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.
Carrie soon grows tired of Doug's forcing his new vegetarian lifestyle down her throat. Meanwhile, Carrie's boss wants to start discussing novels with her and Spence takes on some humiliating new jobs.
