The USS Enterprise, under the command of Captain Christopher Pike, receives a radio distress call from the fourth planet in the Talos star group. A landing party is assembled and beamed down to investigate. Tracking the distress signal to its source, the landing party discovers a camp of survivors from a scientific expedition that has been missing for 18 years. Among the survivors is a beautiful young woman named Vina.
The 1965 pilot of the series that would ultimately star William Shatner features Captain Christopher Pike (Jeffrey Hunter) and his first officer, Number One (Majel Barrett) on the bridge.
