In 1950 North Korea ( under deadly Kim II Sung) invaded South Korea and the United States correctly came to the latter's defense. See my other reviews like about Mash!
In this ep a colleague of Joe's from the above war meets up with him. Somebody is following the colleague's wife and trying to kill her. This ep was virtually remade a few years later with the same actress ( Jessica Walter) in both shows. Perhaps the latter ep is a speck superior as it is about the run for big time polotical office and this episode is only about Joe's old colleague trying to be a bank president.But the ep has its superb moments like a car scene where the car's brakes are gone and comely women Mannix meets in a bar and him rescuing his friend's wife in that same bar scene!
