Movie plot title: Agent Cody Banks 2: Destination London Movie plot: Agent Cody Banks (Frankie Muniz) attends summer camp, actually a secret facility for training CIA teenage agents. When a group of CIA soldiers attempt to abduct head counselor Victor Diaz (Keith Allen), Cody helps him escape, mistaking the CIA operation for a training exercise. The director informs Cody that Diaz stole disks containing plans for a secret mind-control device, and sends Cody to recapture him. In the United Kingdom, Cody poses as a summer orchestra student at the Kenworth estate to spy on owner Lord Duncan Kenworth, suspected of working with Diaz, supported by his handler, Derek (Anthony Anderson) and Kumar, Derek's right-hand man, who are disguised as a chef hired by Lady Josephine Kenworth and a taxi driver respectively. Whilst keeping his mission a secret from his fellow students, Cody sneaks around the estate and confirms that Diaz and Duncan are working together and that they have a working prototype of the mind control device, evidenced when Duncan makes a dog serve drinks and play the piano. The next day, Cody breaks into a lab owned by Duncan, where he sees the finished device: a microchip inserted as a filling into a tooth cavity by dentist Santiago. Shortly afterwards Cody and Derek chase Diaz, armed with a rocket gun, through London streets, but Cody is captured by the Metropolitan Police Service and taken to Scotland Yard. He is later freed by Emily (Hannah Spearritt), a fellow student who, similar to Cody, is actually a British MI6 undercover operative. While Emily buys coffee and soda, henchmen sneak up on Cody, knocking him unconscious by drugging him with spray. They kidnap him and implant him with the microchip. Under Duncan, Santiago and Diaz's influence, Cody meets the CIA director, who is then also converted. This is witnessed by Emily, who explains things to Derek. To get the microchip out of Cody, Derek cuts one of Cody's gadgets, exploding Mentos mints, into a precisely minuscule amount to safely remove it. The group later realise Diaz's plan: to implant all of the world...
