Though Genghis Khan eventually sought peace with the West, his death in 1227 AD puts into power his three war-like sons: Sayan, Susdal, and Kin Khan. These sons quickly overrun the city of Tuleda and take prisoner Princess Bianca, though young Prince Alessio escapes. Hercules comes to the rescue of Bianca, winning her freedom in a tournament in exchange for becoming a slave himself. Forces from the West soon come to re-take Tuleda and Hercules -- freed from his bonds -- helps to dispatch Genghis Khan's three sons while again saving Bianca and reuniting her with her young brother.

The king of Nogara dies, leaving behind a will naming one of his nieces as his successor. Will it be blonde and virtuous Isabella or evil, dark-haired Malva?

Zorro) even though her heart belongs to the mild-mannered poet, Ramon. Malva's ruthless desire for the throne soon alienates Samson and he and El Toro then team up to bring about a proper resolution to the Nogara succession. Meanwhile, Isabella learns El Toto's true identity, an identity which both surprises and pleases her.
