The Waters of Mars (TV story)

The Waters of Mars was the first Doctor Who special unrelated in any way to a particular holiday. Mostly a character piece, it showed the extremes to which the Doctor would go when unregulated by either other Time Lords or companions. It continued the "he will knock four times" story arc begun in the previous episode.

It won a 2010 Hugo Award for writers Russell T Davies and Phil Ford. After years of stability at the producer's office, The Waters Of Mars was the fourth episode in a row to be produced by a different person.

Synopsis
Mars, 2059, Bowie Base One. Last recorded message: "Don't drink the water. Don't even touch it. Not one drop."

Plot
The TARDIS arrives on Mars and the Tenth Doctor steps out in his spacesuit, seemingly just to relax and enjoy the landscape. Stumbling across a base inhabited by a team from Earth, the Doctor is detained by a remote-controlled robot called "Gadget" and brought inside. The base commander, Adelaide Brooke, is at first suspicious of the Doctor, but after a tense interrogation, decides to trust him. The Doctor learns that the date is 21 November 2059, and that this is in fact Bowie Base One, the first human outpost on Mars. History has it that on this date, the base was destroyed in a mysterious explosion and Brooke and her crew were all killed. Unwilling to break the laws of time and interfere with a "fixed point" in history, the Doctor decides to leave. However, at the very same moment a crisis is developing: a crewmember, Andy Stone, has been infected by a mysterious life form which takes over his body and causes him to gush copious amounts of water. Maggie Cain, another crew member in his vicinity, screams as Andy growls and attacks her, leaving her unconscious in the biodome corridor. After Ed attempts to establish contact with Andy and Maggie over the comlink and they hear Andy growling and snarling into the comlink, Adelaide confiscates the Doctor's spacesuit, reasoning that he could be responsible for the infection in some way, and orders him to come with her and another crewmember, Tarak Ital, to investigate.

As the Doctor, Adelaide and Tarak walk down the corridor with Gadget, operated by Roman Groom from the central dome, the Doctor asks the famous Adelaide Brooke if the Bowie base one mission was worth everything she sacrificed, to which the Captain replied that Earth was reaching the point of uninhabitability with all the smog and pollution, all of which pushed humanity to the brink of extinction, and that to walk on another planet without any smoke but just infinite sky, yes, it's worth it. The Doctor is greatly impressed and tells Adelaide that she was the woman with starlight in her soul. Adelaide says nothing, but her expression is thoughtful. As they walk down the corridor, Adelaide's torch picks out Maggie's unconscious form, and they race to her. She is still alive and breathing, but has a nasty gash on her head. Tarak calls Yuri Kerenski over the comlink, who arrives with a medi pack for Maggie and a stretcher. Ed also arrives, after realising that only one other person was in the biodome; Officer Andrew Stone, who tells Maggie that the only way this couldn't have been an accident was that Andy has gone berserk. Adelaide dismisses him using rank and security protocol. Steffi checks the growling noise on the diagnostics unit of the computer, and is shocked to discover that the growling was the voice of Andy Stone, calling Adelaide on the comlink to warn her that it seems Andy has gone wild. Adelaide, Tarak and the Doctor step into the dormant biodome, and the Doctor restores the lights with his sonic screwdriver, all of which had been shorted out by the infected Andy. Tarak goes to the left to check the biodome airlock doors, while Adelaide and the Doctor go to the right. Maggie awakens as they walk down the biodome, unsuspectingly carrying the mysterious virus which is hiding in her body, but she has amnesia of the previous occurences. Slightly groggy, she tries to get Yuri to open the door for her to come out, but Yuri refuses, saying a little rest won't hurt. As he turns his back, however, Maggie's features crease into a disapproving frown, indicating that she is not herself anymore......

Tarak is the first to find Andy, who swings round onto him and infects him the virus by pouring water over his head, causing Tarak to mutate into a Flood creature. At that point, in a conversation with colleague Yuri Kerenski, Maggie transforms. The organism occupying her body reveals its desire to reach Earth, a planet rich in water.Yuri is first alerted to her transformation when she speaks in a deep voice distorted by the internal fission 'We should like that world', while gazing at planet Earth on a monitor, and Yuri, stammering in horror, briefly describes what has happened to their comrade, the skin around her mouth has become horrifically cracked and broken as though with a laser beam, her teeth have blackened and she is emitting water in an overwhelming torrent from her mouth, as if she is drowning.

