A mystery develops when a teenage girl arrives in the pueblo and asks for directions to a ranch no one has ever heard of. Anita Cabrillo has been studying at a boarding school, and she has come to visit her father, whom she has not seen in many years. Anita attracts a small crowd when she asks about Don Cabrillo, who is unknown in the city, and Diego offers to let her stay at his house until the mystery can be solved. Anita has barely arrived there when she screams, then tell Diego and Don Alejandro that someone tried to enter her room. Alejandro begins to think Anita is subject to delusions, but Diego senses that someone may be trying to scare her out of town for some unknown reason. The intrigue continues when Anita sneaks away that night and rides into the woods. Zorro follows and hears a voice that warns Anita to return to Spain or be killed. Believing her to be in immediate danger, he rushes in to save her. Instead, he scares her into attempting to escape, and only Tornado's great speed enables Zorro to save Anita from riding off a treacherous cliff in the dark.
