Banks masquerades as a musical prodigy to get close to a snobby, egocentric scientist in London who's the only person who can make the microchip work. Along the way Banks hooks up with a demoted agent and a cute-as-a-bug Scotland Yard operative. When Agent Cody Banks heads to England to catch an evil scientist who's stolen a mind-control device for his plot to rule the world and turning the world leaders into zombies!

Agent Cody Banks 2: Destination London is the sequel to the 2003 film Agent Cody Banks, and was released in the United States on March 12, 2004. Frankie Muniz was the only major returning star, with Hannah Spearritt now playing the love interest and Anthony Anderson as the sidekick. As the title suggests, the location had switched to London with Cody trying to recover a stolen software activating the government's mind control project.
