Earthshock (TV story)

Earthshock was the sixth story of season 19 of Doctor Who. It was notable for its high ratings, the deliberately unannounced return of the Cybermen, and the death of Adric.

Indeed, this serial and Time-Flight together offered producer John Nathan-Turner his highest consistent chart positions. Earthshock was the only serial in JNT's producership whose episodes were all in the top fifty of programmes watched on British television.

JNT took a now-well-known publicity gamble with this serial by deciding that he wanted to keep the return of the Cybermen a surprise. Normally, there was a public gallery overlooking the studio floor at Television Centre which allowed public viewing of proceedings. For Earthshock, JNT had this area closed and security kept people out. Nathan-Turner also turned down a Radio Times photo shoot to ensure this secret.

The death of Adric was also a considerable gamble, since no long-running companion had ever been killed on Doctor Who before. Special, downbeat titles were commissioned for the end of part four, making the final part the only episode,, to have no end theme music.

While there is no doubt that JNT and his team absolutely intended Adric's unambiguous death, the ending of the story has been materially changed by Big Finish's The Boy That Time Forgot, during which it was revealed Adric did not die but went on to live in a bubble universe the Fifth Doctor accidentally created, before finally crossing back into the normal universe in Victorian London.

Synopsis
A conference to unite military powers against the Cybermen is taking place and the Cybermen plot to destroy the Earth by crashing a space freighter into it. The Doctor must stop them, whatever the cost...

Part one
Lieutenant Scott and his team climb up a bleak hillside on Earth, escorting Professor Kyle to a camp set up by Scott's team. The scanning equipment at the campsite is directed at a cave to detect mammalian life forms. Kyle had been part of a scientific expedition investigating the caves for fossil remains, but the expedition has disappeared. The lack of readings suggests they are all dead. Kyle's knowledge of the tunnels is necessary to direct Scott and his team into the caves to find out what happened, while two troopers remain outside to maintain a constant scan. As they investigate, the squad is being stalked by two dark figures.

Meanwhile, in the TARDIS, Adric begins arguing with the Fifth Doctor about the lack of attention and respect he receives compared to Tegan or Nyssa. Finally, he declares that he wishes to return to his home planet of Terradon, which the Doctor loudly proclaims is not possible, However, Adric is insistent that he can calculate the coordinates to guide the TARDIS back into E-Space; to the Doctor's displeasure, Adric begins to write down his calculations.

Scott's squad splits into two groups, but a strange jangling sound comes over the communications system, and one group ceases contact. Outside, a flare appears on the outside scanner. Walters and Snyder see more life-forms appear on the scanner — the TARDIS crew, which have just landed in the caves. However, Scott instantly assumes that the newcomers must be responsible for the deaths, especially when he is informed that one of the new life signs shows two heartbeats.

While Adric computes his calculations, the Doctor has gone for a walk in the caves. With Tegan and Nyssa, he examines the fossils of dinosaurs on the cave walls. musing that he had always wanted go back and determine exactly how they died. As the wounded party is making slow progress, Snyder goes in to help, but they are attacked by the dark figures. The jamming increases, and Snyder is reduced to a pile of smoking remains. As the survivors start to investigate, they continue to be picked off one by one.

Scott and the remainder of his squad come across the Doctor and his companions and capture them. Scott accuses the Doctor of the murders and, while the Doctor tries to convince him otherwise, the dark figures continue their approach. Digging away at a recent rockfall, they discover the remains of the scientists as well as a metal hatch which begins to emit a trilling sound; Scott orders the Doctor to open the hatch. The dark figures pick up their pace and begin to attack as everyone dives for cover.

The Doctor realises that the attackers are androids, which is why they did not show up on the scans. The androids appear to be defending the hatch and shrug off the troopers' counter-attacks. Kyle recognises the sound the androids are making, and realises that they were the ones who murdered the others. As an android focuses its gaze on the Doctor, the image is transmitted elsewhere to their masters: the Cybermen. The Cyber-Leader orders that the androids destroy them all...

Part two
Inside the TARDIS, a signal is detected. Adric wanders out of the TARDIS, trying to locate the Doctor and determine the source of the signal. He is able to distract one of the androids long enough for Scott and his team to destroy it. The other one is subjected to intense fire att, also resulting in its destruction. The Doctor has realised that the signal is being transmitted to whatever is inside the hatch. He runs back to the TARDIS and is able to jam the transmission. He and Adric return with the Doctor's tool kit. Tegan and Nyssa usher the rest back into the TARDIS where they will be safe as the Doctor and Adric open the hatch to discover an explosive device within. The Doctor fiddles around with the bomb and inadvertently reactivates it, but together with Adric disarms it before it detonates. Returning to the TARDIS, the Doctor informs the others that they are going to trace the source of the transmission. The Cybermen are puzzled as to why the bomb failed to detonate. Reviewing the recorded images transmitted by the androids, they see the TARDIS. They realise the Doctor is involved, and begin to review their past encounters with the Time Lord.

