Last Survivor of an Unknown Amazon Tribe
A 16-year-long record of an isolated Amazon tribe in Brazil, uncontacted by the civilized society-- which is called "Isolado." 30 years ago, Brazilian authorities protected two naked men who appeared from thick forest all at once. Their language was completely unknown. As one of them has already died, this one tribe will disappear before very long. What happened to the tribe and left the two men all alone, is still shrouded in mystery.
