Riders of the Range (1923)

Martin Lethbridge, president of a cattlemen's association, is called upon to investigate reports of a growing number of cattle raids. The prime suspects are the sheep ranchers, led by Gregg Randall, who in turn blame the cattlemen for increased casualties among their herds. Complications set in when Martin falls in love with Gregg's daughter, Dolly. However, Martin ultimately prevails against a secret society of dishonest cattlemen, exposes Blunt Vanier as the cause of conflict, and marries Dolly.
