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.
Mitchell and Cameron plan an evening with the whole family to break the happy news that they're attempting to adopt another child. However, things go wrong when they realize Lily may not take well to another baby in the house. Meanwhile, Claire and Jay are each focused with proving a point.
