15. Sleepaway Camp (1983)
Director: Robert Hiltzik
Stars: Mike Kellin, Katherine Kamhi, Paul DeAngelo, Jonathan Tiersten, Felissa Rose, Karen Fields, Christopher Collet
Vacation destination: Camp Arawak
Like Jason Voorhees and his mom did at Camp Crystal Lake, young and scrappy Angela (Rose) was letting the bodies hit the floor at Camp Arawak. Proving that picking on your fellow campers is never the way to go, Angela enacts macabre methods of revenge upon her every tormentor for instigatory acts both big (a pedophile cook who tries to cop a feel) and small (water balloons tossed in her direction).
It's no wonder this cult slasher classic was dubbed The Nightmare Vacation. But like the worst best nightmares, not everything at Camp Arawak is what it seems, and this twisted tale concludes with one of the most unexpected revelations in horror history.
