Feb 18, 1977

Hunter’s archenemy, a Soviet agent and killer known as Bluebird, is suspected of killing an American who betrayed the Soviets after leaking American nuclear secrets to them.

The murders lead Hunter and Marty to a Soviet plot to discredit an American nuclear-powered electric plant design. This was the first episode of the weekly series, which used the new premise of Hunter and Marty being counterespionage agents.
