Inferno (TV story)

Inferno was the fourth and final story of Season 7 of Doctor Who. It was the last story to feature Caroline John as Liz Shaw, although her departure is not depicted. It was also the first Doctor Who story to explore the concept of parallel universes.

You may wish to consult Inferno for other, similarly-named pages.

Inferno was the first story in which producer Barry Letts had any say on development and commissioning. Director Douglas Camfield fell ill after completing parts one and two. This left Letts to direct the other five parts.

Several possible stories were considered for the season finale. The Mists of Madness by Brian Wright and The Shadow People by Charlotte and Dennis Plimmer were two. However, Wright was unavailable and the Plimmers abandoned the project after a pay dispute. This left the way open for The Mo-Hole Project, as it was then titled, by Don Houghton. The serial went through several name changes before becoming Inferno.

Houghton had based the drilling part of the story on real events. He had contacted the American Embassy to enquire about Project Mohole, a real world attempt to drill through the Earth's crust. Information on the project and why it was abandoned was not disclosed as such information was top secret. It was this secrecy that Houghton developed upon for his story.

Letts was worried when the first script draft arrived as he did not think there was enough in it to fill a seven-parter. Additions such as the Primords and scenes featuring Venusian aikido were made to suitably lengthen the script.

Synopsis

UNIT is providing security cover at an experimental drilling project designed to penetrate the Earth's crust and release a previously untapped source of energy. Soon however the drill head starts to leak an oily green liquid that transforms those who touch it into vicious primeval creatures with a craving for heat.

The Doctor is accidentally transported by the partially repaired TARDIS control console into a parallel universe where the drilling project is at a more advanced stage. Thwarted by his friends' ruthless alter egos, he works to save both universes.

Plot

Episode 1

The Doctor drives Bessie into an area marked restricted.

 
The irrational Professor Stahlman dismisses the concerns of Sir Keith.

A maintenance worker by the name of Harry Slocum enters a drilling unit nicknamed Inferno. He introduces himself to Sir Keith and is told there is an issue with pipe number two. He is urged to fix it quickly as Professor Stahlman does not want any delays. The Professor is at loggerheads with Sir Keith and tells him he should never have stopped the pipe for maintenance. He tells Sir Keith never to make a decision with regards to the drilling again.

As Slocum is fixing the pipe he sees a green goo emanating from the base. He touches it and it burns. He is horrified to see his hand turn green.

Sir Keith discusses the Professor with his Personal Assistant Petra. He confides that he has sent for an expert in oil rig mining, Greg Sutton, as he is nervous that there is no one with real drilling expertise on the mission.

As Slocum leaves he seems entranced. He heads outside the complex and stumbles against a piece of scaffolding. A man rushes out to help him. With a growl Slocum turns on him and kills him with his wrench.

In a room inside the complex, Benton is hanging s picture in what is to be the UNIT HQ. The Brigadier enters and asks if there has been any sightings of Slocum. Benton says there hasn't been. The Doctor enters and the Brigadier tells him of the murder. He shows him the wrench. It is still warm and, when it was found, it was red hot. The Brigadier comments that trouble seems to follow the Doctor around and he questions why he asked to be on this mission. The Doctor says that an opportunity to be at the first penetration of the Earth's crust was not to be turned down. He heads off to do some experiments of his own.

Sutton has arrived and is bewildered at having been pulled over with such urgency. Sir Keith shows him around the complex. He says that the drill head is twenty miles deep. This has been achieved by having no pipes - the pipes visible containing coolant delivered to the drill bit. Instead there is a robot drill that is fed by a cable from a nuclear reactor. Sutton asks what this is hoping to achieve. The project is aiming to pipe Stahlman's Gas - named after the Professor - a powerful energy source trapped inside the Earth's crust since the dawn of time. Sir Keith begins to introduce Sutton to the staff. He tries to flirt with Petra and is snubbed. On introduction to the Professor he is cold. The Professor thinks that Sir Keith is trying to introduce as many experts into the project as he can to try and close it down. He counts the Doctor as one of these. Sir Keith introduces Sutton to the Doctor and asks his opinion on the project. He says that they should be heeding the warnings of the computers. As he leaves he overhears the Professor complaining about the experts to Petra. He causally, but loudly, points out a flaw in the mechanics to a near by scientist - causing the Professor's blood to boil.

