Our Hero is accused of a crime he didn't commit. Once again, he breaks jail to find the real culprits. And once again, he dons his Durango Kid disguise, whereupon stunt-double Jock Mahoney swings into action. Outcasts of Black Mesa is distinguished by the presence of a relative newcomer to the film game, leading lady Martha Hyer.
