After Bob meets Mary Fisher, a narcissistic romance novelist, at a dinner party, they begin an affair. Ruth, aware of the affair, confronts Bob while his parents are visiting, and Bob leaves her. As he packs his suitcase, he says his assets are his home, his family, his career, and his freedom. Angry, Ruth vows revenge on him and Mary.
