Narrator: The major ingredient of any recipe for fear is the unknown. And here are two characters about to partake of the meal: Miss Charlotte Scott, a fashion editor, and Mr. Robert Franklin, a state trooper. And the third member of the party: the unknown, that has just landed a few hundred yards away. This person or thing is soon to be met. This is a mountain cabin, but it is also a clearing in the shadows known as the Twilight Zone.
