I saw this film in the late '60. It was made about four decades before Enron. I would have liked to do a plot summary but just don't recall it that well. What I do recall was that the subject matter was quite scary when the McGuffin was finally revealed at the end. Inger Steven and Don Murray were a typical suburban couple caught up into somethings way beyond their understanding. The story revolved around them not having any idea about what it was that they knew. And what did they know? Organized crime having so much money decided to buy into or buy up legitimate corporations and businesses. That wasn't unusual because that seems to be the way of the world in many quarters, but this story had unique twist, i.e., the crime families were going to buy up utilities, railroad, water, etc., to eventually monopolize them. It seemed to me that in the film they discussed that there eventually would be shortages either real or contrived. When that happened, they would be able to set or control the prices of necessities to any amount they wanted and no one could do anything about it. In 2008, the Borgia Stick has proved to be more fact than fiction except that the organize crime people today wear more expensive suits and attend the right schools. It was a great film that need to be out on DVD.
