After making it to the top of the charts, members of the Silver Boulders, a popular tween rock band, find themselves undermined by internal squabbling as the bandmates seek different creative directions.

Rosalina comes back after her music cruise, but Michel (the French guy Rosalina kissed on the cruise) also comes back, criticizes Nat's music, and kisses Rosalina which Nat sees. This causes a heated fight between Nat and Rosalina in which they break up and Rosalina quits the band.
