The impressive evolutionary history of the jungle is told in locations in Peru, Gabon and France. Documentary filmmaker and Oscar winner Luc Jacquet delves into the depths of the tropical jungle and explores the prehistoric rainforest. Acting in front of the camera is botanist and ecologist Francis Hallé. A luminary in the field of biology, he studied the interaction of plants and animals for many years. Jacquet and Hallé apply this knowledge here in an exemplary manner and explain the life cycle of the forest in a vivid way.