Adelaide, realising the biodome is unsafe, tries and fails to establish contact with Tarak over the comlink, and then she and the Doctor run back through the dome in time to see Tarak transform. While Adelaide points her gun at her infected crew member, the Doctor tries to encourage Andy to take his dripping hand away from Tarak's head. Amazingly, Andy seems to obey, and yanks his hand away from Tarak, who collapses as his mutation is completed. The Doctor then acts friendly and introduces himself to the infected man, but then Tarak flicks his head up and turns to face them, and they are horrified to see that Tarak now looks just like Andy; the skin of his mouth has cracked, his eyes are a dead, white blue, his teeth have gone black and copious water pours from his mouth. The Doctor, realising they have to get away, runs with Adelaide hot on his heels, but then Andy and Tarak run after them back through the dome to the door, whose seals are set at maximum just as Andy fires a thick stream of viral water from his hand onto the door. Not a single drop gets inside, but Andy then steps closer to the door and slams himself against the door.

Ed reaches the medical dome to see Maggie for himself. He is shocked by her appearance and his face shows his fear. Steffi, Mia and Roman look through the medical dome camera at Maggie, and Steffi wonders what she has become. She calls Adelaide over the comlink, begging her to come back, but Adelaide orders Ed to make sure that Maggie is contained. Ed confirms it, then Adelaide orders all the water supplies to be closed down, and also orders the others not to drink the water, saying 'Don't drink the water, don't even touch it, not one drop'. The Doctor examines Andy, who looks at him with his dead blue eyes, and suddenly grins. The Doctor fails to get a response from the creature or his friend standing behind him. Andy then starts examining the door, and the Doctor realises that humans are 60% water, so they are the perfect host for something like a mutating water virus. The Doctor says he has to go, and that he can't stay to see what happens, leaving Adelaide confused.

Suddenly, Andy slams his whole body against the door, making both the Doctor and Adelaide jump. Andy growls at Tarak who then attacks the door by firing water from his mouth into the side, fusing the systems and causing the tortured door to open. The Doctor and Adelaide escape and start running down the corridor back to the central dome, but Andy and Tarak then break out of the biodome doors and race after them. Realising that the infected men can run faster than them, the Doctor sonics Gadget, making him able to move considerably faster, and he and Adelaide hitch a ride on the robot, which causes agony to Roman Groom, the robot's operator. Andy and Tarak, still infected, chase the Doctor, Adelaide and Gadget back to the central dome, but are unable to pursue them any further due to the hardinger seals in the central dome airlocks and are contained in the base's "bio-sphere" section while Maggie is secured in the medical wing. The Doctor, however, is worried about the doors and whether they can protect them from creatures with such power, making a chilling statement 'Water is patient, Adelaide, water just waits. It wears down the clifftops, the mountains, the whole of the world. Water always wins!'

In the medical dome, the Doctor and Adelaide meet the infected Maggie, who just stares at them all, but she suddenly takes an interest in the Doctor when he speaks ancient North Martian to her, Maggie appearing to understand it. The Doctor realises that, looking at Maggie's blackened mouth and cracked skin, that whatever the infection is, it doesn't just live as water, it can produce immense amounts of it. The crew plan to evacuate in an escape shuttle, and the Doctor grimly tells the news to Adelaide that they could be carrying the infection, as they discovered, from Maggie's transformation, that the infection could hide in a human and mutate it at any moment. As the Doctor and Adelaide go to inspect the glacier from which the virus came from, Maggie breaks out of confinement by seeping water into the door and alerts Andy and Tarak in the biodome corridor to the humans' plans by emitting a terrifying alien scream that is heard by the two men over a hundred metres away. The infected men slowly lower their heads and then look towards the Medical dome from which the scream is coming from, then they slowly walk away.

