The synopsis: Quiet Angela (Felissa Rose) is sent to sleepaway camp in an effort to make her come out of her shell after the accidental death of her brother, Peter, earlier in the year. She soon finds herself running for her life as a string of murdered campers pop up.
The twist: The insane ending of this slasher just saves it from being totally cheesy, since everyone discovers that Angela is not only the killer, but she's a he! Angela is the one who died in an accident prior to the film, and Peter took over her identity with the help of their aunt, who dressed him in girl's clothes. Angela/Peter's fellow campers discover this when they come across him naked (like, really naked, if you know what I mean), holding the severed head of his last victim.
