"Behind the Locked Door," a popular, much-requested episode which took place in total darkness, was repeated several times during the years. Two archaeologists discover a century-old wagon train that had been sealed in a cave following a landslide. When their Native American guide is mysteriously and brutally attacked, the two, now lost in the darkness, conclude that the descendants of the wagon train are still living in the cave. The popularity of the series spawned other supernatural shows, such as The Sealed Book. With scripts by a Mysterious Traveler writer and Tarplin as host-narrator, The Strange Dr. Weird was a nearly identical program. THIS EPISODE: July 6, 1948. Mutual network. "The Man Who Vanished".
