An evil corporation led by Brian Dennehy bulldozes its way through an Amazonian village which just so happens to be the home of returning half breed ex-marine, Francesco Quinn.
Deploying an impressive, MacGyver-esque assortment of booby traps, Quinn naturally enough declares a one man war against a bunch of bad guys who have just recently driven a big JCB over his tribe chief dad.
The resultant, proto-Avatar Eco-blabber, grafted onto a plain-for-all-to-see Rambo-style revenge premise, is just about palatable. Marvelous Marvin Hagler's wooden performance, however, in a superfluous role as the drill instructor who trained Quinn, hired by the corporation to do away with him but nonetheless sympathetic to his plight, is pretty hard to swallow.
Dennehy's ability to hang on to his New York Yankees baseball cap despite being flung out of a chopper and into a boggy ditch is commendable, as is Margheriti's handling of several well executed action sequences. They're enough to ensure Indio remains an enjoyable, though typically derivative example of the Italian Jungle excursions.
