The Carters are an idyllic American family traveling through the great American southwest. But their trip takes a detour into an area closed off from the public, but more importantly from society. An area originally used by the U.S. Government for nuclear testing that was intended to remain empty. When the Carter's car breaks down at the old site, they find themselves stranded. As the Carters may soon realize that what seemed like a car casually breaking down, might actually be a trap. This trap might be perpetrated by the inhabitants of the site who aren't pulling a prank, but are out to set up a gruesome massacre.
