Arc of Infinity (TV story)


 * For the Arc of Infinity itself, see separate entry.

Arc of Infinity was the first story of the anniversary Season 20. Janet Fielding returned as Tegan Jovanka in this serial, rejoining the Fifth Doctor and Nyssa on their travels. Future Doctor Colin Baker made his Who debut in this story, playing Commander Maxil. Of the several Doctor Who stories filmed outside the UK in the late 1970s-early 1980s, this was the only one to open a season.

Synopsis
Omega, an ancient Time Lord made of pure anti-matter, once defeated by the Doctor, is plotting to cross over into this dimension by bonding with the Doctor. Fearing total destruction from collision of matter and anti-matter, the Time Lords recall the Doctor to Gallifrey - to execute him!

Part one
On Gallifrey, a Time Lord is at work stealing the bio-data extract of another Time Lord and killing a technician who stumbles across the crime. The traitor provides the bio-data to a creature composed of anti-matter and uses the bio-data to invade the TARDIS and then the Doctor's metabolism. The Doctor's companion, Nyssa, helps him recover. The creature is shielded in this attempt by the Arc of Infinity, a curious curve between the dimensions containing quad radiation which can shield anti-matter. The Doctor decides to head to Gallifrey to track down the supplier of his bio-data, conscious that unless the creature trying to cross universes is stopped that its incursion could cause a fatal chain reaction to our universe.

Meanwhile, in Amsterdam, Netherlands, backpackers Robin Stuart and Colin Frazer decide to crash at the crypt of the Frankendael mansion. During the night, Colin hears something and investigates; he finds a curious birdlike creature, the Ergon, which hypnotises him. A terrified Robin runs away.

The High Council of the Time Lords is also taking the matter seriously and has decreed that the Doctor’s TARDIS should be recalled. The Chancellery Guard under the over-zealous Commander Maxil seizes the Doctor and Nyssa. When the Doctor resists arrest, Maxil shoots him...

Part two
The Doctor has been stunned to ensure his delivery to the High Council. When he is brought before the High Council the new Lord President, Borusa, is inscrutable while Chancellor Thalia and Cardinal Zorac are openly hostile; only his old friend Councillor Hedin seems pleased to see him.

The President stresses the gravity of the situation since the creature poses such a threat to the Universe, and the High Council has had no alternative but to issue a Warrant of Termination on the Doctor to ensure the creature can no longer bond with him. Fortunately an old friend, Damon, who is another technician in the records section, provides him with the proof he needs that a member of the High Council stole his bio-data extract.

Meanwhile, the Doctor's former companion, Tegan Jovanka, arrives in Amsterdam looking for her cousin Colin. Instead, she is greeted by Robin, who tells her that Colin has disappeared. When neither of them can persuade the police to take an interest they decide to investigate the crypt themselves.

The Doctor is soon taken for execution, despite Nyssa’s attempts to save him, and placed in a dispersal chamber. Sentence is carried out...

Part three
The supposed death of the Doctor, however, has not solved the situation. Unbeknownst to the High Council, his mind has been taken into the Time Lord living repository of knowledge, the Matrix, while his body is hidden behind a force shield in the termination cubicle. The creature is a renegade Time Lord, who demands an opportunity to return to the Universe it once inhabited. The truth of the aborted execution is discovered by the wily Castellan, who tells first Nyssa and Damon that the Doctor is alive; and then the High Council.

Tegan and Robin are attacked by the Ergon's weapon, a Matter conversion gun, and transported into a TARDIS hidden at the Frankendael and belonging to the renegade. Their minds are scanned, revealing to the creature that Tegan knows the Doctor. The Renegade uses Tegan as bait to force the Doctor to obey him, also releasing Colin from his slavery as a reward. The Doctor is returned to normal space on Gallifrey where he makes for the High Council Chamber. Lord President Borusa has fallen under suspicion of being a traitor because the Castellan reveals it was his codes that were used to transmit the bio-data. The truth, however, is that Councillor Hedin is the traitor. He is in awe of his master - the mighty Omega, first of the Time Lords and pioneer of time travel (see The Three Doctors).

Hedin wishes to release Omega from his exile in a universe of anti-matter, not realising the great Time Lord has been driven mad by his years of solitary confinement. The Castellan kills Hedin, but this does not prevent Omega using the Arc of Infinity to seize total control of the Matrix and, therefore, the organisation of Gallifrey...

Part four
Fortunately the Doctor and Nyssa manage to slip away and return to the TARDIS. They use scant knowledge provided by Tegan to determine that Omega has established its base in Amsterdam on Earth, and head there immediately, desperately trying to find the Frankendael crypt she described. After a lengthy hunt they find the lair defended by the Ergon, and Nyssa disposes of it with its own matter-converter gun. They reach Omega’s TARDIS at the point at which both the ship is destroyed and Omega makes full transference to Earth using the Arc of Infinity. When he peels his decayed mask away he reveals the features of the Doctor.

Omega heads off into Amsterdam with the Doctor and Nyssa in hot pursuit. Within a short time the Doctor’s prediction of an unstable transfer begins to come true: Omega’s flesh decays and it is clear his new body is not permanent. When the Doctor and Nyssa catch up with him it is a painful task for the Doctor to use the Ergon’s anti-matter converter on Omega, expelling him back to his own universe of anti-matter. The Time Lord High Council on Gallifrey detects the end of the threat.

Once Tegan has checked on her cousin’s progress in hospital, she decides to rejoin the TARDIS crew. This time it is as a willing traveller. The Doctor, Tegan and Nyssa depart Amsterdam.

Biology

 * In order to remain in our Universe Omega needs to bond with a Time Lord, thus reversing his polarity, and to that end Hedin steals and transmits the Doctor's bio-data extract.

