A young man who believes, because everyone else believes, that he is a half-breed Indian, meets and falls in love with a circus woman who is heiress to a fortune but does not know it. The man's love is reciprocated, but he is restrained by the supposed barrier of blood. His greatest enemy is his own half brother, who also is a suitor for the hand of the circus performer. The hero avoids all the traps his enemy lays for him, and when his and his sweetheart's identities are cleared up the two are married.
