Logopolis (TV story)

From Tardis Wiki, the free Doctor Who reference
More actions

Logopolis was the seventh and final story of Season 18 of Doctor Who. It was Tom Baker's last story as the Doctor and marks the first appearance of Peter Davison in the role, at the very end of the story. This serial also marks the first appearance of Janet Fielding as new companion Tegan Jovanka. After being introduced in the previous serial, Nyssa, played by Sarah Sutton, also becomes an official companion. This is also Anthony Ainley's first full story as the Master.


It's the end... but the moment has been prepared for.The Doctor

Synopsis

The Doctor goes to Logopolis to repair the TARDIS's chameleon circuit, but his old enemy the Master has plans of his own for the planet of mathematicians, a plan that could spell doom for the universe.

Plot

Part One

File:Logopolis part1.JPG
The Watcher - but what does he represent?

A policeman is talking from the telephone of a police box, (which is the Master's TARDIS in disguise.) Suddenly, the phone goes dead, and the policeman goes to the police box. A hand then drags him inside, and there is an evil chuckle. The Doctor is pacing around in the TARDIS Cloister Room, pondering thoughts of decay and entropy. As he and Adric prepare to leave, the large bell in the centre of the room begins to ring. This worries the Doctor, as the sound of the Cloister Bell is a sign of impending universal catastrophe.

To keep his mind off this, he decides to repair the TARDIS's chameleon circuit, which has frozen it into the shape of a police box. In order to do this, he intends to materialise the TARDIS around a real police box (thus disguising it), and then obtain its precise measurements in 27 dimensions. With these measurements, he will have the inhabitants of the planet Logopolis produce a mathematical calculation — a Block Transfer Computation — to reset the circuit. However, the "police box" he materialises around is actually the TARDIS of the Master, who has survived their encounter on the planet Traken. When the Doctor materialises around the Master's TARDIS, a recursive loop of TARDISes within TARDISes is formed.

Meanwhile, an airline stewardess, Tegan Jovanka, is being driven to the airport by her Aunt Vanessa. After their car breaks down, Tegan decides to go to the "police box" for help, but finds herself lost in the TARDIS instead. The Doctor and Adric enter another police box in a duplicate TARDIS, but the Doctor, telling Adric to wait behind finds himself this time outside the box. He meets a number of policemen, who find the shrunken, dead bodies of Tegan's aunt and the policeman.

Part Two

Tegan lost in the TARDIS

The police think the Doctor has something to do with it, but Adric creates a distraction, and allows the Doctor to escape. In the distance, a mysterious white-clad stranger watches the proceedings. Realising that the shrunken bodies are the trademark of the Master, the Doctor decides to materialise the TARDIS underwater, to literally flush him out. The Doctor misses the River Thames, however, and lands on a boat instead. The mysterious stranger appears here too, and beckons to the Doctor, telling him to go to Logopolis.

As the TARDIS arrives at Logopolis, Tegan finds her way to the control room, somewhat annoyed. She asks to know where her aunt is, and the Doctor, realising that Tegan's aunt was the dead woman in the car, skirts the question. Once they exit the TARDIS, the Doctor asks the Logopolitan leader, the Monitor, for his help. The Logopolitans are able to model reality by pure mathematics and whatever they calculate can take physical form. Since block transfer computations cannot be calculated by machines or computers, the Logopolitans speak aloud a line of calculations and passing them on.

However, unknown to the group, the Master has arrived on Logopolis, and has killed several Logopolitans, which disrupts the calculations for the TARDIS. When the Logopolitans produce the required computation and the Doctor attempts to enter it into the TARDIS, it instead shrinks the TARDIS to half its normal size and causes strange effects inside the ship.

Part Three

 
"Nothing like this has ever happened to me before...!"

