Greg Heffley would be your average, every-day guy. Except that he gets teased by his older brother Rodrick, in trouble because of his younger brother Manny, criticized by his parents, and so much more.
Greg does not have much popularity when it comes to school. Ironically,Greg's crush (Holly Hills) is the most popular girl there. Greg attempts to impress her but he ends up embarrassing himself each time he does.
Gregs father soon becomes jealous of his bosses children because his sons arent as athletic as they are. His father threatens to send Greg to a military school in order to make him more of a man.
Greg starts to hear his friends talk about how awesome this summers going to be, and he cannot agree with them because might have to attend military school. What Greg found even more disappointing was when he remembered that he had to go to his repulsive neighbors house party. Come to find out, Gregs father also did not want to attend that party and if Greg could come up with an excuse for them to go home early, his dad would do him a favor.
During the party, Manny opens up their neighbors gift from the gift table, and finds a blanket. Greg makes a plan to take the blanket from Manny. With Manny being as feisty as he is, he threw the blanket over the railing and Greg jumped for it with his pants resting down on his ankles.
The next morning, Gregs dad decides not send him to military school as a favor for him saving them from that crazy party.
