Citizenfour

In 2013, when the director was filming a film about U.S. intelligence surveillance after the September 11 attacks, one day she received an anonymous email signed "Citizen Four" reminding her that she was on the NSA surveillance blacklist. A few months later, she and "Guardian" reporter Glenn Greenwald went to Hong Kong to meet "Citizen Four", and then came the "Snowden incident" that shocked the world! The film intimately records Snowden's mental journey since joining the National Security Agency and the shocking truths he learned.
