Full Circle was the third serial of season 18 of Doctor Who. It was the first story of the E-Space trilogy.

Synopsis Edit

The TARDIS falls through a CVE into E-Space and arrives on the planet Alzarius. There the inhabitants of a crashed starliner and a group of young rebels called the Outlers, led by a boy named Varsh and including his brother Adric, are terrorised by a race of Marshmen who emerge from the marshes at a time known as Mistfall.

The Doctor discovers that the starliner's inhabitants are not the descendants of its original crew, as claimed by their leaders, the Deciders, but evolved Marshmen. With the Time Lord's help and encouragement, the starliner is repaired and able to leave the planet.

Plot Edit

Part 1 Edit

The Fourth Doctor has K9 implement the coordinates for Gallifrey into the TARDIS console, having been summoned there at the behest of the Time Lord High Council. Romana disappears back to her room and confesses to the Doctor that she doesn't want to be returned to the Time Lords to live out her life on Gallifrey. While the TARDIS is in flight, it passes through a bizarre space/time event and into a green void. While the Doctor attempts to figure out what happened, the TARDIS lands and the scanner shows an image of Gallifrey, but they step outside to find themselves somewhere completely different.

Cells

The cells of an Alzarian, exactly the same as that of the Marshmen and Alzarian spider.

Nearby is a small but sustainable civilisation of humanoids who live between a river and a grounded but not irreparable spaceship called the Starliner. They came to the planet Alzarius from Terradon. Much of the focus of society is on repairing their craft. It is an oligarchy ruled by three self-selecting senior colonists knows as Deciders. They ensure the smooth running and order of their adopted world and lay particular store on technical ability. One of the brightest of the younger generation of colonists is Adric, who bears a Badge of Mathematical Excellence in recognition of his computational skills. Adric's brother, Varsh, has rejected the regimented society of the Starliner. He leads a band of rebels called Outlers, who steal harvested riverfruit and other foods to survive. The Outlers attempt to steal some of these riverfruits, but fail and retreat to their cave.

Not all is well in the colony. Strange eggs have started to appear in the riverfruit. This is interpreted by First Decider Draith and scientists Dexeter arrive to examine the inside of riverfruits. In the TARDIS, the Doctor tries to determine their location, but the scanner and coordinates are both stating that the planet is Gallifrey. Back in to the village, Draith, using the precious System Files of the Starliner, views the appearance of these eggs as an omen of Mistfall, a strange periodic change to the planet during which the natural balance of society is threatened. In the Outlers cave, Adric makes a plea to Varsh to allow him to join the Outlers, but none of the members are convinced of his intentions or loyalty and come up with a means of him proving himself. Soon Mistfall begins, and the colonists move into the Starliner to protect themselves, apparently in a well prepared manner. Adric chooses the moment of confusion to try and steal some riverfruit to prove himself to his brother. Draith gives chase to his young protégé but falls in the river – only to be dragged beneath the waves by a strange force. His last words are aimed at the chief scientists of the colony: “Tell Dexeter we've come full circle!" Adric muses on this as he heads into the forest in panic, finding his way into the TARDIS. The Doctor and Romana take him in and tend to his leg wound, which recovers remarkably quickly. The Doctor and Romana conclude that the reason the scanner isn't working is down to the negative coordinates, something which their space doesn't have, meaning that they are no longer in their space. The Doctor heads off to investigate the marshes that Adric mentioned in his delirium, while Adric attracts Varsh and the other Outlers to the protection of the TARDIS.

The two other Deciders, Garif and Nefred, have meanwhile ordered the Starliner doors closed as per procedure, knowing that both Draith and Keara, an Outler and the daughter of a prominent citizen called Login, have not entered the ship safely. Despite his worries, Login soon accepts a position as Third Decider when it is determined that Draith has died. It is as well the doors have been closed. At the swamp, the Doctor and K9 are still examining the mist, when humanoid, aggressive Marshmen begin to appear from underwater, looking threatening.

Part 2 Edit

The Marshmen continue to rise from the water as the Doctor observes. In the Outlers cave, Adric is telling the others about the TARDIS and Varsh, now convinced of the danger of Mistfall, decides to relocate there and take control, against Adric's wishes. The Doctor and K9 move out of sight as the Marshmen move away and the Doctor has K9 follow them while he returns to the TARDIS. While Romana works, the Outlers, followed by Adric, arrive at the TARDIS and declare their intention to seize it. On the Starliner, Nefred and Gariff summon Login and offer him the position of third decider, which he accepts. K9 continues to follow the Marshmen, until they cross a small river bed he is unable to cross. Romana is still at the mercy of the Outlers before Adric intervenes and Romana regains control. Suddenly, the TARDIS rocks violently, as if it were being carried.

