The Andersons get new neighbors, the Johnsons, and Andy immediately starts fighting with Mr. Johnson. Meanwhile, the town of Cedar Knolls gets flooded due to severe rainstorms and the only house that isn't flooded is the Anderson's--thanks to a ten-foot wall that Andy constructed to keep the Johnson's dog out of his yard. Eventually the entire neightborhood seeks refuge in the Anderson home, much to Andy's dismay.
