When an American oil company sets up an experimental drilling plant out in the vast deserts of Mongolia, they are completely oblivious to what actually lies beneath them. Pumping hot water deep into the ground, the company is hoping to expose untapped oil, but what they end up uncovering is something no one ever expected. As the superheated water plummets it's way into the earth, it strikes a nest of deadly creatures that have been dormant for centuries. Thought to be purely mythological, these monsters are in fact real and now they have been awakened! They are angry and they are bloodthirsty. They are known as the MONGOLIAN DEATH WORMS.
