“The Doomsday Machine“, unlike the previous episode “The Apple”, is an episode I know well merely from the title. The Enterprise encounters a terrifying and seemingly unstoppable planet destroying machine, with a hull made of solid neutronium and a horrible maw large enough to eat starships.

Much of the episode is a cat and mouse game of starship combat with this doomsday machine – a name given to it by Kirk when he speculates on its origin and purpose. Backtracking its path through destroyed systems, Spock concludes it has come from outside the Galaxy. Kirk surmises that such a destructive force could only be the ultimate weapon of a war of utter annihilation – a doomsday machine designed to destroy everything if its creators should lose. The parallels to the nuclear mutually assured destruction of the Cold War when this episode was made are obvious. But the episode doesn’t deliver a heavy-handed moral about this – it simply uses this set-up to drive a dramatic and compelling plot, with an Ahab-like rampage of revenge by the destitute Commodore Decker after he loses everyone on board his ship, the USS Constellation.

I think this is the first time we’ve seen another Constitution class starship in the series (I may be wrong, but I don’t recall one before now). Dramatically, it’s damaged, the result of a prior attack from the doomsday machine, and its distress call is the catalyst for the episode in the pre-credit scene. Uhura appears to be off-duty for the entire episode – her role is taken by a Lieutenant Palmer, who gets a lot of lines as there is a lot of communication between the Enterprise and Constellation, mixed up with a lot of subspace interference. Kirk, McCoy, Scotty, and an engineering crew beam over to the crippled Constellation to find out what happened. They find commanding officer Commodore Decker the only survivor, in shock after beaming his entire crew down to the third planet of the system for safety. When Kirk points out the system only has two planets, Decker wails, “I know! That thing destroyed the third planet!”

Scotty says the antimatter on the Constellation has been “deactivated” – I wonder how that is done – but he starts work on getting the impulse engines running. Meanwhile, McCoy escorts Decker back to the Enterprise, where Decker pulls rank on Spock and assumes command, ordering the ship into a revenge chase of the machine rather than going to pick up Kirk. McCoy objects and tries to declare Decker unfit for command, but Spock points out the regulations require a medical examination first, which he hasn’t had time to do.

Scotty gets the Constellation running and it interferes just in time to save the Enterprise from destruction by the machine. Kirk then orders Spock to relieve Decker of command, which he does so by pointing out that Decker is acting suicidally. Spock has Decker escorted off the bridge, but Decker manages to overcome the guard in a fistfight (why don’t they employ competent security personnel?) and steals a shuttlecraft (why don’t they have any security at all on the shuttle bay?). Decker flies the shuttle kamikaze into the machine’s maw, but the explosion barely affects it. However, the fact that it does have any effect at all gives Kirk the idea of doing the same with the wreck of the Constellation.

Spock estimates that blowing up the ship’s impulse engines will generate an explosion equivalent to 97.835 megatons. Scotty sets up a 30 second delay trigger, giving Kirk barely enough time to beam out safely (why didn’t he set up a longer trigger? Or a remote detonation mechanism so they could explode the ship from the safety of the Enterprise??). Thankfully the 30 seconds lasts about 2 minutes of screen time, giving Scotty enough time to repair the suddenly failing transporter and beam Kirk out at the last possible second.

Whew! It’s a whirlwind of edge-of-the-seat excitement. The plot is not overly complex, but it’s full of tension and keeps you glued to the screen. Definitely one of the classic episodes. And we’ll see Commodore Decker’s son appear later, in the first Star Trek movie.

“The Apple” is not one of the more memorable episodes. The title itself brought back no memories at all for me – it wasn’t until I got about 10 minutes in that I recognised what episode this is. Not a good sign.

Kirk, Spock, McCoy, Chekov, girl of the week Yeoman Martha Landon, and four redshirt security officers beam down to Gamma Trianguli VI, lush with tropical vegetation and a lurid red sky. Chekov compares it to the Garden of Eden, which was just outside Moscow. Chekov has other Eden-esque activities in mind, as we (and Kirk) notice that he and Yeoman Landon are more interested in each other than their duties. Spock says the village they detected from orbit is 17 kilometres away, so they start walking – a very long way to walk, given they have transporter technology that could have placed them right there. This lapse of reason is never explained.

As they set off, redshirt one bites the dust, thanks to being sprayed with poison darts from a lotus-like flower. Following this event, rather than beam back to the Enterprise, or beam down a botanist, or take any sort of precautions whatsoever, Kirk picks up the flower and sniffs it, and then they continue their slog through the jungle to the village. Spock finds a curious rock which he examines, snaps in two, then tosses aside – and it explodes on impact. Another flower takes aim at Kirk, and Spock pushes him aside but takes the full brunt of the darts. McCoy manages to revive Spock, thanks to his Vulcan physiology.

