The Impossible Planet (TV story)

The Impossible Planet was the eighth episode of the second series of Doctor Who.

Synopsis
The TARDIS lands in a base on Krop Tor, a planet which orbits the black hole K37 Gem 5 without falling into it, a circumstance so inexplicable that even the Doctor cannot understand it. The base crew are drilling to the centre of the planet, to discover the power source which keeps it in a stable orbit around the black hole. But an ancient evil is there too. And he is awake.

Plot
The TARDIS materialises inside a "Sanctuary Base" meant for deep-space expeditions. The Doctor and Rose discover an inscription scribbled on the station wall which the TARDIS is unable to translate.

After a slight misunderstanding when first meeting the Ood, a docile race of empathic servants who work on the station, the travelers meet the crew of the base, led by acting Captain Zachary Cross Flane. Then an earthquake occurs and they all have to take cover. Afterwards, the crew is introduced by Science Officer Ida Scott and includes, Head of Security John Jefferson, trainee maintance officer, Scooti Manista, and archeologist Toby Zed. They are on an expedition on an anomalous planet in orbit around a black hole. The Doctor realises that it is impossible for the planet, which is called Krop Tor, to be in geostationary orbit around the black hole, as it should be pulled in like the star systems around it are. He calculates that it would take a phenomenal amount of power (Six to the power of six for six seconds) to generate the huge gravity funnel stabilising its orbit. The funnel is not a natural phenomenon, and the crew is drilling ten miles underground to the core of the planet in hopes of finding the power source and using it. The origin of the power source is an ancient civilisation that had been on Krop Tor, and the inscription on the wall is a transcription of a stone tablet found on the planet.

The Doctor soon discovers that storage sections 5 to 8 had collapsed as a result of the earthquake-like tremor they had experienced moments after their arrival, dropping the TARDIS, which had been in Storage 6, into a crevasse. With no resources to divert the drilling, Rose and the Doctor are stranded.

It isn't long before a malevolent presence begins to make itself known. Strange messages about the Beast awaking to make war against God emanate from the Ood's translation spheres and the base computer's speakers. Toby begins to hear voices just before he is possessed by the Beast. Then the crew and travellers watch the Scarlet system get eaten by the black hole. Then Rose gets a strange message on her phone and Toby wakes up. Danny, the Doctor, and Rose all discover the Ood acting up and saying weird things.

While the Ood are acting up Scooti hops into Toby's room. She tells him that she has his expenditure. However she soon notices that the room is empty and walks over to the desk. There she puts the file down. The computer then announces the opening of Door 41. Scooti freezes with a confused look on her face. Then as she turns around the computer announces the closing of Door 41. She turns back around with the lamp light from the deck hitting her face. She now is very perturbed. She mutters "41.." silently. Then she realizes that something is wrong. She then turns and dashes out of the room down the hallway.

Scooti then reappears coming out of Door 40. She lets the door close behind her as she rushes to Door 41. There she activates the panel by the door. Scooti first asks if the computer opened and closed Door 41. The computer confirms this. She then explains that it is the nightshift and the they aren't allowed outside. After this she asks if someone went out side. The computer confirms this. She then asks who it was. The computer say that it can't confirm. Scooti soon comes up with an idea. She asks whose space suit has been logged out. The computer then says that no spacesuit had been logged out. Scooti responded by saying that nobody could go out there without a spacesuit. Fed up with the computer she activated her wrist radio. She attempts to contact Zach and says that there is probably a breakdown on Door 41. However the radio crackles up and dies. She yells at the radio to call Zach. She then returns to the computer and asks it to find what's wrong with the radio. It however reports nothing is wrong. Scooti now rather angry yelled at the computer to tell her who went outside. The computer however responds "He is awake". This shocked the young woman rather violently. She asks what the computer says. It then repeats itself. She then demands to know what that meant. It responds with "He who bathes in the black sun" She then pushes away from the computer frightened. She stares at the door for a moment. Then down the hall a viewport opens and a curious Scooti walks over there.

