In his mission to better understand the last nomadic peoples, explorer and neuropsychologist Guillaume Dulude travels to the center of Sumatra Island, Indonesia, to meet the Orang Rimba. Their name means “Men of the Jungle”. The tribe lives among the forest, for the forest, and in symbiosis with the forest. Their gods are linked to it, as well as their subsistence and their way of life. However, modernity and its pitfalls are catching up with them and threatening their survival. For several years, the palm oil trade has been responsible for the deforestation of this part of Indonesia. This oil, nicknamed “red gold”, is the most sold in the world and pushes the Orang Rimba to the limit.
