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.

Diego continues his investigation into Señor Verdugo's business by riding to his house, where Verdugo greets him and Bernardo with his arm in a sling. Although Verdugo claims an old injury is bothering him, Diego suspects he may be the leader of the robbers, so he sets a trap.

Lieutenant Rafael Santos is ambushed on his way to Monterey and left for dead when the ambushers take his identification and uniform. One of them, a killer named Anastacio, puts on the uniform and rides to Verdugo's, where Diego is discussing the investment deal.

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.

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.
