M.I. High - Season 2

Daisy, Blane and Rose return to St Hope's for a new term. After a thrilling chase, they catch Britain's most deadly threat, the Grandmaster, and are the toast of the secret services. But, while accepting an award at MI9, they witness the mysterious disappearance of the new American President during a magician's act.

MI9's Head of Technology, Quentin Flake, is at St Hope's to test new crime-busting computer Allen, who uses normal electrical devices to keep order. The redundant spies are totally put out that they have no work to do - aren't they the security service? But when a vacuum locks up 50p for littering, the team realises that Allen is a tyrant intent on taking over the school.

Britain's kids are going crazy for the fashion designs of Lorenzo Ferrago, but when green logos start appearing on children's skin, the school spies take to the catwalk to investigate the designer. They decide to infiltrate the House of Ferrago by posing as models. Once inside, the team discovers Ferrago is in cahoots with the Grandmaster.

School spy Blane is not impressed when Olympic hero Maximus Fiticus is invited to St Hope's sports day. Daisy joins in with the rest of the school when Maximus offers them the chance to use his special Powerlyser machine - she believes his machine really can make her look better. But, Blane realises the Powerlyser is actually stealing the kids' energy.

A child crime wave hits MI High. The teen spies have to discover why the crimes are being committed by supposedly well-behaved kids, and are baffled when Lenny has also seemingly turned to a life of crime.

MI High is in danger of being exposed when cameras go up around the school as part of a good-manners initiative. But, when footage of the pupils' terrible behaviour is edited and leaked to the media, it seems someone wants to make St Hope's look worse than usual. The spies realise the Minister for Schools is guilty of altering the footage because she hates kids.

The Grandmaster unleashes his own cold war on Britain, a nasty flu epidemic.

St Hope's is on red alert - nits are sweeping the country! But when they infest the school and the pupils take on the characteristics of criminals, the teen spies realise these are no ordinary nits. The chief suspect is nit nurse Nora Braithwaite. Daisy realises the only way to stop the infestation is to destroy the gross mother nit on Nora's head.

The team is shocked when they meet new undercover school spies and reformed criminals The Worm, Lewis Chuckworth and Violet, who have been retrained by MI9. But Rose decides they can't be trusted and her fears are confirmed when St Hope's is invaded by ninjas.

An audacious diamond thief is on the loose, and Her Majesty The Queen entrusts her Crown Jewels to MI High for safekeeping. Chief suspect is Ben Wheeler, England Captain and former diamond collector. Rose and Blane suspect that Wheeler is using his 'Sling Your Bling' campaign as a front for the thefts, and divert him to St Hope's for further investigation.

The MI High team is flown in to investigate the mysterious disappearance of a high-tech spy plane, which uses a cloaking device to become invisible. Embarrassed inventor Boris Ryfield is desperate for the plane to be found, so Blane goes undercover as a plane-collecting oil baron to track down the thief.

Plants across Britain have gained minds of their own and started cocooning builders and developers. When the spies suspect that Greenfinger, the evil villain behind the green invasion, is hiding out in a wood, Daisy cleverly persuades Mr Flatley to take them there on a school outing. But Flatley decides it's a boy's adventure and Blane must investigate alone.

An asteroid is heading for Earth and the only person who can stop it is government scientist Doctor Von Quark, but he has disappeared. Rose works out that a doomsday cult that wants the end of civilisation is behind the kidnap.
