The legend of Yamashita's Gold lures a treasure hunter and his group deep into the Indonesian jungle. Once they are trapped in an abandoned World War II Japanese bunker, they face the terrifying reality that the only way out is to go further in.

On an isolated island in Indonesia, an expedition is apparently seeking the legendary Yamashita's Gold. Out of the blue, they are attacked and seek refugee in an abandoned Japanese bunker. Soon they discover that the place was a secret laboratory during World War II where the prisoners were guinea pigs in weird experiments. Further, they are trapped inside with strong and resistant creatures created by these experiments. Will they succeed in escaping from the dead mine?—Claudio Carvalho, Rio de Janeiro, Brazil
