Barbie as the Princess and the Pauper

In an unnamed kingdom, a blonde princess and a brunette pauper are born at the same time. Several years later, Princess Anneliese is betrothed by her mother, Queen Genevieve, to the wealthy King Dominick to save the nearly bankrupt royal treasury; however, she is in love with her young tutor Julian. The Pauper Erika is an indentured servant, working off her parents' debt at Madame Carp's Dress Emporium, but dreams of becoming a singer and seeing the world.

Unbeknownst to the Queen, the reason behind the kingdom's bankruptcy is her adviser Preminger has been stealing gold, emptying the royal mines. Upon learning from his henchmen, Nick and Nack, that the Queen has arranged Anneliese's marriage to King Dominick, he decides to make Anneliese mysteriously disappear, which will cancel the engagement; after which Preminger can pretend he has found the Princess, earning her hand in marriage, and allowing him to accede the throne and become king.

Julian takes Anneliese for a day out into the kingdom so that she can be free for once; there, she witnesses the poverty caused by the kingdom’s bankruptcy. Anneliese hears Erika, who is performing in the street to earn money for herself, but Madame Carp collects it as part of her debt. Anneliese and Erika meet and learn they are identical, apart from their hair color and the crown-shaped birthmark on Anneliese's shoulder. The two bond over their shared troubles and become fast friends. That night, Anneliese and her cat Serafina are abducted by Nick and Nack, who leave a forged letter saying she ran away.

Julian, doubting the letter, asks Erika to impersonate the Princess, saving the engagement while he investigates Anneliese's disappearance. Preminger is surprised when Erika, disguised as Anneliese, presents herself at the palace. King Dominick introduces himself to the disguised Erika; over time, the two fall in love, but Erika worries about what will happen if she is found out.

The real Anneliese escapes Nick and Nack, but is turned away from the palace because the guards think the Princess (Erika) is already inside. Mistaking Anneliese for Erika, Madame Carp forces Anneliese into her shop and locks her inside. A suspicious Julian follows Preminger to the house where Anneliese was being kept and overhears Preminger's plans, but is discovered and captured.

Anneliese has Serafina take her ring and a tag from the dress shop so someone can find her; unfortunately, Preminger and his dog Midas intercept her. Preminger takes Anneliese to the mines where she is imprisoned with Julian after Nick and Nack cause a cave-in. Preminger returns to the palace, where he exposes Erika as a fake and has her imprisoned. Preminger convinces the Queen that Anneliese is dead and that they must marry to save the kingdom; with no other options, she reluctantly agrees.

Erika escapes the dungeon by singing a lullaby, causing the guard to fall asleep, and taking his keys. She bumps into King Dominick who tells her that he doesn't believe Preminger's claims about her. Meanwhile, Anneliese and Julian find out how to restore the kingdom's resources with some geodes filled with crystals; the two then confess their love for each other. Erika's barking cat, Wolfie, unearths a mine shaft and the group escapes by flooding the room and floating towards the surface in a barrel.

At the Queen and Preminger's wedding, Anneliese arrives, proves her identity with her birthmark, and reveals the truth about Preminger. After a brief chase, Preminger is arrested along with Nick and Nack. Anneliese tells her mother that she wants to marry Julian and that they can help save the kingdom. Soon after, the kingdom’s prosperity is restored thanks to the crystals in the mine. Madame Carp goes out of business; and—with her debt finally paid—Erika leaves to become a renowned singer. After touring the world, Erika realizes where her heart is and decides to return home to marry Dominick. Anneliese and Erika have a double wedding and they and their husbands ride off in a carriage together.
