Loving parents Steven (Michael Gross) and Elyse Keaton (Meredith Baxter Birney) raise their kids with open hearts and open minds. Growing up in the 1960s, Mum and Dad share a liberal point of view, and guide their family with the ideals and convictions of flower power at its best. Their offspring, however, have different ideas. Eldest son Alex P. Keaton is an over-achieving, hard-core Republican, and clashes with is parents at every turn. Mallory is a fashion-loving, boy-crazy teen struggling through high school, while little sister Jennifer is the precocious tomboy who always speaks her mind. Together, they share the moments that make them laugh, make them cry... and make them family.
