D'Artagnan journeys to Paris expecting to be a musketeer, certainly one of those French king bodyguards, just to discover that the corps has been disbanded by conniving Cardinal Richelieu, who secretly expects to usurp the throne. Fortunately, Porthos, Athos and Aramis have refused to set down their weapons and continue to protect their king. D'Artagnan joins to expose Richelieu's plot from the crown.
