At the request of the king, Captain Treville sends three of his best musketeers to find one of their missing brothers in arms. The missing musketeer had been sent on a quest of vast importance. He's carrying letters for King Louis and never reached his destination. The three musketeers are eager to find the missing man and bring him back safely as well as his important cargo. Athos, Porthos and Aramis are each incredibly different. Athos is a brooder while Aramis is fond of the ladies. Porthos brings a levity to their adventures. All of them are loyal to the king and to their country. They'd do anything to protect it.
