Charlotte (Charlie) Lockwood, a quirky sarcastic 18 year old girl, along with her best friends, Allison (Allie) Carter, Madison (Mady) Jones, and Kennedy (Kenny) Brown, are in a girl rock band called the Heartbreakers. Having opened for major artists, such as One Direction, Ed Sheeran, etc. they decide to take a two week vacation in Australia. But everything quickly goes down hill when the girls bump into their rival band, Skyline. Both groups despise each other because of what happened at the AMAs two years ago. And so they get into a huge fight, one that ends up on the internet, and Simon Cowell, both groups' manager, forces them to live with each other for the rest of the summer, to sort out their priorities.
What will happen in these weeks? Love? Anger? Laughter? Jealousy? Hatred? or Friendship?
