Cashier Clay Randolph is taken by Richard Dunlap, a swindling gambler, into embezzling $5,000. When Richard loses the money, Clay assumes the responsibility for the crime to protect his former sweetheart, Mary Singleton, who has married Richard. Mary's father, Col. Robert Singleton, gives Clay a copy of Mary Baker Eddy's Science and Health to help him start a new life, but the young man ignores the book and leaves for New York, where he becomes a gentleman thief. Mary and Richard soon leave the South and join him. When Steele, a millionaire, tries to implicate Mary in the supposed theft of a diamond necklace, Clay retrieves the jewels and returns them to the safe. Reciting from Science and Health , Mary telepathically warns Clay not to rob Steele's safe, and later Richard is killed while committing the crime Clay had planned. To redeem himself, Clay enlists in the army to fight in World War I, promising Mary that he will return.
