The recovering governor is beginning to become irritated by his confinement to the de la Vega home. At times it seems as if the only thing that can pacify him is a music box. Almost as soon as it begins to play, the governor falls asleep. Knowing that the Rebatos are still trying to kill the governor, Diego uses the box to lull him to sleep then Bernardo moves him to safety. The capitan and five rebellious dons arrive at the hacienda and openly announce their plan to kill the governor. They tie up his daughter, Leonar, then spring into his bedroom ready for the kill. Finding it empty, they split up to search the house. Zorro attacks them one-by-one, until only the capitan remains free. Unable to surprise the traitor, Zorro engages him in a swordfight and kills him, thus ending the threat to the governor. The music box finally winds down and the governor awakens. He looks out the window and sees his would-be killers tied to a wall, where a huge "Z" has been carved to publicly announce who saved him.
