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.
To impress the other squires, Jimmy pretends that Bjorn is his pet and Bad Jack threatens to burn Epic to the ground.
The Queen calls a truce during battles in order to give her nights a break, and the two sides enjoy a minstrel concert.
When Jimmy and Cat use science to win the sorcery faire, their classmates believe they are masters of the Dark Arts.
Jimmy encourages Cat and Bjorn to spend the day with their parents, but the Queen and Bad Jack's plans interfere.
