At night , in Coal Hill Academy , a student is chased down a corridor by an unseen creature , when he is suddenly pulled aside by a woman with blonde hair . While they are hiding , a shadow slides in underneath the door , and from the shadow emerges a tall molten - stone like monster . It cuts to a shot outside the room ; a gunshot is heard and the young man screams . Elsewhere , a crack begins to open out of thin air , through which can be seen a very volcanic looking landscape and suddenly , a shadow flies out through the crack . . . The following day , students around the school are talking about the student ' s disappearance , with one boy saying that " Everybody knows students at this school disappear - they all just pretend it isn ' t happening " . In the entrance hall , April MacLean tries to convince Tanya Adeola to help her decorate for the Autumn Prom , but she declines on account of her strict mum . April ponders over asking new boy , Charlie , as her date . The new physics teacher , Miss Quill , argues with the head teacher , Mr Armitage over her new position but ultimately concedes . While everybody heads to class , Charlie notices a strange shadow on the ground . Students mumble about mundane topics throughout the class , while Miss Quill subsequently chastises them equally over some of their personality traits . After class , Charlie tells April that he plans on taking Matteusz as his prom date , slightly disappointing her . At a football match , Ram Singh is about to score a goal when he notices a shadow move across the ground and take the form of another boy ' s shadow . As a result , he misses the goal . Tanya is walking home , contemplating whether to help April decorate for the prom ; unbeknownst to her , a lone shadow is quickly following her . As she turns , she sees a shadow growing across the wall and she runs . The shadow , now grown to the size of a building , chases her into a shop . She dismisses the event as her being under too much pressure . Charlie makes his way back home , where Quill is waiting for him . Tanya attempts to convince her mum to allow her to go to the school prom , but she immediately dismisses the thought . Miss Quill sits , eating a chocolate bar , while Charlie asks her if she had anything to do with the student ' s disappearance . It ' s revealed that she handed Kevin Williams a gun and told him to shoot the creature from the shadow , and it disintegrated him . She goes on to tell Charlie that while she is currently bound to " slavery " , she will protect him but he should not question her . Later that night , April is decorating for the prom alone , when the shadow seeps across the hall floor without her immediate notice . Then her own shadow moves , but she dismisses this too . Elsewhere , Tanya is talking to Ram on her laptop , when he notices a tall , darker shadow move across her room . She turns to look . April finishes her banner , when the shadow of a hand slides over her hand and pins it to the floor . In Tanya ' s room , the same creature comes out of the shadow and attacks her ; she manages to fend it off with a lamp while Ram calls for help . The shadowy hand releases April , who turns to see Miss Quill standing above her ; she says they are " in terrible danger " . The two run through the school corridors when the monster appears , and Quill tries to get April to use the displacement gun , knowing it will kill her too . At the last moment , Charlie runs in and saves April from the beam facing in her direction , while the one facing the monster hits it and it falls , and the one in Tanya ' s room disappears . The creature rises and April cries in pain . Quill scans her and the creature , revealed to be Corakinus , the king of creatures called Shadow Kin , with the gun , and finds that it and April now share a heart , given that the Shadow Kin ' s original heart had been displaced in time and space . Charlie refuses to kill the Shadow Kin , as it would also mean killing April . The Shadow Kin retreats through a crack in thin air and it closes shut behind him . Quill makes a call to someone , telling them that they ' ve got a problem . Tanya and Ram have both filled their rooms with lights in a bid to keep the Shadow Kin from coming back . Back at the school , Quill is contempt in going after the Shadow Kin to kill it , but Charlie refuses . He goes on to explain to April that he and Quill are both from another planet , and that he was prince of his species , the Rhodian s . Miss Quill was a member of the Quill , who were seen as terrorists ( or " Freedom Fighters " as Quill puts it ) on the planet , and when the war between them was over , Quill was bound to service to Charlie through the use of an alien parasite called an arn , explaining why she cannot use weapons . Charlie goes on to explain that while the Rhodians and Quill were fighting among themselves , the Shadow Kin came to the planet and slaughtered all the Rhodians , including Charlie ' s mother . Charlie and Quill fled to the city ' s vault , where Quill took the gun and Charlie took a peculiar looking box , right before the TARDIS materialised in the room . They were rescued by " a figure of legend , out of space and time itself " , who dropped them on Earth , and told them to fit in and tell people they were from Sheffield . April again cries in agony as her heart is split between her on Earth and Corakinus on the other side of the universe . She hears its thoughts and tells Charlie that it wants something he has , and that it ' s coming