As Isabelle rehearses for the The Nutcracker she struggles with her pirouettes, in part because her castmate Renata points out her every mistake. Isabelle takes her mind off her troubles by helping to design costumes for the other dancers. She's distracted, too, by her older sister, Jade, who seems moody and withdrawn. When Isabelle figures out the problem, can she tap into her design skills to find a solution for Jade? And can Isabelle find the confidence to tune out Renata and polish her own performance, too?
