When a conspiracy to capture the royal throne goes awry, a group of criminals resort to sinister means in order to kidnap the rightful heiress. Just as Princess Evelyn Cottington (Fiona Perry) is about to make her premier at a social event, she's rushed off to America for her own safety. It seems that she has an Aunt Fay (Bobbi Jo Lathan) who's off the royal radar and thus unknown to the thugs, and the plan is that the princess can hide there until she can claim her rightful place on the throne. Her aunt is kind-hearted and welcoming, with a cute little dog who loves the new visitor, but she's also goofy and unable to help Evelyn fit into her new surroundings. The princess, now disguised as a regular girl named "Olivia," attends a local school and becomes an object of ridicule.
Feeling sad, she decides to volunteer at a local carnival, where she notices a pony named Echo. He's bright and vivacious but also gets mistreated by the money-hungry carnival owners. The princess befriends the animal and teaches him how to jump, and for the first time in her new country she feels happy. Unfortunately, the carnival owner (Theodore, played by Bill Oberst Jr.) is the leader of the criminal gang. The whole time that the Princess has been in America, he and his henchmen have been trying to figure out which student at the school is their intended target. When he realizes that the pony's new caretaker is the princess, he can barely contain his evil glee.
The villains try their hardest to execute their plot, and the princess is forced to depend on her wits to escape their clutches. With no royal servants to depend upon, she realizes the value of being true to one's self. Her best friend, the pony, keeps her spirits up throughout it all.
