When she is arrested for illegally charging attendees at an underground rave, she calls upon her godmother, Judy Lindendorf, to bail her out. So Mary can repay the loan, Judy employs her as a clerk at the library where she works. Mary reluctantly begins her new job while striking up a romance with Lebanon street vendor and aspiring teacher Mustafa. She gradually becomes very good at her job, in particular by mastering the Dewey Decimal System, but she gets fired after having sex with Mustafa in the library.
