M.I. High - Season 3

The new team has to set aside their individual reservations about working together when they discover that the world's most famous monuments are being vandalised. The Eiffel Tower, the Taj Mahal and the Great Wall of China have all been covered in provocative art work which mocks the host country. Now it's jeopardising the worldwide anti-SKUL treaty.

New spies Carrie and Oscar are still trying to earn their stripes with espionage leader Frank London and the pressure increases as they are told that they are still on trial. Together with the more experienced Rose, they have to work against the clock to stop a mystery criminal who is robbing all the banks in the country.

Oscar's photograph has been uploaded onto the internet and has been seen by the wrong eyes - those of the Grand Master, who sends Agent X, the world's most notorious agent, after Oscar. Team boss Frank London has calculated that Agent X, who has never failed a mission, will be at St Hope's School in four hours and Oscar must escape.

The MI High agents are protecting Dr Wallis, the inventor of The Mind Machine, a device that turns bad people good. However, the evil Grand Master has got wind of the device and wants to use it to turn good people bad, and sends a SKUL agent to capture Dr Wallis and his invention.

As half-term approaches, Rose is on a training course and Oscar and Carrie are expectantly awaiting an exciting new mission at HQ. Frank, however, receives a call and suddenly sends them home. Disappointed and suspicious, Carrie and Oscar leave school. It must be something to do with Frank's incredible invention, the Dark Star, which emits darkness and can turn a large area pitch-black in an instant.

Jed Black, MI9's head of training, arrives at St Hope's to get the spies fit and they endure a day of exercise. Meanwhile, a strange newcomer, Luvabitz, arrives in his wurst van and hands out the free, greasy, delicious wursts. The kids and Frank become addicted and simply cannot get enough of them. As a result, they are getting fatter and fatter. Where will it all end?

It's the day MI9 has been waiting for - a chance to catch the Grand Master himself. He is holding a meeting of the 'big six', where six of the world's greatest criminal minds are gathering to decide who will be the next Grand Master. To help teen spies Rose, Carrie and Oscar track down their arch-Nemesis, MI9 sends them their most advanced gadgets yet.

Rose has been selected for the National Academy of Brilliance. It's a once-in-a-lifetime opportunity, but she is devastated - it means she has to leave MI High for good. Frank, meanwhile, fills the remaining spies in on their latest mission. Genius Dr Vince is selling his inventions to anyone who will buy them so Oscar and Carrie embark on an operation to investigate his laboratory.

Katrina Houseman thinks that the evil Uzhmanis stole her top secret project N80, a real life Neanderthal, and plan to clone him to create a Neanderthal army.

Someone is draining Britain's power at a rapid rate and the country is facing an energy crisis. The only hope is Raymond Stilt and his genius invention, The Glove, a renewable-energy generator that is entirely solar-powered. However, The Glove is not ready and needs testing, and the only people who can help are the MI High spies.

An international gymnastics competition comes to St Hope's with potentially disastrous consequences for national security and the Prime Minister. Carrie faces her most difficult mission so far as she is asked to exploit her friendship with her Boldovian pen pal and fellow gymnast Lena Larsson. Carrie must try to find out about Boldovia's cruel regime and what they are planning.

The spies put Flopsy, the Grand Master's adored pet rabbit, up for ransom. Surely the Grand Master won't be able to resist and Oscar will finally be reunited with his mum? Oscar's mum leaves a covert message in his favourite magazine revealing she is still being held captive by SKUL and is ill. Can the team find a way to get her back?

MI High reaches for the stars when the spies are launched into space, with no idea of how to fly the rocket. A SKUL space probe has landed on the moon and MI9 suspects SKUL is using it to spy on the world. The spies must find out exactly what SKUL is up to and put a stop to it.
