London Jameson and Arielle Tanner are the complete opposites of each other. London is dark, mysterious, quiet, and a deep-thinker, whereas Arielle is bubbly, social, quick-witted, and a sassy optimist. These two couldn't be more different from each other, but they lead very similar lives. They are both involved in popular bands that tour the world, and they both love every second of it. However, Arielle is very disappointed when her girl band Sugar Shine takes an indefinite break. Meanwhile, London's band Moonrising has just lost their lead vocalist. The boys of Moonrising believe it's time for a change. Maybe a female vocalist. Maybe that sexy pink-haired chick from that band Sugar Shine. The boys are all for it...except London Jameson. So when London and Arielle are forced to share a hotel room while the band is on a summer rock festival lineup, it's the battle of the band members. Who can annoy whom the most? And what happens when London falls hard for Arielle?
