Dave Seville, a desperate song producer, meets three talking, singing chipmunks named Alvin (the awesomest one), Simon (the smart one), and Theodore (the cute one). Dave says that they can live with him if they sing his songs, but he later thinks that he made a terrible mistake when they ruin his house, his friendship with Claire Wilson (his girlfriend and next-door neighbor), and his job. Dave gets along with them better when they became very popular singers. Later on Dave's old friend and roommate, Ian Hawke trys to take the chipmunks away for fame and money. Eventually, Dave gets the chipmunks back, and he learns to consider them as his family. Also he and Claire get back together.
