One of our co-workers recommended this:

Based on the true story of Hugh Glass – adventurer, pirate, frontiersman – Punke explores this amazing tale of survival. In 1822 Glass signs on as a trapper with Captain Andrew Henry. During their trip he is mauled by a grizzly bear:

His throat nearly ripped out, scalp hanging loose and deep slashing wounds to his back, shoulder and thigh, Glass appears to be mortally wounded. Initially, Captain Henry refuses to abandon him and has him carried along the Grand River. Unfortunately, the terrain soon makes transporting Glass impossible. Even though his death seems certain, Henry details two men, a fugitive mercenary, John Fitzgerald, and young Jim Bridger (who lived to become a frontier hero) to stand watch and bury him. After several days, Fitzgerald sights hostile Indians. Taking Glass’s rifle and tossing Bridger his knife, Fitzgerald flees with Bridger, leaving Glass. Enraged at being left alone and defenseless, Glass survives against all odds and embarks on a 3,000-mile-long vengeful pursuit of his ignominious betrayers. – PW
