American climbing dirtbag Andy Lewis is taking the discipline of slacklining into the future as he solos the worlds longest high-lines and masters the hardest aerial tricks, all the while pushing his equipment to the limit. As Andy goes higher, harder and faster with climbing, slack and BASE, we all hsve to wonder how far he can go before it's one step over the line.

At British Columbia's spectacular Helmcken Falls, a revolution is taking place, led by Canadian maniac Will Gadd. After 30+ years of ice climbing, Gadd has finally realized his dream of climbing radically overhanging, heinously difficult ice. Gadd and Tim Emmett dodge exploding 30 foot icicle bombs and send the hardest pure ice climb in the world, but they swear it's just the first step in a whole new direction for the sport.

Tommy Caldwell is the master of big wall free climbing. He's devoted the last decade of his life to opening free routes on Yosemite's El Capitan, rewriting climbing history in the process. Now he's three seasons deep into his ultimate project - the seemingly impossible Dawn Wall.

Over the past 26 years, 16 expeditions have tried and failed to climb one of Pakistan's 8,000 meter peaks in winter. In February 2011, Simone Moro, Denis Urubko, and Corey Richards became the first to achieve this alpine dream by summiting Gasherbrum II, surviving -50 degree temperatures and a massive avalanche. Richards captured both the glory and the pain of their adventure in this raw and moving, first-person look at modern super-alpinism.
