DEFCON, the globe’s premier hacking convention, takes place in Las Vegas, Nevada. In 2012, it celebrated its 20th edition. Although the conference typically enforces a strict no-filming rule, an exception was made for DEFCON 20, granting a documentary team complete access to the proceedings. The film captures the four-day event, showcasing the activities, participants, and organizers, while also delving into the history and philosophy that contribute to DEFCON’s distinctive appeal and success.
