1973: A group of National Guardsmen are on a training exercise deep in Louisiana's Cajun country. When they make the mistake of offending the local swamp dwellers by stealing some Cajun pirogues they trigger a bloody shoot out. Only two them, Spencer and Hardin, manage to escape into the foliage, stumbling upon a Cajun ceremony. Believing they are among friendly people, the troopers soon learn otherwise. Their frantic attempt to escape takes them ever farther into territory that their predators know much better than they.
