She risked everything to stop an unjust war. Her government called her a traitor. Based on world-shaking true events, Official Secrets tells the gripping story of Katharine Gun (Keira Knightley), a British intelligence specialist whose job involves routine handling of classified information. One day in 2003, in the lead up to the Iraq War, Gun receives a memo from the NSA with a shocking directive: the US is enlisting Britain’s help in collecting compromising information on UN Security Council members in order to blackmail them into voting in favor of an invasion of Iraq. Unable to watch the world be rushed into an illegal war, Gun makes the gut-wrenching decision to defy her government and leak the memo to the press. So begins an explosive chain of events that will ignite an international firestorm, expose a vast political conspiracy, and put Gun and her family directly in harm’s way.
