Plot
The De La Vegas are a wealthy and prestigious family known throughout the territory. When the youngest son of Don Alejandro de La Vega (Monteczuma), Diego (Rodolfo de Anda), returns from his 4 year stay in Spain, he finds his hometown oppressed by the corrupt military forces. The farmers are being run out of their homes and their land is being used as military camps and/or sold off to pay for military supplies and wages, along with taking the poor villagers and using them as slaves.
The Film starts off with the Zorro character in place and does not show a transformation or origin story other than a brief prelude where Don Diego de la Vega tells his handy sidekick, Kino why he dawns the Zorro persona, (who in other versions is referred to as Bruno or Felipe, specifically the A&E version starring Duncan Reghr) who is also the households butler, and most think is deaf and mute, but shares his secret with Don Diego/Zorro.
Zorro has multiple face offs with the local military and swears to restore order and freedom to the oppressed. However to most, Zorro is nothing but a myth. When the eldest son of Don Alejandro plans to wed the daughter (Helena Rojo) of a fellow wealthy caballero, her father plans to sell his mansion and retire. A buyer emerges (played by Pedro Amendariz Jr) and befriends both families. Upon sealing the deal, he kills the caballero and mortally wounds the elder De la Vega, leaving with the money. He then marks the carriage and surrounding area with the infamous "Z" that Zorro has adapted and is known for. A series of crimes using his own version of the Zorro outfit/mask and impersonating him cause the local towns people to turn on the Zorro. The military starts linking clues together and leads their search right back to the De La Vega's Mansion.
