Aluna is made by and with the KOGI, a genuine lost civilization hidden on an isolated triangular pyramid mountain in the Sierra Nevada de Santa Marta, Colombia, nearly five miles high, on the Colombian-Caribbean coast. A sequel to the BBC documentary "TheHeart of The World: Elder Brother's Warning" (1990), the Kogi tribe (calling themselves Elder Brother) once again re-emerge to express their concern for the state of the modern world Younger Brother. This time, the Kogi offer their secret sciences inthe belief of sharing the burden for global change. So begins a truly bizarre journey. Without wheels or a written-language, the Kogi are able to seriously discussing dark energy with a leading astronomer and correctly identifying objects seen by the Hubble telescope. Though the Kogi suspect the filmmaker doesn't comprehend their messages, they reveal an unquestionably apocalyptic horror.
