The character of Don Daredevil (Ken Curtis) was created for this serial as the rights to Zorro belonged to Disney by 1951.

A vile political boss named Stratton (Roy Barcroft) hires a gang of night riders to scare off the local landowners so he can claim their lands for himself.

Patricia Doyle (Aline Towne) fights back to keep her property from being stolen from her, with the aid of her cousin Lee Hadley (Ken Curtis) and her neighbor Gary Taylor.

Lee realizes that help is not forthcoming from the government, so he disguises himself as a masked Zorro-like figure called Don Daredevil, and battles the land grabbers in much the same way his grandfather used to do many years ago, as the original Don Daredevil.
