In Search Of...: Season 5

The fifth season of in Search of opens with a speculative half-hour concerning possible governmental cover-ups of UFOs. In this and the 23 subsequent episodes, saturnine host/narrator Leonard Nimoy poses innumerable questions while the series' production staff works overtime to provide the answers, though many of those answers are left for the viewer to determine. Among the topics covered this season (ranging from the fact-based to the phenomenal) are faith-healing, the effect of the phases of the Moon on human behavior, the sinking of the Lusitania, the Hindenburg disaster, the Great Wall of China, and the Salem witch trials, along with several celebrity-based 'mystery' episodes focusing on the likes of Marilyn Monroe, Lee Harvey Oswald, and Jimmy Hoffa. One of the final episodes in the season - though, curiously, not the final episode - speculates on the end of the world.
