Rancher William Norton refuses to sell his cattle for half price, so saloon owner and gang leader Jim Fletcher, contrary to the orders from his secret boss Willard McGowan, the town banker, has his men rob and beat up Norton. Unknown to anyone, Marion, McGowan's adopted daughter is really the daughter of Norton, who disappeared as a young baby when she and her mother were passengers on a stagecoach held up by McGowan. Chuck Saunders, Norton's foreman, goes after the gang for robbing his boss and eventually uncovers the truth regarding Marion's heritage.
