Middle school is not an enjoyable experience for preteen Greg Heffley (Zachary Gordon) but a horrid ordeal of social land-mines that he must bear. To do so, he devises schemes to win him the recognition and status he feels he deserves -- all of which fail miserably. Greg chronicles his misadventures, thoughts, and opinions in a diary to prepare for the day that he will no longer have to put up with nonsense.
