Upon returning to his father's ranch from college, Bradley Blatchford encounters Sybil Hamilton, who is arriving in the ranch town to work as a schoolteacher. Soon after, Bradley's father becomes suspected of cattle rustling, but he vehemently denies the accusation. As Bradley and Sybil's relationship blossoms, Bradley catches a rustler in the act, only to discover that it is his own father. His father explains that he is grappling with an uncontrollable hereditary predisposition. Witnessing the scene, some acquaintances rustle cattle from Blatchford's ranch, branding it with Sybil's mark, and falsely accusing her of rustling and harboring a concealed past. Sybil reveals that her brother brought shame to the family, but upon learning the truth, George is forgiven and reconciled with her.
