Between the 40's and 70's, the public health physician Noel Nutels travelled around inland Brazil providing medical care to indigenous, rural and riverside populations. Noel filmed many of his expeditions on 16mm film. In 1968 he was invited to speak on the indian situation at a parliamentary inquiry commission, a few days before the radicalization of the dictatorship in Brazil. His unpublished films and the record of his speech at the commission come together in "The Pink Indian Against the Invisible Beast" to denounce what Nutels called the historic massacre against indigenous people.
