In a small town, a half-Indian ranch owner named Frank Madden, disguising himself as a white man, clashes with the Shipley brothers, who are found not guilty of lynching three Indians by an all-white jury.

Frank is wrongly accused and imprisoned, prompting the Shipleys to assemble a lynch mob to storm the jail.
