The Mongolian Border, 1979: Massive fossils of unknown creatures are discovered in the mountains, and the research team assigned to excavate the remains includes acclaimed Professor Yang (Wang Qingxiang), Hu Bayi (Mark Chao), and Ping (Yao Chen), the professor's beautiful daughter. When a freak explosion triggers a rockslide, only a handful of explorers survive the fall to the mountain's floor... unearthing an ancient temple and the hideous creatures waiting within. Now living a quiet but tormented life as a librarian, Hu studies demonology manuscripts, seeking answers for that fateful day.
