Schoolhouse Rock! is an American interstitial programming series of animated musical educational short films that aired during the Saturday morning children's programming on the U.S. television network ABC. The topics covered included grammar, science, economics, history, mathematics, and civics. The series' original run lasted from 1973 to 1985, and was later revived with both old and new episodes airing from 1993 to 1999. Additional episodes were produced as recently as 2009 for direct-to-video release.
Diego de la Vega, the son of a wealthy landowner, returns from his studies in Spain and discovers that Los Angeles is under the command of Capitan Monastario, a cruel man who relishes in the misuse of his power for personal gain. Knowing that he cannot hope to single-handedly defeat Monastario and his troops, Diego resorts to subterfuge. He adopts the secret identity of Zorro, a sinister figure dressed in black, and rides to fight Monastario's injustice.
