Out Of His Limit

Have you ever had a best friend who moved far away and promised to keep in touch yet they don't? Yeah... Me too. I'm Mackenzie Rose and my best friend Luke Hemmings left me behind in Melbourne while he went to America to fulfill his dreams. The last time I talked to him was when he told me he made it to America safely. It's been two years now and I still haven't seen him. What will happen when four carefree boys, one in particular, make a song about a girl who they think is out of their limit?
