On the Brink (2013)

Blood, Sweat, Tears, Agony, and Glory are just a few of the things athletes experience, and On The Brink is there to capture every moment. From Figure 8 Racing to MMA to Trampoline Dodgeball, athletes come from all different backgrounds, but the one thing they all have in common is that they all have a story. And those stories make these underground sports the most fascinating on the planet.
