In a freak soundclash, BB and Lady Lux switch bodies. Now looking like BB, Lady Lux tries to steal Freez and Mo’s instruments to help Vox harness the 13th note. Meanwhile BB, who looks like Lady Lux, desperately tries to convince Freez and Mo that they’re in jeopardy. Of course they don’t believe anything “Lady Lux” tells them, so BB enlists the aid of her old bandmates CC and DD to perform with her in order to foil the real Lady Lux’s plan.
