DEFCON, the hacker and cybersecurity conference held every year in Las Vegas, has kept film crews out for most of its two-decade run, wary of exposing attendees who guard their anonymity as carefully as their exploits. For DEFCON 20, the organizers finally let a crew in with full access for all four days, and the film follows that unusual permission rather than a scripted argument. Cameras move through talks, contests, and hallway conversations, catching staff and volunteers alongside first-timers and veterans who explain, on camera, why they keep coming back. The approach stays observational: no narrator supplying context, just badges, laptops, hallway deals, and the improvised feel of a conference that grew out of a small BBS gathering into the largest event of its kind. Interviews touch on DEFCON's internal culture and unwritten rules, including the norms around privacy that made this kind of filming rare in the first place. It plays as a record of one specific year rather than a full history, useful mainly for what the cameras were allowed to see.
