The Deadly Years (episode)

The Enterprise discovers a colony full of rapidly ageing scientists. Whatever caused the rapid aging of the scientists soon afflicts the ship's landing party as well. Kirk, Spock, McCoy, and Scott are shocked to discover that they are ageing decades each day and will soon die unless a cure for their condition can be found. The unaffected Chekov may be their only hope for survival.
== Summary ==
=== Teaser ===
The is on a routine mission to resupply the experimental colony at Gamma Hydra IV. Captain Kirk, Mr. Spock, Dr. McCoy, Scott, Lt. Galway, and Ensign Chekov beam down. While the landing party is spread out looking for the missing colonists, Chekov enters a darkened building that he has been asked to search. As the lights come on, they reveal the dead body of a very old man – and Chekov runs out, terror-stricken. Chekov is panicking and is in the full throes of terror when the rest of the landing party find him; they go into the building to investigate. McCoy reveals the man's cause of death to be natural causes, extreme old age. Spock finds this impossible, since he had checked the records before the group beamed down and found none of the colony members were over 30. Then, two elderly people wander in – these are colony members Robert Johnson, who claims to be only 29; and his wife, Elaine, who claims to be 27.
=== Act One ===
:"Captain's log, stardate 3478.2. On a routine mission to resupply the experimental colony at Gamma Hydra IV, we discovered a most unusual phenomenon. Of the six members of the colony, none of whom were over 30, we found four had died and two were dying… of old age!"
In the Enterprise in sickbay, Kirk tries to question Mr. Johnson, but being of advanced age, he fails to understand fully what the Captain is asking him. He fills in his passengers, Commodore Stocker, Yeoman Atkins, and Dr. Janet Wallace, Wallace also being an old flame of Kirk's past. Kirk promises to keep them all informed and that they will remain in orbit until the mystery is solved. Commodore Stocker expresses his pressing concern to reach Starbase 10, and Kirk says he will do everything he can to get Stocker there. Everyone leaves the briefing room and Dr. Wallace and Kirk reminisce about the past for a moment and how their careers got in the way of their relationship over six years ago.
Kirk goes to the bridge and gives Sulu the order to maintain orbit, and Spock informs him that a rogue comet passed near the planet some time ago, but is unsure whether it had any effects on the planet. Commodore Stocker tries to again push the Enterprise to leave immediately for Starbase 10, claiming the instruments there would be more effective. Kirk politely refuses the Commodore's request and leaves the bridge, repeating the command to maintain orbit – much to Sulu's and Spock's puzzlement.
Meanwhile, in sickbay, McCoy and Nurse Chapel have been unable to help Mr. and Mrs. Johnson, and both have died. A perplexed Lieutenant Galway visits McCoy, complaining about suffering a sudden loss of ; McCoy expresses hope that hypersonic treatment may clear it up, which it unfortunately does not. Meanwhile, Kirk is in his quarters, where he is about to put on a fresh uniform shirt, when he calls Spock on the bridge to tell him to look into a comet that had recently passed the planet. Spock, of course, replies he is already doing so as per Kirk's orders, which leaves Kirk a little confused. As Kirk is about to put on his shirt, he suddenly experiences shoulder pain in his right arm. Kirk goes to sickbay to tell Dr. McCoy of this ailment, and jokes about McCoy's hair getting a little grayer. Kirk thinks it's merely a strained muscle, but McCoy's initial exam reveals advanced arthritis in Kirk's shoulder – which Kirk refuses to believe at first. But then Scott walks in, complete with gray hair and wrinkles.
=== Act Two ===
:"Captain's log, stardate 3479.4. The Enterprise personnel who beamed down to the planet's surface – Dr. McCoy, Engineer Scott, Mr. Spock, Lieutenant Galway, and myself – are all showing definite signs of ageing. Only Ensign Chekov appears to be normal."
Everyone that had been in the landing party is showing definite signs of accelerated ageing, with the sole exception of Chekov. Most of the party members are aging at approximately 30 years a day (although Galway was the youngest of those afflicted, she appears to be ageing at a vastly faster rate than anyone else), and McCoy is at a loss for the cause. He has run a complete physical on Chekov and found nothing to explain it. Spock estimates that they all have less than a week to live and that in lesser time, they will be little more than mental vegetables. Though Spock is showing no obvious physical signs, he admits to suffering from lethargy, memory and vision loss; and the ship's temperature is feeling increasingly colder to him. Kirk sends Scott and Galway back to their duties and leaves McCoy to do yet another physical on Chekov. Scott is already so deteriorated and weakened that Spock needs to help him walk.
As Kirk heads back to the bridge, he exchanges a mildly flirtatious conversation with the concerned Dr. Wallace. The tone changes however, when Kirk realizes that her deceased husband, Theodore Wallace, was 26 years her senior. Kirk rejects her advances, and inquires if Dr. Wallace's affections to him are because of his current appearance; and also concerned that it may be out of pity for his sad condition.
As Chekov sits at his navigation console on the bridge, he gripes to Sulu about McCoy's constant examinations of him and him giving all sorts of samples. "If I live long enough, I'm going to run out of samples." Sulu reassures him, "You'll live." But Chekov continues to gripe, "Oh, yes. I'll live. But I won't enjoy it."
