The Green Hornet followed the adventures of playboy-media mogul Britt Reid, the owner and publisher of the Daily Sentinel. As the masked vigilante Green Hornet, Britt fights crime with the assistance of his martial-artist partner Kato, Britt's valet, and his weapons-enhanced car the Black Beauty with license plate V-194. On police records, the Green Hornet is a wanted criminal, but in reality, the Green Hornet pretends to be a criminal in order to infiltrate and battle the criminal gangs, leaving them and the incriminating evidence for the police's arrival. Britt's dual identity is known only to his secretary at the Sentinel, Lenore "Casey" Case and the District Attorney Frank P. Scanlon.
The single-season series premiered September 9, 1966, and ran through March 17, 1967, lasting 26 episodes; ABC repeated the series after its cancellation by the network, until July 14, 1967, when The Green Hornet had its last broadcast on network television.
