French Guyana, not so long ago. Eliott, a young and naive anthropology researcher, goes on an expedition to study the Otopis, a mysterious tribe from the Amazon rainforest.

Fortunately, Chantal, consumed by remorse and worried about her son, decides to abandon her own expedition and goes looking for him in the jungle, with the help of the not so helpful Lieutenant-Commander Raspailles and his men.
