The Battle of Brimstone Hill in 1782 discloses a once secret clandestine ocean escape route for the embattled fortress. British troops holding the fort make a danger-filled dash to remove their treasure from the hands of the invading French. More than 230 years later, this long forgotten underground hideaway is now inhabited by modern day pirates. The Caribbean Sea becomes the backdrop of an impending mass murder and theft, the size of which will stagger the world. Vacationing after their ordeal in the Amazon, Dane Skoglund and Hugo Winsor along with their cohorts stumble across the deadly plans and are drawn unwillingly into the fray. This sinister plot begins in the dusty Middle East and spreads to the beautiful islands of St. Maarten and St. Kitts. Their vacation becomes a nightmare, threatening the lives of Dane, Hugo and their party, forcing them into action to save their friends and thwart pirates trying to orchestrate the largest theft in history.
