When Greg Heffley's dad threatens to send him to military school if he doesn't stay out of trouble, Greg finds all-new ways to land himself in the doghouse! For starters, Greg's in over his head when he pretends to work at the swanky country club where Rowley's family has a membership. Things don't go much better on a father-son camping trip with the Wilderness Explorers, and then there's the Heffley's new dog, Sweetie, who fetches even more trouble for Greg.