for it tomorrow night . At their homes , Charlie glances at the cabinet he took from his planet ' s vault , while April lays staring into the starry sky , hand against her heart . In the morning , April warns Tanya to be careful of her shadow at the prom , a message she later passes to Ram along with everything else April learned . April , Ram and Charlie prepare for the prom , while Tanya tells her mum that going helps her with a school assignment , so she would be allowed to go . Charlie , April and Matteusz make it to the prom , along with Ram and his girlfriend Rachel . During the party , April collapses and enters the Shadow Kin ' s mind again and learns that it ' s coming through the crack . Ram and Rachel step outside of the party , where the Shadow King murders Rachel in front of Ram . He demands to know where " the Prince " is , speaking through April at the same time . Ram fights the Shadow Kin while more start advancing for the other end of the corridor . Charlie takes the gun and attempts the hold them off . April and Tanya attempt to get everybody out while the teachers are outside with students vomiting or crying . April announces that everyone is in danger , but nobody acknowledges her . Suddenly , Charlie and Quill burst through the door , Charlie still shooting the approaching Shadow Kin outside , and everybody turns to face them . The Shadow Kin burst through the door and everybody runs . Outside , Ram continues to fight the Shadow Kin ' s king , enraged at him for killing Rachel , when it gets the upper hand and dismembers the lower half of his leg . While he screams , the Shadow Kin makes for the hall . Everybody flees the school in panic , while Charlie continues to hold off the Shadow Kin . The Shadow King comes into the room and destroys Charlie ' s gun . Just as it ' s about to kill all in the room , the Twelfth Doctor , the man who saved Charlie and Quill , strides into the room . He explains that he is here because Quill called him for help , and demands to know why the Shadow Kin are on Earth trying to kill Charlie and Quill , acknowledging that what they are doing isn ' t their regular M . O . The Shadow Kin demands the Cabinet of Souls , the item in Charlie ' s possession , which supposedly contains the soul of every dead Rhodian as a repository for a future paradise , or , as the Shadow Kin require it , a weapon . The Doctor does not wish for Charlie to use the cabinet to destroy the Shadow Kin as a method of avenging his people , describing it as " avenging genocide with genocide " . Charlie then reveals that the cabinet is empty and that the legends built up about it were merely a myth . Corakinus threatens to conquer the Earth with his legion , when April suddenly stands up to him , holding a broken chair leg to her heart , saying that she will kill herself to stop the Shadow Kin . Charlie also offers himself to Corakinus so that he will spare humanity and April . Tanya attempts to disperse the Shadow Kin by turning on the hall lights , and when that doesn ' t work initially , the Doctor boosts the lights ' voltage up with his sonic screwdriver , and the Shadow Kin disappear . Charlie and the others chase after them to get April ' s heart back , when April is grabbed by Corakinus . He gives the Doctor an ultimatum : kill them both , or let them live . Ram suddenly appears and hits Corakinus with a chair , pushing him back through the crack . The Doctor then closes the crack with his sonic screwdriver . Ram then passes out from exhaustion and blood loss . The authorities are called to help with the damages . The gang and Miss Quill are gathered around the TARDIS . The Doctor emerges , wondering what to do with the group now . Charlie knows that the Doctor couldn ' t close the tear completely , to which the Doctor explains that with all the artron energy built up around the school during the years of his travelling , time itself has worn thin . He forewarns the students that that the school still acts as a beacon to all of space - time and that more will be coming . Miss Quill is thrown that the Doctor is not taking them with him , but he explains they would be no safer elsewhere . All of a sudden , the Doctor stops in his tracks and takes paces toward a large board , on which are the names " Pink R . D . " & " Oswald C . " ( referring to Danny Pink and former companion Clara Oswald ) . The Doctor is sure that the students will be able to handle whatever comes through the tears . Ram emerges from the TARDIS , with an alien prosthetic leg . The Doctor leaves Quill on Earth to work with the gang as penance for the death of Kevin Williams , and assigns them the task of protecting the planet from whatever comes through the tears , much to Quill ' s chagrin . He then leaves in the TARDIS . Ram and Tanya go home in grief and disbelief over what had happened that night . Charlie promises April that he will get her heart back , and she tells him that in the meantime , she will adjust , telling him of how her mum was paralysed in a car accident . Quill later asks Charlie how he isn ' t mad with grief over the death of his people like she is hers . He responds that there wouldn ' t be a point , being furious . She then asks that is the cabinet were full , whether he would let the Doctor ' s moral of " committing one genocide for another " stop him , as it wouldn ' t stop her . It ' s later revealed that the Cabinet of Souls is indeed full , and Charlie stares into the box at the millions of Rhodian souls . Story notes . Filming location .
