Long before the Internet escaped from the lab, connecting the planet and redefining what it meant to meant to be a computer user... ...there was a brave and pioneering band of hobbyists who spent their time, money and sanity setting up their home computers and phone lines to welcome anyone who called. By using a modem, anyone who knew the phone number of these machines could connect to them, leave messages, play games, send and receive files in a virtual community... and millions did. They called these places "Bulletin Board Systems", or BBSes. Their collections of messages, rants thoughts and dreams became the way that an entire generation learned about being online.

DEFCON is the world's largest hacking conference, held in Las Vegas, Nevada. In 2012 it was held for the 20th time. The conference has strict no-filming policies, but for DEFCON 20, a documentary crew was allowed full access to the event. The film follows the four days of the conference, the events and people (attendees and staff), and covers history and philosophy behind DEFCON's success and unique experience.
