False accusations of adultery propel Sharpe into a duel over a woman he has never even met. Duels are forbidden in Wellington's army, and it is only the wily Major Nairn that keeps Sharpe from a court martial. However, when Sharpe's Spanish opponent is murdered in cold blood, even Nairn can't save him. A trial is held, and Sharpe is condemned to hang. Sharpe's Honour is the fifth TV movie based on the Sharpe series, and was filmed in 1994.
