Babbit works for The Boss. He is a klutzy, left-footed, messenger and errand runner, nicknamed "The Rabbit". He accidentally loses the "Protection Book" at the Metro Library while there, with his nephew. The Metro happens to be the "Titanic" of all libraries. The "Book" could put The Boss away for life! In an effort to find the book, Babbit and The Boss's son Joseph, rope the whole crazy gang into going to the Library to find it, before Officer Maren or anyone else, lay their hands on it.
The adventures that follow are a recipe for havoc, chaos, and disaster.