The Doctor

 * The Doctor asks Damon about Leela.
 * Reference is made to the Doctor's failure to return Romana.
 * Hedin is also an old friend of the Doctor's.
 * After finding himself "vaporised" the Doctor appears in The Matrix.
 * The Doctor's palm print has been cancelled so that he cannot open doors on Gallifrey, but he can still remember the President's code: 4553916592.

Individuals

 * Tegan has lost her job as an air stewardess and was hoping that meeting Colin Frazer; her favourite cousin, would cheer her up.
 * Damon tells the doctor that Leela is well when they are going to Nyssa's room

Races and species

 * The Doctor dismisses the Ergon as one of Omega's less successful attempts at psycho-synthesis.

TARDIS

 * Omega has acquired a TARDIS.
 * Maxil removes the heart of the TARDIS (or part of it).
 * Nyssa says the Doctor's TARDIS' navigation system needs some repair work after it was damaged by the Cybermen.
 * The Doctor is recalled to Gallifrey, once on Gallifrey the Doctor's TARDIS is incapacitated by the removal of the main space-time element from under the console, although Damon later replaces it with one without a recall unit.

Time Lords

 * Borusa has regenerated again and is now Lord President.
 * The Castellan mentions that the destruction of a Time Lord has only been ordered once before. This is a reference to the renegade Time Lord Morbius.
 * The Time Lords use Impulse Lasers.

Story notes

 * The working titles for this story were The Time Of Neman and The Time Of Omega.
 * For Parts One and Two, the character of Omega was credited as "The Renegade" on the end credits.
 * John Horsley was a contender for the role of President Borusa.
 * John Nathan Turner appears on screen in part four trying to persuade a passer by not to get into shot.
 * Distinguished actor Michael Gough, who had previously played the Celestial Toymaker in the story of the same name (The Celestial Toymaker) and been married to Anneke Wills, appears here as the misguided traitor, Hedin.
 * Colin Baker (who would later succeed Peter Davison as the Sixth Doctor) appeared in the serial as Commander Maxil. It was his performance in this role (which, according to Baker, producer John Nathan-Turner repeatedly told him to "tone down") that first brought him to the attention of the production office. Baker reprised the role of Maxil as an uncredited cameo in the 2006 Big Finish Productions audio play Appropriation.
 * Ian Collier takes on the role of Omega, originally played by Stephen Thorne in The Three Doctors. Collier had appeared once before in the series, as Stuart Hyde in The Time Monster.
 * Leonard Sachs, previously seen as Admiral de Coligny in The Massacre of St Bartholomew's Eve, plays the latest incarnation of Borusa, now elevated to the position of Lord President.

Myths

 * New regular costumes for Nyssa and Tegan are seen for the first time in this story. (Although Tegan's new costume makes its debut here, Nyssa's is not seen until the following story, Snakedance. This myth derives from the fact that numerous publicity photographs of the two actresses wearing their new costumes were taken during Arc of Infinity's location shoot in Amsterdam. These photo shoots were made possible by the fact that Snakedance was completed before Arc.)

Continuity

 * Every story during Season 20 featured a component of the story from the show's past. For this serial, it was Omega, who last faced the first three incarnations of the Doctor in the 10th anniversary story DW: The Three Doctors.
 * Tegan is the first companion to have rejoined the Doctor on his travels, after having departed (although other companions/recurring characters had previously left the Doctor's company then reappeared). Though she only departed in DW: Time-Flight, the previous story, the Doctor and Nyssa travelled without her in stories in other media.
 * This Castellan, played by Paul Jerrico, would return in DW: The Five Doctors.
 * The Matrix was first introduced in DW: The Deadly Assassin.
 * In DW: Time Crash, when the Tenth Doctor commented on the era of the Fifth Doctor, he mentioned "Time Lords in silly hats", a reference to Time Lord apparel such as was seen in this story.
 * Hedin and Omega appear in PDA: The Infinity Doctors
 * Omega also appears in BFA: Omega.
 * A traitor at work on Gallifrey was also used as a plot device in both DW:The Deadly Assassin and The Five Doctors.
 * Thalia comments on the Doctor's inability to return Romana to Gallifrey. The Doctor tells her that she chose to stay in E-Space. These events occurred in DW: Warriors' Gate.
 * The dress worn by Nyssa at Cranleigh Hall is in her room. It appeared in DW: Black Orchid.

Timeline

 * This story occurs after ST: The Juror's Story
 * This story occurs before BFA: Omega

DVD releases
This story was originally released in a double-pack with Time-Flight in Region 2 and 4, but released singly in Region 1.

The R2 cover art of this story and Time-Flight shows the "Peter Davison Years" as 1981-1984. All other Davison-era releases have claimed the years as 1982-1984, in deference to the January, 1982 broadcast of Castrovalva. However, there is justification for calling the era 1981-1984, as that's the period of time Davison actually worked on the programme. Like Jon Pertwee, Davison fell victim to the BBC's decision to push back the premiere of his first series to the start of the new calendar year. Neither actor is generally credited for their first year on the job, making their eras appear a little shorter than they actually were. While Pertwee only filmed about half of Season 7 in 1969, almost everything of Season 19 was filmed in 1981. Indeed, Davison's first work on the series — his regeneration scene — had been filmed on 9th January 1981, almost a full year prior to the release of Castrovalva. Ironically, the only part of Davison's initial year not filmed in 1981 was Time-Flight, the only other DVD release to bear the claim of an era lasting from 1981-1984. All told, Davison's time in front of the cameras as the Doctor lasted from 9th January 1981 to 12th January 1984 — almost precisely the three-year tenure he had been advised by Patrick Troughton to undertake.
