Art imitates life in the sitcom's fifth season as marriage equality comes to California, setting the stage for Mitchell (Jesse Tyler Ferguson) and Cameron (Eric Stonestreet) to finally tie the knot. And since nothing is ever easy for these guys, that means everything from the proposal to the preparations by wedding planner Pepper (Nathan Lane) are fraught with the usual shenanigans. But it's no less chaotic for the rest of the Pritchett clan as Gloria (Sofía Vergara) hires a nanny to look after baby Joe; Claire (Julie Bowen) goes to work for Jay (Ed O'Neill) at his company, which leads to shared secrets at an industry convention; Manny (Rico Rodriguez) and Luke (Nolan Gould) start high school; Alex (Ariel Winter) and Haley (Sarah Hyland) have a crush on the same pizza-delivery boy; and Phil (Ty Burrell), in an attempt to honor his late mother's wish that he visit the country where he was conceived, organizes a family trip to Australia. Celia Weston and Barry Corbin guest star.
