Ancient communities have lived for centuries in territories where nature sets the rules. Tropical forest, steep mountains, arid desert, unstable ocean or polar cold: these hostile environments shape ways of life based on adaptation and transmission. Into the Wild with Lucas takes us to meet communities who live in symbiosis with their environment, alongside Lucas Besse Dicaire, who shares their daily life up close. His journey reveals that it is possible to adapt to even the most hostile elements, to survive and to fully live without seeking to dominate nature.
