At Sword's Point

After the death of Cardinal Richelieu, the aging Queen of France (Gladys Cooper) struggles against her archrival, the Duke of Lavalle (Robert Douglas). Seeking to protect Princess Henriette (Nancy Gates) and her son from Lavalle's plots, the queen summons the former Musketeers for aid. Old and retired, the guards send their sons, juniors D'Artagnan (Cornel Wilde), Porthos (Alan Hale Jr. ) and Aramis (Dan O'Herlihy), in their places -- while Athos sends his daughter, Claire (Maureen O'Hara).
