Bill Markham (Boothe) is an American engineer working on a dam project in the Brazilian jungle which threatens the existence of the Indian tribes living there. When his seven-year-old son is abducted by a tribe, Markham begins a tireless ten-year search to discover his whereabouts. When he finally tracks him down, he finds his little boy has grown into a fully fledged and much accepted member of the tribe. How can he persuade him to return to civilisation?
Returning to some of the themes which informed the superior "Deliverance" (1972) (the interaction between town and country, the effects of global expansion on tribal cultures, the fragile interaction between man and nature), Boorman, ever the visionary, conjured something of a return to form. There's no denying the film's conviction and intelligence and if it sometimes overplays the connection between the Indians and mother nature, it at least avoids the heavy-handed, didactic tone synonymous with other chronicles of capitalist greed.
On another level, it's also a rattling good adventure yarn, scintillatingly shot by the venerable Philippe Rousselot and acted with conviction by Boothe and a cast of indigenous Indians, whose subtitled dialect furthers the film's authenticity.
