Your arm is trapped. You're miles away from civilisation. You've gone 5 days without food, water or shelter. All you have is a pocket knife and a will to live . . .
On Saturday, 26 April 2003, Aron Ralston, a 27-year-old outdoors man, 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 he was not going to be found. He then made the most difficult decision of his life: to amputate his own arm and get himself to safety. Miraculously, he survived . . .
How far would you go . . .
