Professor Templeton gets more than she bargains for when she agrees to join an expedition whose goal is to find Genghis Khan's tomb. On her quest for his sarcophagus, she stumbles upon an ancient gold medallion. Its inscription enables her to uncover a conspiracy so horrific that not only does it create an international incident, but also causes one man to go insane and another to lose his life.
