Movie cowboy Jeffrey Carson (George O'Brien) tries hard to live up to his image in this "backstage western." On location in Wyoming for a picture, Carson -- travelling incognito -- finds himself in the middle of a real-life range war, stirred up by eastern racketeers. When the advice of his screenwriter "Great" Gadsby Holmes (Joe Caits) fails him, our hero tackles the villains on his own, performing far more gallantly than ever he did on screen. As a reward, Carson wins the hand of pretty ranch owner Joyce Butler (Cecilia Parker), with the begrudging blessing of Joyce's Aunt Violet (Maude Eburne). Hollywood Cowboy was produced independently by George A. Hirliman, the same man previously responsible for O'Brien's more serious actioner Daniel Boone.
