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?
