With the support of her husband Phil (Ty Burrell) and three children, she resolutely throws herself into the hopeless town council election. Claire's old father Jay (Ed O'Neill) tries to understand his Colombian wife Gloria and stepson Manny in his own way, but the facts show that cultural differences are not easy to overcome. Claire's younger brother Mitchell (Jesse Tyler Ferguson) and his gay lover Cameron (Eric Stonestreet) decide to adopt another baby boy. The two are struggling to find a suitable surrogate mother. At the same time, Lily's education problems also need to be worried about. What's worse, Mitchell is unemployed... In this season that starts with a farm vacation, the three families will each face some new changes and challenges, and the in-depth exchanges between each other will also make the family ties closer.
