Two men from opposite sides of the world must work together to explain the unexplainable.

• A wealthy businessman accused of spilling toxic waste into the ocean is discovered dead in his office. Although the room is completely dry, he is believed to have drowned.
  
  
• A beautiful mistress of a government official has been burned to death in her home, although there are no signs of fire anywhere.
  
  
• A priest known for transporting illegal weapons is found in his bed, disemboweled, although there are no signs of struggle.

To solve these grisly crimes, the Taiwanese government is forced to enlist the help of an American FBI agent (David Morse, "The Green Mile", "Dancer In The Dark"). He is teamed with a troubled local cop (Tony Leung, "The Lover") and together they must do the impossible. Their journey will lead them into Taiwan's darkest corners and to an ancient cult in search of immortality.
