This is the first episode ever, and it’s actually pretty good. Though it moves slowly, the end isn’t bad. An air force captain awakens to find himself in a town with no one there - throughout the episode it seems as if they are there, but just around the corner. He feels as if he is being watched, but he can never find anyone.
At the end, we find that he is indeed being watched. He has been under observation for about two-and-a-half weeks, or the time it takes to orbit the moon and return to earth, and they are trying to determine the effect on a man’s mind during that time. The subject was locked in a cubicle the whole time.
Not the best episode by far, but a good start to a great series.
