Tripper is the head counselor at a budget summer camp called Camp Northstar. In truth, he’s young at heart and only marginally more mature than the campers themselves. Tripper befriends Rudy, a loner camper who has trouble fitting in. As Tripper inspires his young charges to defeat rival Camp Mohawk in the annual Olympiad competition, Rudy plays matchmaker between Tripper and Roxanne, a female counselor at Northstar.

When six friends fly off on a weekend getaway and are suddenly plagued by engine trouble, they’re forced to land on a remote island. Looking for shelter, they’re grateful to encounter Ma and Pa and their children – an eccentric family living in the island’s backwoods. But what begins as simple hospitality turns into a terrifying race for survival as the friends start disappearing one by one … and turning up dead.
