David's pirate ancestor, the Dolphin, caused the sinking of a Spanish treasure ship off the coast of southern Cuba. Now a Ph.D. Archaeologist, David is ready to recover the treasure which he believes is significantly more valuable than the gold, silver, and jewels undoubtedly aboard. Now married to Concepción, they have a boy who becomes the delight of an old Haitian lady where they base their operations. Not only does David have to contend with the Boggues cartel, but also an antagonistic Cuban government official who attempts to interfere. What David discovers is beyond his wildest dreams—both underwater and about his son.
