 Bobby - now a professional race car driver - enters the Nashville 500 but is seriously injured in a crash. The result has him paralyzed from the waist down and confined to a wheelchair. Bobby appreciates the support of his family but worries whether his fiancé, Tracy Wagner, will accept him and his disability. Tracy accepts very well, and by episode s end, the two are married in a ceremony inside the Brady living room. Greg considers changing specialties so he can help Bobby, but he later decides to stick with obstetrics. Subplots involve Marcia s husband, Wally losing his umpteenth job and in the aftermath, the Logans having to move in with Mike and Carol; Peter breaking off his engagement with Valerie (his girlfriend from "A Very Brady Christmas"); and Cindy catching the eye of her much older, Jewish boss, a widower with two children.