The Doctor returns to where the TARDIS was to find it gone without trace. He proceeds further down to hill and stumbles across the Starliner in the distance; he heads over to it. While the Marshmen beat on the walls of the Starliner to gain entry but the fearsome primitive creatures are not admitted, the Doctor gains entry to the Starliner using his sonic screwdriver, followed by a young and inquisitive Marshchild. Nefred addresses the colony of the Starliner as the Doctor and the Marshchild roam free. The TARDIS stops rocking, but Romana can't establish what's outside as the scanner still shows pictures of Gallifrey. Romana looks out of the doors to find the TARDIS in the Outler's cave, surrounded by Marshmen. The Marshchild, lost and afraid, roams through the Starliner, stumbling across some of the citizens. The Doctor tries to reach out to the Marshchild, but a citzen knocks him unconscious and capture the Marshchild. Both are taken and brought before the Deciders. Gariff orders the Marshchild taken to Dexeter for examination.

In the Outlers' cave, the Marshmen beat on the TARDIS trying to gain entry. Romana decides to venture outside. K9 comes to rescue her and the others from the Marshmen, but he had his head knocked off. Romana and Adric deduce that the Marshmen are intending to use the TARDIS as a battering ram to force their way into the Starliner by throwing it down the mountain. The Deciders continue to question the Doctor, who tells them about Decider Draith and the truth about the mists, making Login hopeful that Keara, his daughter, is still alive. Dexeter then arrives and the Doctor goes with him to examine the Marshchild. Back in the cave, the Marshmen suddenly retreat, and when the group step outside to investigate, Marshspiders start emerging from the riverfruits in the cave. Varsh, Tylos, Keara and Adric retreat into the TARDIS. In a panic, Tylos shuts Romana out; when Adric tries to open the doors, he accidentally dematerialises the TARDIS without her. Romana is ambushed by the spiders, picking up a riverfruit to fight them off, but a spider bursts out of it. She is bitten by one of the Marshspiders and falls unconscious.

Part 3 Edit

The Doctor and Dexeter examine the Marshchild and the Doctor is angered to discover Dexeter has been conducting more experiments on it. Login arrives and arranges a deal with the Doctor that if he helps him find his daughter, he will help locate the TARDIS. Suddenly, the TARDIS arrives. When the Outlers emerge Login is reunited with his daughter, but the Doctor is not impressed not to be reunited with Romana. Thus he pilots the TARDIS back to the cave, and finds an alert but amnesiac Romana. On the Starliner, Varsh, Keara and Tylos are put in front on an enquiry, while Dexeter convinces the Deciders to allow him to experiment on the Marshchild. The Doctor scoops up the remains of a Marshspider and K9 and then reverses his journey once more with Adric and an unconscious Romana in tow. By the time he is back in the Starliner, however, Dexeter has tried to examine the brain of the Marshchild, provoking it to attack, killing both Dexeter and itself in a state of panic. The Doctor sends Adric back to the TARDIS and is so incensed that he turns on the Deciders and denounces their society – revealing secret ship controls that show the Starliner has been ready to pilot from Alzarius for centuries but, for some reason, the farce of constant repair has been continued. The problem it seems is that though the Deciders understand the technical construction of the ship, no one knows how to pilot it.

Varsh, Keara and Tylos are put to work doing maintenance on the Starliner systems. The Doctor persuades the Deciders to give him equipment to examine the cells of the Marshspider, Marshchild and Dexeter and also deduces that they are from identical DNA sources. Adric arrives and informs the Doctor that Romana has vanished. When they go back to the TARDIS, they find her room ransacked and go in search of her. At the lower section of the Starliner, Romana, now completely under the influence of the Marshspider's venom, releases the emergency exits and allows the Marshmen to invade the Starliner.

Part 4 Edit

The Marshmen storm the Starliner in droves and Romana opens another exit allowing more and more of them in. While Varsh, Keara and Tylos are working on the ship, they encounter the invading Marshmen, but Varsh distracts them with the contents of his bag and they flee, but Tylos is killed trying to help someone escape. Varsh and Keara meet up with the Doctor and Adric and the Doctor hustles them into the science unit. The colonists retreat before the creatures, many of whom are more inquisitive than dangerous, but anarchy reigns. The Doctor returns to the TARDIS but is cornered by Romana and the Marshmen. In the science unit, Varsh grows impatient and Adric swaps a microscopes functioning image translator with a broken one. The Doctor tries to break Romana's conditioning to no avail, but manages to keep subliminally chained to the TARDIS. In the main book room, the Deciders come up with a plan when the Marshmen begin to invade and the inhabitants evacuate. Nefred is mortally wounded while fleeing, along with many others.

