As the ‘Munks and Chipettes scheme to find their way home, they accidentally discover their new turf is not as deserted as it seems.
The new home leads to character-changing adventures, on a scale new to the boys and to the “Alvin and the Chipmunks” films. As the story opens, The Chipmunks, Chipettes, and their eternally beleaguered guardian, Dave Seville, are en route, on a luxury cruise liner, to the International Music Awards.
