The second season of Zorro opens with Don Diego and Bernardo visiting Monterey, California. They have been sent there by a group of Los Angeles investors to look over an import business. The visitors have barely arrived in town when two men burst into their room and demand the investors' money.

After the Verdugos return to Monterey, Anna Maria enters their home and discovers that her father is missing. Pablo, their former servant, tells her the old man is being held hostage and will be killed unless she hands over 45,000 pesos believed to be in the house.

Expecting another shipment of jewels, Murietta goes to inspect the tannery where they will be stored. There, he spots Pasqual, a peasant who lives there, and whips the old man until he leaves. The shipment arrives accompanied by Dolores Bastinado, recently arrived in the pueblo, who attracts the attention of Sergeant Garcia.

Before he returns home, Sergeant Garcia angers Theresa, a tamale vendor, when he tries to carry out the orders of the acting governor. Luis Rico has decided that all of the vendors must be removed from the plaza despite their objections, and Diego promises Theresa he will try to help.

Joaquin and several followers begin a series of raids against the Especials, which culminates with the beating of Capitan Briones.

She asks Diego to hide her, and with Garcia's assistance, he protects her from the searchers.

Diego's uncle, Estevan de la Cruz, arrives in Los Angeles for an unannounced visit and surprises the de la Vegas when he tells them he plans to be their house guest. Furthermore, he expects them to give a lavish party to welcome him. All of this angers Don Alejandro, but to head off a family dispute, Diego convinces his father that Estevan will leave soon.

Still hoping to strike it rich during his visit to Los Angeles, Estevan shows a great deal of interest in a young woman when he learns she comes from a wealthy family.

Determined to find the missing jewels, Diego and Bernardo visit a local padre in the hopes he can assist them in their quest, but the trip is to no avail.

The kidnappers send word that Anna Maria must meet them if she wants proof her father is still alive, but Diego warns her it is a trick. Romero argues that she must go, so she agrees to go with him, Garcia and Reyes.

Capitan Briones escalates his campaign against Joaquin by ordering that a peon be whipped until he reveals the rebel's hiding place. Zorro uses his own whip to stop Briones, then frees the peon. Shortly after, the real governor returns and Rico explains that his harsh rule was only imposed to make the capital a well-run city. Rico then convinces the governor to offer the rebel a truce so he can explain his case, planning all the while to kill Joaquin as soon as the outlaw turns himself in.
