Slavery. A crime against humanity and basis for a whole economy in one of the most shameful aspects of our history is the backdrop against which Storm Warning is painted. Based on a true and all but forgotten incident, part sea chase and part courtroom drama, it is the story of the capture, trial and execution of Captain Nathanial Gordon, the only man in history to face conviction for slave trading, Commander Sylvanus Godon, who captured him at sea and those men who brought him to justice and fought in his defense in a landmark case that reaches from the Circuit Court of the Southern District of New York City all the way to Washington and the new President Lincoln.
