Greg Heffley finds himself thrust into a new year and a new school where
undersize weaklings share the corridors with kids who are taller, meaner and
already shaving. Desperate to prove his new found maturity, which only going up
a grade can bring, Greg is happy to have his not-quite-so-cool sidekick, Rowley,
along for the ride. But when Rowley's star starts to rise, Greg tries to use his
best friend's popularity to his own advantage. Recorded in his diary with comic
pictures and his very own words, this test of Greg and Rowley's friendship
unfolds with hilarious results.
