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.
When Arthur tries to sell Spence his adjoining burial plot, he somehow winds up selling it to Spence's mother, Veronica. Doug is assigned a new delivery route and is freaked out by a man at one of his daily stops who always answers the door wearing nothing but a towel around his waist. Meanwhile, Carrie takes on dog walking with Holly to make some money after being unemployed for several months, but immediately hates the job and hires a kid to do the walking for her.
