Kick-box champion David Sloan arrives in Rio de Janeiro for an exhibition fight. He and mentor Xian take pity on Brazilian rascal Marcos Coasta, an urchin who offers guide services but routinely steals from tourists for himself and his older sister Isabella. David is shocked when he sees how his Argentinian opponent Marcelo needlessly abuses a courteous local sparing partner. That’s the doing of his evil US manager, Lane. He has nasty plans to force David to cheat and runs a white slavery racket.

For ten years, engineer Bill Markham has searched tirelessly for his son Tommy who disappeared from the edge of the Brazilian rainforest. Miraculously, he finds the boy living among the reclusive Amazon tribe who adopted him. And that’s when Bill’s adventure truly begins. For his son is now a grown tribesman who moves skillfully through this beautiful-but-dangerous terrain, fearful only of those who would exploit it. And as Bill attempts to “rescue” him from the savagery of the untamed jungle, Tommy challenges Bill’s idea of true civilization and his notions about who needs rescuing.
