Ella [Leslie Caron] is a lonely and misunderstood young woman living in a European duchy. She works as a lowly servant to her stepmother, the Widow Sonder, [Elsa Lanchester], and stepsisters, Birdena [Amanda Blake] and Serafina [Lisa Daniels]. Shunned by the town for her anti-social behavior, she earns the nickname "Cinderella." Yet she clings to a hopeful dream—that she will one day live in the palace—fueled by a fortune-teller’s prophecy her late mother cherished.
Prince Charles [Michael Wilding], the son of the Duke who rules the principality, returns home after years away studying abroad, and his arrival is marked by three days of festivities culminating in a grand ball. As the celebrations unfold, he finds himself recalling a moment from his childhood: a girl with unbearably sad eyes who lingered in his memory, a memory that feels somehow linked to Ella’s own quiet sorrow.
After a petty quarrel with her stepfamily, Ella escapes to her favorite secluded pool on the palace grounds. There she meets Mrs. Toquet, a colorful town vagrant who becomes her first true friend and ally. Mrs. Toquet is no ordinary wanderer; she carries the air of whimsy and mystery, and she seems to understand Ella’s longing in a way no one else does. When Ella returns the next day, eager to see Mrs. Toquet again, she instead encounters Charles and Kovin. They tell her they come from the Palace, and Charles—recognizing the distinctive lines of Ella’s eyes—begins to realize that the girl from his childhood may be standing before him again. Ella, unsure of his sincerity, initially thinks he is teasing her and impulsively pushes him into the palace pool.
The Sonder home soon hosts their wealthy Cousin Loulou, a visit that puts Ella back in the spotlight. The family plans to present Ella to their guest in a polished, proper light, but a barefoot Ella risks scandal. She recalls leaving her shoes at the pond and runs back to retrieve them, unexpectedly finding Charles waiting. She apologizes for the earlier push, and he apologizes for hurting her feelings. He offers her an invitation to the Ball and even gives her a brief dancing lesson. They share a moment—one that includes a quick, stolen kiss—before Ella slips away into the growing whirl of the palace soirée.
Before Ella leaves, Mrs. Toquet arrives with a pair of glass slippers and one of Cousin Loulou’s fancy ballgowns, having “borrowed” them for Ella’s use. She also arranges for a coach to take Ella to the palace and issues a warning: she must leave by midnight so as not to burden the coachman with other clients' schedules. The transformation is magical, but the clock’s countdown adds a tension that mirrors Ella’s internal resolve.
At the Ball, Ella is swept into a world of music and flirtation. Dozens of young men want to dance with her, yet she remains largely silent, focused on reaching the palace kitchens in search of Charles. When their paths finally cross again, Charles reveals his true identity, and the other guests note Ella’s exotic appearance, speculating that the stranger might be an Egyptian princess, partly due to her short hair. As the clock strikes midnight, Ella slips away, leaving behind a single glass slipper. Charles picks up the slipper, realizing it may prove the key to identifying the mysterious princess he longs to wed. A dramatic moment of flight ends with Ella’s coach overturning as she is knocked unconscious; when she wakes, she is back in her familiar surroundings, greeted by Mrs. Toquet, who reassures her that everything she borrowed has been returned.
The next morning brings its own whispers. Charles confides to his father that he has found the woman he wishes to marry, but Kovin seizes the moment to spread a misleading tale that Ella is an Egyptian princess. News travels quickly, and by dawn many believe that the Prince has chosen a royal destiny for Ella. Devastated, Ella considers escape once more, but a final encounter with Mrs. Toquet—who had orchestrated the magical night—confirms her place in the story. With a father’s respect and a prince’s promise, the news finally reaches the crowd: the glass slipper, found at the ball, will fit Ella, the woman who has captured the young prince’s heart.
In a jubilant turn of events, the gathered crowd bows as Ella and Prince Charles ride toward the palace. The revelation that Mrs. Toquet is Ella’s fairy godmother adds a final note of enchantment to a tale rooted in hope, resilience, and the belief that kindness can transform a life. The magical mentor fades away as quietly as she appeared, leaving Ella to step into a future she once believed was beyond reach, now joined to the prince she has chosen and the palace she has longed for.
