Don Diego de la Vega is a young man of high social position from the town of Los Angeles, who fights against tyranny under a secret identity: Zorro.

He is helped by Tempest (originally "Tornado"), his black horse, and Miguel, a young swordsman (replacing Don Diego's traditional mute butler Bernardo).

Captain Ramón is helped in his task of capturing Zorro by González, a foolish sergeant who is friends with the De La Vega family.

Zorro showed the viewers information about California and the influence of Spanish language and culture in the region at the end of each episode.

In 1981, toy manufacturer Gabriel released a line of Zorro action figures that tied in with Filmation's animated series.
