Welcome to the Star Trek Original Series pages. The Original Star Trek chronicled the voyages of the USS Enterprise on its 5 year mission. The series is unusual because it is almost the only show that was asked to make two pilot episodes since the first pilot was not accepted but the second one was. The concept of the first pilot wasn't completely scrapped but incorporated into a later episode and revamped. Star Trek was envisioned to be the equivalent of the then-popular tv show entitled "Wagon Train". In fact it was referred to as "Wagon Train to the Stars."
Here you will find on each page the episodes of a particular season. You will find; Title, Air and Star Date, Guest Cast, Plot Summary (no spoilers), Writer(s), and Director.
