Greg Heffley and his family take a road trip that turns into a series of side-splitting disasters. These involve: winning a pig in a contest; a seagull inside the car, hell-bent on eating Greg’s cheese curls; and the loss of all their money and credit cards, along with the car keys. They are forced to resort to desperate means –just to survive the ordeal!
It looks as if things can’t actually get ANY WORSE: Greg’s grandfather has taken his room because he can no long afford his own apartment; little brother Manny has a ‘no pants after dinner’ policy to encourage him to use the potty; Mom is trying to get the town to start a ‘No Gadgets Week’; and there is an impending school nature camp! How will Greg survive these trials?
