Alvin and the gang are back in this hideously titled follow up to Alvin and the Chipmunks. This time, Alvin, Theodore and Simon are facing a life away from their pal Dave (Jason Lee - who's reduced to a mere cameo in this sequel) after an accident at a concert lands him in hospital. Dave dispatches the helium voiced trio to live with his nephew Toby (Zachary Levi) - and as an added bonus, Dave decides it's time for them to go to school. Advertisement As if the peer pressure of fitting in at an American high school wasn't bad enough, the Chipmunks face a new threat - a female equivalent trio, the Chipettes, who are being masterminded by former manager Ian Hawke (David Cross) who's determined to get back into the big time and rain on Alvin's parade.
