Steven and Elyse Keaton, once 1960s radicals, now find themselves in Reagan-era American trying to raise a traditional suburban family. Son Alex P. Keaton is an ambitious young Republican, and his sister Mallory is a shallow victim of the corporate culture, obsessed with music, clothes and boys. Their only normal kid is young Jennifer, a bit of a tomboy. In later seasons, the Keatons add a fourth child, Andrew. Most of the comedy arose from the conflict between the liberal parents and the conservative children.

The entire neighborhood is catapulted into action when the Thompsons' home is vandalized.

The Keatons recall special moments while helping Andrew fill a "time capsule" with family memorabilia.

Alex faces a dilemma when Lauren returns to town, and they meet in the cafeteria with Marty.

The Keatons are concerned when Jennifer becomes obsessed with environmental issues.
