Sharpe's Honour (1994)

Spain, 1813. Sharpe is unwittingly caught up in a French plot; he is convicted of the murder of a Spanish nobleman and sentenced to death.

In a desperate attempt to clear his name, Sharpe is forced to venture deep into enemy territory to capture La Marquesa, a beautiful French spy, who alone can prove his innocence.
