Part 1: Against All Odds - Joe Simpson's Crawl from Death on Siula Grande In 1985, mountaineer Joe Simpson shattered his leg during a descent from Peru's 20,813-foot Siula Grande.

This episode chronicles his extraordinary six-day crawl across glacier and rock with a catastrophically injured leg, no food, and minimal water.
