An elderly countess strikes a bargain with the devil and exchanges her soul for the ability to always win at cards. An army officer, who is also a fanatic about cards, murders her for the secret, then finds himself haunted by the woman's spirit.

During the last half of the 19th century writer Richard Darrell saves Don Carlos from two robbers, and is entrusted by Don Carlos to take a valuable necklace to Spain. Richard leaves his fiancé, Oriana, and starts the trip. He meets Wycroft, a henchman for Sir Francis Castteldow, an aristocrat out to steal Oriana from Richard. The latter is assaulted, robbed and nearly killed and, as a result, loses his memory. He marries a gypsy girl, Rosal, while Oriana, thinking him dead marries the dastardly Sir Francis. Everybody will meet again. Complications will arise.
