Scott, his girlfriend Valerie and their friend Trey, all in their 20s, take a trip to a sweat lodge spiritual retreat at the suggestion of another friend, Daniel. The lodge, run by a half-baked spiritual guru, happens to be situated upon a portal separating our reality from another dimensional plane. During the sweat lodge ceremony, the four friends black out and are pulled into the alternate dimension. They awaken to find four ancient, evil inhabitants of this astral purgatory determined to steal the friends' bodies to cross back over into our world. Armed with only their wits and will power, the friends must fight the evil spirits in an epic battle where the losers will be stranded forever in the empty and barren wasteland.