Meanwhile, out in space, a freighter is being inspected by Earth security forces while replenishing its supplies and crew. However, the morale of the crew is low, kept going only because of the promise of their bonus for delivering the cargo on time. Ringway, one of the bridge crew, wonders if the bonus is worth it, with several disappearances having already taken place. Berger seems to think that it is, and suggests Ringway adopt a more cheery attitude towards the crew to maintain their morale and his.

Having arrived on board, the Doctor and Adric explore the freighter, and come across the bodies of two dead security men. Ringway encounters them over the bodies and declares them murderers, the penalty for which is death.

Part three
Ringway escorts the two travellers to meet the freighter's captain, Briggs, a middle-aged woman who is only concerned about the bonus.

Scott and Kyle start to worry about the Doctor and Adric, although only Scott says anything. Scott announces that he wants to go find the Doctor, but Nyssa replies that the Doctor will not thank them for taking such a risk. Scott takes no notice. Tegan, also wishing to help, goes with Scott and his remaining soldiers.

The Cyber-Leader decides that it is time to take control of the freighter, and orders a unit of Cybermen to be activated. The unit marches on the bridge and is spotted on one of the monitors. Briggs orders a blockade set up outside the bridge, despite the Doctor pleading that her men won't stand a chance if they do that. Sure enough, the Cybermen effortlessly blast through the barricade. At the same time, Ringway turns on the crew and announces that he now works for the Cybermen, having grown tired of Briggs. The Doctor disarms him and closes the bridge doors before the Cybermen can get inside. Briggs seems confident that they can hold out until they get back to Earth, as there are only a few Cybermen; when Adric inquires as to how many cargo containers there are, she realises that all 15,000 are probably full of Cybermen. As Scott, Tegan and the others kill one Cyberman and damage a second, the Cyber-Leader has his troops soften one of the bridge doors with a thermal lance. The Doctor taps into the antimatter storage system and uses it to stabilise the door just as a Cyberman breaks through, with the result that the Cyberman is fused into the door. The Cyber-Leader had also fitted explosive charges to the other bridge door, however. Just before it goes to detonate them, the Cyberman that Tegan killed crawls up. His lieutenant points out that all the crew have been accounted for, and the Cyber-Leader erroneously concludes that Ringway lied about the crew numbers.

The explosives are detonated, destroying the bridge door. The Cybermen take the bridge, and the Leader has Ringway killed for his "deception". The Doctor then sourly jokes, "You never change; always the perfect guest". The Doctor and the crew members all watch as the additional Cybermen are revived, in order to deal with the other humans. As they march through the hold the Leader declares, "My army awakes, Doctor!"

Part four
The Cybermen fit a device to the ship's computer which locks it on course to collide with Earth. The Cyber-Leader then explains his mission - several galactic powers are going to meet on Earth that day and hold a conference that will unite them in a war against the Cybermen. Their original plan was to use the bomb to virtually destroy Earth, commandeer the freighter and use the army to kill anyone who survived. Due to the Doctor's interference, the Cyber-Leader has switched to his backup plan - crash the freighter into Earth. As it is powered by antimatter, the resulting blast will be every bit as devastating as the bomb would have been.

Tegan gets separated from Scott and his men and is eventually captured. Scott returns to the TARDIS, but is followed by a pair of Cybermen. The troopers kill the Cybermen and take their guns, but Kyle is killed in the process. Tegan, meanwhile, is taken to the bridge. Noting the Doctor's reaction when she is brought into the bridge, the Cybermen comments that emotions must be a severe handicap for the Doctor. The Doctor argues that emotions are what makes life worth living - in response, the Cyber-Leader orders that Tegan be killed. The Doctor throws himself in front of Tegan, and the Cyber-Leader remarks that emotions are a disadvantage, as now he only has to threaten to kill Tegan for the Doctor to obey him.

