Wyatt, a professional thief living off the grid, is recruited by his brother for one last job. Their target: an armored car traveling down a desolate stretch of California highway. But when it turns out that their target is carrying not gold bars but human cargo, Wyatt is plunged into a conflict between warring factions of a doomsday cult. The cult claims that it is their solemn duty to save the world by means of human sacrifice. Will Wyatt protect the boy who has come into his charge? Or will he be swayed by the cult's increasingly convincing claims that the end of the world is fast approaching?
