A day-by-day account of Aron Ralston's unforgettable survival story.

On Saturday, 26 April 2003, Aron Ralston, a 27-year-old outdoorsman and adventurer, set off for a day's hike in the Utah canyons. Eight miles from his truck, he found himself in the middle of a deep and remote canyon.

Then the unthinkable happened: a boulder shifted and snared his right arm against the canyon wall. He was trapped, facing dehydration, starvation, hallucinations and hypothermia as night-time temperatures plummeted. Five and a half days later, Aron Ralston finally came to the agonising conclusion that his only hope was to amputate his own arm and get himself to safety. Miraculously, he survived.

127 Hours is more than just an adventure story. It is a brave, honest and above all inspiring account of one man's valiant effort to survive, and is destined to take its place among adventure classics such as Touching the Void.
