The Wild Pack is a band of animals living in abandoned rail tunnels and caves under the city. Led by the wolf Hamlet, they have just one goal: to live in freedom as they once did in the wild. Following Hamlet's dramatic escape from the zoo, this sequel finds the Wild Pack outsmarting humans time and again, even sneaking into the city's natural history museum in the dead of night, on a quest to discover where they are from. But there they are faced with the cruel zoo director, Mueller, once again. Scampering to safety-in a church, of all places-the Wild Pack hits upon a brilliant idea . . .
