Greg Heffley has gotten himself into a lot of trouble. Greg is the main suspect in the destruction to the school's property. But here's the crazy part: he's completely innocent.

Greg knows he'll have to face the consequences once the snow melts, but is there any punishment worse than being confined indoors with your family for the holidays?
