 Mia, (Anne Hathaway) an awkward San Francisco teenager, has just learned her deceased father was the crown prince of Genovia. To keep the royal reigns from passing to another family due to a broken bloodline, the queen (Julie Andrews) seeks the favor of her estranged granddaughter in hopes that she will take her father s place as the crown princess. While Mia contemplates her future, her grandmother insists on turning her from a social misfit to a lady fit for the throne. What these two discover about each other is that blood is more important than bloodlines.
