TVRage's Family Ties guide.
It was set in Columbus, Ohio where one-time flower children Elyse and Steve Keaton still espoused the liberal values of the idealistic '60s, although they were now parents and professionals (she an architect, he the manager of public TV station WKS-TV). Their children's ideals were something else. Seventeen-year-old Alex was Mr. Conservative, habitually dressed in suit and tie and with a picture of William F. Buckley, Jr., over his bed. Mallory, 15, was into designer jeans, boys, and drunk food, while cute little Jennifer, 9, just wanted to be a kid. They were a loving family, though the kids never could understand those Bob Dylan records their parents kept playing.
Alex and Elyse need to have a talk after a blow up over his accepting a new job in NY, and his shunning of his family, calling him arrogant and inconsiderate. Come the next morning, Alex is off for his new life.
