Since pre-Columbian days, the indigenous Colombian tribe known as the Kogi has thrived in isolation in the Sierra Nevada de Santa Marta range. In 1990, their priests made a rare foray into the outside world to entreat for an end to the squandering of the planet's resources. Now, they have emerged again for a second─and perhaps final─warning to us to change for the better. 86 min. Widescreen; Soundtrack: English.