An elderly Kirk arrives at the bridge while a concerned Commodore Stocker looks on, and the bridge crew can see that Kirk's advanced age is clearly taking its toll. Kirk gives orders, then forgets giving them — and even fails to remember signing moments before a fuel consumption report brought by Yeoman Atkins. Kirk even falls asleep in his command chair. A gray-haired Spock wakes Kirk and tells him that the comet is indeed the source of the problem. By now, even Spock appears to be tired. The orbit of Gamma Hydra IV had recently caused the planet to pass through the comet's tail. Though no regular levels of radiation were detected, there were extremely low levels of radiation, which is the probable cause. Kirk then orders Lieutenant Uhura to send a coded message to Starfleet and to use code 2 since they are close to the Romulan Neutral Zone. Uhura reminds Kirk that the Romulans have already broken code 2. A befuddled Kirk orders her to use code 3 and to relay the information about the comet. He then tells Sulu to move the ship to a higher orbit; and when Sulu indicates that he had already given that command, Kirk yells in frustration, "I fail to understand why each one of my commands is being questioned!"
McCoy confirms the radiation poisoning theory, and Kirk returns to the bridge. Spock then informs McCoy that the ship has become increasingly cold and he has had to increase the temperature in his own quarters to 125 degrees to which McCoy informs him that he will not be making house calls to Spock. Dr. Wallace then tells McCoy that none of the conventional means for radiation therapy will work in this case.
In a corridor, Commodore Stocker meets with Spock, informing him of his concern for Kirk's ability to command. He asks Spock to take over as captain, since Vulcans have a much longer life span than Humans. Spock reminds the commodore that he is also feeling the effects of the aging and that he also is half Human. Stocker asks Spock to conduct an extraordinary competency hearing, which according to regulations is Spock's duty as first officer. Spock, wanting to spare Kirk of any more suffering than he is already going through and the humiliation of an almost guaranteed judgment against him, tells the commodore that he has duties to attend to. Stocker holds firm and insists to Spock that a competency hearing is mandatory by regulations. Spock reluctantly agrees and announces that he will convene the hearing at 1400 hours.
As McCoy continues to examine Chekov, an even more aged Lt. Galway arrives at sickbay, where she suddenly collapses in Kirk's arms and dies. McCoy speculates that Galway's metabolism caused the disease to affect her far more severely, resulting in her early death, and that they themselves have little more time. They may have no longer than days remaining to them, perhaps even hours.
=== Act Three ===
Spock conducts the competency hearing. Scott is by now much older, looking tired and depressed. Kirk and McCoy are also in terrible condition. A reluctant Atkins, Uhura, and Sulu all testify about Kirk's failing abilities. McCoy also reluctantly confirms the computer analysis of his medical examination. Testifying, Kirk tries to maintain his control, but it is quite obvious that his mind and deteriorated body are failing, and he digs himself a deeper hole by going on a long, rambling speech in which he erroneously refers to the planet that they are orbiting as "Gamma Hydra II". He is removed from command and to his dismay, the inexperienced Commodore Stocker assumes command.
Kirk, despite his senility, does nonetheless retain enough common sense to predict correctly that Stocker, with no command experience, and in Kirk's words, a "chair-bound paper pusher" or, essentially, an official in uniform, would be a poor choice to command the Enterprise, and tries to order Spock to take command. When Spock rebuffs Kirk and reminds him that he no longer has power on the Enterprise, it deeply hurts him and temporarily causes a rift between the two. Kirk then fruitlessly tries to justify his command ability to Janet, telling her that his brain is still as sharp as it ever was, despite evidence to the contrary. Kirk asks Wallace if she sees him getting older, for which she cannot provide an answer.
Later, a very old and gray Kirk, along with an equally gray Spock and McCoy, review again their beaming down to the planet. Spock then reminds them that the only time Chekov was not with them was when he went into the building and discovered the body; whereupon, terror-stricken, he fled from the building in a state of near panic. McCoy postulates that the increased adrenaline levels somehow may have protected Chekov from being afflicted.
Stocker, who has no field experience, plots a shortcut to Starbase 10 through the Romulan Neutral Zone and, of course, the Romulans immediately attack. The Enterprise is quickly surrounded by several Bird-of-Prey ships, as a shocked and frozen commodore tries to decide what to do. Kirk wishes to go to the bridge. A terminal McCoy tries to dissuade him and tells him that they are both finished.
=== Act Four ===
The Romulans continue to attack the Enterprise while Stocker tries to establish communication. Spock, with Wallace's assistance and even through his own suffering from handicapping cold sensitivity, races against time and synthesizes a crude adrenaline serum, but it could either cure or kill. Kirk, unable to endure any longer and determined to get back to the bridge, demands the first shot stating he is already about to die anyway (either from the serum, destruction of the ship or the aging process) – and upon receiving it, he starts to scream and writhe while held down with restraints on his bio-bed.
