17th century France: Young D'Artagnan leaves his home and travels to Paris with dreams of joining The Musketeers of Guard—the glamourous and gallant group of men who guard Louis XIII, the King of France. There he meets Athos, Porthos and Aramis, the three best musketeers and inseparable friends who believe with all their heart in the words 'all for one, one for all.' D'Artagnan rents an apartment above the shop of one Monsieur Bonacieux, hoping to settle into Parisian life and become a proper musketeer quickly.

What the young and gallant D'Artagnan does not realise is that he has, inadvertently, landed himself in the very centre of one of the foulest conspiracies in monarchist France.

There are love affairs and intrigues, ambushes and wild rides, duels and murders. And as the famous American author and editor Clifton Fadiman says, 'it is all impossible and it is all magnificient.'
