Princess Mia (Anne Hathaway) returned to Genovia after graduating from college. The princess' arrival shocked the country, and Mia was very excited. However, at a royal hearing, the chief justice announced that the princess must get married before she can inherit the throne. Mia must get engaged within 30 days, otherwise she will have to give up the throne. The queen (Julie Andrews) had to rush to help Mia choose a husband with her assistants. After several choices, Mia finally got engaged to a young and handsome nobleman. Nicholas (Chris Pine), a young boy competing with her for the throne, had an unspeakable affection for Mia. The boy's uncle wanted Nicholas to seduce Mia so that she could not get married within a month, but the two young people had real feelings for each other.
