An outwardly ordinary teenager finds himself suddenly thrust into extraordinary circumstances upon discovering that his entire youth was part of an elaborate plan to create the perfect super spy in director Geoffrey Sax's action-packed adaptation of author Anthony Horowitz's best-selling series of novels featuring an adolescent secret agent. Alex Rider (Alex Pettyfer) always though that his kindly uncle Ian (Ewan McGregor) was your average, everyday nondescript bank manager, but when Ian was murdered by notorious assassin Yassen Gregorovich (Damian Lewis), everything young Alex thought he knew would be forever changed by one simple bullet. A deadly martial artist, skilled linguist, steady-handed mountaineer, and deadeye marksman, Alex realizes that his uncle has been secretly training him in the art of espionage when he is recruited by MI6 Special Operations agents Mr. Blunt (Bill Nighy) and Mrs. Jones (Sophie Okonedo). It seems that billionaire Darius Sayle (Mickey Rourke) has generously offered to donate a complimentary Stormbreaker supercomputer to every school in Britain, but while his philanthropic offer is welcomed with open arms by the struggling school system, MI6 fears that something nefarious is afoot. Assigned the task of infiltrating Sayle's impenetrable lair by posing as the winner of a computer magazine contest, Alex makes the acquaintance of shady Sayle sidekicks Mr. Grin (Andy Serkis) and Nadia Vole (Missi Pyle) before getting a special sneak preview of the remarkable Stormbreaker's true powers. His cover subsequently blown, Alex is given a key piece of information regarding the remarkable computer before being thrown to a giant jellyfish by Sayle and his henchmen and left to die just as the prime minister is about to push the button that will activate Stormbreaker computers all across Britain. With no time to spare and the fate of a nation hanging in the balance, Alex must now enlist the help of his trusted housekeeper Jack Starbright (Alicia Silverstone) and faithful classmate Sabina Pleasure (Sarah Bolger) in ensuring that the Stormbreaker system is not activated and revealing Sayle for the true villain that he is before the young super spy's breathless first mission becomes his fatal last.