The party realises the Garden of Eden metaphor is strained to breaking point, and Kirk tries to beam everyone up, but it’s too late, as Scotty reports interference from an energy source located near the village. With nothing better to do, they keep walking. Redshirts two and three are annihilated when one is struck by lightning in a sudden storm, and another steps on an explosive rock. Kirk expresses his self-doubts in an emotional speech. Spock interrupts to mention that a native humanoid is lurking nearby.

Kirk intercepts the native and initiates a fistfight, but is taken aback when the native doesn’t fight back, but rather starts weeping and expressing puzzlement at being hit. Kirk reassures the native that he comes in peace. The native says he is Akuta, and is the “Eyes of Vaal”, and leads them to his village, which is populated by about two dozen people, with no children or elders. They are confused by the concepts of children and love. Vaal has forbidden them!

The natives take the crew to Vaal, which turns out to be a symbolically snake-like cave, where the natives leave offerings whenever Vaal calls. Spock decides Vaal is a machine, ruling the naïve villagers like a god. Spock and McCoy engage in a debate about whether Vaal needs to be stopped, and Kirk decides that yes, it does. But Vaal has also decided to get rid of them, telling the natives to attack the crew. Redshirt four goes down in the attack, but the crew best the rest of the villagers (including some well-aimed athletic kicks by Yeoman Landon) and then confine them to a hut. Vaal calls to be fed, but Chekov and Landon are enough to stop the villagers leaving. Kirk calls Scotty to phaser the snake-cave in its weakened state and this destroys it. They then tell the natives that life will be much better now, because they’ll be able to … um … make children now. They warp out of orbit, having interfered with another undeveloped alien civilisation.

Well, this is really a pretty weak and uninspiring episode. The multifarious allusions to the Garden of Eden are possibly the most interesting part. Vaal is a serpent, the villagers are innocent. Kirk even eats an apple conspicuously when they are resting in the village. The denouement even has Spock pointing out that Kirk has effectively played the part of Satan by metaphorically giving the villagers knowledge of good and evil. But ultimately you want some actual drama in the story, and some sensible decision making by the characters, neither of which are particularly in evidence here.

“Mirror, Mirror” is one of the all-time classic Star Trek episodes. It might feel clichéd and hackneyed now by comparison to all of its imitators, but this is really the one that started the evil mirror universe trope. And judged in those terms, it still comes up sparkling.

It begins with a landing party consisting of Kirk, McCoy, Scotty, and Uhura on the planet of the Halkans, attempting to negotiate for the Federation to purchase dilithium. The Halkans are the epitome of Perfect Pacifist People, however, and refuse to sell, fearing the Federation might use the dilithium for hostile purposes. Resigned to this diplomatic failure, the crew beam up in the middle of an ion storm, which causes a transporter malfunction. (Why do they beam up during an obviously unpredictable and dangerous ion storm?) They appear in the transporter room of a ship that looks like the Enterprise, but with strange symbols on the walls. Their uniforms have changed into more stylish variants, with glitzy bits and holstered daggers, including Uhura’s showing a wide strip of torso. And then they see Spock, who has a neatly trimmed goatee. (A cliché, you say? Yes, but a cliché started by this episode!)

Of course, they are in an evil mirror universe, and spend the rest of the episode trying to deal with this and figure out a way to get home without being killed by the evil Enterprise crew. It turns out that in this universe, the senior officers recruit henchmen from amongst the lesser ranks, and jostle for promotion by assassinating their superiors. Evil-Chekov tries this on Kirk, but Kirk’s henchmen protect him and Spock places Chekov in the agony booth. Evil-Sulu meanwhile flirts with Uhura, giving us a good look at his evil scar in the process.

With the help of the ship’s computer, which has a male voice in the evil universe, Kirk eventually figures out that they are in a mirror universe and instructs Scotty to start working on rewiring the transporter system to send them home. McCoy, with nothing else to do, joins Scotty reluctantly. (“I’m a doctor, not an engineer!“) Uhura’s mission is to distract Sulu from his security console while the power is rerouted, so he doesn’t see the warning light.

We learn that in this universe, the Federation is an evil Empire, and Kirk is ordered by Starfleet to annihilate the Halkans and take the dilithium. His reluctance to do so alerts Goatee-Spock that something is amiss, and Goatee-Spock does some detective work to figure things out. Eventually he corners McCoy and mind melds to read what’s going on. In a flash to the original universe, we see the evil Spock, McCoy, Scotty, and Uhura being dragged off to the brig. Evil-Kirk pulls some extraordinary facial expressions as he rages and offers Good-Spock “credits” in exchange for his freedom – another of the occasional references to money in Star Trek.

