A running man heads for the TARDIS: Captain Jack Harkness. He manages to grab the outside just as the Doctor dematerializes, and Jack’s presence somehow disrupts the sequence. The TARDIS accelerates into the distant future, to the end of the universe, while Jack holds on outside.
And in that future, a savage tribe of people on the planet Malcassairo sense humans in their vicinity.The savages, the Futurekind, are hunting down humans. Professor Yana and his insectoid companion Chantho sense the human’s presence but realize there’s nothing they can do. Yana is under pressure to produce results, but seems to have problems as he hears a distant drumbeat inside his head. They find something on their sensors: the TARDIS.The Doctor warns that even the Time Lords haven’t come this far into the future but insists on going outside and seeing what there is to see. They find Jack Harkness outside, seemingly dead, but he immediately revives. Jack isn’t happy with the fact the Doctor left him on the Satellite 5, and wants to know what happened with Rose. In return, the Doctor is oddly hostile toward Harkness. Jack is happy to know that Rose is still alive. He explains that he had a vortex manipulator and was able to escape the Satellite but was stranded in the 19th century. He waited for over a hundred years trying to locate the Doctor when he arrived at the rift to refuel.
They find a hive city and spot the human being pursued by the Futurekind. The Doctor, Jack, and Martha come to his aid but the Futurekind surround them. The human directs them to a launch silo and they get to the gate where they prove they’re not mutated to the guards. The guards drive off the Futurekind and assure them that they can be taken to Utopia.
Professor Yana is informed of the new arrivals, including the fact that one is a Doctor. They find a silo containing a gigantic spacecraft, and Professor Yana introduces himself, happy to find a fellow scientific genius. None of them aware that one of the base occupants is secretly a mutated Futurekind. Martha discovers that Jack has a hand in a tube: the Doctor’s hand (from “The Christmas Invasion”). Jack has been using it as a Doctor detector to find him. The Doctor identifies himself as a Time Lord and Chantho identifies herself as the last of the Conglomerate, the race that originally inhabited the planet.
Yana explains that a point in space transmitted the message “Utopia” throughout the universe, calling them to a barren point in space. A project to find Utopia has been underway for thousands of years, but Yana is again briefly overwhelmed by the sound of drums in his head. The Doctor provides a means to get the rocket working and everyone prepares to leave, unaware of the Futurekind infiltrator.
The Doctor and Professor Yana chat and Yana admits his title is purely honorary. The Doctor notes that Yana will have to stay behind to launch the rocket and the Professor admits Chantho won’t leave him behind so he’s lying to her. However, the base guards have found the TARDIS, which triggers another round of drumbeats with Yana. The Doctor uses the TARDIS to power up the system and Yana confesses his problem to the Doctor. Lieutenant Atillo, head of security, sends a man in to get the power couplings. The chamber is heavily irradiated but safe as long as they hold back the stet radiation. However, the Futurekind infiltrator sabotages the systems and the man is killed when they can’t hold the radiation stable. Jack tries to break the connection but is electrocuted, and the Doctor stops Martha’s efforts to revive him. Jack comes back to life and the Doctor realizes they need him to get into the chamber and get the couplings.
As Jack goes in, he asks the Doctor how long he’s known and the Doctor admits he’s known for some time. Jack then accesses the couplings while Martha explains to Yana that the Doctor travels in time. Yana examines the TARDIS as its name echoes through his mind.
Inside the chamber, Jack discusses the fact that he is now effectively immortal, and the Doctor knew all the time. The Doctor left him behind because of an instinctive Time Lord reaction to the fact Jack is a fixed point in time and space, and even the TARDIS reacted against him. The Doctor explains that Rose gave Jack immortality when she revived Jack after his encounter with the Daleks. With Rose stripped of the power and trapped on a parallel world, there’s no way to restore Jack to normal. As they discuss regeneration, the words seem to stir memories in Professor Yana. He shows Martha a watch… the same type of watch that the Doctor carried when he changed himself to human. Yana explains he was an orphan and can’t get the watch open. Martha nervously backs away and goes to tell the Doctor of what she’s discovered.
Jack frees the power couplings and a countdown begins as he works with the Doctor to make sure the ship launches. Martha explains that Yana has the same watch that the Doctor did, and it changes a Time Lord into a human. The Doctor wonders which Time Lord Yana might be, and is concerned that now Yana can see it despite the perception filter. Yana begins to hear voices in his head, commanding him to open the watch, while Chantho tries to reassure him. The Doctor initiates the launch while Yana considers the watch… and opens it. And the Doctor realizes that the Face of Bode’s last words--“You Are Not Alone”--are an anagram of Yana.
