No sooner has Olivia (Michael Learned) taken a job as a door-to-door salesman to help make ends meet in the Walton home than she discovers she is pregnant...again. As John (Ralph Waite) wonders if the family can afford another child, his youngest daughter Elizabeth (Kami Cotler) makes no secret of her disappointment over being supplanted as the "baby" of the family. Ultimately, the family comes to accept what seems to be The Inevitable--and then an unexpected plot twist puts the situation in a whole new light. ~ Hal Erickson, Rovi
