Tribes on the Edge follows Céline Cousteau as she returns to the Brazilian Amazon after a fateful email from Beto of the Marúbo tribe beckons her back to help tell his people's story. Céline ventures into the heart of the jungle to explore the health crises and the threats to land and human rights of the Indigenous Peoples of the Vale do Javari, expanding the view to how this is relevant to our own lives. From a history of invaders bringing devastating diseases all the more relevant in our current global pandemic, to the ongoing illegal activities such as hunting, gold mining and deforestation, to the alarming dismantling of all protection of their land and human rights by the government. More than a narrative of tribal reality in the Amazon, the film provides a perspective on how our future is interwoven with theirs and with nature. The indigenous communities are fighting to protect their home, critical to the ecological balance of our planet, and as a result...they protect us.
