"CITIZENFOUR is a real life thriller, unfolding by the minute, giving audiences unprecedented access to filmmaker Laura Poitras and journalist Glenn Greenwald’s encounters with Edward Snowden in Hong Kong, as he hands over classified documents providing evidence of mass indiscriminate and illegal invasions of privacy by the National Security Agency (NSA).
On July 2nd, 2013, after attending the Gas Exporting Countries Forum (GECF) conference, Bolivian President Evo Morales departed Russia from Vnukovo Airport in Moscow aboard his presidential plane. However, a "leak" suggested that Edward Snowden was aboard, which led Spain, France, and Portugal to close their airspace to the aircraft, to then be grounded in Austria.
