Sergeant Garcia returns from escorting Padre Simeon on a trip from San Diego and is surprised to find that almost everyone in Los Angeles has contracted the measles. The doctor has placed the entire pueblo under quarantine and restricted residents to their homes. Even the soldiers cannot leave the cuartel.
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.
