After inheriting a ranch full of mysteriously vanishing cows, Ernest "Dude" Selby (George O'Brien) suspects the culprit may be wheelchair-bound ranch boss Sam Hepburn (Henry Hall), father of the beautiful Ann (Irene Hervey). Going undercover to investigate, Selby learns more than he bargained for. Costarring Syd Saylor as a trusty cowhand and LeRoy Mason as a secretive foreman, this rousing Western is based on a story by Zane Grey.
