Rocky Mountains, 1823. When a scouting mission puts Hugh Glass face-to-face with a grizzly bear, he is viciously mauled and not expected to survive. Two men from the company are ordered to remain with him, but, fearing an imminent attack, they abandon Glass, stripping him of his prized rifle and hatchet. With shocking grit and determination, Glass sets out on a three-thousand-mile journey to seek revenge on the men who betrayed him.