The Doctor pulls up to a small building being guarded by a UNIT soldier. He asks if there is any news about Slocum- he is told that there isn't. The Doctor uses a device to open the door to the building remotely and drives Bessie in. Liz is inside working on the TARDIS console. The Doctor hands over the figures from the computer and tells her of the murder. She already knows as the sentry told her. They discuss the real reason they are here. The Doctor wants to use the nuclear power to try and jump start his TARDIS console. He wants a test run straight away. Liz starts flicking switches and positions herself by the main switch.

Slocum is skulking around the complex. He is now covered in hair and has claws. He enters a building. A member of UNIT is in the phone. Slocum approaches him from behind.

The Doctor says he is ready. Liz pulls the lever down. The machine registers 7 mega volts.

Slocum has killed the UNIT soldier. He pulls a switch down to maximum.

"Too much power, Liz!"

The console begins to shake. The Doctor says that there is too much power. Liz cannot do anything as the circuits are locked. The console and the Doctor dematerialise.

The Doctor is in some kind of limbo and is in some pain as he and the console fly through the darkness. He flies off into the black.

Liz uses a plank of wood to force the levers down.

The Doctor and the console reappear. The Doctor is groggy but fine. He is keen for another trial run. Liz tries to dissuade him but he says he needs to know where he was. An alarm goes off. It is the drill head. The Doctor and Liz hurry off to Bessie.

The complex is in lock down as the drilling room fills with smoke. The Professor argues with Sir Keith as to why he ordered the lockdown. Sir Keith implores him to shut off the power but he refuses. Sutton says that if the power is stopped now it will never be able to be restarted again. Petra is ordered to go and check the coolant. Sutton tries to stop her saying that the pressure is too dangerous but she doesn't care. The Doctor and Liz enter. The Doctor says that there has been a nuclear power surge. The Brigadier enters and says that there has been another murder. The Doctor goes to the Professor to give him his advice but he tells him to stop wasting his time. The Doctor heads off with the Brigadier. Petra returns saying that the controls are jammed with the heat. Suffolk tries to stop her from heading off but instead goes with her to help. They find the Professor trying to stop it manually. Sutton helps.

The Doctor and the Brigadier go to examine the body. As they do Slocum jumps up, growling.

Episode 2

The Doctor tries to calm Slocum down while he screeches horribly but a UNIT soldier, Wyatt, tries to shoot Slocum and is attacked. Slocum eventually collapses, as does Wyatt, and the former's body is so hot that it scorches the wall where he falls.

 
The Doctor and Liz examine a vial of mysterious green liquid.

The Doctor voices his concern that Slocum's mutated form seems to be filled with some strange power. He has also heard the screeching before — during the 1883 explosion of Krakatoa. Benton informs the Brigadier that Bromley and Wyatt have gone missing, before their medical checkups. The Doctor encounters Wyatt, who is in the process of mutating, on the cooling towers. Wyatt falls to his death, but the Doctor fails to notice the mutated Bromley on the tower as well.

The drill has been bringing up more quantities of the green slime, but Stahlman dismisses any connection between that and the incidents at the project. When a jar of the slime starts to bubble over, he quickly grips it, superficially burning his hand. Stahlman places the jar in a box which he orders frozen, and secretly sabotages the project computer, which was predicting disaster, by stamping on the computer's micro-circuit. He also orders that the power be cut off to the Doctor's hut, so that the drilling can be accelerated, with penetration occurring in 49 hours. The Doctor, in the meantime, sends Liz away on a wild goose chase while he hooks up the console again. Noticing the power drain, Stahlman cuts the power to the console just as Liz and the Brigadier rush back to the hut. As they look on, the Doctor, his console, and his car Bessie vanish into thin air...

Episode 3

Liz tells Stahlman he must restore power to the Doctor's hut, but the Professor is indifferent.

