Humiliated by Zorro, Basilio gets his revenge by arresting Sergeant Garcia and hoisting him in the air in the public square outside the cuartel. A large sign dares Zorro to rescue Garcia, but Diego knows Basilio will have hidden lancers throughout the area. When night arrives, so does Zorro, using Bernardo to help create a diversion that draws the soldiers out of town. Bernardo lures Basilio out of his office by offering to take him to Zorro, but the waiting outlaw instead uses his rope to hang the politician upside down in the square. The lancers return to free Basilio and he rides to the de la Vega hacienda to arrest Bernardo. Basilio accidentally discovers one of the house's secret passages. As he begins to explore, he surprises Diego and knocks him unconscious. Having finally solved the mystery of Zorro, Basilio celebrates by donning the black costume and mask, then steps outside on the balcony to savor the moment. Capitan Mendoza, who is waiting outside on guard duty, sees the figure of the infamous outlaw and shoots Zorro dead. Much to his surprise, he discovers he has killed Basilio, thus unwittingly protecting Zorro's secret identity.
