This actually could have been a made-for-tv movie. The plot was that there was a private plane that had to land in a small town. The plane survivors noticed that there was sort of a "loop" within the community. For example, a survivor went into a barber shop and saw a client getting a haircut then passed by later and the same person was getting a haircut again. The 4 survivors knew they needed to get out and when they were driving a car they were stuck within an invisible fence. They also noticed an igloo shaped building that the town's citizens were lining up and going in one side and exiting the other. One survivor went to check it out and saw that people in the igloo were vomiting in a trough and the other townspeople were eating it! Yes, disgusting and I was young watching this. Finally, the end showed that aliens had destroyed the earth right when the plane crashed and they saved this small town as sort of a "snow globe". Weird but dying to remember name of this movie.

To be honest with you, I don't have any recolection of this one.. It may have been an episode of the Twilight Zone.. or The Friday Night Frights w/ Edgar Allen Poe.. where Vincent Price was the MC between comercials.. Kind of like "THE TWO HEADED TRANSPLANT " I believe Sonny from Sonny and Sher was the transplant.

Man, that sounds like a trippy story. I would love to find this out. If someone knows, u da man.