Confirming the ship has lifted off, the Doctor heads for Yana’s lab but the Professor cuts off the power, opening the gates to the Futurekind. The Doctor cuts his way through the security doors while a despairing Chantho pulls a gun on Yana for destroying their work. He takes an electrical cable and advances on herm, furious that she never told him of the watch. Yana announces that “the Professor” was a disguise and that he is truly… the Master.
The Doctor, Jack, and Martha make their way through the corridors to the lab while the Master takes the Doctor’s hand and the data file on Utopia. He prepares to enter the TARDIS after killing Chantho, but she fires one final shot and mortally wounds him. The Master enters the TARDIS and locks it behind him, then staggers to the console. Jack and Martha try to hold the doors against the Futurekind while the Master resolves to be young and strong… then regenerates into a new form. The Master announces himself to the Doctor as Martha recognizes his voice. The Doctor tires to interfere with the TARDIS power systems using his sonic screwdriver but the Master dematerializes the TARDIS and leaves them stranded…
The Doctor, Martha, and Jack arrive in an alleyway in modern-day London and the Doctor explains he was able to fix Jack’s time manipulator to bring them away from the future. The Doctor believes he’ll know the Master as soon as he sees him, but they see a news broadcast of England’s new prime minister: Howard Saxon, the Master.
The Master and his new human wife Lucy are going into his new office when Tish Jones, who is working for him, wants to know what she should do. The Master simply tells her to look attractive then goes into his first meeting and is unconcerned about the seriousness of the situation. He insults his cabinet members and dismisses them as traitors. He then dons a gas mask and releases gas mask into the room, killing them all.
Martha takes the Doctor and Jack back to her apartment, and she discovers that Tish is working for the Master. Vivian Rook, a newspaper columnist, arrives to speak with Lucy Saxon. Once Rook dismisses Tish, she warns Lucy that her husband isn’t who he says he is, and his entire background is invented. He only reappeared after Harriet Jones was removed from office, and after his success with the Archangel project, a mobile cell phone network. Lucy chooses to remain faithful and Howard Saxon comes in. He admits everything she’s found out is true, proclaims that he is the Master, and causes several metal spheres to appear. He and Lucy step out of the room as the spheres brutally kill Rook.
The Doctor explains that he locked the TARDIS in so it could only travel between the distant future of Utopia and the 21st century. Both Martha and Jack were going to vote for Saxon, but had no idea why. The Doctor notices Martha tapping rhythmically but before he can follow it up, Saxon broadcasts a new speech announcing he has allied with the metal spheres, an alien race known as the Toclafane. He promises that the human race will assume their righteous place in the universe. The Doctor realizes a bomb has bee attached to the back of Martha’s TV and gets them out just before it blows up. She calls her mother, who says she’s resolving matters with her ex-husband and asks Martha to come meet them. Saxon’s men are listening in and her father Clive blurts out it’s a trap. He’s taken away while Martha drives the Doctor and Jack to the apartment. She tries to call Tish who is arrested. They get to the apartment but a mysterious blonde woman opens fire on them and they’re forced to drive away as the rest of Martha’s family is arrested.
They ditch the car and Martha calls her brother Leo. Saxon is listening in and notes he’ll find her no matter where she hides. The Doctor takes the phone and verbally spars with the Doctor, noting the Toclafane were a Gallifreyan bogeyman. The Doctor explains that Gallifrey is gone, destroyed in the Time War. The Master explains he was resurrected as the perfect warrior for the Time Lords, but he ran when the Dalek Emperor revealed the Cruciform, making himself human to disguise his existence. The Doctor tries to persuade him to take their fight away from Earth, but the Master refuses and mentions the “drumming” inside his head. The Doctor notices everyone is drumming to the same rhythm, while the Master announces that Martha, Jack, and the Doctor have all been labeled as terrorists. Jack’s “gang” have been sent off to the Himalayas so he’ll get no help from them. The Doctor realizes the Master is watching them on the surveillance cameras, and the Master tells them to run for their lives.
One of the Toclafane appears before the Master and asks if “the Machine” is ready. The Master informs it that it will reach critical the next morning. The Toclafane speaks of an approaching darkness, but the Master is unconcerned.
