Edward Archer walks right into the den of lioness Charity Stonewright when he sails across the pond to South Carolina to resolve a property dispute for his cousin, the Duchess of Peckham. Astute but bookish, the Englishman isn't prepared for Charity, a strong-willed woman determined to prove the Charleston mansion is hers. And unbeknownst to Edward, Charity has a secret purpose. She is searching for the lost Stonewright fortune, hidden over 60 years ago, somewhere within the walls of the old, decaying mansion. Finding it will mean an end to the grinding poverty she's endured and fulfill her dream to establish herself in Charleston society as a wealthy heiress.

Drawn to the mysterious woman, Edward is increasingly torn between duty and his growing love. But Charity seems determined to keep him at arm's length, stubbornly maintaining her distrust of him.

As the mysteries of the mansion threaten to tear Edward and Charity apart, they must learn to listen to their hearts and discover that the real treasure may be love.
