The film begins with the Chipmunks and the Chipettes—Alvin, Simon, Theodore, Brittany, Jeanette, and Eleanor—going on a cruise vacation with Dave Seville (Jason Lee). However, Alvin’s mischievous behavior causes chaos on the cruise ship, leading to a series of mishaps and, ultimately, causing the Chipmunks and the Chipettes to be stranded on a deserted island.
Unbeknownst to them, the island is not as deserted as it seems. They encounter a castaway named Zoe (Jenny Slate), who has been living on the island for several years. Zoe provides survival tips to the Chipmunks and Chipettes, and they join forces to find food and shelter.
