The British are having a difficult time in the Caribbean. Some of the islands are in open revolt and the Governor has been killed by his own brother. Anarchy rules and a cruel and bloodthirsty gang of pirates and gaolbirds are free to do as they want, burning and looting the houses of the wealthy merchants and plundering at will.
Susan Nelson, the Governorís daughter, is caught up in the growing lawlessness whilst visiting one of the outlying islands. Unaware of her fatherís death, she conceals her and sets out to return to the capital, Port Kingston.
The girl tries to escape in a small boat but is captured by pirates.
By a cruel twist of destiny she is purchased in a slave market by her detestable Uncle George, now head of the uprising against the Governor.
