This was the third attempt to get a series from Gene Roddenberry's Genesis II concept, this time without any involvement from Roddenberry. The basic plot is similar to many SF series with returning astronauts traveling across a new Earth after some sort of cataclysm, searching for remnants of their civilization. As an example of what the regular series might look like, the pilot is broken into two separate stories. The first involving a culture who may have discovered the secret of immortality. But, at what cost? The second, more elaborate episode follows the astronauts into a battle for survival against a tribe of primitive forest dwellers. Well made and cast with well known actors, the pilot is action packed and interesting, but tired at the same time.