The Logopolitans try to stabilise the TARDIS using sonic projectors to project a stasis field while the Monitor and Adric attempt to uncover the fault. Meanwhile, Nyssa has been brought from Traken by the Watcher, the mysterious white figure the Doctor spoke with. She is searching for her father. The Monitor and Adric work through the city and discover the shrunken bodies of three Logopolitans. Correcting the error this has caused, they bring the new computation to the TARDIS. Tegan holds the notes up to the TARDIS so the Doctor is able to read them through the scanner and correct the fault. The Doctor emerges from the now restored TARDIS, and admits to Tegan that her aunt is dead. Meanwhile, Nyssa finds the Master, whom she believes to be her

 
Nyssa discovers the Master killed her father, Tremas

father as he is inhabiting Tremas's body. The Master gives her a bracelet, which is actually a device which will allow him to control her actions.

The Master attaches a device to the sonic projectors and sets up a counterwave that brings silence to the Central Registry, preventing the Registers from making their calculations. He then goes to the Registry's control room (a replica of the Pharos Project on Earth, a radio telescope tasked to seek out signs of extraterrestrial life), and demands that the Monitor tell him what the true purpose of Logopolis is. The Doctor arrives with Adric and Nyssa, and Adric deactivates the Master's device, only for the Master to have Nyssa attempt to throttle him. Tegan restores the device, and the Master repeats his demand. The Monitor warns the Master that bringing Logopolis to a halt will cause universal disaster, but the Master replies that it is only a temporary effect, which he attempts to demonstrate by deactivating the suppression device.

However, the silence persists and the calculations do not resume. They go outside, and find all the Logopolitans dead, crumbling to dust, and the city itself collapsing. The Master thinks this is some sort of trick and tries to have Nyssa strangle the Monitor, but the control device ceases to function. He tries to increase the device's power, but this causes it to fall apart as local decay increases. The Monitor explains the situation: the universe had long ago passed the point of heat death. To stave off final collapse, the Logopolitans had been modelling a number of temporary Charged Vacuum Emboitments, like the one through which the TARDIS had been previously transported into E-Space. The excess entropy generated by the universe had been passing through the CVEs to other universes. However, the Master's interference has caused the CVEs to close and the universe is now dying at last.

Part Four

File:Logopolis part4.JPG
Final moments of the Fourth Doctor

Realising that he and the Master must work together, the Doctor orders his companions into his TARDIS, and has the Watcher take them out of spacetime. However, Tegan refuses to co-operate and follows the Doctor, Master and Monitor back to the Logopolis control room. The Monitor reveals that they had been completing a program to make the CVEs permanent, and prepares to use it on one of the surviving CVEs, but entropy takes hold of him and he disintegrates before their eyes. The Doctor dismantles the computer and realises the program is stored in bubble memory that they can use with the real Pharos Project. The Doctor, Master and Tegan escape from Logopolis in the Master's TARDIS.

Adric and Nyssa watch helplessly in the Doctor's TARDIS as a portion of the universe is wiped out by encroaching entropy — including Traken. On Earth, the two Time Lords reconfigure the Logopolitan program and feed it into the Project's computers, but the Master points out that the transmitter is pointed away from the last surviving CVE. After speaking with the Watcher, Adric brings the Doctor's TARDIS to Earth as the Doctor and the Master run on foot to realign the dish. The Doctor's companions distract the guards and the two Time Lords get to the dish's control room, hooking up a light speed overdrive from the Master's TARDIS to ensure the signal gets to the CVE in time. Upon transmission of the program, the CVE begins stabilising.

The Master's co-operation with the Doctor has been a ploy, however. Holding the Doctor at gunpoint with his Tissue Compression Eliminator, he transmits a message to the peoples of the universe, saying that if they do not acknowledge his rule, he will send a signal to close the CVE and restart the collapse. The Doctor climbs onto the radio telescope's gantry to disconnect the power cable, and the Master attempts to prevent him by tilting the dish 90 degrees. The Doctor succeeds in disconnecting the cable, but falls off the gantry. As he hangs on to the disconnected cable, visions of old enemies mock him.(The Decaying Master, A Dalek ,The Captain, The Cyberleader, Davros, A Sontaran, A Zygon and The Black Gurdian). Losing his grip, the Doctor plunges to the ground. The Master enters his own TARDIS and it dematerialises.

