When six young friends fly off on a weekend getaway and suddenly find themselves with engine trouble, they have no choice but to land on a remote Pacific island. Looking for shelter, they are grateful when they meet Ma and Pa and their children: an eccentric family still living in the backwoods as if it's still the 1920s. But what begins as simple old-school hospitality becomes a terrifying race for survival when one by one, the friends start disappearing and dying horrible deaths. Fleeing the outside world many years ago, the family has created an island domain, where all strangers are sinners: and the killing has never stopped.
