Mon Chevalier et moi revolves around loyal, street-smart Jimmy the Squire; his best friend, the fun and daring Cat the Princess; and his father Henri of Orange, a charmingly inept but passionately chivalrous knight who might not be the most efficient protector of the realm, but he sure is the funniest. Together, they set out to make the Dark Ages a little brighter and a whole lot more fun.
