Upon researching the phrase, Felipe and Alejandro learn that Armand is the head of a secret society, the Knights of Aragon, which has been secretly ruling Europe. The United States is deemed a threat to the Knights, so they plan to throw the country into chaos before it can gain too much power. Alejandro is captured and imprisoned by the Pinkertons, who reveal that they forced Elena to divorce Alejandro in order to get close to Armand and learn of his plans without the aid of Zorro as they dislike his vigilante ways and due to their own lack of legal authority to search Armand's home due to California not yet being a U.S. state. Joaquin frees Alejandro from captivity. Zorro goes to Armand's mansion, meets Elena, and eavesdrops on Armand's meeting. Elena, in order to distract Armand, brings him to terrace, & throws keys to armand's vault to Alejandro, as Armand kisses Elena. After accessing secret documents, Alejandro learns that the soap bars are secretly used as an ingredient for nitroglycerin, which Armand plans to distribute throughout the Confederate army, with the help of Confederate Colonel Beauregard, to destroy the Union. Zorro and Elena reconcile, and Zorro prepares to destroy the train carrying the explosives. McGivens arrives at Felipe's church to look for Zorro. Unable to find him, McGivens shoots the priest and kidnaps Joaquin. Meanwhile, however, Armand's butler Ferroq tracks down and kills the Pinkertons and informs his master about Elena's deception. Armand confronts Elena, and takes her and Joaquin hostage on the train carrying the explosives, making Zorro unable to destroy it. Zorro is captured and unmasked in front of his son. Armand takes Joaquin and Elena away and orders McGivens to kill Alejandro. Felipe, having been saved from McGivens's bullet by the cross he wears, arrives, and he and Alejandro overpower and kill McGivens. Zorro catches up with Armand, and they engage in a sword fight. Meanwhile, Elena has Joaquin escape into the back cars of the train, which she disconnects. Elena fights Ferroq in the nitro storage car and throws him and a bottle of nitro out of the car and at the feet of Colonel Beauregard at their prearranged meeting point, killing them. Further
