Alvin and the Chipmunks: Chipwrecked follows Alvin, Simon, and Theodore, along with their friend Dave (Jason Lee), as they go on a cruise together. Although the Chipmunks initially have a great time exploring the ship, they get into a little too much mischief and an accident occurs. The Chipmunks, their friends the Chipettes, and Dave are shipwrecked on an island with the evil Ian (David Cross). The crew fears that there is not much hope that they will be rescued and set about to make the island their home. While exploring the area, they come across a beautiful but unstable woman named Zoe (Jenny Slate). Although she originally tells the Chipmunks that she has been on the island for a very long time, she is really there looking for treasure. Chaos ensues when Zoe kidnaps one of the Chipettes, and the others try to save her while simultaneously trying to find a way home.