Scott and the troopers leave the TARDIS again, as the Cyber-Leader decides to leave the ship in the TARDIS. Briggs, Berger and Adric are left on-board so that a few remaining Cybermen can observe their reactions, and thus better understand human weaknesses. The Doctor and Cybermen leave in the TARDIS, and Scott takes out the Cybermen guarding the bridge. Briggs wants to abandon ship, but Adric tells her that he might be able to override the device controlling the ship's computer. He overrides one segment of it and Berger tries to bring the ship out of warp, but this has an unexpected effect - the freighter jumps into a time warp and goes backwards in time. Tegan is relieved at this, believing the Earth to be safe. Her relief is soon shattered when the Doctor points out that it has made the situation far worse - not only will Earth still be destroyed, but with the freighter now back in an earlier point of its history, the planet's whole existence will be nullified.

Adric overrides another part of the control device, bringing the freighter out of warp - but still perilously close to Earth. Briggs decides that it's time to abandon ship, but Adric is still determined to break the codes. Scott drags him into the escape pod, only for Adric to jump out at the last second and continue his efforts. Back on the TARDIS, the Doctor points out that they have travelled back 65 million years - at about the time the Earth collided with an object which killed the dinosaurs. Tegan realises that the object was really the freighter, and that rather than erasing Earth's history, the explosion will form a key part of it.

While Adric continues in his efforts, Scott signals the TARDIS and informs them that Adric's still on-board. The Cyber-Leader decides to kill the TARDIS crew, but Tegan jumps on him and the Doctor breaks up Adric's gold-plated Mathematics Achievement badge into the Leader's chest unit. The maddened and asphyxiating Leader fires its gun aimlessly, damaging the TARDIS console in the process. The Doctor grabs the gun and shoots the Leader, killing it. Adric is closing in on fully deactivating the control device, but is thwarted when a damaged Cyberman tries to shoot him. The shot misses Adric and destroys the freighter's controls instead, leaving no chance of altering the freighter's course. The Doctor tries to save Adric, while Nyssa quickly deals with the Cyber-Lieutenant. The TARDIS console is too damaged. The Doctor, Nyssa and Tegan watch helplessly as the freighter smashes into Earth with a massive explosion, killing Adric. As Nyssa and Tegan begin to weep, the Doctor remains silent, shocked at his failure in saving his companion and friend...

The episode ends with silent credits to mark Adric's death, rolled over an image of his shattered star-shaped badge.

Story notes

 * This story had a working title of Sentinel.
 * Producer John Nathan-Turner was keen to keep the return of the Cybermen a surprise, and thus ensured that this aspect was given no advance publicity — even going so far as to arrange for the studio observation galleries to be closed for the duration of recording and turning down Radio Times when they offered to feature the Cybermen in a cover photograph and article to mark the start of the story. The Cyber-Leader and Cyber-Lieutenant were referred to as simply 'Leader' and 'Lieutenant' in the combined Radio Times cast for Parts One/Two.
 * Adric's appearance in part two of Time-Flight is solely so he would be credited in the following week's issue of Radio Times, which would be published on the day part four of this story aired — thus hiding his death here.
 * This is one of the few serials in which the ending credits have been changed from the regular credits. Adric's star-shaped badge for mathematical excellence is shown broken in pieces while the credits roll in silence.
 * The multiple rows of marching Cybermen in part two were actually a single row duplicated and placed side by side using photographic editing.
 * The Cyberscope prop was built using parts the modelmaker had scavanged from the Nostromo set constructed for the movie Alien. Similarly, the digital readouts on the device flash up a random series of numbers which were also seen on the monitors of the Nostromo set.
 * One of the android costumes would later be repainted silver and used as the costume for the Raston Warrior Robot in The Five Doctors.
 * According to the research website BroaDWcast.org, there are reports that part four's silent credits were re-edited to include the regular theme music for its broadcast on the YTV network in the 1990s.
 * Part four is the first episode since The War Games to feature rolling credits. They would not be seen again until the 1996 television film.
 * The story was chosen by BBC America to represent the Peter Davison era during their 50th anniversary programming. Edited into an omnibus format, it was aired by BBCA on 26 May 2013, after the debut of their homegrown special called The Doctors Revisited - The Fifth Doctor. It also aired in the United Kingdom later in the year on 26 October, along with the Revisited special, on the Watch channel.
 * The reason for the Third Doctor's omission from the flashback clips was that he never encountered the Cybermen during his original tenure. In relation to this story, the Cybermen's encounter with the Sixth Doctor, (Attack of the Cybermen) in 1985 would have also been part of their chronological past as would be their 1988 encounter with the Seventh Doctor in Silver Nemesis. Neither were seen as part of the flashback clips. The real world reason for this, of course, was that although these events would have happened already in the timeline, these serials (with their respective Doctors) had not yet been created for the show.
 * This story also exists in the BBC archives as 2 x 50 minute compiled episodes broadcast as part of the Doctor Who and the Monsters repeat season in 1982.

