In 1494, under the eyes of the King of France Charles VIII and the Duchess Blanche of Savoy, Captain Bellabre is ridiculed during a tournament by a young unknown, Pierre Terrail. In order to take revenge and divert him from his impossible love for the beautiful Duchess Blanche, Bellabre decided to take him under his thumb and to let her know the harsh realities of the war during the Italian campaign. But it will be gradually supplanted by the prowess of its protégé who will become the famous knight, Chevalier de Bayard. He then decides to devote himself entirely to the glory of the future "knight without fear and beyond reproach".
