Based on a short story by cowboy author Zane Grey and set in the shadow of Boulder Dam, The Fighting Phantom tells a tale of Arizona Valley ranchers driven from their land by greedy and ruthless landsharks - a classic clash between the pioneering West andthe powerful East. When the poor landowners realize they have lost everything - their homes and their savings, a likeable young rancher, Wade Benton (Kent Taylor) offers to help them, only to be framed and imprisoned by the same unscrupulous moguls. Justas these families are forced to ride away in a long, sad caravan, a mysterious rider appears, gathering evidence that may soon prove who really holds title to the land.
