Knights of Mayhem (2011)

Led by reigning world champion Charlie Andrews, these guys are made of "hard steel and sex appeal," weighing in at over 200lbs each. They've dedicated their lives to the sport and seeing it through to the professional arena. Leaving their families and fear behind, the knights are tested both emotionally and physically. The impact of battle brings risks of broken bones, concussions, collapsed lungs, broken ribs or even life in a wheelchair.
