M.I. High: High School Spy Movie

Spy drama set in a school. The spies receive some intelligence about demanding filmmaker Lars Von Tripod: every time he makes a film a valuable artefact is stolen. The team lures Von Tripod to St Hope's with a script that features three school pupils who are also spies. Rose and Oscar will audition for parts in the film in order to keep an eye on the bait. But things go terribly wrong when neither of them gets past the first audition. How can Rose and Oscar keep an eye on the artefacts when they're not part of the film?