Ratings

 * Part One - 9.1 million viewers
 * Part Two - 8.8 million viewers
 * Part Three - 9.8 million viewers
 * Part Four - 9.6 million viewers

Filming locations

 * Sprinwell Lock Quarry in Rickmansworth, Hertfordshire (This was the only location work, which featured at the start of the story, not featuring any of the regular cast)
 * BBC Television Centre (Studio 8), Shepherd's Bush, London

Production errors

 * Actor James Warwick changes Lt. Scott's accent without narrative cause. There's a clear and inexplicable difference between his work on location, and his later-recorded scenes in the studio. This fact was remarked upon by Janet Fielding and Peter Davison on the DVD commentary.
 * As Tegan complains that she's exhausted, something that looks like a stick is being waved around in the darkness. Then, as they climb the stairs on their way to the bridge, a person holding a script can be seen in the background. This fact, too, is highlighted by the DVD commentary.
 * When the Cybermen are marching the Doctor and Tegan back to the TARDIS, the lead Cyberman misses the bottom step and nearly falls. Peter Davison appears to be fighting back laughter while Janet Fielding appears to be resisting her urge to 'rescue' the clumsy Cyberman.
 * When the Cyberman breaks through the softened bridge door, the damage to the door and the Cyberman's arm change size and position between shots.
 * Just before the wounded Cyberman blasts the computer, Matthew Waterhouse pokes at the keyboard very gingerly, knowing it is about to explode.
 * When Scott returns to the TARDIS, he has two men and a woman with him. A Cyberman grabs the woman, but when they enter the TARDIS, the man is missing. Later, when they leave, the woman is gone again.
 * In part two, the Cyber Leader's finger misses a button on the console, but we still hear a beep anyway.
 * Near the end of this serial, Peter Davison must shove Adric's gold-laden badge into the Cyber Leader's chest from behind. Through the Cyberleader's face plate, a silver box can be seen pressing against David Banks' face. The Cyber costumes had radio microphones in them for recording so the modulation of the actor's voices could occur in real time. The batteries for these mikes were taped to the top inside of the actor's helmets. Over time, of course, the tape would work free and the batteries would fall out of place, resulting in the silver box seen in the Cyberleader's face plate for this scene. Also, when the Cyber Leader explodes, the wire attached to the small microphone can be clearly seen.
 * The dead crewmembers at the end of part two can be clearly seen breathing.
 * When Ringway is running down a corridor, supposedly in a tearing hurry, he visibly pulls up just before going out of shot.
 * Just before Tegan and the soldiers find the bodies in part three, a white baton mysteriously appears behind them — apparently placed there by a crew member.
 * The director commits a line-of-sight blocking error at the end of part one. When the Doctor is discussing the androids. Nyssa and Tegan are nowhere to be seen — yet from the android's view point they are right beside the Doctor.
 * When Lieutenant Scott is first walking up the stairs to reach the bridge on the freighter, a very small glimpse of an trainee production assistant can be seen in the background of the shot. She is wearing a white jacket and has a script in her hands, and can be seen turning a page of it. This was pointed out by Peter Davison on the DVD commentary.

Continuity

 * Adric mentions that Romana is still in E-Space, and could help him if he returned. (TV: Warrior's Gate)
 * Adric also states that he would not return to Alzarius, but rather to Terradon. (TV: Full Circle)
 * The Doctor uses Adric's gold star to asphyxiate the Cyber-Leader. Gold was first demonstrated as a weakness to Cybermen in TV: Revenge of the Cybermen, and Adric received his badge in TV: Full Circle.
 * The Cybermen watch scenes from other encounters with the First Doctor (TV: The Tenth Planet), the Second Doctor (TV: The Wheel in Space), and the Fourth Doctor (TV: Revenge of the Cybermen).
 * The alien computer the Cybermen used and the fate of the freighter and Adric are explored further in AUDIO: The Boy That Time Forgot.
 * Unknown to the Doctor, a future companion named Jack Harkness is, for reasons unknown, on Earth at the time of the freighter explosion, though Jack would believe the destruction of the dinosaurs was caused by a meteor hitting Earth. (TV: Fragments)
 * The Eleventh Doctor would obscurely mention Adric, Katarina and Sara Kingdom by telling Brian Williams that some companions "but not many, died". (TV: The Power of Three)
 * An alternative version of the Doctor was able to save Adric. (PROSE: So Vile a Sin)
 * The Fifth Doctor is reading Black Orchid before his argument with Adric. (TV: Black Orchid)
