America's favorite furry brothers Alvin, Simon and Theodore are back. Because of a freak accident involving Alvin and Dave Seville, they go to live with Dave's cool cousin, Toby and they have to enroll in school like every other kid. School presents new challenges to these rock stars like dealing with peer pressure, football and of course, girls. By "girls" we mean the Chipettes who are managed by Ian Hawke, the Chipmunks greedy former manager who wants to turn them into the next big thing. There is rivalry between the Chipettes and the Chipmunks at first, but in the end they realize that they make great friends and a great musical team.
