The Dude Ranger plot
"GEORGE O'BRIEN RIDES AGAIN!...A lone galloping terror...who daunts a band of desperate criminals...and sweeps a girl into his arms...as he fights to save her from a murderous plot!"
Ernest "Dude" Selby is a man from the east who inherits a ranch. Once there, he notices that most of the livestock has been stolen. The ranch is run by Sam Hepburn, a man confined to a wheelchair. Hepburn thinks Selby is a cowboy who has stuck around because of Ann, Hepburn's beautiful daughter. Hepburn hires Selby as a cowboy, unaware that Selby owns the ranch. Selby accepts the offer to better investigate the theft of cattle. Selby soon finds out that nothing is what it seems at first glance at the ranch. With the help of the cowboy Nebraska Kemp, he soon learns that Sam Hepburn is not as handicapped as he makes out.
