Paul de Kock and Adolphe Guénée present a humorous dramatic prequel to the well-known Alexandre Dumas tale of The Three Musketeers. The four would-be adventurers--D'Artagnan, Aramis, Porthos, and Athos--serendipitously encounter each other at an inn outside of Paris, the city where they're heading to escape their present situations and find their fortunes. They also meet there a beautiful noblewoman fleeing an unwanted marriage imposed on her by Cardinal Richelieu--and the girl's elderly husband, the lecherous Marquis. Back and forth across France they chase each other, seeking to rescue the woman's good name. While the drama can be intense at times, it's all in good fun, and ultimately, of course, everything works out for the best--with the four gentlemen earning their commissions as King's Musketeers!
