Seventh-grade playwright Olive Henry is frustrated by her middle schools lack of appreciation for anything but sports. While the principal drones on and on during morning announcements about the sports teams victories, all non-athletic club meetings are relegated to the school basement, never to be mentioned on the loudspeaker. So Olive and her best friend, Reynaldo, hatch a plan to kidnap the schools capybara mascot, planning to return it, heroically, just in time for the schools pep rally and claim a reward: permission for their drama club to practice in the auditorium. And, hopefully, some overdue respect for the schools non-athletes. But when an animal-rights student activist and an undercover athlete with murky motivations join in the conspiracy, their plansalong with Cappy the capybaraveer wildly out of Olives control.
