Keira Knightley stars in this incredible true story of an Iraq War whistleblower who remains relatively little-known in the U.S. Katharine Gun was working for the communications office for the British government when she received a memo in the months leading to the war that showed that the U.S. requested illegal wiretapping assistance from the U.K. on U.N. diplomats. In a heroic act, she chooses to share this memo, hoping that it would stop her government (then led by Tony Blair) from going to war. Spoiler alert: didn’t happen, but this decision, which first seemed like a personal sacrifice, has severe implications on her family as the government finds out that she was behind the leak. A compelling political mystery of a case that deserves much more attention than it once got.
