Anne Francis plays a beautiful young woman named Marsha White, who goes into a big department store in order to buy a gold thimble for her mother. She takes the elevator to the ninth floor, and after dealing with a rather odd saleslady(played by Elizabeth Allen) discovers that the thimble has a dent in it, but upon returning it, discovers that there is no ninth floor, and that she isn't who she thinks she is either... Memorable episode is both amusing(James Millhollin as Mr. Armbruster nearly steals the episode) and frightening, as age-old fears of identity are once again explored for remarkable effect, right down to the chilling final freeze-frame and end narration.
