Description: Unlike ABC's The F.B.I., which was one of the network's major successes of the late 1960s and early 1970s, F.B.I.:The Untold Stories had no ongoing characters or storylines; each week's show was dramatized by different actors. Also unlike the earlier program, actual news and surveillance footage was incorporated into the program to add authenticity. One similarity with the predecessor program was that this one was also based on actual cases handled by the Federal Bureau of Investigation of the United States Department of Justice, and was made with the Bureau's full cooperation and involvement.
