Watch Kuro no Tozoku

A group of adventure travelers goes to the heart of the Amazon jungle in South America during the month of May. This means that heavy rainfall and dangerous creatures are going to be a common part of their trek. The reason they are risking their lives is to find a hidden golden temple deep within the jungle known as Kai Ma. The troupe's leader - Jack Henry - is an all-out hardened soldier. He has experience in these parts, and when two of the group's members try to go back home, he decides to prevent them, causing the group to plunge into chaos.
