 Britt Reid, daring young owner/publisher of "The Daily Sentinel," dons a mask and fights crime as The Green Hornet. While the police and public believe the Hornet to be a ruthless criminal, the District Attorney knows Reid s secret identity, and welcomes his assistance in fighting racketeers and criminals. Also assisting Reid in his crusade are his secretary, Lenore Case, and his faithful valet, Kato, who is a kung fu expert and who drives the sleek "Black Beauty," the Hornet s well armed car.
