On summer vacation from grad school, Shelley Hanover takes part in a modern-day treasure hunt on a newly discovered Spanish galleon off the Florida Keys. During the dive, Shelley finds a silver bangle, and when the clasp opens, she is swept into a sudden water vortex — and into the arms of a sexy-as-sin pirate.

Captain Jason Flint finds a woman floating in the wreckage of his latest victory, strangely dressed and wearing a sex-slave band. He decides to keep her as his private pleasure captive, and they enjoy each other's hot flesh as they sail the cool Caribbean waters. But when a rival captain kidnaps Shelley, Jason realizes he's lost something greater than any pirate treasure.
