Bill Mathews mistakenly comes to believe that his sweetheart, Sally Brown, prefers the company of his brother, Henry, to that of his own and dejectedly goes to the city, where he finds work driving a truck. Six months later Bill returns home; that very day, the Delno gang robs the bank and kidnaps Sally. Bill follows the outlaws in a plane and parachutes into their mountain hideout; he captures Delno's men and rescues Sally, who quickly convinces him that she has never loved another.
