"Old Christine" (Julia Louis-Dreyfus) is a divorced mom who has a handle on her career and motherhood -- and a pretty good relationship with her ex-husband -- until he introduces his new girlfriend, a younger woman, also named Christine. Old Christine lives with her son and her brother, and runs a gym, and her life is a constant struggle to keep up with everyone else.

After the business she shares with Barb turns out to be profitable, Christine is put between a rock and a hard place deciding whether to spend her share of the money on herself or on charity.

Christine tries to teach Ritchie's class some street smarts but ends up stranded at a subway station.

Christine decides Ritchie deserves to go on a family vacation like his friends, but her plans to take him to Florida don't turn out quite as she had intended.

Christine takes a cranky, pregnant New Christine to a salon for some pampering while Richard plans a surprise wedding.
