Has radical thinker Damien Stephens simply sold out , or does he have a more sinister agenda ? The Doctor has detected a mysterious energy reading . Could it be that the most evil creatures in the universe have returned to claim ultimate victory once and for all ? Plot . Part 1 . An astronaut named Damien Stephens is about to make a spacewalk from his shuttle to a base on the moon — but his vitals are not right . Nevertheless he plunges ahead . In the TARDIS , the Doctor and Leela are preparing to land in 21st - century London . Leela has dressed for the occasion , at the Doctor ’ s direction , but the TARDIS ’ s sensors indicate something is not right about their destination . The Doctor lands them in the year 2025 ; for once they are noticed immediately , but the first observer they encounter is surprisingly nonplussed . The man indicates that a protest is about to take place , however , intriguing the Doctor , who takes Leela to watch . Aboard the moonbase , Stephens arrives and meets crew members Lydia Harding and Kevin Winston , who have made some minor adjustments to the control systems . Stephens is noticeably tired , and asks for his quarters to rest before the system ’ s test run . As he sleeps , he hears strange , mechanised voices in his head . Lydia and Kevin discuss Stephens ’ strange behaviour , and Lydia persuades Kevin to illegally access the security camera in Stephens ’ quarters so they can monitor his health . They find him thrashing and mumbling in his sleep — “ I must obey ! ” . The system mysteriously shuts off . Stephens finds himself transported back to his office in GlobeSphere Corporation ’ s headquarters , where he is confronted by Daleks . Shortly afterward , Lydia finds Stephens in his quarters , refreshed and ready to begin the test . The Doctor and Leela find the protest , which includes thousands of people , all of whom are protesting the treachery of “ Globesphere ” , the GlobeSphere Corporation . The sight of a large holographic screen makes the Doctor realises he has landed in the wrong time again ; he was aiming for 2015 , but has brought them to 2025 . He locates an access terminal for the holographic internet ; it doesn ’ t recognise him at first , but he uses his sonic screwdriver to gain access . He researches GlobeSphere , and learns that the date is 30 January 2025 . The Earth , it seems , is in the grip of an energy crisis — but GlobeSphere , under Damien Stephens ’ leadership , intends to solve it . The Doctor is distracted by an announcement from the protest — one Jack Coulson is about to take the stage . Coulson ’ s speech takes place in front of the National Gallery , which now has a huge energy receiver on its roof . Coulson ’ s speech is primarily economic , decrying the increased prices that are projected to accompany the transition to GlobeSphere ’ s new energy source , and the shortages that will result in the meantime , which may cause many deaths . Just before the crowd can become a mob , a private security force arrives to disperse the crowd , and the crowd turns to conflict , forcing the Doctor and Leela to separate . Leela is arrested by one of the security officers , whom she finds she is unable to hurt despite her best efforts . The Doctor , meanwhile , locates Coulson and shows him an energy reading coming from the National Gallery ; he escorts Coulson away from the scene . Leela is taken for processing , but she is unable to answer her captor ’ s questions , and finds that he behaves as though drugged . The man uses soundwaves to temporarily incapacitate her . A security scan reveals that she is a time traveller ; and the men — the Robomen , to be precise — report it to the Daleks . She is taken before the Daleks , who use a cerebral probe on her to gain more information . They question her about her time travel and history ; but she is mostly able to resist at first . However , she is unable to avoid revealing that she is with the Doctor . Meanwhile , the Doctor talks with Coulson about his history with Stephens ; they used to be partners , until Stephens abruptly went off on his own to found GlobeSphere . Stephens ’ advancements are brilliant , but perhaps too brilliant ; in their past , Coulson was the intelligent one , while Stephens was the radical . Further , Stephens gave up his radicalism when he founded GlobeSphere . A news dispatch reveals that the protest has been dispersed . The Doctor decides to infiltrate GlobeSphere in search of Leela and the source of the anomalous readings . He gets Coulson inside the National Gallery via a WWII - era evacuation tunnel . He determines the energy readings are anomalously high for this era ; and Coulson tells him the first test of the system is expected to start at any time . At the same time , the Daleks detect their entry , and conclude the Doctor is on the scene . The test of the energy transmission system commences . On Earth , the Doctor hears the Daleks announce his presence to their troops in the building , and he realises the energy readings are consistent with a Dalek timeship . On the moon , Kevin realises the energy levels are far too high , much higher than anticipated ; but Stephens assures them it is according to plan . Kevin and Lydia are not convinced ; and suddenly a transmission comes through . The Daleks congratulate Stephens on doing well , and announce the beginning of the destruction of the human race . Part 2 . Coulson is shocked to learn a little of the alien origins of the Daleks ; but there is no time to discuss it . The Doctor and Coulson witness the Robomen guards , and the Doctor concludes that the timeship is small , with perhaps half a dozen Daleks . He realises , as well , that Leela must have been interrogated , and will be inside the timeship . Coulson has little choice but to go with him ; but first , the Doctor borrows Coulson ’ s “ little TV ” ( a smartphone or datapad , presumably ) . Inside the timeship , the Daleks release Leela from her bonds . She insults them , and insists that the Doctor will defeat them ; but they decide to have her robotized . They have the Robomen place her in the robotizing unit for conversion . She is at first able to resist the control wave , but the Robomen increase the power accordingly . On the moon , the test ends , and Lydia and Kevin question Stephens about the high energy levels ; at that level , and worldwide , they would be a hundred times the amount of energy needed by humanity . However , Stephens has set the controls to maximum , and started the countdown . In the National Gallery , the Doctor encounters some Robomen , and uses the television device to overload the microwave control signal , disabling them . He and Coulson disguise themselves in the Robomen uniforms and make their way to the chamber where Leela is imprisoned , encountering more Robomen along the way ; it seems Leela is causing trouble with the robotizing process . The Doctor again uses the TV device to disrupt the control wave , and frees Leela from the machine , introducing her to Jack . He discovers a Janis thorn in the back of a dead Roboman ; the Doctor scolds Leela for using them , but not harshly , as the Robomen are mostly dead already . The Doctor searches for the energy source , and finds it is close by , about a hundred yards away . However , a Dalek enters the room and catches them ; the Doctor , Leela , and Jack get the Dalek into the robotizing unit and activate the machine at full power . The Dalek becomes briefly compliant under the effect of the machine , and the Doctor interrogates it . It reveals the Daleks are there to use the solar energy — focused from the moon — to destroy humanity . It reveals a teleport ( transmat unit ) nearby , connecting to the moonbase . The machine overloads and explodes , disabling the Dalek . The Doctor , Leela , and Coulson hide from the Daleks in Stephens ’ office ; the Doctor reveals that the transmat unit is in the office — specifically , built into Stephens ’ chair . As the Daleks break in , the Doctor activates the unit , teleporting the three of them away . They arrive on the moonbase , in Stephens ’ bed ; Stephens is also there , but unconscious . The Doctor disables the transmat , preventing the Daleks from following . However , before he can do anything else , Kevin and Lydia discover their presence and take them into custody . Lydia recognises Jack , giving the Doctor an opportunity to explain ; he accurately describes the current situation . On Earth , the Daleks take their ship and set course for the moon to exterminate the Doctor . En route , they send a signal to reactivate Stephens . As Stephens awakens , the Doctor reveals that Stephens is a high - functioning Roboman . Stephens recognises the Doctor , lending credence to the Doctor ’ s explanation ; this makes Kevin hesitate at obeying Stephens ’ order to kill the Doctor . Jack tries to get through to Stephens , but is unsuccessful , and the man runs from the room to obey his Dalek orders . As the others follow , Kevin gets a message from the control centre of the base , stating that the Daleks have arrived — and moments later , the control centre crew are exterminated . Shaken , Kevin leads the Doctor and the others to the energy transfer controls , where Stephens is accelerating the process . Kevin and Lydia evacuate the rest of the crew while the Doctor deals with Stephens . Leela convinces the Doctor to let Jack talk to Stephens again , as she knows it is possible to resist the Robomen control wave . Jack distracts Stephens while the Doctor examines the layout of the transfer system . Jack successfully breaks through to Stephens ’ buried emotions , but he is unable as yet to stop him from his work . Meanwhile the Daleks are advancing on the transfer control room . The Doctor realises that the system , when fully active , will put a force field around the Earth ; but why ? Stephens manages to reveal the Dalek plan : the overpowered energy source will counteract gravity , expelling the moon from orbit , and thus causing massive meteorological changes that will exterminate humanity . The Daleks arrive at that moment , and confirm this ; they state that the controls are locked , but the Doctor insists on trying to stop the plan anyway . Meanwhile , Leela can hear the sound of the Dalek timeship nearby . The Daleks can ’ t fire on the Doctor , for fear of destroying the controls . Stephens tells the Doctor to access the power grid of the directional controls , and the Daleks immediately exterminate them . They threaten to kill Leela to get the Doctor to stop , and he is forced to do so . The countdown reaches zero , and the transfer begins . Exultant , the Daleks explain that they came back in time to ensure the extinction of humanity before their many future battles with the Daleks . The Doctor orders his friends to cover their ears , and he activates the same sonic wave he used on the Robomen , disrupting the Daleks ’ concentration and impairing their vision . The Daleks retreat , still confident they have won . The Doctor reveals that yes , the beam will still fire . As the Daleks prepare to leave , they discover that the beam has been redirected at the timeship ’ s power source . The ship explodes , destroying the Daleks and damaging the base . The Doctor tells the others what he has done , and credits Stephens with the final clue that allowed him to redirect the beam . Jack mourns Stephens ’ death , and the Doctor admits that he does not know if Stephens could have survived had he not been exterminated . He reflects that there is a lesson to be learned from Stephens ’ desire for a shortcut to the future . He sets to repairing the transmat for return to Earth .
