Since a 100 foot fall in 2002 that took his right leg and left him with spinal injuries, Colorado climber Craig DeMartino has led one hell of a life, including lauded First Disabled and In-A-Day Ascents on El Capitan. But his day-to-day life story is the one that should be making headlines.

What has four legs, five arms and three heads? The Gimp Monkeys. Craig DeMartino lost his leg after a 100-foot climbing fall. Pete Davis with born without an arm. Bone cancer claimed Jarem Frye's left leg at the age of 14. While the three are linked by what they are missing, it is their shared passion for climbing that pushed them towards an improbable goal - the first all-disabled ascent of Yosemite's iconic El Capitan.

In this film, two people and two worlds meet. Craig DeMartino, an adaptive climber from Boulder (Colorado) and Kai Lin, an industrial engineer from Brooklyn (New York) team up to design a game-changing prosthetic foot. This is easier said than done. Early prototypes don't hold up to the rigors of straight-in crack climbing, but this unlikely alliance is determined to test the power of problem-solving, so Craig and Lin keep at it.