The Doctor, Martha, and Jack hide in an abandoned building, and the Doctor explains that young Time Lords are required to look into the Time Vortex. Some run away, and a few go mad… and the Master went mad. Jack explains that he rebuilt Torchwood after the Canary Pier incident, so that they were no longer hostile toward the Doctor. Vivien Rook has sent Jack an electronic file warning against Howard Saxon and the Archangel orbital network. The Doctor realizes the Master is using the system to send a rhythmic four-beat pattern to subconsciously force them to support him. The Doctor takes three TRDIS keys and reprograms them to release a subliminal signal to let them blend in as long as they don’t draw attentions to themselves.
Air Force 1 lands in England as U.S. President-Elect Winters arrives to speak with the Master. Winters orders him to stand down so UNIT can take control of the alien contact situation. The Master seems unconcerned and Winters orders them to have the meeting moved to a UNIT aircraft carrier, the Valiant. The Doctor, Jack, and Martha arrive and inconspicuously watch, and the Master seems unconcerned as long as the meeting is broadcast worldwide. After Winters leaves, the Master has Martha’s family transferred but the Doctor insists that he deal with the Master without killing him.
Jack uses his time manipulator to teleport them to the Valiant the next morning, hovering far above the surface. The Doctor seems to hear something and takes them to the TARDIS. Going in, he finds the control console cannibalized and rebuilt into a Paradox Machine.
Winters prepares for first contact while the Doctor explains that the Paradox Machine has enough power to destroy the solar system. Winters broadcasts worldwide while the Doctor tries to get close to the Master. If he can put one of the keys around the Master’s neck, the world will see him for what he really is. The Toclafane appear and demand to know where the Master is. He reveals himself and has the Toclafane kill Winters, then has his men capture the Doctor. The Master boasts he was immune to the perception filters then uses a laser screwdriver to temporarily kill Jack. The Doctor tries to get through to him but the Master talks about Lazarus’ genetic manipulation device. The Master has concentrated the technology into his laser screwdriver, along with the Doctor’s biological data code from the hand. He uses the laser screwdriver on the Doctor, aging him a hundred years. Jack and Martha look on as the aged Doctor crouches helplessly.
The Master has Martha’s family brought in, and the Doctor demands to know who the Toclafane are, but the Master declines. The aliens demand to know if the machine is finished and the Master announces its time. He activates the Paradox Machine in the TARDIS and a rift opens aboard the Valiant and six billion Toclafane pour out. They travel across the Earth, wiping out one-tenth of the population. Martha has no choice but to leave the Doctor and teleport away using Jack’s time manipulator. She looks on as the Toclafane decimate the planet, and resolves that she will return. The Master and Lucy hold the Doctor between them, forcing him to confront the slaughter below.
One year after the Master has taken control of the planet, Martha returns to England by boat and meets with Thomas, one of the underground fighters. She needs to meet with Professor Docherty, and uses the TARDIS key to conceal her self via the perception filter.
The Master takes the aged Doctor to the window of the Valiant and boasts of how he will use the Toclafane to recreate the world as the new Time Lord empire. The Master knows of Martha’ return and wants to know what the Doctor told her a year ago. He tells his staff to prepare for launch in 24 hours.
Elsewhere on the Valiant, Tish is sent to bring food for the imprisoned Jack, while Martha makes her way cross-country with Thomas. They find a manufacturing facility designed to build spaceships to launch a military assault across the universe.
Jack manages to pull himself free while the Jones family strike out and the Doctor manages to grab the Master’s laser screwdriver. The Master is unimpressed and it becomes clear that he was prepared, as his soldiers gun down Jack. The Master reveals his screwdriver has isomorphic controls and the Doctor can’t use them. He has the Jones family taken away.
Martha and Thomas get to Docherty just as the Master makes a speech to the world. He dismisses the rumors of Martha as some kind of savior, and shows the Doctor on-screen. The Master then stops the Doctor from regenerating and ages him another 900 years, reducing him to a dwarfed frail creature. Martha refuses to be intimidated, insisting that the Doctor is still alive and taking hope from it.
Docherty reveals that the Master’s telepathic signals are still keeping Earth from mounting a successful resistance against them. Martha believes that the key is the Toclafane, and that one was destroyed by lightning in South Africa. She gives the readings to Docherty, who determines she can recreate the conditions. Thomas goes out and lures in a Toclafane sphere, and Docherty and Martha capture it with an electrical trap and start to take it apart.
The Master and his wife Lucy go to see the Doctor, now kept in a cage, to boast of how their empire will begin the next day. The Master is still obsessed with the drum beat, which he has heard ever since he looked into the vortex and believes are the drums of war.
