Doctor Who/Recap/S19/E06 Earthshock

"Now I'll never know if I was right."

- --Adric

Otherwise known as "the serial in which Adric dies."

A bunch of people who look like they bought surplus helmets from Starship Troopers go into a cave system to find a bunch of palaeontologists who have gone missing. They're also followed by a pair of shadowy figures who look like people in costumes.

Meanwhile, in the TARDIS, the Doctor and Adric are having a really childish argument. Apparently, Adric wants to go back home to E-Space, but the Doctor thinks it's too dangerous as E-Space is... E-Space. Either way, the Doctor materializes the TARDIS on 26th century Earth in a cave system and goes out for a little sulk. Nyssa and Tegan join him, pointing out dinosaur fossils in the walls as they go. The Doctor, who's read ahead in the script, mentions that he's always wanted to know how those dinosaurs died out.

Back with the missing-palaeontologists plot: the troopers decide to split up into multiple groups and explore deeper into the cave system. They even pick up a few life signs - one of them with two heartbeats. The leader of this group naturally assumes that the owners of these strange life signs are responsible for the palaeontologists who went missing, but they don't have much time to act on this before they are, sadly, turned into sludge. The survivors, lead by a man named Scott, stumble across the Doctor and the TARDIS and immediately relate their problems... until, that is, they notice that the Doctor, Tegan and Nyssa make great suspects. Before either group can make their case, however, those shadowy figures attack: Androids! Androids commanded elsewhere in a distant location by... Cybermen!

Adric wanders out of the TARDIS and is nearly killed by one of the two Androids attacking everyone else, giving them a chance to take the Android out. The second one falls soon after, but the Doctor realizes that those who controlled the Androids were sending some sort of transmission to a hatch built into the cave. Opening the hatch, the Doctor is shocked to find a bomb has been set by whomever started this mess. Bravely, the Doctor takes the bomb out of its hiding place and fumbles around with it, luckily defusing the bomb before it can be activated. Ha ha, no. The Doctor actually activates the bomb with his fumblings and it takes the combined efforts of the Doctor and Adric together to turn the bomb back off again.

The Cybermen, for their part, finally put two (a TARDIS) and two (a man dressed oddly who meddles in their affairs) and get four (the Doctor). They start preparing for his inevitable meddling as well, but not before the Cyber-Leader decides to show the audience some footage of the First, Second and Fourth Doctors from some of their Cybermen-oriented adventures.

The Doctor, satisfied with his deeds in the cave, ushers Adric, Nyssa and Tegan (as well as a few surviving humans from the cave) into the TARDIS. He decides to go trace the signal sent by the Cybermen to the Androids and the TARDIS materializes upon a freighter ship out in space that's suffered many random murders aboard during their travels to Earth. Almost immediately after stepping out of the TARDIS, the Doctor and Adric stumble across two dead bodies. Of course, as is dramatically required, the living crew finds the Doctor and Adric standing over the bodies and blames them for the murders.

For some random reason, the Cyber-Leader chooses now to take over the freighter, and activates a unit of Cybermen. They begin to stomp all over the ship as the Doctor and Adric are taken to the Captain, a middle-aged woman named Briggs who has the rare talent of sounding eternally drunk. One of the Cybermen bumbles onto the bridge and is instantly killed, only for the security chief to conveniently declare he's a double-agent for them. The Doctor and Briggs barricade the bridge by shutting the doors and Captain Briggs at first seems confident that they can survive to Earth...

...until she realizes that there must be around 15,000 Cybermen on the ship, hiding in her ship's cargo. Well, shit.

Meanwhile, the people stuck in the TARDIS decide to go see what happened to the Doctor and Adric, only to find a few Cybermen running around. Much hiding and stealth ensues. Back on the bridge, the Cybermen nearly break through by melting one of the doors... until the Doctor manages to re-solidify said door around a lone Cyberman in a pretty neat scene. Of course, the Cybermen just blow up the other door and take the bridge anyhow. Bragging, the Cyber-Leader activates all the remaining Cybermen on the ship, proudly announcing how he's won the day - but not before killing off the security chief. Because he could.

Finally, the Cyber-Leader announces his plan, which is so vast that it requires about 15,000 Cyber units. There is a massive meeting of governments that will unite all those peoples against the Cybermen. So the Cybermen have decided to break up the meeting, which makes sense. Turns out that little shoebox-sized bomb the Doctor deactivated in the caves was powerful enough to destroy everyone and everything on the planet's surface, proving that the Cybermen firmly believe that There Is No Kill Like Overkill. The Doctor thwarted their attempt to detonate the bomb, but the Cyber-Leader has a contingency plan -- crash the freighter into Earth, and the explosion of its antimatter-fuelled reactor will have basically the same result.

Regardless, Tegan is captured and dragged to the bridge while Scott and a few other humans run around blowing up Cybermen... but spending most of their time hiding from them. The Doctor makes a show of bravado until Tegan is threatened, and the Cyber-Leader claims that this is the weakness of organics. The Doctor claims otherwise, wondering when the Cybermen enjoyed the laughter of a child or sat down to have a nice meal together. The Cyber-Leader also heads out to the TARDIS to make his escape with a few other Cybermen. At this time, Scott's Commandos break onto the Bridge and pretty much slaughter most of the Cybermen there. Unfortunately, the ship's hyperdrive is damaged, sending the freighter careening back in time, meaning that the Earth of the future may be safe but the Earth of the past (and thus, all future) is now in danger.

