It's time for cheer leading tryouts and Lizzie McGuire decides to give it a try, but she fails while Kate gets on the team. Lizzie accidentally starts an ugly rumor, but her friend Miranda takes the blame. Lizzie must find the strength to confront Kate and tell the truth.
Lizzie is chosen to be a model at a teen fashion show. Soon, her newfound celebrity (and rumors of a magazine cover shoot) leads her real friends to act more like personal attendants, while the popular kids treat her like one of them.
It's Halloween, and Lizzie's school is organizing a big Halloween party. Too bad Kate's in charge, which means she gets the final say on everything. But when Kate disrespects Miranda's ancestral skeleton decorations, spooky things start to happen. Could it be the work of the spirits of Miranda's offended ancestors?
