Back in middle school after summer vacation, Greg Heffley and his older brother Rodrick must deal with their parents' misguided attempts to have them bond.
Middle school isn't all it's cracked up to be for self-described \wimpy kid\ Greg Heffley, who discovers a frightening new world teeming with boys who are taller, tougher and hairier than he is -- and decides to document it all in his diary.
Teddy Duncans middle-class family embarks on a road trip from their home in Denver to visit Mrs. Duncans Parents, the Blankenhoopers, in Palm Springs. When they find themselves stranded between Denver and Utah, they try to hitch a ride to Las Vegas with a seemingly normal older couple in a station wagon from Roswell, New Mexico. It turns out that the couple believes they are the victims of alien abduction. The Duncans must resort to purchasing a clunker Yugo to get to Utah, have their luggage stolen in Las Vegas, and survive a zany Christmas with Grandpa and Grandma Blankenhooper.
