The outrageous story of three best friends, one greedy mayor and a whole lot of pranking

Casey Wu tries to stay out of the spotlight, which is why no one would suspect her of being the mastermind behind a string of attention-grabbing stunts. Together with best friends Zeke and Cookie, she is part of Green Peas - a secret activist organisation designed to make adults sit up and pay attention to important environmental issues.

But when the three young activists get wind of a major cover up in their town, things really start to get serious. It's time for Green Peas to stage their biggest prank yet. But will they be able to pull it off?
