The Four Musketeers defend the queen and her dressmaker from Cardinal Richelieu and Milady de Winter.

D’Artagnan, on a quest to rescue the abducted Constance, runs into the mysterious Milady de Winter again. The tension between the Catholics and the Protestants finally escalates, as the king declares war — forcing the now four musketeers into battle. But as the war goes on, they are tested physically, mentally and emotionally.

At the behest of his father, young d’Artagnan travels from rural Gascony to Paris, where he becomes embroiled in a devious plot between the King’s Musketeers and the Guardsmen of Cardinal Richelieu.
