Dr Forle is a scientist on a river station deep in the heart of the South American jungle: the last inhabited point before the impassable interior. He is studying the eerie forest glades that the local tribes call `devil`s gardens`. Who or what has created these cursed & poisoned places? The answer, he hopes, will change the way we think about life itself. But as The Devil`s Garden opens, work on the station is thrown into chaos by the arrival of a ruthless Colonel & a sinister Judge. They claim to be registering the indigenous peoples to vote & yet that night Forle witnesses an act of torture that he cannot ignore. From that moment on, he is drawn deeper & deeper into a world of brutality & corruption until he finds himself in the midst of a small war involving remote tribes, renegade soldiers, cocaine growers & the woman he has come to love. When one of his assistants is murdered, Forle is forced to abandon his life`s work & take sides. What kind of a man is he?
