"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.

Christine admits she is attracted to Stan (Andy Richter), with whom she serves lunch at Ritchie's school.

Ritchie's raffle prize of a playdate with his teacher (Blair Underwood) thrills Christine, until Richard's prescheduled father-son plans threaten to spoil the fun.

Christine and Richard must make some sacrifices to pay for increases in Ritchie's school tuition; Matthew considers some extreme changes.

Christine struggles over what to do when Ritchie does a poor job on an important homework assignment.
