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.
Doug and Deacon, who are out of work because of a strike, resort to playing sophomoric pranks, along with Arthur, to keep from going stir crazy. But they're driving Carrie and Kelly nuts. Eventually, Doug and Deacon return to work leaving Arthur alone.
