Tired of the beauty-pageant circuit, Selena Gomez tosses her tiara, pierces her nose, and auditions for the most unlikely of roles--drum major of the high school marching band.
Selena wins, but is forced to share the title with Justin Bieber, whose family has held the position for generations. Sure, Justin is hot, but because of his superior attitude, he and Selena are constantly arguing. That is, until they share more than just their half-time salute...
But as the drum majors' heated competition turns to sizzling romance, explosive rumors threaten everything--including the band's success. Love seemed to be a sure hit, but Selena and Justin may be marching straight into disaster.
