While The Chipmunks are on tour in Switzerland, Brittany is depressed about The Chipettes’ relative lack of fame. To cheer her up, Alvin arranges for the ultimate Swiss publicity stunt: the gang will climb the Matterhorn and the girls will give a concert at the mountain’s peak. Meanwhile, Dave becomes worried and begins to search for them. On the way to the top, they become trapped in an avalanche as a result of Alvin's yodeling. The group digs themselves out before eventually being rescued. The Chipettes' fame increases as a result of their mountaintop performance, which also starts a very wet fashion craze.
