As described in a review in a film magazine,[1] settler Old Man Hayes (Swickard) resists the attempt of the water company to secure his property and is killed. Years later, a mysterious champion known as Whitehorse Champion arises and helps the settlers in their fight to keep their cattle from dying of thirst. He is called that because of the color of his mount and because he leaves a bit of cactus as a sign of his visit. Lawyer John Henderton (Russell) is the representative of the water interests and his daughter Belle (Holmes), while riding through the woods, sees her horse run off to be with its mate, the horse of Whitehouse Cactus (Hoxie), who is really Hayes' son Jack (Hoxie). He discovers by a scar on the hand of Belle that she was the little girl playmate of his many years ago when he was a child, and they become fast friends. Later, Belle discovers that Jack is the mysterious champion, and, when her father is shot, she goes to arrest Jack herself. He convinces her of his innocence. When the sheriff arrives, she notes that Belle is the only one who can prove that Jack is the Whitehorse Cactus, but that a wife cannot be made to testify against her husband. Jack happily agrees to the arrangement.
