Pete likes to play pranks. It doesn't matter what it is as long as it gets a laugh. When he impersonates his vice-principal on a radio call-in show, he goes too far and is suspended from school. Pete's parents send him to spend the summer working with his uncle, a whale-watching guide in a tourist town far from the city. When a whale is injured by a reckless tour guide, Pete struggles to save the animal. Then Pete has to pull the most important prank of his life to bring the guide to justice.
