Deep in California's Gold Country, there is a rumor of a cabin on a lake. The old cabin was used by miners during the Gold Rush, but the maps all agree that the cabin simply isn't there. Three boys who are away at camp for the summer have made a grim discovery. Not only is the cabin actually there, but it is crawling with their deepest fears. Ghosts, clowns, and crawling skeletons drive the boys to take desperate measures to survive. The evil lurking in Angel Camp could make the campers ghosts, themselves.
