The Amazon is the biggest river on Earth. Only little of plant and animal life along its banks is known to man. And there are many secrets known to the tribe shamans of which we never heard. During a journey of one of those shamans down the river from one of its wells, who meets a western scientist traveling up the river from the sea, the audience experiences a huge variety of landscapes, animals (pink dolphins, for example), plants and people.

Narrated by Geoffrey Holden and filmed in Australia, Costa Rica, French Guiana, and Malaysia. The film captures the incredible diversity of species which have evolved throughout the long history of tropical biology-insects, gaudy frogs, exotic plants and flowers.