The Doctor wakes up apparently still in the hut, but when he drives away in Bessie he is shot at by soldiers, including Benton. Benton and his men follow and kill a Primord. Just as he believes he has shaken off pursuit, he encounters Liz dressed as a soldier. She captures him and takes him for questioning to Brigade Leader Lethbridge-Stewart, a sinister version of the Brigadier with an eye-patch.

None of the people encountered are the people he knows, as the Doctor quickly deduces that he has travelled to a parallel universe. The Inferno project is also ongoing in this universe and is slightly more advanced. The Doctor is presumed to be a spy because of his knowledge on the project.

On this world, a Republic of Great Britain exists, and is run by a fascist regime after the execution of the Royal Family, possibly in 1943. The security is provided by the Brigade Leader, Section Leader Elizabeth Shaw, and Platoon Under Leader Benton - all part of the Republican Security Forces, that world's counterpart to UNIT.

When an emergency with the pipes develops he tries to lend a hand, but he is caught by Benton, who threatens him at gunpoint with the words, "Are you coming with me, or do I shoot you here and now?"

Episode 4

The Section Leader enters and stops Benton from killing the Doctor. It is only with the Doctor's help that the crisis is averted, but he is interrogated and thrown into a cell regardless.

He tries to convince the parallel versions of his friends that he is from another universe, but they believe he is trying to feign insanity. Here, Stahlman has also been infected with the green slime, and is mutating. The Doctor is interrogated by the Section Leader and Brigade Leader, and he is taken away after he asks Stahlman to take off his glove. It does no good, since he has his hand bandaged. The Doctor is placed in a cell with a sedated Bromley, but the alarm is raised when Bromley awakens fully mutated. Meanwhile, in the Doctor's universe, Sir Keith has decided to go to the minister to try and slow the project down.

Escaping, the Doctor makes his way to the main control room to stop the drilling but is discovered. The Doctor pleads for them to stop, telling them that the screeching is the sound of the planet "screaming out its rage." Stahlman holds him at gunpoint, with the countdown at 1 second before penetration...

Episode 5

As Stahlman holds a gun on the Doctor, penetration is achieved, an explosion is heard, and an earth tremor rocks the installation. The temperature rises rapidly as more green slime oozes out of the cracked pipes. As the Doctor and the parallel Sutton try to contain the explosion, Stahlman attacks them. They manage to escape, leaving Stahlman behind a heat shield with the bodies of the unconscious workers. Stahlman rubs the slime on their faces, mutating them as well. There are seismic disturbances all over the country, and the Doctor explains that now that the crust has been penetrated, the planet will soon revert back to the gases it sprung from, saying they have "reached the point of no return", and that they will never be able to plug the hole, as nothing can withstand the immense pressures of the mantle.

When one of the Primords attack, the surviving people at the base find that they can be killed by cold from fire extinguishers. The government abandons them to their fate. The Doctor tries to convince the others that he can stop this from happening in his own universe if they will help him to return, and shows them the TARDIS console. He drains all energy from the TARDIS storage unit, and the Brigade Leader asks him to bring them back if they give him the necessary power. Meanwhile, Stahlman has fully converted into a Primord, and, in the original universe, Sir Keith's car has crashed.

The Brigade Leader demands that the Doctor save them, too, but the Doctor says that they do not belong in the other universe. Refusing to accept this, the Brigade Leader orders everyone back to the control room, where Stahlman and his fellow mutants attack, infecting Benton as well. In the office, the Doctor starts to explain his plan, but a Primoid's arm breaks through the glass...

Episode 6

Finally agreeing to help the Doctor, the group fights their way out using fire extinguishers to paralyse the mutants. By this time, the sky has turned red and the heat is overwhelming. The parallel Petra Williams, with Greg Sutton's help, manages to feed power to the TARDIS console. At the last moment, the Brigade Leader snaps and threatens to shoot the Doctor if he doesn't save them, but is gunned down by Section Leader Shaw. A wall of lava sweeps towards the hut and the others watch the end coming towards them.

