The Emerald Forest is based on a true story, as related by Los Angeles Times correspondent Leonard Greenwood. Powers Boothe stars as Bill Markham, a US engineer working on a dam project in the Amazonian jungles. Bill's young son, Tomme (played by director John Boorman's son Charley Boorman) is kidnapped in the rain forest by a tribe called The Invisible People because of their skills at camouflage - a group that has reportedly never experienced contact with Caucasians. The authorities give up the boy for lost, but Bill perseveres in searching for his son, for over 10 years. While fleeing for his life from The Fierce People - enemies of The Invisible People - he's rescued at the last minute by Tomme, now an adoptee of The Invisible People's chief. To Bill's frustration, Tomme initially refuses to join his biological dad and return to civilization, but when The Fierce People swing in and abduct all of the women in the Invisible People tribe, Tomme seeks his dad's help in rescuing them.~ Hal Erickson, All Movie Guide
