A battle between revolutionary Mexicans and the U.S. cavalry brings Zorro onto the scene to enact vengeance for violent acts incurred by the cavalry Sergeant. Once the Sergeant is killed, Don Jose de la Torre retires from being Zorro and settles down to live a quiet life. The brother of the Sergeant, in an act of his own justice, dons the costume of Zorro and terrorizes the countryside. In an act to draw out the true Zorro, the imposter kidnaps Don Jose's wife, making him once again don the mask to rescue her.
