The chipmunks--Alvin, Simon, and Theodore, of course--are working on a school play along with their partners in crime, the chippets. Something startles them on their walk home, and the anxious chipmunks accidentally trample through their neighbors flower garden. To make things worse, Alvin is convinced that their neighbor is no mere human, but a werewolf masquerading as a regular guy. It's not long before the trio and their pals are embroiled in a Scooby-Doo-esque mystery, complete with mysterious pawprints, and poor Theodore is worried he's a werewolf as well.
