The Border Rider

Diablo and a dangerous band of outlaws raiding into Mexico steal a wagonload of gold coins. They escape into Arizona territory where Diablo buys a large cattle ranch and becomes a respectable rancher named Robert Marlow. With his eye on another ranch that borders his, Robert decides to court Mary Callahand, the daughter of the wealthy rancher. Meanwhile a lone border rider the Mexicans call El Jinete receives a mysterious set of pistols to defend those who need protection. He settles into a secret hidden valley to raise horses. When he rides to town for supplies, he is ambushed, and left for dead. Mary, about to say yes to marry Robert Marlow, finds a stranger on the road to her ranch. When the wounded man awakens, they find he has amnesia and Mary is falling in love with him. Now the deadly duel for the woman and land begins.
