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? Each woman relies on a hero to locate the will. Malva hires the bare-chested strongman Samson while Isabella relies on the masked El Toro (a.k.a. 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.
