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 Carrie meet the neighbors after a hurricane destroys both of their backyards. Carrie breaks their hearts by telling the truth and rejects the idea of a combined backyard. So the neighbors retaliate by disrupting their privacy by making an aboveground pool in a small space. But as Carrie tries to mount a lawsuit, Doug can't deny the temptation and joins the other side. But before the pool goes down, Carrie takes a quick swim and later, Doug tries to enjoy the lawn sprinkler.