In a subplot, Kirk finds Evil-Lieutenant Marlena Moreau in his quarters, who is his “captain’s woman”. She unwittingly acts to fill Kirk in on various aspects of this universe, including the fact that Evil-Kirk has a mysterious alien artefact secreted in his quarters that can remotely make people simply vanish from reality. It turns out Evil-Kirk has used this device to rise to Captain by simply erasing all his enemies. The question arises of why doesn’t the good Kirk have one of these gizmos in the original universe; maybe he found it but promptly handed it over to a museum. Marlena uses the device later to save Kirk from three of Scar-Sulu’s thugs in another assassination attempt.

Eventually Kirk, Scotty, and Uhura gather in the transporter room, ready to beam back to their own universe, but McCoy has gone missing, and time is running out because the hole connecting the universes is closing. McCoy appears, in Goatee-Spock’s custody. Goatee-Spock, despite being coldly logical to the point of killing people, is not particularly evil as such, and has a conversation with Kirk before agreeing to beam them home and get his own Kirk back. Kirk suggests that Goatee-Spock use the alien device to off Evil-Kirk and lead a revolt against the Empire to establish a new order of peace, and Goatee-Spock says he’ll consider it.

When they get home, there is some banter with Spock about how the evil versions of themselves were easily detectable because it’s hard for barbarians to act civilised, while it was easy for the civilised good guys to act like barbarians. Kirk then spots the good-Marlena, who he’d never met before as she was only a recent assignee to the ship, and goes to flirt with her over the closing credits.

Whew. It’s a wild ride, and an episode that keeps you glued to the screen throughout. I remembered this one as being somewhat corny, presumably because of other interpretations of the now clichéd evil mirror universe thing, but watching it shows just how well done it was in this case. It still holds up really well, and is easily one of the more intense and compellingly dramatic episodes of the series. A definite winner!

“The Changeling” is the one I always remember as the episode version of the film Star Trek: The Motion Picture. The plot is essentially the same on the large scale, so much so that it seems odd that during the film Kirk and Spock never once mention their previous experiences from this episode.

The episode opens with the casual death of over 4 billion Malurians, when Kirk responds to a distress call from a Dr Manway (leader of a research team) and arrives only to find the entire Malurian system devoid of life. An unseen ship then starts shooting at the Enterprise, hitting it with incredibly powerful bursts of energy that threaten to overload the shields and destroy the ship. Kirk fires back futilely, then when all seems lost attempts to communicate. The mystery ship responds, and both parties establish they have no hostile intentions(!). Spock says the mystery ship is only a metre long, so they beam it directly on board the Enterprise to have a chat.

It soon becomes apparent that the “ship” is in fact a robotic space probe, which calls itself Nomad. Kirk gives it a bit of a tour of the ship, leaving it in engineering. It’s interesting how Kirk’s tendency to show off vital parts of his ship to mysterious aliens of unproven intentions was never picked up in Starfleet Academy psych profiles. Uhura calls Mr Singh in engineering for a report and Singh goes off to check something, leaving the line open. Uhura displays her singing talent again while she waits, which prompts Nomad to head up to the bridge. There Nomad asks the purpose of Uhura’s singing. She is stumped, and Nomad responds by hitting her with some sort of brain scan. Scotty tries to intervene, but Nomad zaps him. McCoy declares, “He’s dead, Jim.”

Kirk confronts Nomad over Uhura, who lies unconscious. Nomad refers to Uhura as a “biological unit”. Spock gallantly comes to Uhura’s defence, saying, “That unit is a woman.” Nomad’s response: “A mass of conflicting impulses.” Nomad then offers to repair Scotty. Kirk tells Nomad to follow McCoy to sick bay; we see this from an eerie and unusual hand-held camera angle just behind Nomad’s PoV. Nomad brings Scotty back to life as if nothing had happened, but says it can’t fix Uhura, whose mind has been wiped clean. Nurse Chapel begins retraining Uhura, beginning with basic reading skills.

Kirk questions Nomad more strongly. Nomad says it is programmed to sterilise all imperfect beings and declares that Kirk is the Creator, who created it. This confuses Kirk, who is about to deny it, until Spock, checking a library computer, interrupts and declares that Kirk is the Creator. Spock pulls Kirk away and explains that Nomad is an Earth probe built by a Dr Roykirk in the 21st century, and that it now thinks Kirk must be Roykirk. This could be the only thing preventing Nomad from sterilising the Enterprise of all life.

