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.
