Five years ago, director Alex Gibney set out to make a documentary about the miraculous, superhuman comeback of Lance Armstrong. The world's most famous cyclist had made two competitive comebacks to the sport after his struggle with cancer and reemergence from retirement.

But by the time the film was complete in 2013, Armstrong had admitted to using performance-enhancing drugs in the shadow of federal criminal investigations by the U.S. Anti-Doping Agency and the International Cycling Union. Instead of a behind-the-scenes look at a miraculous human, The Armstrong Lie chronicles the rewriting of history surrounding one iconic man—and gives us a glimpse into unprecedented scandal. During the filming of the movie, Gibney found himself with one-of-a-kind access and an insider’s look at what happens when one of the world’s top athletes falls from grace.

As Armstrong tells Gibney’s camera: “I didn’t live a lot of lies, but I lived one big one.”
