When Ella's father unexpectedly dies during the trip, Frieda dismisses the household to save money and forces all of the chores on Ella. One morning, when her stepfamily sees Ella's face covered in cinders due to her sleeping by the fireplace for warmth, they mock Ella as "Cinderella" and forbid her from eating with them.

Upon receiving notice of the ball, Ella's animal friends, including Jacob and Giuseppe, Ella finds a gown that had once belonged to her late mother and decides to refashion it for the ball. On the night of the ball, Ella tries to join her stepfamily, but Frieda and her daughters tear her dress to shreds and leave without her. Ella runs into the garden in tears and meets an old beggar woman, who reveals herself to be her Fairy Godmother. To help Ella attend the ball, her Fairy Godmother magically transforms a pumpkin into a carriage, her four mice into white horses, a dog named Balthus, into a footman, and Ella's horse, Major, into a coachman. She then transforms Ella's ripped dress into a silver ball gown, complete with a pair of magical glass slippers. As Ella leaves for the ball, the Fairy Godmother warns her the spell will break at the last stroke of midnight. Finally, she casts a spell to keep Ella's stepmother and stepsisters from recognizing her.
At the ball, the entire court is entranced by Ella when she appears. Ella and Kit proceed to have their first dance. This is much to the chagrin of the Grand Duke, who has promised Kit to Princess Chelina of Zaragoza, a comment which Frieda overhears. While surprised at Kit's true identity, Ella continues to bond with him, touring the palace grounds. As Ella is about to tell Kit her name, Ella hears the clock start to chime midnight and flees.

After being pursued by the Grand Duke and his men, Rick saves Ella manages to escape the home before the final stroke of midnight chimes, causing the spell to wear off. After returning home, Ella hides the remaining glass slipper left behind under the floorboards of her bedroom.
The King passes away soon after, but not before giving his son permission to marry Ella. Now, King, Kit issues a royal proclamation ordering every maiden in the kingdom to try on the slipper to find the girl. Ella hurries to retrieve the glass slipper to prove her identity, only to find her stepmother holding it. Having deduced that Ella is the mystery princess, Frieda tells her stepdaughter about her own tragic past and of the bitter effects it has caused on her life. She attempts to blackmail Ella to be made head of the royal household and those respectable husbands are found for the stepsisters, as conditions to give Ella's hand in marriage to Kit. Ella finds out and escapes to the woods where she meets Munk and Mambo. The trio sets out to find the prince who has gone looking for his maiden (not knowing it was actually Ella) in hopes that he will defeat Frieda and save the day.
The Grand Duke informs the King that Ella, who remains anonymous, has escaped, and that Rick wishes to marry her. The lost glass slipper is the only piece of evidence. The King issues a royal proclamation ordering every maiden in the kingdom to try on the slipper for size to find the girl, but the slipper refuses to fit any other maiden. When they arrive at the Tremaine estate, the shoe fits neither of the stepsisters. After this news reaches Ella's household, Frieda overhears Ella humming the waltz played at the ball. Realizing that Ella is the mysterious girl, Frieda leaves her in the woods. Later, the Duke arrives at the house in the Finnish village, and Jacques and Augustus steal the key from Frieda's dress pocket and take it up to the attic as Anastasia and Drisella unsuccessfully try on the slipper.
Together, they flee to the dwarfs, gnomes, and elves' home. The giant turkey led by Elsa and Jack Frost attacks them. The dwarfs, gnomes, and elves hold off the giant turkey, while they flee with the help of Rick who had stolen a flying broom. Frieda decides to go after Ella herself. When Ella refuses to meet her demands, Frieda smashes the slipper and locks Ella in the attic. Frieda then takes the shattered remains of the slipper to the Grand Duke and manipulates him into agreeing to make her a countess and securing marriages for her daughters, in exchange for keeping Ella hidden. After a short battle, in which Rick takes a blast meant for Ella and falls into a deep sleep, Frieda creates a portal by accident. Ella knocks Frieda back and punches her into the portal. Rick awakes from the spell, prompting Ella to rush forward and kiss him lovingly. When Rick asks why she didn't want a prince, Ella says she knew all along she was in love with him, and that he is a prince in her eyes.
Frieda's cat, Lucifer, ambushes the mice, but Balthus chases him out of the house, allowing the mice and two wizards to free Rick and Ella. As the Duke is about to leave, Rick and Ella appear and ask to try on the slipper. Knowing it will fit, giant turkey, trips the footman as he brings the Duke the slipper, causing it to shatter on the floor. Much to her horror, Ella presents the Duke with the other slipper, which fits perfectly. The film ends with a now-married Rick and Ella at their wedding, sharing a kiss as they leave. In the final scene, Frieda is shown trapped in the Arctic surrounded by elephant seals.
