Everyone has sibling struggles, even YouTube superstars...

Even with millions of followers, YouTube sensation Mia Fizz is a normal kid at heart. So when she and her BFF Briony make plans to attend the big dance at the local community center, Mia is thrilled-and her crush Finn agreeing to be her date just sweetens the deal! But things take a turn when Mia's younger sister, Sienna, insists on helping create her dance-ready look, accidentally leaving Mia looking worse than she could have imagined!

Mia's so embarrassed that she wants to skip the dance entirely, but doing that would mean disappointing Briony AND missing out on fun night with Finn! Can she find a way to forgive Sienna and embrace her new look before the dance?
