Actually it's the great-grandson of legendary 19th century do-gooder Zorro who rides in this 12-chapter Republic serial. Villainous modern-day tycoon Marsden (Noah Beery) supervises the activities of a western outlaw gang from the plush confines of his Manhattan skyscraper. It is Marsden's hope to grab control of a new California-to-Yucatan railroad, and there isn't any low to which he will not stoop to get what he wants; he even deploys a modernistic machine gun and an art-deco twin-prop fighter plane. Recalling the heroic exploits of Zorro, a group of beleaguered Californians send for the masked hero's great-grandkid James Vega (John Carroll), only to find out that he's an airheaded playboy, more interested in his golf score than saving humanity. But like his famous ancestor, Vega rises to the occasion, adopting the mask, cape and whip of Zorro to settle Marsden's hash for good. Outside of its usual quota of thrills and spills, Zorro Rides Again is one of the few serials that can boast a theme song ("Zorro rides again -- riding along, singing a song" etc.)
