On their way to a sailing trip, an aging husband and wife invite along an emphatic young hitchhiker out of sheer patronization.

Six strangers suddenly awaken in a remote, endless cornfield. Stripped of their possessions, they are left with only six items: a gun with a single bullet, matches, a lantern, a knife, a compass, and a flask of water. As mysterious sirens blare in the distance and traps appear at every turn, the group realizes it’s been plunged into a cat-and-mouse game with an unseen evil, and survival depends upon solving a diabolical and deadly puzzle.

John, Julian and Paul enter the Kaibab National Forest for a three-week survival trip and peyote vision quest. The only items they take with them are a knife, a bottle of water and a garbage bag each. A week into their journey a disastrous turn of events changes everything and the men are forced to ultimately confront the darkest corners of their morality and mortality. Battling the elements and each other, the quest becomes to make it out of the forest alive.
