Once an outpost for gas exploration, the abandoned site now houses a multinational research team. They are driven by an ambition to penetrate further into the Earth's crust than anyone before. What awaits him amidst the howling winds and shifting sands remains shrouded in ominous mystery, a secret buried deep within the heart of the desert.
