But will their dreams turn to dust at a service station somewhere on the M62 , besieged by a pack of alien monsters ? Plot . In Bramlington , 1974 , Arnold Korns and siblings Trisha and Tommy Tomorrow are in a car while listening to rock music . Arnold then pulls them into a cafe to have a quick drink and from the cold weather outside . Somewhere outside of the cafe , a man is drinking and is intoxicated . Something approaches him , but he dismisses it as someone else . The creature then attacks the man , who lets out a scream . In the TARDIS , Lucie feels like she ' s about to throw up after a bumpy ride . The Doctor then suggests that they go somewhere to eat . The TARDIS materialises somewhere in Bramlington , 1974 , instead of the intended destination , 2006 , to return Lucie to her time zone . However , the TARDIS wouldn ' t allow them to travel there for some reason . As the Doctor tries to inform Lucie about the popular music in the ' 70s , they stumble across a dead body , which has been torn apart by an unknown assailant . In the cafe , a young woman named Pat is talking about Bendy Roger , who just walked out of the cafe , to the waiter , Flo . Pat expresses sadness that her band is no more now that the members have left . Suddenly , the power goes out much to everyone ' s dismay . Pat has no way of transport as she only walked there and Flo offers to drive her . Pat then notices Arnold in the cafe along with Trisha and Tommy and Arnold is actually her manager , who had hated her band . The Doctor and Lucie make their way into the cafe and they try to inform Flo and Pat about what they have found , but they have left the cafe as Flo ' s shift has just ended . The phones are mysteriously kaput and Arnold asks them what ' s going on . The Doctor informs him that they have found the body of a Glam rocker . Outside , Flo and Pat are walking towards Flo ' s car but they hear something following them . They panic and Flo accidentally drops the keys to her car . They give up and retreat back to the cafe and make it safely inside . Back in the cafe , the Doctor informs Arnold and the Tomorrow siblings that they might be in danger and they ' ll need resources . Suddenly , Flo and Pat burst in and shout that something ' s outside and they have barricaded the back door . Flo tells them that there ' s a glass walkway to another cafe , where an entrance is open that needs to be blocked . The Doctor orders Lucie to take someone with her to search for any openings to block so the creature can ' t make it inside . Pat describes the creature to be bear - like with large fangs and she is curious as to why the Doctor just instantly believed her . The Doctor responds that he has seen much more bizarre things . In addition , a man who calls himself " Ron the Roadie " helps the others barricade the main entrance to the quite and lonely cafe . As they ' re barricaded , Arnold expresses despondency that he needs to get to London to see Trisha and Tommy perform as they will be performing on Top Of The Pops tomorrow . Suddenly , they hear the creature outside and they witness it destroy Arnold ' s car to shreds . As Lucie , Trisha and Tommy walk the glass walkway to block another entrance , Lucie asks if Trisha recognises Pat , because she reminds Lucie of someone she can ' t quite place her finger on . Trisha doesn ' t know and explains that ever since Tommy has been playing a stylophone , he ' s been acting weird i . e . telling people that the songs he writes come from space . Tommy then stops playing the stylophone and says " they ' ll be here very soon " . Tommy says that " they " are talking to him as he continues to play his stylophone once more . He then says that the " Only Ones " are coming . Trisha tries to get him to stop this , but Lucie begins to hear ghostly noises . Trisha and Lucie hear the Only Ones say that they ' ll be with Tommy as long as he keeps the wavelength of the stylophone open for them . Tommy then says that this is what him and Trisha wanted when they both played their music . Trisha denies this as nonsense in unease and suggests getting the Doctor . Horrified , Arnold insists on going outside to his car after the creatures have disappeared . Pat insults Arnold to listen to her as she introduces herself as Patricia Ryder , a drummer from Methylated Spirits . She reminds him that he laughed at them at their performance in Crowley on Sea . The Doctor scoffs that humans fight over pop music in the face of danger and decides to go find Lucie . The Doctor then finds Lucie and the Tomorrow twins and asks if they barricaded the other entrance . Trisha explains that they didn ' t and that Tommy has been acting weird . Tommy tells the Doctor that " they " don ' t want the entrance to be blocked and the Doctor suggests that he should see Arnold ' s car for proof of their hostility . Ron becomes impatient and decides to make a run for it outside past his van to get help from the outside . Pat , Flo and Arnold argue that it ' s suicide . Ron ignores them and leaves the cafe . Arnold tells Pat and Flo that it was his decision just when the creatures are heard from outside followed by Ron ' s screams , confirming that they have found and killed him . Arnold callously compares Ron to his car , to which Flo and Pat are angered by . The Doctor , Lucie and the twins return and are angered to learn that Arnold simply allowed Ron to go outside and get himself killed . Later on , Flo serves everyone some hot tea and food to keep themselves sheltered within the cafe . Lucie and the Doctor secretly talk to each other and both analyse how the creatures are starting to amass within this area as if they ' re circling around something . This leads them to believe that Tommy ' s stylophone has something to do with it . Somewhere else , Tommy tells Arnold and Trisha , who are arguing , that the Only Ones say that the Doctor is bad and shouldn ' t listen to him . Meanwhile , Lucie and Pat share another cup of tea and Lucie asks Pat if she has seen her before . Pat denies knowing her and that people just ignore her seeing how she is " Passed - over