Times have changed for Ellen: Holly and Anita are gone, and Ellen now manages the bookstore on her own. While out with Adam, his date, and her aggressive childhood friend Paige Clark, Ellen accidentally chips a tooth while opening a beer bottle with her teeth and must go to a dentist Paige recommends. Ellen becomes attracted to him, but things go awry when she gets a whiff of the laughing gas that shows her true primal instincts. Meanwhile, Adam gnashes his teeth over Joanna, whom he dates, dumps, dates again--and wants to dump again.
