Summer vacation is coming, Mickey (Demi Lovato) is excited and looking forward to spending a wonderful time at Camp Star with friends Sean (Joe Jonas), Nate (Nick Jonas) and Jason (Kevin Jonas) and writing music dreams together. However, what Mickey didn't expect was that a new Camp Star named "Camp Star" was rising, attracting most people's attention, even the Camp Queen Tess (Meaghan Jette Martin) was attracted to it. What should I do? At the same time, Nate fell in love with a beautiful girl named Dana (Chloe Bridges), and Dana's camp was Camp Star. In order to decide whether to stay or go, Mickey and others had to stand on the stage with the members of Camp Star. What awaited them was a wonderful game full of passion and challenges.
