Ishi's Return (2016)

The story of Ishi, who became known as the "last wild Indian" when, at about 50 years of age, he wandered out of the woods in Oroville, Cal., in 1911. He died five years later; and his brain was sent to the Smithsonian Institution in Washington, D.C.. Eighty years later, however, his descendants successfully fought to have his remains repatriated to his ancestral home.
