Life’s good for deliveryman Doug Heffernan, until his newly widowed father-in-law, Arthur, moves in with him and his wife Carrie. Doug is no longer the king of his domain, and instead of having a big screen television in his recently renovated basement, he now has a crazy old man.
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.
