In April 2003, mountaineer Aron Ralston goes hiking at Utah's Canyonlands National Park. He befriends hikers Kristi and Megan, and shows them an underground pool. After swimming, Aron parts ways with the hikers, and continues through a slot canyon in Blue John Canyon. While climbing, he slips and falls, knocking a boulder which crushes his right hand and wrist against the wall. He calls for help but realizes that he is alone.

Ralston begins recording a video diary to maintain morale as he chips away parts of the boulder to try and free himself and tries to keep warm at night. He rations his food and water to survive the ordeal. He sets up a pulley using his climbing rope in a futile attempt to lift the boulder.
