The program opened with a trumpet theme by Jerry Goldsmith and this introduction:
Herewith, an Englishman's account of life and death in the West. As a reporter for the London Times, he writes his colorful and unusual accounts. But as a man with a gun, he lives and becomes a part of the violent years in the new territories. Now, starring John Dehner, this is the story of J. B. Kendall, Frontier Gentleman…
