Kirk finds that the monolith can be opened by the combination of sounds found in the order "Kirk to Enterprise," but when he enters the obelisk, he is attacked by waves of energy that erase his mind. With no time to spare, Spock and McCoy have to return to the Enterprise without Kirk, and begin trying to use the ship's tractor beam to divert the asteroid.

Stardate 5630.7

...or is there in beauty no truth? Miranda Jones, a telepath who studied mental disciplines on Vulcan, arrives with Ambassador Kolos, a Medusan - an alien life form whose physical form is so hideous, humanoid life forms are driven insane if they look upon him.

Stardate 5476.3

McCoy tells Kirk that the most recent routine medical exams of the entire crew have revealed a case of a terminal but non-contagious disease. The victim is McCoy himself. Kirk recommends that the doctor resign immediately, but before the discussion gets any further, Kirk leads Spock and McCoy on a landing party mission to the asteroid-like vessel called Yonada, carefully disguised inside to make it appear to the humanoid inhabitants that they are on the surface of a planet. Kirk finds that the "world" is controlled by a computer known by the residents of Yonada as the Oracle, and the Oracle's instructions are being taken as a religious order. The high priestess catches McCoy's eye and asks him to remain with her - an offer which, considering the doctor's current state, McCoy finds tempting.

Stardate 5693.2

The Enterprise arrives at the last known position of the U.S.S. Defiant (NCC-1764), an area of uncharted space, to search for the missing starship. When the Defiant appears on the viewing screen enshrouded in a strange green glow, Spock is unable to scan the vessel on his sensors. Kirk beams over to the Defiant with a boarding party to investigate and finds the entire crew dead. What's more, the Defiant seems to be trapped in an interphase between two different universes. A power loss partially disables the Enterprise transporter, but the landing party manages to beam back to the Enterprise except Kirk who suddenly disappears along with the Defiant. Spock calculates that the next time to interphase will be approximately two hours, and that the captain can be rescued at that time. As the Enterprise begins to experience the same problems that doomed the Defiant: power loss, weakness and insanity among the crew, an alien vessel appears and demands that they leave Tholian territory or be destroyed. Spock explains that they are involved in rescue operations and requests that they stand by until the next interphase. The Tholians agree to wait, but when the next interphase occurs, the captain cannot be recovered due to the disturbance in space caused by the Tholian intrusion. The Tholian ship opens fire on the Enterprise, and when Spock returns fire the Enterprise manages to disable the Tholian vessel but at the cost of a further power loss and growing insanity among the crew. Another Tholian vessel appears, and together they begin construction on an energy web designed to capture the Enterprise. Spock declairs the captain dead and urges hurried repairs to the Enterprise before the Tholians complete their web. But once Kirk is seen by the bridge crew still trapped in interphase, Spock determines that they might still be able to recover him during the next interphase which will occur just as the Tholians will be completing the web. The Enterprise manages to disappear into interphase and reappear several parsecs from Tholian territory. Kirk is beamed aboard unharmed after being pulled to safety in the ship's transporter field.

They need to repopulate their species, and find that speeding human males up to Scalosian speed will meet their needs.

The dohlman turns out to be Elaan, one of the most striking examples of the women of Elas, whose tears, according to legend, leave any man susceptible to her charms. Petri's duty on the slow voyage back to Troyius is to train the savage Elaan in the more civilized ways of the Troyians, a lesson she does not willingly take on. After stabbing Petri, throwing numerous tantrums, and ordering her guards to refuse Kirk permission to resolve any disputes, Elaan sheds a tear, which infects Kirk, clouding his judgement at precisely the wrong time when a Klingon warship enters the sector.

The woman continues to appear, naming her victim on arrival and killing them by touch. Sulu is nearly killed by her, and the woman appears on the Enterprise as well, sabotaging the engines so the ship will never retrieve Kirk's survey team, stranding them - as well as the crew of the Enterprise - with an unpredictable murderer.

