At the airport, Gordo meets Isabella, who is upset that someone is impersonating her. She and Gordo realize that Paolo is planning to have a nervous Lizzie unknowingly sing live at the concert (as Isabella actually does), creating the impression that Isabella is a fake, which would damage Isabella's career and embarrass Lizzie. Gordo and Isabella rush to the concert to stop him. When Lizzie's parents arrive in Rome, Ms. Ungermeyer learns that Lizzie is missing. Ethan reveals that she is performing at the Italian Music Awards, and Lizzie's family and the class also rush to the concert. Backstage, Gordo and Isabella find Lizzie preparing for the show and warn her about Paolo's scheme. Lizzie refuses to believe them at first, but Isabella convinces her that Paolo is using her. Ms. Ungermeyer gets the class (and Lizzie's family) into the concert by pushing her way through the bouncers.