In the science unit, the Doctor barricades the door and uses the microscope (which Adric returns the image translator for) to examine Dexeter's DNA samples. He and the Outlers concoct a serum which should break Romana's influence when the Marshmen attack the door and begin breaking in. Login orders the citizens to seal the emergency exits, and then he and Gariff plea with Nefred for guidance, of which he has none other than to ask the Doctor's help in piloting the Starliner. His last admission is that the colonists cannot return to Terradon, because they've never been there. Gariff and Login go and search for the Doctor.

The Marshmen invade the science unit, but the Doctor manages to keep them at bay using oxygen canisters, as the oxygen contained is too high concentration for them to adapt quickly enough. The possessed Romana enters the unit and attacks the Doctor, before Adric knocks her unconscious with the oxygen in the canister. The Deciders discover the Outlers forcing the Marshmen out. The Doctor uses the protein serum to cure Romana. The Doctor and Romana determine from research that the ship has been maintained for 40,000 generations by a species that has three aspects; spiders, Marshmen, and the current humanoids. The Marshmen continue to attack, and Adric's cylinder runs out of oxygen. Varsh remains to fend them off, but as he's escaping, he's pulled through the closing door and killed, despite Adric's attempts to save him. The Doctor has Login flood the Starliner with the oxygen to force the Marshmen's retreat, while Adric and Keara mourn Varsh.
Romana Awakes

Romana awakes from the hypnosis of the spider.

The Starliner is filled with concentrated oxygen and the Marshmen leave through the emergency exits. The Doctor explains to Gariff and Login that the present-day Alzarians are actually a subspecies of the Marshmen, who wiped out the Starliner's original Terradonian crew and then gradually evolved into human form to take their place. They are all from the same DNA and thus have come "full circle". This is the real secret of the System Files. As the Doctor and the Deciders head to the TARDIS, Adric runs inside and puts the functioning image translator on the console for the Doctor to find. The Doctor shows the Deciders how to operate the ship's flight so they can manage on their own, before returning to the TARDIS. In the control room, the Doctor finds an image translator left by Adric, which he uses to ensure where they were. It emerges they have journeyed to this pocket universe through a rare space/time phenomenon known as a Charged Vacuum Emboitment. They then watch the Starliner take off and leave Alzarius. Both the Doctor and Romana forlornly concede that until they find another CVE to escape through, they're trapped in E-Space...

  • Adric bears a star badge for his mathematical excellence and as a member of the Elite.
  • Romana has a chess set in her room.

Medicine Edit

  • Anaesthetic is used to sedate the Marshman once known as Draith.
  • The Doctor uses an Alzarian microscope able to see chromosomical details (such as karyotypes) to analise the tissues of the Marshmen and the spider.
  • An excess of oxygen is able to affect the Marshmen.
  • Romana suggests using gel electrophoresis to analyse the specimen from the Marshmen.

Spacecraft Edit

Space-time anomalies Edit

Species Edit

  • Alzarians were divided in three ranks: Deciders (leaders, in number of three), Citizens (common people) and Outlers (rebels). Elite was a cross rank for intellectual excellence. Romana classifies this society as a "a type D oligarchy".
  • Humanoid Alzarians share the same genetic pattern of the Alzarian spiders and the Marshmen, because they represent a different evolutionary strata, thanks to a rapid cellular adaptation.

TARDIS Edit

  • Adric is given a spherical homing device to let him track down the TARDIS.
  • Romana estimates that the TARDIS weighs "5 times 10 to the 6 kilos" in the gravity of the planet.

Technology Edit

  • The technology of Gallifrey and Alzarius/Terradon is interchangeable. The Doctor uses the image translator from the starliner in the TARDIS.
  • The Starliner is provided with an electrolythic power system able to produce oxygen.
  • The Doctor wonders why, among their tasks, the crew of the Starliner removes optrionics circuits.

Story notes Edit

  • This is the first story in the "E-Space Trilogy".
  • The story has a working title of The Planet that Slept.
  • Adric's name was suggested by script editor Christopher H. Bidmead as an anagram of the last name of eminent physicist P A M Dirac (who in 1930 was the first to predict the existence of antimatter).
  • Billy McColl was considered for the role of Tylos and John Franklyn-Robbins was considered for Garif. (TCH 32)

  • When the TARDIS is seen drifting through E-Space, the background stars appear in front of the TARDIS.
  • The Marshmen have cuffs.
  • As is often the case in the show, CSO backdrops are used to add depth to some of the corridors in the Starliner. Sometimes, however, the background is not superimposed, and only a blank screen is visible.
