Six years after the French Revolution, when the country was drowning in bloodshed due to the struggle of all sorts of political parties—and people were dying of hunger right in the streets—young royalists led by the Duke de Montescq, driven by a good goal: to restore power to the king, set off to search for the treasures of the famous courtesan, Madame Du Barry, who had been executed.

But at the same time, a gang of robbers tries to find the cache too, led by the mysterious Sharpen-er, and no one knows who will reach the cherished goal first.
