The summer before her seventeenth birthday, Calliope gets the chance of a lifetime when her father gifts her the ability to travel with him while he plays roadie for an up-and-coming boy band called IM5. While Calliope is excited and slightly nervous to spend time with the members of IM5, she's ready for the adventures on tour that her dad has always told her about. Little does she realize, the life of a struggling artist- well, lives of five -are much more complicated than she anticipated. She's going to have to do things she never expected, like play publicist to people older than her, learn some apparently very tricky dance moves, and maybe, just possibly, keep her feelings in check for the very popular blond bombshell of the group.
