Alex Rider (Alex Pettyfer) is a British teenager, whom MI6 recruits into its ranks, for his skills as a linguist, scuba diver, sharpshooter and martial artist are perfect for a career in espionage; his first assignment is to investigate billionaire Darrius Sayle (Mickey Rourke), who may have a nefarious motive for his recent donation of megacomputers to all of England's schools.
