For Hank, fourth grade does not start out on the right foot. First of all, he gets called to the principal's office on the very first day of school. Then the first assignment his teacher gives him is to write five paragraphs on "What You Did This Summer." Hank is terrified-writing one good sentence is hard for him, so how in the world is he going to write five whole paragraphs? Hank comes up with a plan: instead of writing what he did on vacation, he'll show what he did. But when Hank's "living essay" becomes a living disaster, he finds himself in detention. Strangely enough, however, detention ends up becoming a turning point in his life
Hank decides to do a visual presentation on Niagara Falls, but when he floods the classroom, he gets detention.
