The Dawsons have decided to take an impromptu camping trip since their parents are out of town. When the park closes at 8:00 p.m. and the sun sets, ancient residents make themselves known, and the three children are thrust into a supernatural world where their eternal freedom is at stake.

On a late September afternoon, three teens embark on a weekend of relaxation only to find themselves engaged in a supernatural struggle against an evil that seeks to take them captive for eternity.
