Two boys from opposite worlds—a poor pauper named Tom Canty and Prince Edward, heir to the English throne—accidentally switch places. Each struggles to survive in the other's unfamiliar and often harsh life, learning firsthand about injustice, poverty, and the heavy responsibilities of power. Their adventure becomes a race against time as Edward tries to reclaim his rightful place before a coronation he cannot attend. Through their eyes, we see that a person's true worth comes from their character, not their title or clothes.
