This gripping political thriller tells the real life story of a government whistleblower who exposed the unlawful basis for the 2003 Iraq War. Katharine Gun (Keira Knightley) is working at GCHQ, watching Tony Blair justify the invasion on evidence she knows is faulty. When America's NSA ask her and her colleagues to blackmail UN security council members to force a resolution for war, she is put in an untenable moral dilemma.
Keira Knightley continues to confirm herself as one of the UK's top actors, giving a richly conflicted portrait of this neglected but crucial historical figure. Gavin Hood follows Eye in the Sky with another compelling thriller that brings out the drama from the real life events.