Stardate 5818.4

Beaming down to pick up a consignment of zenite from the planet Ardana, the home of Stratos, a city that floats above the surface of the planet, Kirk and Spock, who are there to pick up a consignment of zenite, are ambushed by mineworkers known as Troglytes. The attack is cut short by the arrival of Plasus, a high advisor from Stratos, who says that a disruptive group of protesting Troglytes probably stole the zenite shipment, which was missing. On Stratos, which Plasus says is safe, there is also evidence of Troglyte terrorism. Kirk and Spock discover that the Stratos dwellers live an easy life thanks to their planet's unique mineral resources at the expense of the Troglytes, who get no reward for extracting those resources. When McCoy finds that the raw zenite being mined by the Troglytes is having an adverse affect on their health, Kirk takes it upon himself to upset the balance in favor of equality.

Stardate 5906.4

Over the planet Excalbia, the Enterprise is intercepted by who appears to be Abraham Lincoln, floating through space. Beaming aboard, Lincoln is welcomed by Kirk, who is somewhat awed by the presence of one of his most revered figures of history. "Lincoln" extends an invitation to Kirk and Spock to visit the planet, whose normally lava-covered surface sprouts a zone of Earthlike safety just for the landing party. Kirk, Spock and Lincoln are joined on the surface by an image of Surak, who initiated the doctrine of emotional restraint on Vulcan. A rock-creature appears and introduces Kirk and Spock to four more illusionary figures from history, this time the fiercest conquerors, tyrants and villains of the past, from Earth's Genghis Khan to Kahless the Unforgettable, who, as Surak did for Vulcan, set the standard of behavior for the Klingons. The creature pits the best and most noble - Kirk, Spock, Lincoln and Surak - against the most vile historical figures. The rewards for Kirk and Spock, should they survive, are their lives, and the lives of everyone aboard the Enterprise.

14/03/1969    All Our Yesterdays

Stardate 5943.7

Arriving at the moon Sarpiedon, whose mother planet is due to explode in three hours, Kirk, Spock and McCoy find just what the ship's sensors indicated on the surface - no life forms, though an advanced civilization obviously once existed. But they then find several copies of Sarpiedon's librarian, Mr. Atoz. Some of the clones are helpful, others belligerent, but they all tell the landing party that all the people of Sarpiedon have already escaped to safety, and Atoz, thinking that Kirk and the others are natives who arrived late, advises them to do the same. The library turns out to be a file of "time periods" into which a device Atoz calls the atavachron can propel them, as it has already provided an escape for the rest of the moon's inhabitants. Hearing a woman screaming, but not realizing that she is one the other side of tha atavachron's time portal, Kirk leaps into a time period similar to the 1800s, and Spock and McCoy stumble into an ice age trying to retrieve him. All three must try to survive long enough in their respective environments for the time portal back to Sarpiedon to return - if that moon still exists in the 23rd century for them to return to.

03/06/1969    Turnabout Intruder

Stardate 5298.5

Visiting Dr. Coleman and the ailing Dr. Lester, a colleague of Kirk's from Starfleet Academy who has always envied him due to her inability to achieve a captaincy in a male-captains-only Starfleet, Kirk is rendered unconscious by Lester. It turns out to have been a trap, and Lester puts herself and Kirk into an unknown device that transfers their minds into one another's bodies. Lester, in the form of Kirk, doesn't have time to kill Kirk (now in the female body). Lester and Coleman make every attempt to leave Kirk on the planet, but must bring "her" aboard to save face. Kirk, still suffering a severe shock from the mind transfer, is unable to warn McCoy about Lester's plan to command the Enterprise (especially when Lester keeps ordering Kirk sedated). Lester, however, is unable to conceal her lack of knowledge of command procedures and, more specifically, Kirk's character, and when Spock learns the truth and attempts to help Kirk, Lester has him placed under arrest and tries to speed Spock's court-martial toward a conclusion which would have Kirk and Spock executed.
