I was completely taken in by this episode. It involves all that goes on as a single man in a remote place has the future of the earth in his hands. He has devised a machine that uses nuclear energy. He thinks it will provide an unlimited supply of light and energy to make the future of earth secure. The other scientists, one in particular, believes it will set off a chain reaction that will put an end to our planet. The episode involves a a great effort to get to this guy and put a stop to what he is doing. Even the President gets into the act. Meanwhile, the monomaniac continues the countdown. We are brought along for the ride. Will he? Won't he? The acting and pacing are excellent for a less-than-thirty-minute broadcast.
