While guiding a group of fur trappers across the hostile native-laden Dakotas during a brutal early 19th-century winter, frontiersman Hugh Glass (Best Actor Oscar-winner Leonardo DiCaprio) is mauled within an inch of his life by a bear. When his impatient party elects to push on and leave him to die, he musters the will to live...and embark on a seemingly impossible 200-mile trek in search of vengeance against those who abandoned him.
