Isabelle is excited about starting her first year at Anna Hart School of the Arts, but her classmates are so talented -- especially her older sister, Jade. Isabelle loves ballet, but she wonders if she'll always be dancing in her sister's shadow. Isabelle's mood takes a leap when her mom asks for her help designing costumes for the Autumn Festival. Back in the dance studio, though, Isabelle still lags behind her classmates. Can she stop comparing herself to others and find a way to become her own kind of dancer?
