The Spaniards under Charles V aim to occupy all of Italy with the help of traitorous allies like Don Lorenzo. Lorenzo conspires to marry off his supposed niece Isabella to Charles V’s nephew, Prince Rodriguez, to confirm Spain’s dominance. The Black Devil, a heroic masked avenger, falls in love with the fake Isabella and takes vengeance on Lorenzo with the help of his friend Ruggerio and his men.
