The Sign of the Cactus is a 1925 American silent Western film directed by Clifford Smith and starring Jack Hoxie, Helen Holmes, and J. Gordon Russell.
[2][3] 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.
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.
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.
