Princess, Barbie, Mistaken Identity, Prisoner, Talking Animal
In an unnamed kingdom, a blonde princess and a brunette pauper are born simultaneously and grow up unaware that their facial features are identical to each other. The princess, Anneliese, craves freedom from her royal duties, especially when she is informed by her widowed mother, Queen Genevieve, that she must marry the wealthy king of a nearby kingdom because their own royal treasury is nearly bankrupt. The Pauper, Erika, craves a different sort of freedom as she is an indentured servant at the Madam Carp's Dress Emporium to work off her parents' debt, but dreams of becoming a singer.
Unbeknownst to the royal family, the royal advisor Preminger is responsible for their near-bankruptcy. His minions Nick and Nack have been stealing gold from the royal mines for some time, which is what led Queen Genevieve to believe she is nearly bankrupt. Preminger plans to announce his newfound wealth to Queen Genevieve, which he believes will allow him to marry Princess Anneliese. When Preminger learns that Queen Genevieve has approached King Dominick of Dulcenia to marry Anneliese, he decides a change of plan is in order. Preminger orders Nick and Nack to kidnap Anneliese, so that Preminger can stage his "rescuing" her, hoping that Queen Genevieve will be so happy that she will give him Anneliese's hand in marriage.
Though she agrees to marry Dominick out of duty, Anneliese and her tutor, Julian, are in love with one another, though they are unaware of each other's feelings. To cheer her up, Julian decides to take Anneliese into town for a last taste of freedom. The princess crosses paths with Erika and the girls are shocked to see how identical they are, the only differences between them being their hair colour and the crown-shaped birthmark on Anneliese's right shoulder. The girls quickly become friends as do their cats, Serafina and Wolfie.
On the same night, Anneliese is kidnapped and a fake letter is left on her desk stating Anneliese "ran away" to avoid marrying King Dominick. Julian suspects she was kidnapped by Preminger, so he asks Erika to impersonate as the princess until he can rescue the real Anneliese. Erika agrees to the temporary ruse to help her friends, and surprises Preminger when she arrives to welcome King Dominick. Dominick and Erika fall in love, despite Erika's fear of being thrown into prison when revealed that she is an imposter.
Anneliese manages to escape from Nick and Nack, but is turned away from the palace by a guard who believes "Anneliese" is in the palace with King Dominick and the Queen. Madam Carp mistakes Anneliese for Erika and locks the princess up in the Dress Emporium. Suspicious of Erika's impersonation, Preminger finds that Anneliese has escaped from the cabin where she was held captive. Julian, who had followed Preminger, is captured and imprisoned in a mine. When Preminger learns that Anneliese is at the Dress Emporium, he traps her in the gold mines with Julian.
Upon returning to the castle, Preminger exposes Erika as a fraud and claims that she had conspired with Julian to kill and replace the real princess. Erika, unable to prove her good intentions,is locked away in a small cell by the queen. After convincing everyone that the princess is dead, Preminger persuades Queen Genevieve to marry him to save the kingdom, who agrees only because she cannot see any other option. Erika manages to escape from her cell and bumps into Dominick, who reveals that he doesn't believe that Preminger is telling the truth. Elsewhere, Anneliese and Julian confess their love for each other and work together to escape the mines.
At the queen's wedding, Anneliese arrives in time to stop the marriage and reveals Preminger's deceit. When he tries to flee on horseback, his horse sends him flying into the wedding food and he is arrested. After confessing to her mother that she loves Julian and does not wish to marry King Dominick, Anneliese presents to the queen a solution to the kingdom's gold shortage: the rocks discarded by the miners actually hold amethysts and the mine is full of them.
Dominick confesses to loving Erika for who she is and if she should choose to, he would be willing to marry her. Erika, freed from her debt to Madam Carp thanks to Anneliese, chooses not to accept marriage just yet and achieves her dream of being able to sing around the world. After several months, she realizes that the place she would really like to sing is among her friends. She returns and marries Dominick while Anneliese marries Julian in a double wedding, along with Wolfie and Serafina.