Docherty opens the sphere and finds that it contains a human head. The head is still alive and speaks to Martha Jones directly. It reveals that it has the memories of Creet, the child that Martha talked to before leaving for Utopia.
Aboard the Valiant, the Master has Lucy described the future of Utopia to the Doctor, from when the Master took her there. Martha realizes that the coordinates are locked between the year 100 trillion and the 21st century, so the Master went to Utopia. The survivors found nothing, cannibalized themselves, and gave themselves the mentality of children. The Master brought them back to the 21st century and used his Paradox Machine to avoid the fact of the Toclafane going back in time to kill their own ancestors. The Toclafane explain that they wish to help the Master build his new empire, just for the fun of it.
Martha explains to Docherty that the Doctor told her of a weapon that is capable of killing a Time Lord despite his regenerative abilities. Torchwood and UNIT created such a weapon but it needs four key chemicals and she only has three. The components were scattered across the world and Martha has spent the last year assembling them. The last component is in an old UNIT base in London so she and Thomas head out to get the last component. As Martha leaves, Docherty warns that she doesn’t look like a killer.
Martha and Thomas make their way through the streets of Bexley to another underground fighter who is sheltering refugees. They are unaware that Docherty is secretly contacting the Master and bargaining her knowledge for the life of her son. Meanwhile, Martha speaks to the refugees and inspires them with tales of her travel and how she is no legend, but the Doctor is the one everyone should think of. The Master himself sets foot on Earth and arrives with his human and Toclafane security forces. He calls out to Martha to surrender and she steps out, removing the TARDIS key. He forces Martha to turn over the weapon so he can destroy it. He prepares to kill Martha but Thomas charges out and the Master kills him. He then decides to take Martha to the Doctor so his rival can see his companion killed before him.
Aboard the Valiant, the Master takes the vortex manipulator from Martha and then prepares to order the launch of his fleet. The Doctor, Martha, Jack, and the Jones family are forced to look on but Martha starts laughing. She reveals the gun was a fiction that she and the Doctor set up, and they knew about Docherty’s son and how the professor would give her away. As the countdown hits 1 minute to launch, Martha explains of how she traveled the world to spread the story of the Doctor and to think of one word, one thought, at one specific time. The Archangel network’s telepathic field would pick up the one though, and the Doctor has spent the last year tuning into the telepathic field. The Doctor absorbs the telepathic energy and reverses the aging process. The Master opens fire on him but his laser blasts are useless. When he tries to kill Jack and the others, the Doctor telekinetically takes away his laser screwdriver. The Doctor advances on him… and says “I forgive you.”
The Toclafane realize something is amiss, while the Master uses the vortex manipulator to teleport himself and Doctor to one of the shipbuilding yards. The Master reveals he has a black hole converter and will use it to trigger the self-destruct of every ship on the world. Jack and the soldiers go to the TARDIS to destroy the Paradox Machine, fighting past the Toclafane.. The Doctor points out the Master wouldn’t kill himself even if he could take Earth along and the Master turns over his remote. Jack gets inside the TARDIS and destroys the Paradox Machine, and Earth is shaken by the realignment of timelines. The Doctor teleports the Master back to the Valiant and time reverses itself a year. Other then those aboard the Valiant at the moment of realignment, no one will remember the Master’s conquest of Earth. They handcuff the Master but the Doctor insists that the Master is his responsibility and will imprison him in the TARDIS. However, Lucy Saxon guns the Master down. The Doctor holds him but the Master refuses to regenerate so as to avoid a prisoner’s eternal fate, and declares that he’s won. Then he wonders if the drumming will finally stop… and dies. The Doctor cremates his oldest rival’s body and leaves… unaware of a feminine hand that sort through the ashes and takes the Master’s ring.
The Doctor, Martha, and Jack go to Cardiff and Jack takes off, refusing to go with the Doctor. He’s concerned about his Torchwood team and plans to find them, although the Doctor relieves him of his vortex manipulator. The Doctor warns that Jack will live forever, and as Jack leaves he mentions that he was once nicknamed “The Face of Boe,” leaving the Doctor and Martha to wonder…
The Doctor has completed repairs on the TARDIS and has his severed hand safely on-board. He waits outside the Jones house as the family is reunited, then Martha comes into the TARDIS… to tell the Doctor she is staying behind. She plans to earn her doctorate and look after her family. She gives the Doctor her phone in case he needs to contact her, and admits that when someone feels unrequited love, it’s time to walk away. She leaves once more and the TARDIS sets the controls… as the prow of the Titanic crashes through the wall.
