Due to internal disputes, the Teen Team has broken up. With no place left to go, Misty heads back to Earth to spend time with Jenny. Misty's appearance in school, however, earns her teasing from Brit and Tiff. Scorned, Misty convinces Jenny to get back at the Crusts via a prank war. The only problem, however, is that once Misty gets started on something, she doesn't know when to stop. She soon becomes mad with power, and Jenny must convince her pal that enough is enough before things get too serious.
