Veteran star William S. Hart both produced and starred in this western about a railroad-station agent who loses his job because of a villain's machinations. The villain (G. Raymond Nye) is a major stockholder in the railroad company and covets Hart's girl (Mary Thurman). Working as a ranch hand, Hart discovers that his enemy is actually the leader of a gang of train robbers. According to its publicity, Sand was President Woodrow Wilson's favorite Hart western.
