M.I. High is a British action television series produced by Kudos for CBBC and created by Keith Brumpton. The series focused on a team of undercover teenage spies working for the fictional British secret intelligence agency MI9 who had to balance their school life with their jobs as secret agents. The line-up of spies was altered between the show's seven series. The series premiered on 8 January 2007 and originally ended on 21 March 2011 after five series, before being revived for a further two series that were broadcast between 7 January 2013 and 31 March 2014.

Premise

The series follows the adventures of secondary school pupils who work as undercover spies. The spies are led by an MI9 agent (first by Lenny Bicknall, later by Frank London) whose cover job is a school caretaker. The team must constantly save the world from domination by a variety of villains, whilst hiding their spy identities from their teachers and peers, and completing their school work. The identity of the overarching villains the Grand Master (Series 1–5) and the Mastermind (Series 6–7) remains a mystery within the show.
