Jeremy Corbell has spent years chasing the biggest secret in modern history, and it's cost him more than most people realize. He built his reputation filming the footage governments tried to keep hidden, from Navy warships tracking objects no one can explain to whistleblowers risking everything to speak up. Corbell talks about the years it took to earn a source's trust, the moment a supposed ally tried to steal his work in front of Congress, and what it's like knowing your phone might be tapped. He also opens up about his friendship with journalist George Knapp and the partnership that helped change how the public sees this whole story. This is the story behind the story, from the person who has been closest to it the longest.
