Gunnar Malstrom is one of the leaders of the Pendulum, a secret terrorist organization seeking to overthrow the United States government. The IMF is informed that the Pendulum is shortly planning a major attack on the government, code-named Nightfall. With no knowledge of other members of the Pendulum, the IMF lures Malstrom to the headquarters of a phony corporate conglomerate, where they learn bits and pieces of the plan -- but fail to uncover that the official who is supposedly the target of Nightfall has already been replaced by a Pendulum double.

Casey lures Malstrom to the headquarters of a fake corporation, "World Resources, Ltd." that the IMF has set up. An establishing shot shows that the headquarters has an unusual "inverted double pyramid" design, in which each lower floor gradually becomes wider than the floor below it until the middle level, after which each floor becomes proportionately smaller for the same number of stories. This building is actually the library on the campus of the University of California at San Diego as it looked in the early 1970s when this was filmed. (It can also be seen in the pilot of "Simon and Simon," which actually was set in San Diego.) See more »

Exciting, crisply paced episode
8 July 2017 | by See all my reviews

So, as the curtain rings down on this great American TV series, we get some good adventure and teamwork in this outing.

After Martin Landau and Barbara Bain left MI at the end of Season 3, the ratings took a dip. Leonard Nimoy came on board for Seasons 4 and 5 to in effect take the Landau role of the disguise master and, frequently, the ringer who infiltrates the bad guys. In Season 4 we had no consistent female agent; in season 5 there was Lesley Ann Warren. Each of these chapters in MI history had their own merits. For Seasons 6 and 7, we had a core team of Jim, Barney, Willy and Casey, the beautiful Texan Lynda Day George. I have a lot of fondness for that final team! Without someone like Landau or Nimoy on the team, frankly Jim and Barney were even more crucial to the stories, which was fine with me. Lynda was tops. Dean Stockwell does a good guest turn here; nice exterior scenes; engrossing race against time plot. Another satisfying winner from one of the all time greatest TV series.