Scooti arrives at the window just as it finishes opening. Out there on the barren surface she sees Toby, amazingly without a spacesuit and somehow surviving. Toby's back is to the window and Scooti's eyes widen in shock at the sight. Toby then turns around. He then spots Scooti and grins evilly back at her. A surprised Scooti mutters Toby's name in complete shock. She then says "but there's no air, there's no..." However Toby cuts her off. He nods as she says that still with that grin. He then raises his hand and begins waving it beckoning her to him. Scooti helpless to refuse raises her arm towards him. Scooti appears to be completely hypnotized by Toby's power. This continues for a moment. Toby continues beckoning her as Scooti continues reaching out to him. Meanwhile her eyes continued to soften and get moist as if to break out crying. However she notices her arm and brings it down to her side. She then yells at Toby to stop and ended with a pleading eyes with her eyes still moist an very much frightened by what Toby managed to do to her. Toby's grin disappears and is replaced by a vicious glare. He then clenches his fist. A white cloud appears on the window as sounds of glass breaking sound throughout the corridor. Scooti still disturbed frantically searches for the source. Then a crack appears on the window between her and the deadly vaccuum. She then gasps in fear. She now realizes Toby intends to murder her.

Scooti quickly turns and races down the hall to door 40. She screeches at the door for it to open. However Toby has sealed all the doors, trapping the young maintenances officer. She then yells frantically at the door to open. It however coldly denies her. Meanwhile the cracks on the window continued to widen. Scooti, looking at the window, screams and tuggs at the door to open. She is scared out of her mind by this point The door ignores the woman and the cracks contue to widen with them now almost completely covering the glass. Scooti is pretty much crying and begging to be let go by this point. Her face becomes twisted with complete terrors. Her once young and energetic eyes become completely fearful. She continues screaming at the door to give her passage. She was tugging so hard that her hair was flying all over her face. She was begging to scream another round at the door to open. Unfortunately, however, her time ran out. Toby completely unclenched his hand. The window explodes from the pressure. Air rushes out of the base. Scooti is still tugging at the door as this happens. Her fingers are harshly torn away from the door that could allow her to survive screaming. She despirately tries to reach for the handle again. However the rushing air denies her this. She flies down the hall and out the window screaming, kicking, and crying to her death in the dark vacuum of space and to Toby, her murderer.

The base began to shake violently and Zach ordered them to evacuate. Danny, Rose, and the Doctor race to meet Jefferson, Ida, the security guards, and the now unpossessed Toby get through the door. Jefferson then closes the door sealing the breach. Zach then asks if everyone was all right. Jefferson then reports that everyone is there except Scooti. Jefferson then calls for Scooti on his radio. However he gets no answer. He then uses her full name and orders her to answer. Zach then tells them she is alright and that her biochip located her in Habitation 3. Jefferson and Ida breathe in relief. They then go down to search for Scooti while the Doctor and Rose tend to Toby.

When Toby, Rose, and the Doctor enter the habitation they find the searchers looking frantically. Ida is clling all the habitations looking for Scooti. Jefferson then reports that Scooti is still missing while Zach continues by saying that her biochip says she is in Habitation 3. Then the Doctor sadly sys he found her. Scooti was floating beyond the wind with her hair flying and her skin pale. Jefferson reports her death while Zach looks sorrowful. Ida then goes over to the control to close the overhead saying how she was only twenty years old. Scooti floats away towards the black hole spinning as the door closes. Jefferson recites a poem as this occurs.

The team finally manages to drill down to the core of the planet. The Doctor and Ida journey down the mine shaft and into a massive cavern with ancient giant sculptures along its walls. They head for the power source, guided by sensor readings, and find a large circular disk set in the floor of the cavern, which the Doctor suspects is a trap door of some sort. The edge of the disk is also covered with inscriptions.

Meanwhile in the base, the Ood's telepathic fields rise dangerously to Basic 100, which is high enough to induce brain death, but they are obviously still alive. Finally the beast makes itself known through Toby before seemingly transferring itself to the Ood. The Ood identify themselves as the Legion of the Beast and begin to advance on the crew members, including Rose. Finally, the Doctor and Ida stand before a seal on the cavern ground, which then slids open, to a black chasm. A voice booms out from beneath it, stating, "The pit is open, and I am free!"

 * The episode contains a number of references to the popular Doom series. In particular, the door opening and closing sounds from the first two games are occasionally used (especially noticeable when Toby goes searching for the "voices" distracting him from his archeological findings).
 * The Doctor calculated that the power needed was six to the power of six every six seconds, a reference to 666, the supposed number of the Beast as mentioned in the Biblical book of Revelations.
 * Before the Ood, the production team had considered Raxacoricofallapatorians being the servants on Sanctuary Base 6.

International broadcast
When aired by the Canadian Broadcasting Corporation in late 2006, this episode was considered a mid-season cliffhanger, with The Satan Pit and the rest of the season not airing until early 2007, after a hiatus of several months. At the time the CBC made this decision a trend had developed among North American networks to insert lengthy (sometimes months-long) breaks during the November-January period.
