The action takes place in Spain and Puerto Rico during the early 19th-century reign of Ferdinand VII. The Duchess of Arrogan (Irene Rich) is the victim of the machinations of court "climber" Countess Veya (Myrna Loy). The Countess arranges to hide the king's enemy, Duke Cordova (Forrest Stanley) in the Duchess's room where he is discovered resulting in the banishment of both to the colony of Puerto Rico, and the Duchess's estrangement from her powerful husband. In exile the Duchess successfully but cruelly manages her extensive land holdings, nursing bitterness against all men, while Cordova becomes the bandit El Blanco. The two are thrown together and begin an affair. The Duchess's daughter Laska (Florence Fair) arrives, fleeing an unwelcome marriage to which the death of her father has left her vulnerable. Laska is kidnapped and rescued. The Duchess has a happy resolution, reunited with her daughter and Cordova.
