On their a cross-country camping trip, Greg Heffley and his family find themselves stranded at an RV park that's not exactly a summertime paradise and when the skies open up and the water starts to rise, the Heffleys wonder if they can save their vacation--or if they're already in too deep.

Greg Heffley tells about his summer vacation and his attempts to steer clear of trouble when he returns to middle school and tries to keep his older brother Rodrick from telling everyone about Greg's most humiliating experience of the summer.

When snow closes Greg Heffley's middle school, he and his best friend, Rowley Jefferson, face a fight for survival as warring gangs turn the neighborhood into a wintry battlefield.
