LaBarge, regional superintendent in Gascony, is arrested for killing two musketeers. Our friends are tasked to bring him safely to Paris. The Red Guards, who are tired of the Musketeers' treatment of LaBarge, provoke a confrontation between the two regiments. King Louis, who is tired of this rivalry, is organizing a competition to determine once and for all which of the two regiments is strongest. D'Artagnan takes on the challenge - but needs to work on himself that his temper should not go to his head - to show that he mastered the art of battle.
