Five years after the first film, Mia and Peter Thermopolis has just graduated from Princeton University's Woodrow Wilson School and are returning to Genovia with their bodyguard, Joe. There, they will await their reign once their grandmother, Queen Clarisse, abdicates. During Mia's twenty first birthday party, she dances with all the eligible bachelors in hope of finding a husband. She becomes attracted to a handsome gentleman named Nicholas. During the course of the night, Mia's tiara falls off and is caught by a Member of Parliament, Viscount Mabrey, who secretly plans to steal Mia's crown. While the Parliament is in-session the next morning, Mia and Peter stumble upon a hidden room that allows them to secretly listen in. Viscount Mabrey reveals his nephew, Lord Devereaux, is another heir to the Genovian throne. Despite Queen Clarisse's objection, the only way Mia can assume her duties as Queen is if she marries within the month. Clarisse invites Lord Devereaux to stay at the palace, while Mia is shocked to discover Lord Devereaux is actually Nicholas. Mia and Peter's best friends, Lilly Moscovitz and Harry, surprise them by visiting. Together, they pick through potential husbands. Mia eventually chooses Andrew Jacoby, Duke of Kenilworth, and days later, they are engaged. Mabrey plans to have Nicholas woo Mia and dissolve the engagement.
