The Emerald Forest

An American engineer (Powers Boothe) takes his family to the Amazon Basin to build a major dam, but his son suddenly disappears and there are rumors that he may have been taken by a tribe called The Invisible People. Ten years pass and he’s still looking. Will he find him? Will the son (Charley Boorman), now a grown tribesman who has become one of the Invisible People, recognize him and challenge Bill Markham's idea of true civilization?
