During the Cold War, the United States developed a massive surveillance system called PROJECT 415, now known as ECHELON. Today the Cold War is over, but these giant ears placed in all four corners of the world are still being used'.

Juicy, entertaining and densely informative, The Secret Power demonstrates the extent to which private communications are illegally and constantly spied on by Echelon, which spans the globe, plumbs the ocean depths and beams into outer space and back. Visually and intellectually lively, this film, designed to mimic an espionage thriller, is a riveting, spine-tingling account of five sneaky English-speaking nations working in collusion. - Variety
