Deep in the Amazon, on the border of Brazil and Colombia, a series of bizarre deaths are investigated by a young female detective, Helena, and her partner, an indigenous policeman named Reynaldo. It becomes clear that the murders are not the biggest mystery within this jungle when the corpse of a particular young woman has no signs of aging. Simultaneously, we follow the story of Yua, and Ushe, two natives who everyone calls “the eternals”, and their battle against Joseph, a foreigner who believes the indigenous population is harboring an incredible secret. The stories and characters will collide to unravel a mystery that can change their lives, and the whole of mankind.

The air is thick with tension as a military squad proceeds to the foot of a mountain base, where they’re ordered to wait for backup and hold their position. The mountain is shrouded in fog and the men are exhausted. They’ve been fighting guerrillas on enemy turf for some time, and they’re worn down by the stress and anxiety of battle. The men don’t want to wait; they want to charge up the hill, fearing that their comrades in the base have been overrun by the guerrillas. The squad’s leader tries futilely to keep his men in line while dealing with his insolent second-in-command.
