The Peanuts gang is nervous about going to a new school, so Lucy starts her own. She soon learns that teaching is tougher than she thought—and that change can be a good thing.

It's the last day of school and 14 year-old Grace (aka "Twinkle Toes") has been dreaming of the ultimate summer vacation with her best friends, Sporty Shorty and Jordan. But when Twinkle Toes' Dad gets a once-in-a-lifetime opportunity to direct a Broadway musical, Twinkle Toes is swept from her small-pond suburban life and thrown in the hustle and bustle of New York City for the summer. As Twinkle Toes learns the ins-and-outs of the Big Apple and Broadway, she impresses the show's choreographer and is invited to be a part of the show's cast alongside the teenage starlet, Olivia Conners. But when Twinkle Toes gets a taste of the Broadway limelight, the chance for stardom overwhelms Twinkle Toes and the show is ruined! To make things right, Twinkle Toes must use all her creativity, smarts, and dancing skills to help her new friends and save the show!