Pat " . Lucie then asks if her name is Patricia Ryder . Pat answers yes , confirming that Pat is revealed to be Lucie ' s " Auntie Pat " from the past . Pat doesn ' t recognise Lucie as she was not born yet , but Lucie tells Pat that she is time travelling with the Doctor and she is Pat ' s niece . Pat decides to accept this and asks more questions about the future . Lucie reluctantly and glumly tells her that in the future , she won ' t become a drummer and she ' ll just stay as her Auntie Pat . Arnold grows impatient about missing the Top of the Pops performance and decides to take Trisha by force . As Trisha fights back , Arnold becomes hostile and grabs a knife and yells that Trisha and Tommy go with him . The others notice this and the Doctor tries to talk Arnold out of doing this , but he stays firm . Arnold demands Flo ' s car keys and she hands them over to him . Arnold then gets Tommy to move the fridge away from the door and the three exit the cafe . Pat then urges the Doctor that he can ' t let them go as they are in dager from the creature . Arnold keeps insisting on leaving , just when the creature attacks and Trisha is killed as Arnold makes his way back inside safely , leaving Tommy outside . The Only Ones then tell Tommy that Trisha was only a human on Earth and doesn ' t matter . Angered , the Doctor berates Arnold for Trisha ' s death at the hands of his cowardice . Lucie then proceeds to go outside to fetch Tommy , who is sobbing at his sister ' s death . Tommy insists that the aliens have powers to bring her back , but Lucie tells him to come back , but he runs away . Inside , Arnold ' s leg is injured and the Doctor tells Pat to get Ibuprofen from Lucie ' s bag . Instead , Pat finds an MP3 player , which she doesn ' t know what it is because of the time period . Pat then asks if Lucie ' s claims that they ' re from the future are true , to which the Doctor confirms and glooms over the fact that they ' re not helping much . Arnold complains further about his injuries and Pat tells him to shut up or she ' ll " zap " him with the MP3 player . Hearing those words , the Doctor then gets an idea as he reveals that he now has Tommy ' s stylophone and he nabbed it from him during the scuttle of coming back indoors . The Doctor orders Pat to go after Lucie and Tommy while he needs Flo ' s help with the stylophone . The Doctor tests the stylophone ' s noises , but can ' t remember the notes . He asks Arnold to sing along so he can hit the correct notes . Outside , Tommy tells Lucie that the Only Ones promised him and Trisha that they ' ll take them across the universe . The reason why they ' re called the Only Ones is because they ' re literally the only ones who don ' t see themselves as cold - harded , cruel people like on Earth as they see it . Tommy tells Lucie that they ' re the only ones out there in the universe now . Lucie then tells Tommy that this is false because there are billions and billions of life forms out there . Pat then shows up and tells them that the Doctor requests them back immediately . Tommy realises that the stylophone is gone and begins to strangle Pat , demanding it back . The Doctor plays along with Arnold ' s singing and the stylophone begins to respond . The Only Ones ' voice says that no place is good and to " come with us Tommy " . Lucie rushes back into the cafe and informs the others that Tommy has gone delusional after his sister ' s death and is willing to kill Pat . The Only Ones demand to be let in and the Doctor decides that he may have increased their energy . The creatures burst into the cafe , startling everyone . Arnold decides to stay behind to fight them off in order for the others to escape . The others escape the cafe as they hear Arnold ' s screams and find Tommy and Pat . Tommy demands for the stylophone back , but the Doctor offers that he returns Pat for trade . Tommy gives up Pat and plays the stylophone once more . As he plays it , the Only Ones appear before them and announce that they have come to take them away . The Doctor calls their bluff and demands to know the real reason they have come . The Only Ones then reveal that they are aliens that have fed on humans as a source of polyunsaturates . They used Tommy as a way to lure fans with his music . Tommy asks about Trisha , who meant nothing to the Only Ones after all . Overwhelmed with emotions and betrayal , Tommy faints and the Only Ones close in on the group . Suddenly , Arnold reveals himself to still be alive . He explains that he escaped from the creatures and tosses Flo ' s funnel , which is what the Doctor needs to stop the Only Ones . As the creatures surround them , the Doctor reverses the output frequency and the sequences of notes , thus turning them into nothing but sound . Using the funnel and Lucie ' s MP3 player , the creature are frozen within the MP3 player on shuffle one . Lucie fancies the idea of having monsters on her MP3 player , but the Doctor urges her to never play that track . In the aftermath , Tommy comes to and is emotionally damaged , but Arnold promises to be there for him as he knows how to handle the " disillusioned youth " . Before leaving , Lucie bids her aunt farewell and Pat accepts the fact that Lucie is her niece from the future . The Doctor and Lucie exit the cafe and see that the storm has died down . On their way back to the TARDIS , the Doctor asks if it ' s a bad thing to consider exploring the universe if the opportunity comes to be . Lucie says that it ' s okay to and then asks who will have caused the mess if anyone asks any questions . The Doctor jokes that it was Hell ' s Angels , which he was a part of once . Back in the cafe , Pat regrets not asking Lucie about many things about the future , but Flo assures her that it ' s probably the best to look forward instead . A mysterious woman enters the cafe and asks if Lucie Miller was here . The woman refuses to give her name and explains that it ' s vital that she gets her . Pat and Flo say that they ' re off travelling somewhere and have no idea where she is . The mysterious woman is revealed to be the Headhunter .
