繼那只脾氣壞又好吃懶作的加菲貓搞出了壹大堆笑話之後，大銀幕上的新壹代寵兒由三只古靈精怪的花栗鼠接手……故事開始於壹個生活在洛杉磯、雄心勃勃卻又懷才不遇的詞曲作家大衛?塞維爾所面對的壹系列窘境，他的制作人伊恩對於他的作品和女友克萊爾似乎都不甚滿意，也缺乏耐心，所以幹脆“冷藏”了他，對他不聞不問。就在大衛幾乎放棄了所有的希望之時，卻突然在自家的廚房聽到了輕快的節奏，循著聲音，他找到了艾爾文、西奧多和西蒙--三只在廚房偷吃、卻絕對擁有著與眾不同的才能的花栗鼠。
讓大衛差點驚掉了下巴的是，這些厚顏無恥跑到他家找能吃的東西的花栗鼠，不但說著壹口流利的英語，竟然還會唱歌，而且頗有音樂天賦……它們自顧自地在大衛的住所安了家，成了這個冷清的屋子裏的新寵物，吃飽住好的同時，順便幫助大衛創作了幾首全新的聖誕歌曲，***同演奏給伊恩聽。
不幸的是，同樣覺得花栗鼠會唱歌很神奇的伊恩，還看到壹條財源滾滾的致富之路，他為三只花栗鼠進行了最有效的包裝和宣傳，然後展開了世界範圍內的巡演，給它們安排了大量的工作，心中盤算的是要如何奴役它們，才能給自己帶來最大的經濟效應。為了讓自己心中的計劃壹路暢通無阻，伊恩借故成功地將壹直保護著花栗鼠的大衛趕出門外，讓他沒辦法再度參與進來。那麽，我們可愛的花栗鼠能在人類的貪婪中生存下來嗎？大衛又能否拯救這三只幫他趕走了孤獨的夥伴，趕在金錢至上的伊恩造成永久的傷害之前？其實答案，早在我們走進電影院之前，就已經非常明確了。
