The 11th episode of Gene Roddenberry’s science fiction series Star Trek airs on NBC. In an effort to save costs, Gene Roddenberry devises a framing story – referred to behind the scenes as “the envelope” – allowing footage from the rejected 1964 pilot episode The Cage to be used within the context of Star Trek’s current cast as a flashback to a previous crew of the Enterprise. Malachi Throne guest stars in the new footage; Jeffrey Hunter and Susan Oliver are seen in the original footage from The Cage for the first time. 
Stardate 3012.4: The Enterprise is summoned to Starbase 6, apparently by Captain Pike, who commanded the ship before Kirk. Commodore Mendez shows Kirk, Spock and McCoy, however, that Pike was recently paralyzed in an accident and could not have signalled the Enterprise. Spock creates false messages from Kirk and sends them to the ship, instructing the crew that Spock and Pike will beam up immediately, the Enterprise will be piloted by computer to its next destination, and that Kirk will be staying behind. Kirk and Mendez follow the Enterprise in a shuttle, which runs out of fuel when Spock refuses to slow the Enterprise down so the shuttle can come aboard. Spock finally allows Kirk to catch up and then places himself under arrest. Kirk is unable to disconnect the computer from the helm, and Spock’s court-martial begins. Spock offers, as evidence, visual records of a voyage on the Enterprise on which Spock and Pike served 13 years earlier. The bridge then informs Kirk and Mendez that the recording is being sent to the Enterprise from Talos IV – a planet that, according to Starfleet regulations, is absolutely off-limits to all vessels, punishable by death.
