Based on the best selling young adult adventure series of books by Anthony Horowitz, this story concerns Alex Rider (Alex Pettyfer), a 14-year-old orphan who has been unwittingly trained all his life by his uncle with the skills to become a secret agent - scuba diving, mountaineering, martial arts and so on. When his uncle (Ewan McGregor), an MI6 agent, is killed, Rider learns the truth and finds himself forced against his will to take on a dangerous mission for the British secret service. Using the tools and gadgets of the trade, in the vein of 007, Alex must infiltrate the lair of billionaire and possibly evil mastermind Darrius Sayle (Mickey Rourke) in order to stop him from releasing a biological weapon upon all of England via his brand new, high tech Stormbreaker computers.
