The Kola Superdeep borehole is the largest Russian secret facility. In 1984, at the depth of more than 12 kilometers below the surface, unexplained sounds were recorded, resembling the screams and moans of numerous people. Since these events, the object has been closed. A small research team of scientists and military personnel had gone down below the surface to find out the secret that the world's deepest borehole was hiding. What they have found poses the greatest threat that humanity has ever faced. Now the future of the world is in their hands.
