Three's definitely a crowd for parcel post deliveryman Doug Heffernan (Kevin James), whose newly widowed father-in-law, Arthur (Jerry Stiller), has moved in with him and his wife, Carrie (Leah Remini). Doug's no longer the king of his domain -- the renovated basement that houses his beloved supersized TV set -- let alone the king of Queens, where he lives. Can they all just get along?
When Doug hears from Carrie that Deacon's ex-wife wants to reunite with him after a two-year separation, he can't decide whether or not to give Deacon the heads-up. When Deacon informs Doug that he just met a beautiful stewardess and is spending the entire weekend with her, Doug decides not to tell him about his ex-wife's plans to reunite with him. But when Carrie discovers this, she demands that Doug tell Deacon so he doesn't ruin his chances of getting back with Kelly.
