The opening scene has Posey as her character Mary smoking a joint and collecting entry fees to an illegal rave she's throwing, leading to her arrest. When her librarian godmother Judy (Sasha von Scherler) bails her out, Mary goes to work at the library to pay back her debt, but without much interest in learning about being a librarian.
That is, until she smokes pot at the library one night and is inspired to learn the Dewey Decimal System, which she soon uses to organize her DJ roommate's records. Meanwhile, she romances falafel cart owner Mustafa, who shows up at the library for help with getting a teaching certificate, leading to a sexual encounter that costs Mary her job. It becomes apparent that Judy is envious of Mary's lifestyle, partying with friends and finding love.
