the quarts of fake blood, because box-office dollars equal more dead bodies.

It's five years later (one in real life) and another batch of fools wants to open a camp near the infamous murder site, Camp Crystal Lake. Before the kids can arrive, someone shows up and starts disecting the counselors in the dead of night. While a bunch go into town, the ones who stay behind to hit on each other---or score---end up smeared. Two are speared while in post-coital bliss; a girl who finds their bodies is knifed; and in a nod to being non-discriminatory, a guy in a wheelchair has a machete plunged into his face. One of the more lasting images from the series is the victim careening down a stairway in the rain still seated in his wheelchair.

The cute heroine and her friend return to camp to find a darkened cabin and bloody sheets. Attempting to leave, he's knocked out and she's chased for the next twenty minutes. It's pretty tense, with pitchforks through VW Bug rooves, chases into the woods, it all ending up back at the original camp from part 1.

The girl finding herself in a shack full of her dead friends, not to mention the killer's mother's disembodied head. The psycho is revealed as Jason, the son of the killer from the first film. He's apparently the one who avenged his mother's death in the opening of the film, dispatching the survivor of part 1.

...He then heads off to the new camp and starts his aforementioned fun.
