In a multi-storey library, people are going about their business, either studying or working. As one of the librarians is stacking some books, he hears some commotion caused by an unseen to him library patron. As the befuddled librarian tries to track down the source of the commotion, the original source sets off a chain to get others involved in his commotion, much to the surprise of unsuspecting on-lookers. But the librarian may just have to give-in and fall prey to what's happening around him.
