This documentary takes us to French Guiana to discover its rich biodiversity. On the other side of the Atlantic, this French territory is home to remarkable flora and fauna: cocoa trees and their pods, cecropia, sloths and, on the Salvation Islands, capuchin monkeys! Movie stars with their rich behavior, sophisticated gestures and incredibly similar skills to ours, these monkeys are fascinating. Great users of tools from nature, they live in small, very talkative societies in which the main game is to acquire power in order to climb the social ladder.
