When Danny, a young woman who grew up on the streets of London with no memory of her real family, is banished from her gang because she helped handsome rakehell Jeremy Malory steal back the jewels his friend lost in a card game, Danny demands that Jeremy give her a job. She is determined to become respectable in order to fulfill her dream of marrying and starting a family. Intrigued by her beauty and spunk, Jeremy hires Danny as his upstairs maid, although he wants her as his mistress.

Under the tutelage of Jeremy and his cousin Regina, Danny blossoms into a lady. Although she is drawn to Jeremy by passionate feelings she has never experienced before, she refuses to be anything more than a servant to him because she knows he is not the marrying kind. When Danny undergoes a Cinderella-like transformation and poses as Jeremy's new love in an attempt to help him avert a scandal, a few highly placed members of the ton remark on how familiar Danny looks. Now tongues are wagging, raising the question of her true identity, which threatens not only Danny's chances of capturing Jeremy's heart but her very life.
