The Invasion (TV story)

The Invasion was the third story of Season 6 of Doctor Who. It featured the Cybermen in what became their established form for the next two decades. The Invasion also featured the second appearance of the Brigadier and formally introduced the organization known as UNIT and the character of Corporal (later Sergeant) Benton. Behind the scenes, it was the formal start of Terrance Dicks' record-setting tenure as script editor.

Synopsis
Escaping from the Land of Fiction, the Doctor, Jamie, and Zoe find themselves on 20th-century Earth, where they assist Brigadier Lethbridge-Stewart and UNIT in their investigations of the suspicious operations of industrial leader Tobias Vaughn. They soon learn that Vaughn is working with an old enemy of the Doctor's in their plan to invade and conquer Earth.

Episode One
The TARDIS materialises in space over the dark side of Earth's Moon, and is promptly fired upon by a missile from an unknown spaceship. The Doctor rushes to affect an emergency relocation out of the missile's path. After rematerialising, the Doctor, Jamie and Zoe find they have arrived in the late 20th century just outside London. However the TARDIS's visual stabiliser has become damaged, rendering it invisible. In order to have it repaired, they set out to find Professor Travers and ask for his assistance. When they arrive, they find that he has left for America, leaving his home in the care of Isobel Watkins and her professor uncle (also called Watkins). She explains that the Professor (Watkins) has disappeared, after he worked on an invention for International Electromatics. The Doctor and Jamie go to IE's head office in London to investigate.

When the computerised receptionist won't let them past, they seek out another point of entry; this leads them to being gassed and taken by security chief Packer to see IE's Managing Director, Tobias Vaughn. He apologises for the rough treatment the companions have endured, and explains that Professor Watkins was engrossed in a delicate stage of his worked and agreed to remain on site, — a statement which has piqued the Doctor's suspicions. After they leave, Vaughn opens a hidden panel in the wall of his office, revealing an alien machine. A decidedly inhuman voice speaking through the machine tells him that the Doctor and Jamie have been recognised from Planet 14, and are a threat to their plans.

Episode Two
The Doctor and Jamie are abducted by two men, later revealed to be Corporal Benton and Tracy, and taken to a EC-130H Hercules transporter plane, housing a complete operations room, where they are met by the Brigadier. He explains about UNIT, and the taskforce's investigation of IE.

Concerned about their failure to return, Zoe and Isobel leave for IE in search for them. They also encounter the receptionist, but, instead of seeking another method of entry like Jamie and the Doctor, Zoe destroys the computer by assigning it an insoluble equation in ALGOL, causing its circuits to overload. Vaughn is watching and orders Zoe and Isobel brought to him. Isobel is used to make her uncle, who is being held captive, co-operate.

The Doctor and Jamie return to Travers' house, to find a note from Zoe and Isobel, explaining their going to search for them. They return to IE, and find several packing cases being loaded onto a train. Part of a feather boa Isobel gave to Zoe is hanging out of one of the boxes, alerting the Doctor and Jamie to the fact that their friend is inside. But before they can rescue Zoe and Isobel, the Doctor and Jamie are again captured by Packer.

Episode Three
The Doctor and Jamie are taken to Vaughn, where the Doctor accuses him of kidnapping Zoe and Isobel, - a claim Vaughn flatly denies. Vaughn invites the two companions to come to the company's country compound, where the train will be arriving; it is here where they meet Professor Watkins, who has been warned to not mention Zoe and Isobel's whereabouts. He shows the Doctor his cerebration mentor, a teaching device that is capable of inducing emotional changes.

The Doctor queries Vaughn of the deep space communicator he noticed when he came into the compound; in return, Vaughn demands that the Doctor explain about the failed visual stabiliser, even threatening to hand Zoe to Packer if he doesn't co-operate.

The Doctor and Jamie escape onto a railway siding. Whilst in the crates, Jamie has a near encounter with an automated cocoon.

Episode Four
The Doctor and Jamie emerge from the crates, and overhear guards being ordered to take Zoe and Isobel to the tenth floor.

Vaughn confides in Packer that he intends to use the cerebration mentor to control the Cybermen once they have invaded Earth; he also intends to use the TARDIS as a "getaway car", should he fail.

