In January 2013, Laura Poitras was making a film about international surveillance when she started receiving encrypted emails from “citizen four,” a source who wanted to blow the whistle on the NSA’s covert surveillance programs. In June 2013, she packed her camera and traveled with journalist Glenn Greenwald to Hong Kong, where they met Edward Snowden. The documentary resulting from this tense encounter is a real-life thriller. Poitras compresses days of questioning, waiting, and watching the world’s reaction into a masterful film that combines an intimate character study with a gripping plot that hurtles toward an explosive conclusion.
