Roadkill (2008)

Four friends on their way home from a fun filled weekend at a lake find themselves living their worst nightmare when they take a shortcut off the main highway. After running over a body in the road and finding their car no longer operational, they stumble upon the home of a family whose intentions are anything but good. It will be a fight for survival between four innocent young adults and a family of inbred backwoods cannibals to see who will live to see the morning.