Stocker feels that the only way to get the Romulans to stop is by surrendering. But Chekov reminds him that Romulans do not take prisoners.
Suddenly, a fully recovered Kirk arrives on the bridge and retakes command. On purpose, he instructs Uhura to post a message to Starfleet, using code 2, that he plans to self-destruct the ship and take all the Romulan ships with him by using the "recently installed" corbomite device. Spock looks exhausted, but relieved.
As Kirk had expected, the Romulans tap into the message and start to move out of the way. Kirk uses this opportunity to warp the Enterprise out of the Neutral Zone and back to safety. McCoy boards the main bridge, being shown to have recovered, and tells Kirk that Scott is fine, though he pulled a muscle when his body reacted to the serum. The antidote is a success, even if the procedure is very painful to Humans, and even more so for Vulcans. Kirk points out to Stocker that there is very little a star base can do that a starship cannot, but Stocker points out that he is now fully aware of what a starship can do "with the right man at the helm." McCoy tells Spock that an especially potent dosage of the antidote has already been prepared for him, that all breakable objects have been removed from the infirmary, and that they can administer the radiation-poisoning antidote whenever Spock is ready. Spock is in visibly bad shape, and he asks to receive it now. Kirk remarks that the events of the past day will be an experience they will remember, even in old age – which hopefully will still be far off. Kirk orders Sulu to take command of the Enterprise, steady as she goes, which the helmsman repeats. Kirk replies that he thought he already said that.
The Enterprise flies off through space, on its way to Starbase 10.

=== Production notes ===
* The brownish planet seen in this episode (a slightly color-corrected version of the one used in ), reappeared in later episodes, as Gamma II in , Arret in , in , Minara II in , Platonius in , Cheron in , and Gideon in .
* According to Walter Koenig, director Joseph Pevney wanted to shoot a close-up of Chekov's eyes as he sees the aged dead body in surprise. However, Koenig blinked each time it was tried, and it took fifteen takes to do it right. However, the close-up is not in the finished episode. Koenig also felt that Chekov seemed younger in this episode than in any other, claiming that his reaction upon discovering the corpse in the teaser was more like the reaction of a 15-year-old than that of a Starfleet officer who had sat on the bridge of the Enterprise. 
* In The World of Star Trek (3rd ed., p. 73), William Shatner relates that he endured an excruciating make-up session for this episode – all for nothing, because the shooting day was just about to end. The producers caught his exasperation in an infamous blooper, wherein he declares, "Robert H. Justman, I'm going home now… after spending three hours putting this [expletive deleted] make-up back on – and it's your fault!"
* One memorable outtake features Beverly Washburn getting stuck on a line, before blurting out, "I FEEL LIKE HELL!" 
* No special effects shots were filmed for this episode. The entire Romulan attack is created by using stock footage from and . Also, no actual Romulans appeared in this episode, in this season's only Romulan appearance. They would return one final time in the third season episode .
* The script called for the aged Kirk to run from sickbay to the bridge, and gradually grow younger until he arrived. (The Star Trek Compendium, p. 84) But as director Joseph Pevney told Allan Asherman in The Star Trek Interview Book (p. 197), the slow speech patterns and actions of the ageing Enterprise personnel were making the episode overrun. So Kirk's reverse ageing scenes were cut.
* The last shot of the episode is lifted from , which was evident from the wig Walter Koenig wore in that episode, which he didn't have on for the entire episode.
* The end credits of this episode include a makeup test shot of William Blackburn as a Tellarite. He discusses his experience in an interview on the remastered second season DVD collection of the series issued by Paramount and CBS Home Video.
* This is the first time Kelley is aged using makeup to look much older than he is. The second time is in .
=== Continuity ===
* Areel Shaw's line from about how long it has been since she's seen Kirk is recycled by Janet Wallace in this segment, with Wallace's time having been "six years, four months, and an odd number of days," while Shaw's was "four years, seven months, and an odd number of days."
* Kirk's age is given in this episode as 34.
* This episode also establishes that Sulu has served with Captain Kirk for two years. (c.f. )
* The proximity of the Gamma Hydra sector to the Romulan Neutral Zone in this episode is repeated in the opening scene of , when the Enterprise supposedly violates the zone while patrolling near the sector. However, in the movie, it is the Klingons who attack.
* Kirk makes a reference to the fictional "corbomite" device, which he first described in . Although Chekov was not on the bridge on that occasion, he and Sulu exchange knowing looks when Kirk mentions the word. It is speculated in The Star Trek Compendium (p. 86) that Chekov's familiarity with the bluff further reinforced his presence aboard the Enterprise during TOS Season 1, much like would place him aboard during . The Compendiums theory, however, would be refuted during the next episode, , when Chekov was oblivious of Mudd's visit in – the episode after "The Corbomite Maneuver". Be that as it may, the Compendiums other theory, "that Sulu had filled him [Chekov] in on what happened during that ["The Corbomite Maneuver"] adventure," seems more likely to be true, in spite of its own admission to the contrary.
* As he aged, McCoy's Southern dialect grew noticeably thicker as well as his "old country doctor" mannerisms. (The Star Trek Compendium, p. 83)
