A man of many adventures, Hugh Glass goes West in 1822 in the employ of Captain Andrew Henry to do some profitable fur trapping. He is attacked by a bear, and badly injured. Miraculously, he survives, but the terrain makes it impossible to carry him back. Henry tries, but eventually hires two mercenaries to simply stand watch and bury him. They abandon Glass, alone and defenseless, but unfortunately for them, he recovers. He resolves to hunt down the men who abandoned him.