The Doctor's companions run to the spot where he has fallen. Dying, the Doctor experiences visions of the companions that have accompanied his current form (Sarah Jane Smith, Harry Sullivan, The Brigadier Alister Gordon Lethbridge Stewart, Leela,K9 Mark 1 ,K9 Mark 2 and Romana 1 and Romana 2 ) and then observes, "It's the end... but the moment has been prepared for." They turn to see the Watcher approach, and as he does so he merges with the Doctor. Nyssa realises that the Watcher was the future Doctor all the time. As the companions look on, the Fourth Doctor regenerates into a new, younger body — the Fifth Doctor.

References

  • The exact nature of the information given to the Doctor and, later, Adric in unheard conversation with The Watcher is never revealed.
  • The Logopolitans are vital to the stability of the Universe. They discovered long ago that the Universe had passed the natural point of total collapse and so used block transfer computation to create Charged Vacuum Emboitments into other universes.
  • The entropy field caused by the destruction of Logopolis also destroys a portion of the universe; Traken and Mettula Orionsis (Traken's star) are mentioned.
  • The Doctor's transmission of the Logopolis program saves the rest of the Universe, starting with the constellation of Cassiopeia.
  • On Logopolis, sonic projectors are said to "create a temporary zone of stasis". The mathematics of block transfer computation is a way of modelling space/time events through pure calculation

TARDISes

  • The TARDIS cloisters are seen for the first time.
  • The Cloister Bell is described as 'a sort of communication device reserved for wild catastrophes and sudden calls to man the battle stations'.
  • The Doctor states that the TARDIS was in Gallifrey for repairs when he 'borrowed' her. "There were rather pressing reasons at the time"
  • There are references to the TARDIS' faulty chameleon circuit and a demonstration of how it could function.
  • After picking up Adric and Nyssa, the Watcher disconnects 'the entire co-ordinate sub-system' of the Doctor's TARDIS, which takes it "out of time and space".
  • The Master's TARDIS disguises itself as a police box, a tree and an Ionic column at various times.
  • The Master suggests "we reconfigure our two TARDISes into time cone inverters... We create a stable safe zone by applying temporal inversion isometry to as much of space/time as we can isolate.".

Story Notes

  • This story was the last to feature Tom Baker as "the current" Doctor. He would reprise his role on screen only in recorded links for the video release of the incomplete Shada in 1992 and then on the Children in Need special Dimensions in Time (1993), and for the BBC Audio story arc Hornets' Nest in 2009. As of 2009, Tom Baker holds the record for having the longest tenure (seven years) as the Doctor on-screen, although both Sylvester McCoy and Paul McGann would later be considered the "current Doctor" for about nine years each.
  • The key plot point of shunting excess entropy into another universe was previously used in Isaac Asimov's novel The Gods Themselves.
  • This serial arguably — as pointed out in About Time 5 by Lawrence Miles and Tat Wood — has the largest body count of any Doctor Who story, albeit not graphically shown, as the destruction of Logopolis apparently causes a significant portion of the entire universe to be swallowed by a wave of entropy. At the very least, the Traken Union is destroyed, which would put the death toll in the billions and making the Master a mass killer on an unprecedented scale, albeit not by intent. The Last Great Time War potentially had a higher body count, however even were a death toll to be given, it occurred off-screen.

Closing Credits

At the end of Episode 4:

  • Tom Baker's face was electronically removed and the titles were re-shot with Peter Davison's face for the following story, Castrovalva.
  • The lead character was listed as "Doctor Who" for the last time for the next 24 years. Beginning with Castrovalva, until the series' cancellation in 1989, the character was credited simply as "The Doctor". The 1996 television film did not have an on-screen character name credit for either the Eighth Doctor or Seventh Doctor; however, the press kit for the film credits them as "The Doctor" and "The Old Doctor" respectively. The 2005 relaunch reverted to using "Doctor Who" until switching again to "The Doctor" starting with The Christmas Invasion.
  • This is the first episode to credit an actor after a regeneration. Two actors were credited as either "Doctor Who" or "The Doctor" for the first time when a regeneration scene was involved. This also happened at the ends of The Caves of Androzani, The Parting of the Ways and The End of Time. In both of the first two instances Peter Davison recieved second billing.
  • Peter Davison was credited as "Doctor Who" for the only time, hereafter credited as "The Doctor".

