Based on the classic novel by Alexandre Dumas, this film is said to be one of the best adaptations. The legendary Three Musketeers are serving the King in Paris when the young ambitious D'Artagnan arrives, aspiring to join them. Scoffed at first, he proves he is worthy when he helps them single-handedly defeat eleven soldiers in a swordfight. They are then off to England to save the honor of their Queen and retrieve her famed diamond necklace from her secret lover, the Duke of Buckingham before the King finds out. Meanwhile, the evil Cardinal Richelieu is plotting to stop the Musketeers from fulfilling their mission.
