A group of young travelers discover that sometimes man is the greatest monster of all after getting lost in the desert on their way to the Burning Man festival and coming face to face with an unstoppable creature. It was supposed to be a wild weekend of casual sex and drug-fueled revelry. That is, until five students stopped into a remote gas station in search of directions. When the owner of the gas station inexplicably accuses the teens of stealing his dog, a Park Ranger kindly steps in to clear up the confusion. Back on the road later that night, the driver opts to try and make up for lost time by taking a shortcut. By the time the rest of the group realizes what's happened, they're all hopelessly lost. But someone is out there, and when the group spots a dilapidated shack in the distance, they decide to check it out. Unfortunately for the weary students, the sole occupant of the shanty is a violent hermit who doesn't take kindly to strangers. A struggle ensues, leaving the mystery man mortally wounded and the travelers with little choice but to pitch a tent for the night. As the man lies dying, he uses his last breath to utter a cryptic warning: "You are so screwed." And screwed they are, because somewhere too close by for comfort dwells a creature that exudes an oddly intoxicating smell, and possesses the power to devour humans whole. But who is the real monster, the creature that simply acts according to its nature or the man willing to sacrifice all of his closest friends in a selfish bid to cheat death?
