Film actor Brian Donlevy played Steve Mitchell, international operative whose had two jobs. Get in and out of danger. Donlevy had the voice and delivery to make the show sound plausible, even if it was routine Cold War brush fire stuff. Herb Butterfield was the Commissioner, a taskmaster shrouded in secrecy who served up the situations that Mitchell seems never to refuse. The Commissioner's secretary is played by Betty Moran. She actually seems to care about the Steve's welfare. The Commissioner is just concerned about the fare.
