This was supposed to be a possible series that combines several themes from Star Trek. It takes place on Earth after a nuclear war, and some of the inhabitants faired differently depending on the area. This is similar to the Omega Glory. Some of the people have adapted and evolved into stronger humans as in Space Seed. Some lived under ground like in Spocks Brain. As in Star Trek, this is a small morality play.
The main character is a man from the 20th is awakened, and he has lost scientific knowledge needed by everyone. It found by a group called Pax. They want to end violence on Earth and restore it. They get around the earth in a high speed underground train called a "sub-shuttle." This survived the war. You can clearly guess that in each episode they would visit a different part of Earth in the same way Star Trek visited other planets.
This was not turned into a series, but was reworked into another pilot starring John Saxon. He was more of a Captain Kirk like lead.
Either version would have made a good series.
