When gifted singer-songwriter Charlotte Banks (Michalka) asks new kid in town Will Burton (Connell) to manage her fledgling rock band, she appears to have just one goal in mind: go head-to-head against her egotistical musician ex-boyfriend, Ben (Porter), at the biggest event of the year, a battle of the bands.

Against all odds, their band develops a sound all its own with a real shot at success in the contest. Meanwhile, romance brews between Will and Sa5m (Hudgens), who plays a mean guitar and has a voice to die for.

When disaster strikes, it’s time for the band to make a choice: Do they admit defeat, or face the music and stand up for what they believe in?
