When a desolate highway is inextricably closed, five students sharing a ride to a party in the desert find themselves trapped in a deserted travel oasis. The students are determined to have a good time but their fun is interrupted with horrifying visions of mutilated travelers. They discover that the oasis is something of a conduit between the living and the dead. Led by a blind grad student with heightened senses, they must survive the night and confront what appears to be a terrifying abyss between the living and the dead.
