What techniques can the average person use to survive a life-or-death confrontation? To examine methods of turning victims into victors, a team of self-defense experts employ a variety of advanced biomechanical sensors, high-speed photography and 3D animation in the custom-designed lab. You'll see how experts predict an attack before it happens, and how they prevail in a fight even when they are outmatched applying force to vulnerable points on an assailant's body.
