127 hours is movie based on the real story of an engineer Aron Ralston, who will have a hobby of climbing the mountains.
Aron alone bikes to a canyon. Although he meets couple of girls in the canyon he will continue his mountaineering once they leave him. Aron accidentally falls while climbing and his hands get struck in between two rocks. Aron tries his best to take off his injured hand. But, all his efforts go in vain. He spends more than 5 days alone in the canyon in between rocks hoping somebody would help in. With very little water and no food, his struggles for survival. Finally he makes a fatal decision to cut his hand from a dull knife. But he struggles to cut his bone. So, he twists his hand to cut break the bone and cuts the hand. He then walks several miles to go out of canyon. He finally meets few family who will help him by providing water and he will be evacuated with the helicopter.
Overall its a very good movie to watch. Director had tried to best to deliver the Aron has gone through during those 127 hours.
