I Shouldnt Be Alive (2005)

Twenty five year old nurse Linda Forney and her pet dog Cocoa Gin set off to explore one of the seven natural wonders of the world - the Grand Canyon. On route to a native Indian village she takes a wrong turn and ends up lost, alone and with no food or water. Totally disoriented Linda hikes deeper into the maze of sub-canyons that make up the Grand Canyon. With temperatures exceeding 100 degrees and surrounded by exotic and dangerous wild animals, Linda finds herself in a real fight for survival. After weeks of little water, dehydration and starvation start bring her close to death. Then she finds herself trapped in a canyon, with no way out.
