A sequel to the 1973 adaptation of The Three Musketeers, The Four Musketeers covers the second half of Dumas' classic novel. Cardinal Richelieu (Charlton Heston) has another evil plot, this time ordering the kidnap of Constance de Bonancieux (Racquel Welch), dressmaker of the Queen of France. The Musketeers must help Constance and the Queen, and protect them from the Cardinal, and his spy, Milady de Winter (Faye Dunaway).
