Ella, the third daughter of the Winslow family, appears to be a mistreated servant under her stepmother and two sisters. In truth, she is the mastermind protecting her family. When the prince announces a royal ball to choose a bride, Ella orchestrates a "Cinderella" scheme—a trick glass slipper, a midnight escape, and a kingdom‑wide shoe search. She maneuvers her elder sister Margaret into the palace as the future princess, sends her second sister Irene to Paris to pursue fashion, and stays behind to guard the family estate and her stepmother. Everyone believes the "Cinderella" longs to be queen. But Ella's only wish from the very beginning is to keep her home safe—and she never planned to leave it.
