The Superdeep (Blu ray)
The Kola Superdeep borehole is the largest Russian secret facility. In 1984, at the depth of more than 7 miles 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 go down below the surface to find the secret hidden these many decades. What they discover will pose the greatest threat humanity has ever faced.
