When SCUBA instructor, Chris Ducham, discovers the skeletal remains of a NAZI U-boat captain, along with Enigma encoded documents, in a cave on Barbuda, his curiosity gets the better of him. He decides to put his carefree life as a connoisseur of the easy life on hold to unravel the mystery. News of his discovery soon reaches the ears of a secret society, The Skull and Bones, who wish to keep a secret hidden. Chris soon finds his life in danger and what started as a simple adventure, quickly turns into a battle of wits with a brotherhood with unlimited resources. Indeed it seems that he is up against former Presidents of the United States of America and ruthless corporations. Rather than submit to intimidation, he seeks to uncover what secret could be of such importance that it is worth killing for. And why could such powerful adversaries not simple destroy it, rather than try to hide it?
