While waiting in a lonely bus station, Millicent Barnes (Vera Miles) is startled to discover that everyone in the station seems to know her. She is further amazed when, peering into the window of a passing bus, she spots a young woman who looks exactly like her. Figuring that Millicent is a mental case, Paul Grinstead (Martin Milner) humors her until the men in the white coats show up -- only to find out that the girl was telling the truth all along. A neat "matte shot" caps this eerie Rod Serling-scripted entry, based, believe it or not, on one of Serling's real-life experiences. First telecast February 26, 1960, "Mirror Image" was the 26th Twilight Zone episode to be filmed, but the 21st to be shown.
