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.
