Andy invites the gang to come to a housewarming barbecue at his new digs in the suburbs. Once they arrive, PJ realizes her brother’s home is identical in every way to their home when they were kids. Also attending the barbecue are PJ and Andy’s parents: Eileen, their intrusive mother who spoils a big surprise, and Frank, whom Andy is convinced is the future version of himself. Brendan, Kenny and Mike desperately pursue a young single mom while PJ meets a nice young man from the city.
