United States of Secrets

When NSA contractor Edward Snowden downloaded tens of thousands of top-secret documents from a highly secure government network, it led to the largest leak of classified information in history — and sparked a fierce debate over privacy, technology and democracy in the post-9/11 world.

Now, in United States of Secrets, FRONTLINE goes behind the headlines to reveal the dramatic inside story of how the U.S. government came to monitor and collect the communications of millions of people around the world—including ordinary Americans—and the lengths they went to trying to hide the massive surveillance program from the public.

In part one, a two-hour film premiering Tuesday, May 13 at a special time (9 p.m.), FRONTLINE went inside Washington and the National Security Agency, piecing together the secret history of the unprecedented surveillance program that began in the wake of September 11 and continues today – even after the revelations of its existence by Edward Snowden.

Now, in part two, premiering Tuesday, May 20 at 10 p.m., veteran FRONTLINE filmmaker Martin Smith (The Untouchables, To Catch a Trader) continues the story, exploring the secret relationship between Silicon Valley and the National Security Agency, and investigating how the government and tech companies have worked together to gather and warehouse your data.
