(that's right, i went there. based losely off misadventures as a violist myself.)
at jakku high, rivalries run deep, and that includes internal rivalries. when new kid finn is indoctrined into the marching band ("JAKKU'S OWN MARCHING BANTHAS!!!) as a banner holder by percussionist rey, he has no idea what kind of political mess he's putting himself in the middle of, as tensions break out in the music department over which performing group gets the golden ticket to go perform in /motherfucking disneyworld/. as the orchestra attempts to sabotage their chances, rey and finn must work together not only for the good of their band, but also to rub it in those smug string player's faces. game on.

+ distractingly pretty star lacrosse player poe dameron keeps giving finn his varsity jacket to wear. finn thinks he's just helping a bro out. rey tries to explain that's essentially a marriage proposal in high school
+Ms. Organa is the forever unamused-yet-somehow-doting conductor of the band
+hux is the concertmaster of the orchestra and leads sabotage efforts. kylo plays the viola.