Vaughn broadcasts over the intercom system to the Doctor that he has ten minutes to surrender or Zoe will be harmed. Using a communicator given him by the Brigadier, the Doctor calls for assistance from UNIT, who assist in rescuing Zoe and Isobel from the room in which they are locked. Realising how dangerous UNIT are to his plans, Vaughn exercises hypnotic control over Major General Rutlidge, and orders him to cease UNIT's investigations.

The Doctor examines photographs of UFOs over the IE factory, and reasons that those ships are bringing cocoons to Earth. He, along with Jamie, sneak into the London IE warehouse, where they witness the emergence of a Cyberman from its cocoon.

Episode Five
After witnessing the reactivation of the Cyberman, the Doctor and Jamie sneak back out of the IE warehouse. They return to UNIT HQ and warn the Brigadier that a Cyberman army are invading Earth, and that they are hidden somewhere in London. However, Rutlidge has ordered the Brigadier to cease all investigations against IE. Lethbridge-Stewart intends to gain authority from Geneva, but requires proof to back his reasoning. Isobel offers her expertise as a photographer, but the Brigadier refuses.

Vaughn tests Watkins' device on an awakened Cyberman; however, the alien is driven mad by the machine, and escapes into the sewers. Vaughn reveals that in an hour's time, the Earth will come under the control of the Cybermen through a micromonolithic circuit built into every IE device; the Doctor discovers this same circuit when he opens up an IE radio, and sets about making a device to block the telepathic signal.

Meanwhile, Isobel, Zoe and Jamie have ventured into the sewers to obtain proof of the Cybermen's presence on Earth. There they encounter the insane Cyberman, which kills a police officer who has followed them down into the sewer, then begins menacingly approaching the intrepid trio.

Episode Six
Isobel, Zoe, and Jamie narrowly escape from the sewers, but not before Isobel has managed to snap some photos of the Cyberman. The photos, however, prove to be worthless as they look too much like fakes.

Watkins perfects his machine and delivers it to Vaughn, but discovers that the Managing Director has been partially cyberrised. UNIT manage to free Watkins from IE, during which time the Doctor creates a neurister, which neutralises the Cybermens' hypnotic signals. The Brigadier orders all the troops to have one of these taped to the back of each one's neck. At dawn, the signal is broadcast, causing people around the world to collapse unconscious; leaving the Cybermen able to take over London.

Episode Seven
UNIT plan to use a Russian rocket to destroy the source of Vaughn's signal, while using UK missiles to destroy the incoming Cyberfleet. Captain Turner is sent to Russia to organise the rocket, while the Brigadier goes to the Henlow Downs missile site. The Doctor stays behind to try and dissuade Vaughn one last time to help hid people. The missiles are successfully launched, with help from Zoe, and the Cybermen blame Vaughn for the setback in their plans, announcing that they will use a megatron bomb to destroy life on Earth.

Episode Eight
Furious, Vaughn uses the cerebration mentor to destroy the machine in his office.

The Doctor persuades Vaughn to now aid humanity instead of trying to defeat it, and they take a helicopter to the factory, where they use Watkins' machine to battle the massed army of Cybermen; UNIT forces arrive later to assist. Vaughn is killed in the skirmish, but the homing signal is successfully shut down. The megatron bomb is destroyed by a missile, while the rocket destroys the last Cyberman ship, consequently stopping the hypnotic signal.

With the crisis now over, and the visual stabiliser circuits now repaired, the Doctor, Zoe and Jamie leave in the TARDIS.

Story Notes

 * This story had a working title of; Return of the Cybermen.
 * This story marked the debut of Terrance Dicks as the series' script editor, and his first credited contribution to the series. Dicks would go on to write or co-write a number of episodes, and become best known for his work as a Doctor Who novelist, adapting many serials for Target Books and eventually contributing to most lines of original fiction based upon the series. His contributions to the franchise and the preservation of its history has continued into 2008.
 * Together with The Web of Fear, this story set the stage for the "UNIT Era" of Doctor Who, which began with the following season. Plans were already being made at the time to incorporate UNIT in future stories.


