Hamid-Ali, an Arab chieftain and bandit, captures an English baby during a raid on a caravan and, naming her Sheka, puts her in a harem to be prepared for the slave auction. At the auction, Sir Derek Anstruther, who has fallen in love with Sheka, disguises himself as an Arab and bids for her. After a fight, he kidnaps her and marries her at the English consulate. In England, Sheka has embarrassing moments conforming to British customs of dress and manner, which are intensified by the plot-tings of Derek's former sweetheart. When Derek neglects her because of financial worries, Sheka decides to sell herself to the libertine Duke of Wryden for the amount that Derek needs. Derek rushes to the duke's home when he hears of Sheka's plan, but after he learns that the duke investigated her and discovered she was his niece and an heiress to a large estate, Derek and Sheka are reunited.
