Após a morte de Filipe II, Rei de Navarra, as princesas Malva e Isabella disputam quem irá suceder o monarca no trono. Malva, cruel e ambiciosa, sentindo que a escolhida será Isabel, decide desaparecer com o testamento do falecido rei antes que ele seja tornado público. Para isso, cria um plano mirabolante que acaba jogando dois heróis, Zorro e Maciste, um contra o outro.
In the first half of the 1600's, France is at war with Spain. The cousin of the king of Spain, Isabella, is held captive in the French castle, and the Count of Seville is sent to France as a diplomat. While there, he is escorted by the Three Musketeers, who discover that he has secretly made a deal with Cardinal Richelieu to disclose Spanish military secrets in exchange for Isabella's release. However, he is merely bluffing and plans to take Isabella by force. When the musketeers discover this, they come to his aid, and together the four of them work at freeing the Countess. Meanwhile, the Count doubles as Zorro to free the Spanish court from a treacherous suitor.
A man returning home after having fought in the Civil War discovers that corrupt politicians have taken over the county and are terrorizing and shaking down the citizens. He dons the costume of his ancestor, the famous Zorro, and sets out to bring them to justice.
A mix of swashbuckling and Spaghetti western: a light hearted adventure of Zorro in which the hero has to support good noblemen, sustained by the peones, against an ambitious landlord and a bad alcalde.
In Old Calfiornia, an unscrupulous adventurer massacre Indians in order to find an ancient (and precious) talisman they are supposed to hide. Zorro will be on the rescue to protect both the pioneers and the Indians. This adventure has very little in common with the traditional swashbuckling backstage of Zorro's films but many elements of a western film.
