Opening Narration
Narrator: The year is 1847, the place is the territory of New Mexico, the people are a tiny handful of men and women with a dream. Eleven months ago, they started out from Ohio and headed west. Someone told them about a place called California, about a warm sun and a blue sky, about rich land and fresh air, and at this moment almost a year later they've seen nothing but cold, heat, exhaustion, hunger, and sickness. This man's name is Christian Horn. He has a dying eight year-old son and a heartsick wife, and he's the only one remaining who has even a fragment of the dream left. Mr. Chris Horn, who's going over the top of a rim to look for water and sustenance and in a moment will move into the Twilight Zone.

Christian Horn: What you got there?
Mary Lou: Penicillin. It'll keep away any infection.
Christian Horn: Where did you get it?
Mary Lou: At the drugstore. You feel all right?
Christian Horn: You say this is good for a sickness?
Mary Lou: Well, sometimes, depending on what it is.
Christian Horn: I've got a real sick boy back in the wagon.
Mary Lou: You mean you brought your family with you?
Christian Horn: There were three wagons. And I looked around and I...what is that? What is that? That looks just like...oh, God in heaven, how could that be? That says September 1961 when it's 1847! Who are you? Who are you and where am I? Where is this place? Where am I?

Mary Lou: Well, Doc, what do you think?
Doctor: If you had some bourbon, Mary Lou, I'd prefer that at the moment, but coffee will do for second best.
Joe: (Arriving) Having coffee, huh? Take a look at him, Doc?
Doctor: I did indeed. Malnutrition, that's his major problem, although he's not a bad specimen of a man, I'll say that. And you were right, Joe. He's an interesting customer.
Joe: Must have been the heat, huh? Or something? Well, I mean, Doc, he's just not rational.
Doctor: Now, I'm not a psychiatrist, Joe. I'm just an old-fashioned GP. But Freud himself would have something to gnaw on here.
Joe: Aw...
Doctor: Well, he happens to seem very rational.
Joe: Oh, Doc, come on!

Christian: I may be crazy, or the world may be turned upside down but I know I've been put here for a reason. A reason.

Charlie: Short trip, Chris? Nothing much on the other side, was there?
Christian: You'd be surprised, Charlie. There's a whole lot on the other side of that rim. There'll be highways and many new things. A whole new land. You know what, Charlie? It was people like us, we made it happen.

Closing Narration
Narrator: Mr. Christian Horn, one of the hardy breed of men who headed west during a time when there were no concrete highways or the solace of civilization. Mr. Christian Horn, family and party, heading west, after a brief detour through the Twilight Zone.

The American Territory of New Mexico was not created until 1850, three years after the year mentioned in the opening narration, and in the episode itself. In 1847, it would have been know as Spanish New Mexico.