In the dome containing the glacier, the Doctor hypothesises that the virus may have been preserved and imprisoned in the glacier by the Ice Warriors to prevent its spread. However, before they can get to work, Adelaide queries the Doctor on how he knows so much about them. Reluctantly, the Doctor comments that she may have a story to tell, and Adelaide agrees. She says that when she was 10 years old, the sky had changed, as it was the moment when the Earth was snatched by the Daleks, and Adelaide says that she saw a Dalek float down to her window, and it saw her and just stared at her, then flew away. Adelaide says that she knew, someday, she would follow it into the stars. The Doctor and Adelaide work out, through a last message from Andy, that the water was fine to drink until the filter broke and the virus could get into the water supplies. The crew plan to evacuate in an escape shuttle, and the Doctor breaks the news to Adelaide that she must die today, on Mars, if events are to unfold as they should. Adelaide begs him to help but the Doctor insists he cannot interfere, so Adelaide allows him to leave, saying two last words, 'Damn you.'However, as the crew prepare to leave, Andy and Tarak climb the maintenance shafts in the main dome, walk to the centre of the roof of the control centre, fall to their knees and exude more water from their hands and mouths through the girders in the roof, which pours into the room and claims the base's senior technician, Steffi Ehrlich, as she watches a tape left by her two daughters. Then Gadget'S operator, Roman Groom, is infected when a single drop of viral water falls on his cheek. However, he warns the others to run just as he changes. Mia screams and sobs as he is infected, but Yuri restrains her, and so they all make for the shuttle. However, as Ed prepares the shuttle for take-off, Maggie infiltrates the shuttle and blasts water up the shaft into the pilot room, which cascades over Ed's arm, infecting him with the virus. However, just as the infection consumes him, and his eyes turn white-blue, Ed bids Adelaide, Yuri and Mia a final farewell; "See you later" and triggers the shuttle's self-destruct system, which traps the Flood on Mars but leaves the rest of the crew stranded with no means of escape. The Doctor, who narrowly avoids being caught in the blast, is inspired to fight back against Time, as he realises that he is the last Time Lord, and returns to the base to save the crew.

Finding the base falling apart, the Doctor rallies Adelaide, Mia and Yuri and tries to assess the situation. Adelaide insists that the Flood cannot be stopped and the Doctor should save himself, but the Doctor tells of the prophecy regarding his death and states "It doesn't mean right here, right now, cause I don't hear anyone knocking, do you?!". In response, the infected Andy slams his fist against the door three times; the Doctor hatefully shouts back "Three knocks is all you're getting!" and electrifies the door, causing Andy to conduct the electricity, scream with pain, and let go of the door. The Doctor realises that, coming from Mars, the Flood creatures would be very sensitive to heat, reasoning that if it worked against the Ice Warriors, it works against the Flood. He plans to activate the environment controls and boil them. Adelaide reminds him of his assertion that they must die to ensure history unfolds correctly, but the Doctor replies that as the last of the Time Lords, "the laws of Time are mine, and they will obey me!" Suddenly, an explosion rocks the base, destroying its environmental controls. The Doctor states he will reactivate them from outside, only to find his spacesuit destroyed. Refusing to admit defeat, he plans to get a spacesuit from the storage section of Bowie Base, only to find the entire section flooded. At the same time, Maggie heads to the glacier and lets out a deafening shriek that begins to crack the very ice. As the glacier cracks under Maggie's screams, the base's stability begins to collapse; sensing that history will follow its inevitable course, Adelaide activates 'Action 5'; a nuclear device placed at the heart of the base, that will destroy the Flood, but also kill everyone else, infected or not.

The Doctor, realising they have one chance, uses Gadget to roll across the Mars landscape and bring the TARDIS to the base. As time runs out, Maggie continues to wail at the glacier, causing even more ice to crack, and the other infected personnel: Andy, Tarak, Roman and Steffi begin to scream as well, adding their efforts to the Flood's release. Just as the Flood begins to escape the glacier, the TARDIS materialises in the control room, and the survivors get inside, just as the nuclear device explodes, destroying the base and wiping out all the Flood creatures, the explosion unnoticeable from Mars' atmosphere.

