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 is surprised to find his married best friend, Deacon, out with another woman. Meanwhile, Carrie questions her relationship with Doug because of their different views on cheating.
