Passport to Danger (1954-1955)
The series chronicled the adventures of a diplomatic courier. Each episode began with a voice-over: "One of the vital functions of the United States Government is to establish and maintain diplomatic relations with other countries. In every friendly and civilized nation in the world there is an American Embassy or Legation. Whether it is Paris or Cairo, Shanghai or any other remote outpost, the most reliable and confidential means of communication is the Courier service. Armed only with his Passport, the Courier, like a global postman delivers the Top Secret dispatches of our Government." Starring Cesar Romero as Steve McQuinn.
More to come (hopefully)
