'Secrets of the Tribe' gaat over de antropologen die jaren geleden de Yanomami indianen ‘ontdekten’ en ‘gebruikten’ voor hun onderzoek. Padilha neemt in zijn film de antropoloog en zijn vak onder de loep. Gedurende de film wordt op pijnlijke wijze duidelijk dat het niet altijd goedbedoelde onderzoeken zijn die zij uitvoeren. Schandalen worden ontbloot; pedofilie, ziekteverspreiding en atoomproef werkgroepen komen aan het licht.
Ja! de film Segredos da Tribo is nu beschikbaar om te kijken op Netflix in Nederland.
