D'Artagnan arrives in Paris at the tender age of 18, and that very day gives offence to three musketeers -- Porthos, Aramis, and Athos. Duels are agreed -- but interrupted by five of the Cardinal's guards. Instead of dueling, the four are attacked. D'Artagnan acquits himself impressively: his youthful courage becomes apparent during the battle. The four become friends, and, when asked by D'Artagnan's landlord to find his missing wife, embark upon an adventure that takes them across both France and England in order to thwart the plans of the Cardinal Richelieu. Along the way, they encounter a beautiful young spy, whom they know at first only as Milady, who will stop at nothing to disgrace Queen Anne of Austria before her husband, Louis XIII, and take revenge upon the musketeers.
