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.
