Ally McBeal, 28, and a recent graduate of Harvard Law School, is harassed on the job by a senior associate. When she confronts the partners, it backfires and she loses her job. On the street, she literally bumps into an old classmate, Richard Fish, who offers her a position working for his new firm. She accepts, despite her misgivings about his ethical standards. While being introduced to her new fellow associates, she receives the shock of her career.

The first case Georgia brings to Renee's new firm pits them against Cage and Fish. Georgia defends Newman's, an upscale department store against Steve Mallory, who worked as the store's Santa for seventeen years. Cage represents Mallory, who claims that he was wrongfully fired because Newman wants to hire a younger, thinner Santa. Meanwhile, Ally is haunted by visions of herself as a little girl. Ally manages to bring Georgia and Billy together to talk, and Billy sees that he wants Georgia back. But Georgia is not as eager to work things out yet.

Georgia blames "Cage & Fish" for the new Billy, and is suing the firm for the break-up of their marriage. She cites many issues as leading to Billy's breakdown and the ultimate dissolution of their marriage. However, during the court hearing they discover that the root of the problem lies elsewhere.