Adric decides to stay at the control console, trying to fix the problem before everyone dies. Scott's Commandos and Captain Briggs instead leap out into escape pods, while the Doctor and the two ladies head out to recapture the TARDIS from the Cybermen. Inside the TARDIS, the Cyber-Leader holds the Doctor and companions at gunpoint while they... talk. For a good length of time. The Cyber-Leader brags about how Earth will be wiped out, but the Doctor then realizes that they've gone back in time just over 65 million years. This means that the dinosaurs were wiped out by the freighter/bomb combination rather than any meteor or asteroid... but no one remembers to tell Adric this, and he is feverishly crunching numbers in an attempt to stop the ship!

Fed up with the talking, Tegan jumps on the Cyber-Leader and fiercely attacks him by... hugging him from behind. The Doctor then shoves Adric's golden badge all up in the Leader's face, suffocating it with its weakness, but not before it shoots and damages the TARDIS console. And then the Doctor shoots him repeatedly in the chest anyway for good measure. Adric, for his part, is nearly done screwing up history when a lone, near-death Cyberman prevents Adric by blowing up the console. The Doctor excuses as to why he can't save Adric, and we watch Adric's ship ram itself into the surface of the Earth, killing off all the Dinosaurs and making way for Man... with Adric along for the ride.

Tropes
"Compared to some, this one is positively flippant."
 * Action Girl: Against all expections, Nyssa is the one who guns down the Cyber Leader's second-in-command at the end of the story. Tegan tries and fails miserably at this trope, only managing to get lost in the freighter's hold and getting captured by the Cybermen.
 * Plus at least a third of the soldiers are female, instead of the usual token female guest star amongst an all-male battalion.
 * Artistic License Biology: Dinosaurs are described as a "species". As in, just one.
 * BBC Quarry: One of the few serials of Doctor Who to feature a quarry that the Doctor and companions never visit.
 * The Corpse Stops Here: at the Doctor's and Adric's feet.
 * Creepy Monotone: Played straight (sort of), but ONLY by the regular Cybers. The Leader sounds, er... very emotional at some bits.
 * A Day in The Limelight: Each of The Doctor's companions was given a story where they could take a bigger role this season. This is Adric's. He gets the heroic sacrifice, the first since Katarina and Sara Kingdom back in season three.
 * Flanderization: In the olden days, the Cybermen didn't have a specific weakness to gold. Their inner mechanisms were simply clogged by dust, and since gold doesn't corrode it was tougher for them to flush out of their systems. Any dust thick enough would've done the job--lead dust would have worked just as well, and been cheaper too. But by the time this serial rolled around, gold itself acted on them pretty much like Kryptonite.
 * Flash Back: The Cyberleader gives his lieutenant a brief history of their encounters with the Doctor. Clips from "The Tenth Planet", "The Wheel in Space" and "Revenge of the Cybermen" are shown, though the Cyberleader mentions the events depicted in "Tomb of the Cybermen" rather than Wheel.
 * Ham to Ham Combat: Whenever the 1980s version of the Cyber Leader is involved, expect wall-to-wall scene chewing from at least one other actor. Such as Peter Davison in this serial, who tries to out-ham his enemy with all he can muster.
 * It Was His Sled: The fact that the Cybermen were the villains of the story was a twist they went great lengths to hide until the cliffhanger of the first episode (See Trailers Always Spoil below). At the time it was highly unexpected since the Cybermen had not appeared in the series for seven years. Today it is widely known; a Cyberman is even featured on the DVD cover.
 * Large Ham: The Cyber Leader, of all people. "My army awaits, DOCTORRR!" Throughout the episode, he displays anger, pride, irritation, even malicious smugness. It's even Lampshaded by the Doctor:

"Excellent!"
 * Even a single word sentence from the Cyber Leader becomes hamtastic, thanks to how it's read out each and every single time.


 * Let's Split Up Gang: Repeat after me, Doctor Who extras: Never Split the Party. Never Split the Party. Never Split the Party.
 * Missing Episode: The reason for the story mismatch in the flashbacks is that The Tomb of the Cybermen had yet to turn up.
 * Silent Credits: At the end of the last episode.
 * Trailers Always Spoil: Averted to truly heroic levels. The show's producer went to enormous lengths to keep the Cybermen's return secret, resulting in a famous Oh Crap moment when Episode 2 aired.

This is such a hard aversion that producer John Nathan-Turner actually avoided getting a cover shoot on the Radio Times in order to keep the secret as secret as possible, also insisted the cast listings in the same magazine simply referred to the Cybermen with speaking parts as "Alien Leader", "Alien Lieutenant", etc.
 * Weaksauce Weakness: The gold. See 'Flanderization.'
 * Wham Episode: Companion death has always been very rare. "Earthshock" intensified the effect by silently rolling the credits over a picture of Adric's badge, smashed beyond repair. While that's the biggest WHAM part of the episode it also has further value: Back when it first aired, the Cybermen being the villains was a well kept secret which also adds to the shock value. But both twists have suffered It Was His Sled at this point.
 * You Have Outlived Your Usefulness: Amusingly subverted. It appears that the Cybermen initially intend to honour their deal with Ringway, but when Scott's troopers arrive on the freighter and start shooting up the place, the Cyber-Leader wrongly assumes that these are extra crewmembers who Ringway was trying to hide the existence of, and kills him at the next opportunity.
