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 asks Deacon and Kelly to accompany her and Doug to Florida for their visit with the in-laws so that they'll be forced to stay at a hotel instead of with Doug's parents. What looks like a perfect vacation turns into a nightmare when spring breakers invade the hotel, forcing Carrie and Doug to reconsider their future accommodations when visiting the folks. Adding to the misery is the great disappointment shown by Doug's mom over the fact that no one is staying at her house.
