On a planet with an extremely toxic atmosphere, there exists a bubble within which exists a livable atmosphere. Inside the bubble lies a seemingly less advanced society of humans. They reveal to SG-1 that they once were highly industrialized and poisoned the air. They voluntarily simplified their lives and constructed the barrier to keep out the bad air. They also show SG-1 their "link", a neural interface that gives them access to all their computer records, including history, science, etc. When one of the citizens disappears in the night and the entire population forgets she existed, SG-1 begins to think things are not what they appear to be.

As mentioned in the DVD audio commentary at the 6:30 point, by accident a church was shown in the deep background. It was considered unlikely that a church on an alien planet would also display a cross - unless Christianity would be introduced there from Earth, which had happened before (#3.8). See more »

It's a small world, after all!
31 March 2014 | by (Jacksonville, Fl.) – See all my reviews

I'm sorry that I had to use that annoying song from the Disney World ride as the summary title, but nothing else would fit here.

Now I can't get it out of my head.

The situation SG-1 finds here is a world who's pursuit of technology and industrial development so poisoned their atmosphere, that they had to build a protective bubble-dome around themselves to survive.

With all the surviving people inside the dome wearing a neural link to the central computer controlling the dome, as well as being the access all of their stored knowledge, they never realized that as their power source weakened, the computer shrunk the size of the dome shrunk to compensate, and erased all their memories of the people who were lost with every shrinkage.

Everything always appeared normal to them. But when SG-1 finds out the truth, the computer acts to prevent them from letting the people know they're in danger.
