Sleepaway Camp's Best Scenes by The B Movie Cutup

From the Wikipedia Article:
"The main character, Angela Baker (Felissa Rose), and her cousin Ricky (Jonathan Tiersten), are sent to summer camp one summer. Angela had come to live with Ricky and her Aunt Martha eight years earlier, after her father and her brother Peter were killed in a boating accident. Angela, a painfully shy 14-year-old, is bullied severely by most of the other campgoers and counselors at Camp Arawak. Her main foil is Judy (Karen Fields), a vain girl once friendly with Ricky but now snubbing him in favor of the older boys.

Soon people are being killed in bizarre ways, such as a youth being stung to death by bees from a hive thrown into a bathroom. In a nod to Psycho, a female counselor is stabbed in a shower stall. The murderer turns out to be Angela; however, it is later revealed that Angela was actually her brother Peter. The real Angela had died in the boating accident eight years ago, and Peter assumed her identity afterward. This was because Aunt Martha wanted a girl and chose to raise Peter as a girl, treating him as if he was Angela. Angela-Peter is last seen standing on the beach naked with the decapitated head of another camper at his/her feet.

In the commentary on the DVD, Hiltzik and Rose tease that perhaps Angela isn't the sole killer in the movie. In fact, the only real continuity error in the film involves the killing of campers at a tent site far enough away from the main camp that they took a car to get there in the same night that four other people were murdered."
