Q:Build a movie plot around this: Does Buckingham help the rebels? No, he gets murdered.
A:
(Sequel to The Three Musketeers)Porthos (Frank Finlay) recaps the events leading to D'Artagnan (Michael York) becoming a musketeer. The original trio, including Porthos' companions Aramis (Richard Chamberlain) and Athos (Oliver Reed) find themselves on a rescue mission behind enemy lines during the battle of La Rochelle. D'Artagnan's enemy Rochefort (Christopher Lee) was caught spying and is enduring a wait before an amateur firing squad learning to load their rifles on the job. While they figure out how to blindfold a condemned man who has only one eye, Athos and Aramis prepare to launch a smoke bomb as cover while Porthos brings the horses for their escape, but the fuse goes out just as the order is given to fire. Fortunately the entire firing squad misses their target, and while they reload the trio manages to extract the spy. He is returned to his master, Cardinal Richelieu (Charlton Heston), then is sent to obtain D'Artagnan's lover Constance (Raquel Welsh). She is the dressmaker and confidante to Queen Anne (Geraldine Chapman) and a valued hostage if they are to deal with Anne's affair with the Protestant sympathizer, the Duke of Buckingham (Simon Ward).Rochefort and his men find D'Artagnan and Constance shopping in the public market. When she picks a melon from a basket, a hand appears from within and seizes her. While she is taken away, D'Artagnan engages his enemy in a duel and manages to deliver a slicing blow to Rochefort's hand; Rochefort upsets a cart of potatoes, which spills and buries D'Artagnan. He is rescued by the mysterious and beautiful spy Milady DeWinter (Faye Dunaway) and taken to her private home. He regains consciousness in her bedroom where she is attending him while attired in revealing lingerie, but despite her charms he departs hastily, promising to come back and "thank her properly." When he leaves, Milady undresses and prepares to step into her bath, but recoils when she sees the water is tinged red. Rochefort was hiding there, letting his injured hand bleed into her bathwater....
