His cases delve into the dark corners of the world, searching for truth in the occult remnants of ancient civilizations. Now, the greatest mystery of his past is about to become the most dangerous case he has ever faced. With the help of his ex-flame, archeologist Aline Cedrac (Tara Reid), and his bitter rival, government agent Richard Burke (Stephen Dorff), Edward Carnby is about to learn that just because you don�t believe in something, that doesn�t mean it can�t kill you.