 * While the Cybermen would continue to change their appearance on the series, as they had done since their introduction, this story set the basic design for them, first developed for this story by Bobi Bartlett, through the 1980s. Cybermen emerging from cocoons was also used in Earthshock. They also operate in the London sewers in "Attack of the Cybermen." A mass invasion of London by Cybermen also features in the Series 2 stories, Rise of the Cybermen, The Age of Steel, Army of Ghosts, and "Doomsday," and earlier Cybermen from the future had invaded Earth (The Flood).


 * This story was initially intended for four parts, but then expanded to eight after plans for what was to be the next story, the unproduced, The Dreamspinner, fell through.


 * Cybermats were to appear in this story, but later were written out.


 * It was during filming of this story that Frazer Hines announced his intention to leave the series.


 * Zoe makes no appearance in Episode Four of the story as Wendy Padbury was on holiday during the week when it was recorded.
 * Similarly Jamie appears only in a pre-filmed insert in Episode Eight as Frazer Hines was due for a break.

Influences
The influence of the various spy thriller films and television shows which were popular at this time are very clear. UNIT is in many ways similar to SHADO, the Earth security organisation in Gerry Anderson's UFO which premiered the same year as this story. (And elements of which were incorporated in the BBC Past Doctor Adventures novel, The Indestructible Man.) Tobias Vaughn is similar to villains featured in the James Bond films and The Avengers. The Doctor acting as advisor to a military group dealing with an otherworldly menace is highly reminiscent of the Quatermass serials.

 * Additional scenes at IE were filmed at the Guinness Factory in London.
 * The canoe sequence was filmed at Lisson Grove and the helicopter sequence at Denham Aerodrome in Buckinghamshire.
 * Other scenes were filmed at various locations in Gloucestershire.

Discontinuity, Plot Holes, Errors

 * In the animated version of episode 1, 'Bad Wolf' (the story arc of the 2005 series) is written on Isobelle's wall where she writes phone numbers. However 'Bad Wolf' was a message for Rose, so why was it written on Isobelle's wall? (It's an in-joke, and not present in the origonal - don't take it too seriously.)
 * In episode five, the panel concealing the Cyber Director struggles to close.
 * The Cyberman falling from the roof of an IE building in episode eight is clearly an empty costume.
 * Why does Vaughn continue to delegate tasks to Packer, who is obviously incompetent?
 * In episode 8, the strings that make the Cyber Director's 'head' twist are clearly visible.
 * The shots of the missiles being prepared are quite obviously the same bits of stock footage.
 * What happens to all the Cybermen that come out the sewers? The Doctor and UNIT only seem to stop the Cybermen deliver there bomb, and the Cybermen who have invaded are unaccounted for.
 * In addition to the above, what do the Cybermen actually do after they have invaded? They are not really seen after the episode 6 cliffhanger, and characters seem to be able to move about without meeting them.
 * Zoe and Isobel wait to be captured in episode 2.
 * In episode 4, the Doctor and his companions claim to have seen a ship on the moon - when they didn't (the animators added a ship to cover this up)

Continuity

 * Dialogue places this story four years after the events of The Web of Fear. This story is also placed "some months" before Spearhead from Space by dialogue in that story.
 * In Dalek, Henry van Statten's collection of alien artefacts includes the head of a Cyberman from this story, although its physical appearance matches that of a post Cyber Wars cyberman, as seen in Revenge of the Cybermen


 * The prologue of NA: Iceberg opens during the Cybermen invasion in this story. The Cybermen in that novel are said to be from Planet 14, which was first mentioned in this story.


 * Tobias Vaughn returns in NA: Original Sin, in which it is revealed that not only did he survive by transferring his mind into a cybernetic body, but funded the development of BOSS, Operation Golden Age, and Professor J.P. Kettlewell's robot, and influenced the expansion and policies of the Earth Empire.


 * The Doctor visits Planet 14 in DWM: The World Shapers.


 * The humorous touch of the TARDIS materialising in a cow pasture was also used in Image of the Fendahl.


 * A similar opening storyline of the Cybermen is seen in (DW: Rise of the Cybermen).
