Source-derived summary

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.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “M.I. High”, the useful work is to connect “british teen action television series” to the records capable of establishing context and consequence.

Evidence profile

Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Aug 10, 2026. The linked authority identifier is Q1040434. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2007, 2011, 2013 and 2014.

Critical limits

Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