Discontinuity, Plot Holes, Errors

  • This story features the Doctor's TARDIS materialising around the Master's TARDIS and creating a gravity bubble and the recursive phenomena of infinite TARDIS'es nesting within each other. Two TARDIS's materialised "inside" each other in DW: The Time Monster, but did not happen when the TARDIS materialised inside Professor Chronotis's rooms (actually his TARDIS in disguise) in the untelevised DW: Shada. Chronotis's room was not a complete TARDIS; it was not dimensionally transcendant.
  • Why does the policeman take the doll-like corpses so seriously? Because he recognizes one of them as being the first constable seen in the story.
  • At the beginning of part 2, when the Doctor and Adric are going back to the TARDIS to escape the policemen, the Doctor opens the door to the right, however Adric goes through a door that is open to the left.
  • Surely the Doctor's plan of flooding the TARDIS to flush-out the Master is absurd nonsense. The Doctor was feeling very fatalistic at this point. It is doubtful there is a normal procedure of what to do when your arch-nemesis creates a gravity bubble within your TARDIS.
  • When the Master puts the bracelet onto Nyssa's wrist, part of it falls off.
  • In part four, when the Master enters his TARDIS, his shadow stays after it dematerialises.
  • Tegan appears amazingly reconciled to the extraordinary events happening around her. In particular she does not appear to comment on the size of the TARDIS. She witnesses the regeneration of the Doctor without any evident wonderment and without questioning what is happening. (Different people react to extraordinary events in different ways.)
  • The only indication that the Watcher is the Doctor's future self is Nyssa saying, 'so it was the Doctor all along'. But how does she know? (As he is merging with the Doctor laying on the ground, she works out that it must be the Doctor.)
  • It is never really explained how/why the Watcher has come into existence for this regeneration and not previous or future ones. It's a process that is not always necessary. It's been rather clearly shown that the Doctor does not have the smoothest time with regeneration. Sometimes he needs a little help, even if from a future part of himself.
  • The lock on the Master's TARDIS changes place in part 1. (A functioning chameleon circuit is more than capable of changing the location of the lock.)
  • In Part 4, the Master's TARDIS materialises just before the worker leaves the room, Surely the worker would have heard it?.
  • When Adric and Nyssa are "outside time and space", how can they possibly see things that change with the passing of time - i.e. the growing entropy field? (The TARDIS scanner could show them the areas of Space-Time in which they were interested, much as the Time-Space Visualiser could in DW: The Space Museum and The Chase.)
  • In the Tenth Doctor's final story, The Tenth Doctor falls from a tall height, but doesnt regenerate, but in this story The Doctor does. This is presumably different as the Fourth Doctor falls to his death, something which he had not planned. The Tenth Doctor was prolonging his regeneration as he did not want to die, thus potentially counteracting this story, showing that perhaps Timelords, or specifically, The Doctor, are able to hold off regenerating for a while. This may also explain Romana's regeneration in Destiny of The Daleks. She may have already beeen regenerating and merely held it off until she saw a body which she liked, in this case, Astra's. Another possibility is that he landed near the Immortality Gate, which could have been giving off excess energy that healed him. Also, in Paradise of Death, The Doctor survives a fall from a similar height by using what he calls "bone compression", at the cost of being knocked unconscious (and believed dead) for a brief period.
  • The Doctor's flashback of the Master is of him saying "Predictable as ever, Doctor.", from episode one of DW: The Deadly Assassin, but the Doctor was not actually present when the Master said that. He may have said the same thing to the Doctor's face at another meeting during that incarnation. He has made similar remarks to the Doctor on other occasions.
