Drusilla Ives, a young Quaker girl living on an isolated island, leaves to become the servant of the spendthrift Duke of Guisenberry in London, who is the Lord of her village. She finds that she is attracted to the bustling city's night life, and when the duke discovers that she is a fine dancer, he helps her turn professional. In short order she becomes known as Diana Valrose, the city's favorite dancer. Unfortunately, her strict father and her Quaker fiancee, John Christison, back on the island find out about her newfound fame and career and strongly disapprove--her father places a curse on her and her boyfriend marries her sister Faith. Complications ensue.
