Managing the plantation that supports a great many of the island population doesn't nearly fulfill the urges for adventure until his cousin, Hogshead Shaver, unexpectedly appears seeking help to recover his wife and child who have been kidnapped by the son of an old antagonist. Reluctantly setting out, his oldest son, Jean-Paul and best friend, Jeremiah, swim out to the departing ship to become members of the expedition. Re-united with his ship, The Raven, and many of the old crew, the Dolphin sets out to free Admiral Shaver's family intent on keeping his son from harm on an unforgiving ocean and from the battle he can not avoid.
