The Story Line
Two men's jealousy over a barroom dancer becomes a central point in Monastario's latest plot to discredit Zorro. A new arrival in town, Carlos Martinez, kills a man during a duel over a dancer in the tavern. The commandante realizes that Martinez bears a strong resemblance to Zorro, so he offers the prisoner his freedom in exchange for his impersonating Zorro. The offer is gladly accepted, for the alternative is death.
Monastario puts his plan into motion by inviting all of the landowners to a party and arranging for the fake Zorro to rob the guests at swordpoint. Diego is suspicious of the invitation, which is out of character for the commandante, and he attends the party suspecting just such a plot. When the substitute Zorro begins his robbery, he's thwarted by the real outlaw in a confusing battle between two apparently identical foes. Zorro's superior fighting skills enable him to best his opponent, and the landowners demand that Monastario put Martinez back in prison to stand trial.
