Outdoor adventurist Aron Ralston believes he's invincible and can do it all alone while on his outdoor adventures. He considers the great outdoors his second home. On Saturday, April 26, 2003, Aron has gone for an adventure trek alone through the generally secluded Blue John Canyon, and like he has done on many of his other treks, he has not told anyone where he is going. But on this day, he and a small boulder fall down a crevice, he landing near the bottom of the crevice virtually unharmed, but with his right hand wedged between the boulder and the crevice wall. He has access to his gear and his small supply of rations as he tries to move the boulder or chip away at it so that he can get his wedged hand free. As either task seems impossible, he hopes for someone to rescue him. Those most likely candidates are Kristi and Megan, two women he met earlier that day who are the only two who know that he is in the canyon, or his boss Brion, who may list him as missing if he doesn't show up for his scheduled work time on Tuesday (three days away). As time goes on and he deals not only with the boulder and lack of rations but also with the extreme weather conditions, he begins to think about his mortality, his mind often going toward his loving but somewhat distant relationship with his family, or his last broken love with a woman named Rana. As he films himself (as a goodbye message to his family) often with his mind wandering, he, during his more lucid moments, also thinks about the possibility of trying to sever his arm as he will lose it anyway if he survives this ordeal.
