Aaron Spelling's acclaimed series stars James Broderick and Sada Thompson as Doug and Kate Lawrence, heads of a typical 1970s family whose joys and sorrows are explored with atypical grace and gravitas. With their children -- the ever-searching Nancy (Meredith Baxter), rebellious teen Willie (Gary Frank) and young Buddy (Kristy McNichol) -- the Lawrences journey along life's sometimes agonizing route, buoyed by the love of family.
