Journey to Elba II

M-5 detects the Woden, an unmanned freighter that is not part of the test, and attacks with real weapons, destroying it. Captain Kirk orders M-5 taken offline, but Dr. Daystrom continues to believe it is working correctly, and refuses, saying that he doesn't want to go to the insane asylum on the planet Elba II, where Dr. Janice Lester and Garth of Izar are. Suddenly, the USS Enterprise receives a distress call from Elba II. The Enterprise responds to the distress call and Kirk orders M-5 to set a course for Elba II. The Enterprise warps to Elba II. Little do Captain Kirk and Dr. Daystrom know is that a vengeful woman from Kirk's past is there: Dr. Janice Lester. Dr. Lester was sent to Elba II after the events of Turnabout Intruder following her attempt to steal Captain Kirk's body. Dr. Lester had earned time out of her cell for good behavior and is now determined to get back at Captain Kirk. She monitored all the ships in the area and saw that the USS Enterprise was coming. So she sent out a distress signal because she knew Kirk would respond. When the Enterprise arrives at Elba II, on M-5's recommendation, Captain Kirk assembles a landing party comprised of himself, Mr. Spock, Dr. McCoy, and Dr. Daystrom. The landing party beams down to Elba II, where Janice Lester is waiting for them. Dr. Lester wants Kirk to take her place on Elba II. She almost gets away with it. Then Spock paralyzes her with the Vulcan nerve pinch and takes her back to her cell. Kirk, Spock, McCoy, and Daystrom then beam back to the USS Enterprise. The Enterprise then warps out of orbit, headed for Starbase 6.
