In the documentary style of The House On 92nd Street and The Street With No Name, FBI Code 98 tells the story of how the agency caught a saboteur who had placed a bomb aboard a company plane nearly killing the top three executives of an electronics firm that's doing those missile guidance systems for those newfangled ICBMs. Of course the Communists are high on the suspect list for those wanting to kill Jack Kelly, Ray Danton, and Andrew Duggan.
National security may be involved, but it was for far more mundane motives that the deed was nearly done. Jack Kelly's overnight bag was switched for the suitcase with the bomb. If a cup of coffee hadn't spilled on him he wouldn't have gotten his bag and discovered the device.
Having an unexploded bomb to work with was great for the forensics team. As J. Edgar Hoover personally put his imprimatur on the film and made an appearance at the end you know the FBI was shown in the best light. Truly their laboratories which Hoover did put in during his long tenure is a thing of wonder.
I won't reveal who or why, but this perpetrator is truly a pitiable human being. And no one is killed in the entire course of the film.
Not a bad film, obviously a tryout for the FBI series to come.
