"The boulder hits my right arm and traps my hand against the side of the canyon. I am stuck and there's no way out."
Aron Ralston has always lived for adventure, but on a hiking trip in Utah, he has a serious accident. As he climbs across a canyon, a boulder falls and traps his right arm against the canyon wall. For six days, Aron is trapped. No one knows where he is and he has very little food or water. As time runs out, Aron has to make a terrible decision: to amputate his own arm.
