A tale of resilience, grit, and elite rescue volunteers going out of their way to save the lives of strangers, 109° BELOW traces how an attempted rescue on Mount Washington in 1982 changed not only the course of two climbers’ lives – but also the lives of the rescuers who tried to save them, and the future of prosthetics, forever. Featuring: Hugh Herr, Joe Lentini, and Alexa Siegel
