When gifted singer-songwriter Charlotte Banks (Aly Michalka) asks new kid in town Will Burton (Gaelan 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, 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 Sam (Vanessa Hudgens), who plays a mean guitar and has a voice to die for. When disaster strikes, its time for the band to make a choice: Do they admit defeat, or face the music and stand up for what they believe in?