The TARDIS materialises outside Adelaide's house on Earth. Mia and Yuri are shocked by their experiences on Mars and by the Doctor's power and depart, bewildered. In a conversation with Adelaide, the Doctor reflects on why he ultimately decided to save her and the others. He argues that the rules of the Time Lords were only valid while their civilisation existed, and that since he is the last of his race he has total authority over time. He proudly declares himself the "Time Lord Victorious" and remarks that with this power he will now be able to save influential figures such as Adelaide as well as "little people" the likes of Yuri and Mia. Berating the Doctor for his new found arrogance: "Who decides how important they are!? I don't care who you are, the Time Lord victorious is wrong!", Adelaide returns home and commits suicide, reverting the changes that the Doctor has made to the timeline.

Only now understanding the full impact of his actions, the Doctor is overcome with horror and realises that there will be a price to pay for his interference. Ood Sigma inexplicably appears in the street, prompting the Doctor to ask him whether he has finally gone too far — whether the time has come for him to die. Unresponsive, Sigma vanishes, and the Doctor staggers back into the TARDIS to the ominous sound of the Cloister Bell. With a defiant "No!", he begins to work the machine's controls.

Individuals

 * Adelaide was 10 years old when the Earth was stolen by the Daleks, and she witnessed one herself.

Earth history

 * Adelaide Brooke says that the last forty years on Earth have been chaos, with massive climate change, ozone degradation, and "the oil apocalypse"; humanity "almost reached extinction" during this period. Andy's obituary mentions "appalling storm conditions" in 2040, and climate change affecting agriculture in 2045.
 * Maggie believes the Doctor may be a Filipino or Spanish astronaut, as the Philippines are rumoured to be building a Mars rocket and Spain have a "space link" that they managed to keep secret. Andy Stone's sister worked for the Spanish space programme. Ed Gold believes the Doctor is from a non-state independent group, referring to the "Branson Inheritance", likely a reference to Richard Branson, a British industrialist who uses his vast wealth to fund commercial space flight.
 * Various lunar missions have been carried out, including ten German missions and Project Pit Stop, establishing a refuelling station on the moon. Mars was landed on in 2041, with Adelaide Brooke as part of the crew. Thirty years after 2059, Brooke's granddaughter Susan will pilot the first lightspeed ship.
 * At least one of the webpages (the one showing Brooke's granddaughter) dates from the 2080s or later, suggesting the Internet still exists in some form in the late 21st century.
 * In 2059 flares emanating from the Solar System's Sun are preventing clear communications between Earth and Mars.
 * Although its name is not given in dialogue, one of the webpages shown on screen indicates that the name of the spacecraft that brought Brooke's crew to Mars and that of the vessel Ed Gold is forced to destroy, is Apollo 34.
 * NASA sent the Space probe Phoenix to Mars, where it discovered liquid water.

Locations

 * Bowie Base One is Earth's first off-world colony.
 * Bowie Base One is located on Mars in the Gusev Crater.
 * The colony's plantation grows, according to the Doctor, the first vegetation seen on Mars for 10,000 years.
 * The Republic of Dagestan exists by the Caspian Sea, apparently a reference to the part of Russian Federation.

Species

 * The Doctor mentions the Ice Warriors and suggests that they may have frozen the Flood. The Ice Warriors' present apparent absence from Mars goes unexplained, though the implication is that they departed Mars after discovering and freezing the Flood to prevent their race from being infected by it.

Robots

 * The Doctor said that he hates "funny robots" but notes that he'd be okay with a robot dog.
 * Gadget was built by Roman Groom using parts from the drones that constructed Bowie Base One.

The TARDIS

 * Whilst on Earth, the Cloister Bell is audible while the Doctor stands alone in the TARDIS.

