The film begins as Lizzie McGuire (Hilary Duff) prepares for her junior-high graduation with one of her two closest friends, David "Gordo" Gordon (Adam Lamberg). The other friend, Miranda, has chosen to skip the graduation ceremony in favor of a trip to Mexico City to visit relatives. During the ceremony, Lizzie trips onstage and accidentally brings the curtain down on her fellow graduates; this causes her to be teased by her ex-best friend, Kate Sanders (Ashlie Brillault), and her younger brother Matt (Jake Thomas). After graduation, Lizzie and her class embark on a trip to Rome chaperoned by their future high school principal, Angela Ungermeyer (Alex Borstein). To their dismay, Lizzie and Kate are assigned to the same hotel room.
