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 feels sorry for Arthur and agrees to let him go to a cocktail lounge instead of to the weekly dance at a senior center. When Carrie finds out, she goes ballistic and turns her father's care over to Doug-a job he soon regrets taking on.
