Mystery Ranch

To maintain his vast ranch holdings, Henry Steele holds Jane, the daughter of his deceased business partner, against her will. Stalwart ranger Bob Sanborn rescues Jane in a riding incident and is invited to stay over at the ranch by the malevolent Steele, who catches on immediately to the fact that Sanborn has been asked by Jane to help her escape. Steele escorts Bob off the ranch just after giving the order to his vicious ranch hands, Mudo and Tonto, not to let him leave alive.