Story notes

 * This story was initially envisaged as a Christmas special, several festive references remain, such as the crew on Mars preparing for Christmas dinner, and it snowing when the Doctor arrives back on Earth as he exclaims how he likes snow.
 * This story was originally entitled; Red Christmas.
 * Lindsay Duncan became the oldest actress, and briefly the oldest individual, to be cast in the companion role (although like several before her, her official status as a companion will remain debatable). As Bernard Cribbins took on the companion role in DW: The End of Time, he became the oldest male actor and oldest individual in this role.
 * The episode ends with a dedication to Barry Letts. The former Doctor Who producer and writer had died several weeks before the broadcast.
 * Phil Ford's original draft was called "A Midwinter's Tale", and was a sword and sorcery tale about an alien princess coming to Earth to be married. It ended with a long chase sequence in secret tunnels beneath Buckingham Palace.
 * When initially sketching out the story, Davies considered Helen Mirren as a potential actress to play the character that eventually became Adelaide. In an early draft, the character that became Adelaide was Russian, but this was changed when, still thinking of Mirren as a potential guest star, Davies felt it would have been too close to the character played by Mirren in the film 2010: The Year We Make Contact. (REF: Doctor Who: The Writer's Tale - The Final Chapter)
 * In a deleted scene, the Doctor suggested that the Ice Warriors were unable to fully defeat the Flood and fled the planet as a result, explaining their absence
 * This story won the 2010 Hugo Award in the category of Best Dramatic Presentation, Short Form.
 * On November 21, 2009 (only six days after the initial broadcast, and exactly 50 years before the date the episode takes place in), David Tennant surpassed Jon Pertwee as the actor with the second-longest tenure as the Doctor. Jon Pertwee was the Doctor for 1,617 days, and following The End of Time David Tennant was the Doctor a total of 1,658 days.
 * The Waters of Mars is the last Doctor Who story released on DVD to include a "Next Time..." trail for a following episode, and one of only two Bluray releases, along with DW: Planet of the Dead, to include a "Next Time..." trail. The End of Time did not include such trailers even at broadcast, and while most episodes from series 5 were broadcast with "Next Time..." trail they were excised from the DVD and Bluray release.
 * "Bowie Base One" has a layout similar to Moonbase from Gerry Anderson's TV series "UFO".
 * "What the hell is that noise?" the sound is a Proximity Alarm, used in the Movie: "2001, a Space Odyssey"
 * "Bowie Base One" is a reference to David Bowie's song "Life on Mars".

Ratings

 * 15th November 2009 - 10.32 Milion
 * 33.9% of TV share

Filming locations

 * Victoria Place, Newport
 * National Botanic Gardens of Wales, Carmarthenshire
 * Taff's Well quarry, Cardiff, Wales

Production errors

 * The first of the web pages brought up in the episode claims that Adelaide had a seven-strong crew with her, though there were 9 people on-site not counting the Doctor.
 * In Yuri Kerenski's profile near the beginning of the episode, Tarak Ital's name is incorrectly spelt as "Tarek".
 * When it is revealed that Maggie is one of the creatures, the outer shot shows her hair back while in the closer shot, it is around her face.
 * When the Doctor opens Adelaide's door, the door unlocks and is opened till it is ajar. When Adelaide approaches the door however, it is closed over.
 * While Yuri is watching a video of his brother, during the close up of Yuri, in the background, Maggie's mouth seems to be grey and cracked the same as the Flood. When the scene returns to a shot of Maggie, her mouth is normal. This is repeated twice until it shows Maggie throwing her head back.
 * When young Adelaide sees the Dalek its eyestalk lights are permanently on
 * When Susie Fontana Brooke's website is brought up, it shows her crew as identical as that of Bowie Base One. This is likely a typographical error, saying "Brookes team consits of" when it should have read "Brooke's team consisted of", meaning the article referred to Adelaide's team, not Susan's.
 * On Adelaide's web page there is a line of text at the top that states the page was updated on Thursday, 22 November 2059, in actuality 22 November 2059 falls on Saturday.

Continuity

 * The Doctor speaks partially of the events in DW: The Fires of Pompeii.
 * There is a flashback to an event that occurred during the timeframe of DW: The Stolen Earth / Journey's End, which includes a cameo appearance by a Dalek.
 * The spacesuit the Doctor wore was the same suit from DW: The Impossible Planet / The Satan Pit and similar to the one he wore in 42.
 * Mars appears not to have much of an atmosphere, however NA: The Dying Days suggests otherwise.
 * Carmen's prophecy "he will knock four times" is mentioned from DW: Planet of the Dead.
 * Sound clips of the Doctor talking about the Time Lords and The Time War are used from DW: Rise of the Cybermen, Doomsday, Gridlock, Utopia / The Sound of Drums / Last of the Time Lords.
 * The Doctor says that heat worked against the Ice Warriors, a reference to DW: The Seeds of Death and DW: The Monster of Peladon.
 * The Doctor also used the tactic of electrifying bulkhead doors in DW: The Ark in Space
