Zorro is an American action-adventure western series produced by Walt Disney Productions. Based on the Zorro character created by Johnston McCulley, the series premiered on October 10, 1957 on ABC. The final network broadcast was July 2, 1959. Seventy-eight episodes were produced, and 4 hour-long specials were aired on the Walt Disney anthology series between October 30, 1960 and April 2, 1961. For most of its brief run, Zorro's episodes were part of continuing story arcs, each about thirteen episodes long, which made it almost like a serial. The first of these chronicles the arrival of Zorro / Diego to California in 1820 and his battle with the greedy and cruel local Commandante, Captain Enrique Sánchez Monasterio. After Monasterio’s final defeat, in the second storyline, Zorro must uncover and counter the machinations of the evil Magistrado Carlos Galindo, who is part of a plot to rule California. The third story arc concerns the leader of that conspiracy, the shadowy figure of "The Eagle," revealed as vain and insecure José Sebastián de Vargas. It's revealed that the plot to gain control of California is so that he can turn it over to another country, implied to be Russia, for a huge profit. Season one concludes with Vargas’ death.
