Deep in the jungles of Peru, a journey through the centuries begins. Journey to the legendary Inca idol. An idol carved from a strange stone, which at the end of the 20th century could become the basis for the creation of a terrible weapon. The US Army wants to get this idol at any cost, but not only them... Only in a 400-year-old manuscript is the key to the whereabouts of the idol. William Race, a young linguist invited to translate the manuscript, is forced to lead a US Army detachment on a quest to retrieve the idol. Thus begins the mission. A mission that will lead Race and his team to a mystical stone temple hidden at the base of the AED. A temple around which even the air is saturated with horror and danger. But only after opening the doors of the temple, Reis and his companions will understand that they have violated the golden rule: Some doors are better left closed...
