Horatio Nelson was Britain's greatest naval hero. He was famed for his dash-and-glory heroics. He was also a prolific letter writer. The letters reveal that Nelson was a very different and more complex man than the hero that Britain created after his death. Using Nelson's letters this drama documentary exposes Nelson's skilful and manipulative use of PR to advance his career, and shows how he was careful in his praise of his rivals - in case they threatened his own prospects. And the letters reveal how his passionate love affair with Emma Hamilton changed his life forever. Highly regarded RSC actor Jonathan Slinger portrays Nelson.
