One big (straight, gay, multi-cultural, traditional) happy family.
The Pritchett-Dunphy-Tucker clan is a wonderfully large and blended family. They give us an honest and often hilarious look into the sometimes warm, sometimes twisted, embrace of the modern family.
When Gloria's mother and sister visit, they bring traditions, baby names and family baggage; Phil helps the kids with their problems; Mitchell and Cameron try to correct Lily's bad habits.
