Monogram's Johnny Mack Brown western series galloped ever onward in Hidden Danger. This time, Johnny and his saddle pal Banty (Raymond Hatton) come in contact with a cattlemen's protective organization. Ostensibly an honest venture, the association is the front for an extortion racket, headed by a gent named Carson (Myron Healey). The action highlights are complemented by the comic antics of Max Terhune and his dummy Elmer. Aging star Brown relinquishes the romantic responsibilities to Marshall Reed, who spends his screen time wooing heroine Christine Larson. ~ Hal Erickson, Rovi
