Sun Hi, Jodi and Corki start life at MacKendrick Prep boarding school with big expectations and bigger dreams… all of which might unravel because of a secret Corki refuses to reveal.

Sun Hi creates a band to launch her plan for pop music world domination, but Corki won’t join in case it jeopardizes her schoolwork… or her secret. Meanwhile, Caleb finds a place they can perform, but it needs a lot of work. Is he up to it?

While Caleb overhauls the roller rink into a dance club, Sun Hi and Jodi fail a test that puts them on academic probation. This means they can’t audition for the musical.

Sun Hi gets closer to finding out Corki's secret, while Valerie steals the dance moves Jodi choreographed for the girls' Wonderful Wizard of Oz audition.

It’s the band’s debut at Club Ry Ri, but Sun Hi loses her voice and Corki is too afraid to go on without a disguise. Can the band pull it out of the fire?

Head cheerleader Valerie and her entourage befriend Corki, who instantly leaves Sun Hi and Jodi behind. Will Corki come around or is she lost to the cool kids?
