Like in the story of Cinderella, Sophie sees her dream come true one night. Behind her stepmother's back, she dresses like a queen and attends London's most important masquerade ball. What's more, she manages to capture the attention of Benedict Bridgerton, the most attractive and charming bachelor at the gathering. However, she soon faces her harsh reality again, that of an illegitimate, poor, and penniless daughter. Fate wants to give her a second chance when she enters Benedict's service, though he doesn't recognize her as the beautiful young woman he has been searching for for years. She is now a simple maid, unable to reveal the truth to him. The magic of that night seems lost forever, or perhaps not?
