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.
After Deacon and Kelly's separation, Carrie begins to wonder about her own marriage. She and Doug agree to put their sex lives on hold for a few weeks because Carrie feels that they should resolve arguments verbally, not always physically. Meanwhile, Arthur dates a woman who claims she was once Frank Sinatra's girlfriend.
