Man Called Horse, A (Richard Harris)

English aristocrat John Morgan is captured, enslaved, and treated like an animal by a Native American tribe. He comes to respect his captors' culture and gain their respect. He is aided in understanding the Sioux by another captive, Batise, the tribe's half-breed fool, who had tried to escape and was hamstrung behind both knees.

Determining that his only chance of freedom is to gain the respect of the tribe, he overcomes his repugnance and kills two warriors from the neighboring enemy Shoshone tribe, which allows him to claim warrior status. After his victory, he proposes marriage to one of the women with the horses taken in battle as bride-price and undergoes painful initiation rites, taking the native name "Shunkawakan" (or "Horse") as his Sioux name.
