Alex Honnold has become known as the boldest soloist of his generation. In this dangerous game, how does he balance pure ambition with self-preservation? From highball boulder first ascents to 5.13 free solos, from far-flung trad climbing adventures, to speed records on The Nose, Honnold wrestles with this question in preparation for his biggest adventure yet - the Yosemite Triple. In under 19 hours he climbs Mt. Watkins, El Cap, and Half Dome, 95% of it free solo.
