Ken Ludwig's adaptation of the classic swashbuckling Alexandre Dumas story is a tale of heroism, treachery, close escapes, and above all, honor. The story, set in 1625, begins with D'Artagnan setting off for Paris in search of adventure. Along with D'Artagnan goes Sabine, his sister, who quickly becomes entangled in her brothers' adventures. Soon after reaching Paris, they encounter Athos, Porthos, and Aramis, the famous musketeers. They join forces to defend the King and Queen against the most dangerous man in Europe, Cardinal Richelieu, and the deadliest woman in Europe, Milady, the Countess de Winter.
