After being shipwrecked, the Robinson family is marooned on an island inhabited only by an impressive array of wildlife. In true pioneer spirit, they quickly make themselves at home but soon face a danger even greater than nature: dastardly pirates.

Diego de la Vega, the son of a wealthy landowner, returns from his studies in Spain and discovers that Los Angeles is under the command of Capitan Monastario, a cruel man who relishes in the misuse of his power for personal gain. Knowing that he cannot hope to single-handedly defeat Monastario and his troops, Diego resorts to subterfuge. He adopts the secret identity of Zorro, a sinister figure dressed in black, and rides to fight Monastario's injustice.
