It's 1802. The Treaty of Amiens has brought an end to the hostilities between Great Britain and France. Captain Jack Aubrey and his friend, naval surgeon Stephen Maturin, are enjoying the respite in the English countryside, besotted with two beautiful cousins, Sophie Williams and Diana Villiers -- until Aubrey loses his fortune and they flee to France to escape his creditors. While in France, Napoleon smashes the Peace of Amiens and war begins anew. Aubrey and Maturin, now finding themselves behind enemy lines, make their way back to England. Maturin is sent to Spain on an intelligence-gathering mission and the now-solvent Aubrey assumes command of a strange warship, pursuing his quarry straight into the mouth of a French-held harbor. Amidst the rollicking adventures at sea and mishaps on land, Aubrey and Maturin's friendship is tested by their romantic entanglements with the cousins.