Episode 7

The Doctor is back but unconscious in a healing coma, and there are only three hours left before penetration zero. When he awakes, the Doctor goes to the main control room and tries to smash the controls. He is unsuccessful and has to be restrained, but manages to tell Liz to put a new circuit into the computer that Stahlman had sabotaged. Liz does so, and the computer advises drilling be stopped at once. In the meantime, Stahlman orders everyone out of the drill head area, then when they are gone he picks up a handful of slime and rubs it into his face, causing himself to completely mutate. The Doctor escapes from the sickbay and returns to the control room, dealing with the Bromley mutant on the way. The Stahlman mutant emerges and has to be subdued with fire extinguishers. With seconds to go, the drill is shut down. The Doctor recommends to Sir Keith that arrangements be made for the shaft filled in.

Later, Sir Keith, who suffered only minor injuries in the crash, informs the Doctor that the project is being abandoned and everyone is leaving. The Doctor announces that he, too, is leaving. The Brigadier and Liz protest, and the Doctor sharply tells the Brigadier that he reminds him of his fascist counterpart. The Doctor activates the console and vanishes; on this occasion, Bessie is left behind. A few minutes later, the Doctor appears at the door of the hut, with mud on his clothes – having only made it as far as a nearby garbage dump. Suitably chastened, he asks the Brigadier to help him retrieve the console: it has landed in a somewhat inaccessible position, much to Liz's amusement.

Theories and concepts

  • The Doctor claims a dimensional paradox would result from bringing anyone from the parallel Earth back to Earth's universe.
  • The Doctor refers to this travel to an alternate universe as travelling "sideways" in time.
  • Events in the other world are running ahead of the "regular" Earth (Sir Keith's accident, Penetration Zero etc).
  • The Doctor sarcastically wonders whether Sutton was expecting his TARDIS console to be a space rocket with Batman at the controls.

Individuals

  • The Doctor met King Edward VII in Paris. He states he was at Krakatoa during the eruption of 1883, during which he heard the screeching sound the Primords made, implying that he had encountered (or at least heard) the creatures before.
  • The Doctor is the only individual in this story to not have a counterpart in the parallel universe. Although it was later confirmed that the Leader, an individual seen in a picture behind the Brigade Leader was the parallel Earth's version of the Doctor.

TARDIS

  • The TARDIS console is removable and can travel by itself, although it needs an external power source to do this.

Tools

  • Slocum murders a technician with a wrench.

