It's summer camp as usual at Camp Manabe where the kids torment each other for fun while the underpaid camp staff provides as little supervision as possible. Greedy camp owner Frank and junior partner Ronnie do their best to keep everyone in line, but something sinister is about to put a slash in the roster. When campers and staff mysteriously begin disappearing and turning into gruesome corpses, paranoid Ronnie can't shake the memory of a series of grisly murders that took place at Camp Arawak, where he worked two decades earlier. Has a ghost from the past come back to haunt him? As the paranoia worsens, Ronnie's list of possible killers starts growing just like the body count. Everyone becomes a suspect from vicious kids to shady members of the camp staff, and even former Camp Arawak camper Ricky who mysteriously works nearby. Who is knocking off these victims and why? Only one thing is for certain, something is carving a bloody new trail at Sleepaway Camp where kids can be so mean and surviving this summer is gonna be a real killer!
