Young Grimbert, heir to the Margrave of Turin, wanted to be a knight since childhood. Brought up on chivalric novels, painfully ambitious, ardent, he cannot imagine life without glorious knightly achievements and sees himself as a noble defender of the faith, a fearless warrior and champion of the Turin March. He must be a knight, period. He must dispense justice with the fire of large-caliber guns, protect the oppressed, punish heretics and do what is prescribed for a glorious knight. And even if he is only twelve, even if his armor is a rusty self-propelled wreck, causing laughter among his father’s knights, even if, of all the servants in his retinue, only faithful page... He will accomplish his feat. He will prove to the whole world that he is worthy of dedication. And if the world does not believe in the power of Grimbert of Turin, so much the worse for the world!..