Story notes

  • This story had the working titles of The Mo-Hole Project, Operation: Mole-Bore, The Mole-Bore and Project Inferno.
  • The primordial mutant creatures are named "Primords" in the closing credits of episodes five and six and publicity material, but are left unnamed in the story's dialogue.
  • The opening credits for this serial were unusual in that after the initial titles, the name and part number of the serial were superimposed on footage of a lava flow, with no music.
  • The Radio Times programme listing for episode one was accompanied by a black and white rehearsal shot of the Doctor standing at the TARDIS console, with the accompanying caption "Knock, knock. Who's there? 5.15", while that for episode seven was accompanied by a black and white photograph of the mutated Director Stahlman, with the accompanying caption "Meeting the Primord. Dr. Who: 5.25".
  • In spite of Douglas Camfield receiving sole credit as director, the second studio recording block and studio blocks 3 & 4 were directed by producer Barry Letts after Camfield had a minor heart attack on 27 April 1970. Letts later stated that Camfield's preparations for episode one's studio recording were so meticulous that he just followed Camfield's existing camera script. For the other episodes, Letts worked to his own plans, which he had to hurriedly construct. In the end, Camfield directed all the location filming and designed the direction executed by Letts on episode one's studio recording. Nevertheless, Camfield remained credited as director, as BBC regulations at the time forbade the same person being credited as producer and director.
  • Derek Ware did not perform the scene where the mutated RSF Private Wyatt is shot and falls to his death from the top of one of the cooling towers, in case he was injured, as he was also needed for studio recording. His place was taken by Roy Scammell who, curiously, also played the RSF sentry who fires the fatal shot. Ware stated in an interview that Scammell had already signed the contract to do the fall before Ware had been cast as Wyatt.
  • The role of Petra was given to Sheila Dunn (Douglas Camfield's wife) after Kate O'Mara was not available to play the part. O'Mara would, years later, be cast as the Rani, a renegade Time Lord.
  • Episode six has a small damaged section on the tape, which the Doctor Who Restoration Team replaced by painstakingly recolouring the appropriate section of the existing 16mm black & white film telerecordings.
  • Caroline John enjoyed her role as Section Leader Elizabeth Shaw and says that it was fun playing 'baddie' Liz. She also says she hated doing the scenes when she was playing the 'goodie' version because it was boring compared to being an evil character. She was particularly upset though about the scene in which Shaw shoots Brigade Leader Lethbridge-Stewart, as she was pregnant at the time. As a result, the scene was recorded with the weapon fired from out-of-shot, after which Shaw was shown returning the gun to her holster.
  • Nicholas Courtney has also said he enjoyed playing the parallel version of the Brigadier. He called it his "favourite" in an interview with Doctor Who Magazine in 2009. The DWM staff remembered this by including it in his tribute issue as that month's "The Fact of Fiction".
  • At Doctor Who fan events, Courtney frequently recounted an incident which occurred during shooting of the scene with the revelation of the Brigade Leader and his eyepatch. The scene begins with Courtney having his back to the camera (and to all the other actors), before spinning around in his swivel chair to reveal the Brigade Leader's visage and eyepatch. When the scene was shot, Courtney spun around to discover that all the other actors and crew members were also wearing eyepatches. According to the story, he then proceeded to perform the entire scene as if nothing unusual had occurred. The "eyepatch story" became so closely associated with Courtney that Steven Moffat wrote scenes in which "everybody was wearing an eyepatch" into the 2011 episode The Wedding of River Song as a tribute to Courtney, who had died earlier that year. (DWMSE 31)
  • During the scenes set on the parallel Earth, images (supposedly) of the UK's dictatorial leader are seen on posters. The image used is that of visual effects designer Jack Kine, in homage to the 1954 BBC adaptation of George Orwell's Nineteen Eighty-Four where the face of Big Brother was Head of Television Design Roy Oxley (Kine had worked on the visual effects for that production).
  • Inferno marks the first story in Doctor Who to be set in a parallel universe.
  • The scenes on top of the nuclear reactor in episode two were not easy for Jon Pertwee, as he was afraid of heights. It took him fifteen minutes just to summon up the confidence to film the scene.
  • In episode three, during the chase scene on the parallel Earth, Bessie's bumper gashed open stuntman Alan Chuntz's leg as it passed. The gash was so severe that he had to go to A&E. Barry Letts stated on the DVD commentary that "it was the worst wound [he]'d ever seen" and after Pertwee saw the wound and learned he caused it, he became sick and almost couldn't carry on filming until a few hours later. Jon Pertwee even went as far as buying Chuntz's wife a gift to apologise for the accident.
  • A Doctor Who Unbound story would later touch on a narrative element of this story. According to Sympathy for the Devil — a narrative not part of the Doctor Who universe —research into the possibilities of Stahlman's gas was still ongoing in 1997, the year that the Doctor in that continuity's exile on Earth began.
  • This was the final story to feature the original TARDIS console prop. Having been in use since the show's first episode in 1963, the prop had gradually deteriorated over the years, with numerous bits and pieces falling off or being replaced. After this story aired, the prop was deemed unusable and junked. For the TARDIS console unit's next appearance in The Claws of Axos, a new prop, designed by Kenneth Sharp, was built.

Myths

  • The parallel universe aspect of the story was added to the scripts at the production team's suggestion to ensure that there was sufficient material to fill seven episodes. (Though Terrance Dicks has claimed this in several documentaries, the parallel universe aspect was present as far back as Don Houghton's original story outline. It actually appears to have been the Primords who were added at the production team's suggestion)
  • This was Caroline John's last story as Liz as she was pregnant and could not return for the following season. (Although it is true that the actress was pregnant, Barry Letts was unaware of this when he decided against renewing her contract.)
