An inept British World War II commander leads his troops through a series of misadventures in North Africa and Europe.

The young D'Artagnan arrives in Paris with dreams of becoming a king's musketeer. He meets and quarrels with three men, Athos, Porthos, and Aramis, each of whom challenges him to a duel. D'Artagnan finds out they are musketeers and is invited to join them in their efforts to oppose Cardinal Richelieu, who wishes to increase his already considerable power over the king. D'Artagnan must also juggle affairs with the charming Constance Bonancieux and the passionate Lady De Winter, a secret agent for the cardinal.

Pseudolus is the laziest slave in Rome and has but one wish, to purchase his freedom. When his master and mistress leave for the day he finds out that the young master has fallen in love with a virgin in the house of Lycus, a slave dealer specializing in beautiful women. Pseudolus concocts a deal in which he will be freed if he can procure the girl for young Hero. Of course, it can't be that simple as everything begins to go wrong.

D'Artagnan has become a Musketeer. Protestants hold La Rochelle, and the Queen loves Buckingham, who'll soon send ships to support the rebels. Richelieu enlists Rochefort to kidnap Constance, the Queen's go-between and D'Artagnan's love. The Cardinal uses the wily, amoral Milady de Winter to distract D'Artagnan. But soon, she is D'Artagnan's sworn enemy, and she has an unfortunate history with Athos as well. Milady goes to England to dispatch Buckingham; the Musketeers fight the rebels. Milady, with Rochefort's help, then turns to her personal agenda. Can D'Artagnan save Constance, defeat Rochefort, slip de Winter's ire, and stay free of the Cardinal? All for one, one for all.
