Rochefort, the Cardinal's right-hand man, announces the official disbanding of the King's Musketeers. Three, however, refuse to throw down their swords - Athos the fighter and drinker, Porthos the pirate and lover, and Aramis the priest and poet. Arriving in Paris to join the Musketeers, D'Artagnan uncovers the Cardinal's plans, and the four set out on a mission to protect King and Country.
The young D'Artagnan arrives in Paris with dreams of becoming a king's musketeer. He meets and quarrels with three men, Athos, Porthos, and Aramis, each of whom challenges him to a duel. D'Artagnan finds out they are musketeers and is invited to join them in their efforts to oppose Cardinal Richelieu, who wishes to increase his already considerable power over the king. D'Artagnan must also juggle affairs with the charming Constance Bonancieux and the passionate Lady De Winter, a secret agent for the cardinal.
