As in previous Sleepaway Camp movies, Pamela Springsteen (yes, Bruce's sister) plays Angela, a serial killer bent on bumping off camp counselors. In a sense, Angela is a female Jason Voorhees, and yet she's not: Jason is a superhuman freak of a killing machine, while Angela is a fairly normal looking girl who terminates her colleagues because they annoy her. So it goes with Jan Hernandez, whom Angela discovers having sex in a tent. Are people having sex in a tent annoying? Apparently so.
