The Grey Devil

Jim Stewart, foreman of the Triple C Ranch, is staying out on the range one night, trying to find out who is responsible for the disappearance of several mares. Although a wild stallion named "The Grey Devil" is suspected, Jim thinks that rustlers are to blame. Because Jim's coffee has been drugged, he is not awake when several more mares are taken. When he awakens, he is accused of falling asleep on the job and is fired. Determined to learn who the rustlers are, Jim finds the Grey Devil and tames him. Eventually, Jim unmasks the rustlers as a gang headed by the ranch hand who has been his rival for the affections of the rancher's daughter. Jim bests the rustler in a fight and wins the hand of his sweetheart.