Spock wants to mind meld with Nomad to learn more, and Kirk orders Nomad to allow it. Spock learns that Nomad was damaged and melded with an alien probe, getting their programming mixed up in the process. Furthermore, Nomad is seeking its origin – i.e. Earth – and if it gets there will probably sterilise the planet! Kirk lets slip that he is an imperfect biological unit, and Nomad goes on a bit of a rampage, disintegrating a few redshirts on the way to engineering, where it disables life support. Scotty declares that without life support they can only last— and in an interesting twist on the usual formula is cut off before he can give an amount of time. Kirk corners Nomad and tells it that it has made a mistake in thinking he is its Creator, therefore Nomad itself is imperfect and must be sterilised. This locks Nomad into a logic bomb and it blows itself up – conveniently just after Scotty beams it into space.

In the denouement, we learn that Uhura is up to college level education and will be ready to resume her role as communications officer within a week – i.e. conveniently before the next episode.

And so to episode 2 of the second season, “Who Mourns For Adonais?” No, despite the fact that this episode deals with Greek gods, that’s not a typo for “Adonis“, it’s a reference to the poem Adonaïs, by Percy Bysshe Shelley.

It begins with the Enterprise surveying the Beta Geminorum system, belonging to the star otherwise known as Pollux, in a piece of well-placed real-world stellar cartography. Approaching Pollux IV, a huge disembodied hand made of some sort of energy field grabs the Enterprise and stops it dead in space. Then a disembodied head appears and cryptically invites Kirk and selected crew to beam down to his planet. Kirk declines and tries to get the ship away, but the hand squeezes the hull, causing Scotty to complain that the hull cannae take the pressure. Apparently putting pressure on the hull – but not enough to actually buckle it – also causes a painful increase in air pressure inside the ship, as everyone clutches their ears in pain while it occurs. The head specifically doesn’t invite Spock, who it says reminds him of Pan, with the pointed ears.

Kirk, McCoy, Scotty, Chekov, and Lieutenant Carolyn Palamas beam down. Palamas is the Archaeology and Anthropology officer. It seems they have specialists in everything on the Enterprise. Earlier we saw that Scotty has a soft spot for Carolyn, but McCoy doesn’t think it’ll go anywhere because currently Carolyn is dedicated to Starfleet. She may find a man outside Starfleet and leave the service, but won’t fall for a fellow officer.

They beam down to an idyllic area which has a small Greek temple in it. The owner of the disembodied head greets them, and introduces himself as Apollo, the god of the sun. He claims to have been on Earth 5000 years before, and has now been waiting for humanity to find him again.

In a strong echo of “The Squire of Gothos“, Apollo takes a shine to the girl of the week, Carolyn, and uses his nigh-omnipotent powers to put her into an alluringly flimsy dress and begin flirting with her, while keeping the men of the landing party at bay and preventing them from contacting the Enterprise. In another echo of that episode, Kirk deduces that Apollo has a power source somewhere and that perhaps they can trick Apollo into a moment of weakness and destroy it.

Meanwhile on the Enterprise, Spock is ordering people around, including instructing Uhura to rig a subspace bypass of the jammed radio circuits to contact Kirk. We see Uhura head deep in a console, soldering circuits, showing she is a practical, hands-on crew member. Which is good, except that her elaborate hairdo is getting in the way and is in serious danger of catching fire from the soldering iron.

Apollo displays some weakness when Scotty, protective of Carolyn, incurs Apollo’s wrath and Apollo unleashes lightning bolts on him. This weakens Apollo and he vanishes for a while. Chekov likens the disappearing act to that of the cat with the smile from a Russian fairy tale. When Kirk amusedly points out that it’s an English tale, with a Cheshire Cat, Chekov sincerely responds, “Cheshire? No, it was Minsk.”

There’s a bunch of padding to make up the 50 minutes of screen time, followed by the Enterprise breaking through the giant space hand and contacting Kirk. He orders phasers fired on the temple, which destroys it, to the impotent horror of Apollo. Kirk gives a Picard speech about humanity not needing gods any more – and goes on to say they get on fine with “just the one”. Apollo sheds tears and then vanishes, following the other Greek gods who have long since given up and spread themselves to the winds of the Universe.

The episode ends without resolving the romantic tension between Carolyn and Scotty, and of course we never see Carolyn again. A rather lame episode, with recycled plot elements and unsatisfactory loose ends, although there are a few moments of drama and interest to keep it from being appalling. Chalk up yet another semi-omnipotent being in the growing catalogue of beings encountered by the Enterprise, and bring on the next episode.
