The Librarian takes a liking to Professor Gryffen and sets about tidying up the mansion . Plot . K9 flies to Department HQ and hides on its roof , curious about its new open day . He contacts Starkey in a queue to the entry with Darius , asking him if they have ever had a careers day . He replies it ' s a once in a lifetime opportunity . K9 doesn ' t like this . As he looks over people queuing , Starkey tells him to move back . In Department HQ , June is talking with Thorne . She is intrigued because the Department hasn ' t recruited like this before . Thorne tells her she keeps saying the Department needs to be open and transparent . The CCPC guard opens the door , letting the visitors in . Thorne arrives to greet the crowd and introduce himself . As they move on , Thorne tells everyone that the Department is a multinational security facility , offering career opportunities in the UK , the America s , the Pacific Union and other countries . Starkey and Darius stop and ask K9 where to go . He tells them to go back down the corridor the way they came in , the way to Thorne ' s office . As they make their way they spot a CCPC , the first they ' ve seen inside . K9 suggests they abort the mission . The CCPC moves on as Starkey and Darius get to Thorne ' s office . Darius stands guard at the door as Starkey investigates the office . Starkey finds an interesting picture on Thorne ' s desk . Despite K9 ' s warnings , Starkey moves closer and is sucked into it . A shocked Darius grabs Starkey ' s communicator . K9 tells Darius to take the picture and bring it back to Gryffen and by all means don ' t look at it . Darius and K9 arrive at the Gryffen House , and tell Gryffen that Starkey has been sucked into the picture , which K9 identifies as a Library card from Ukko . Gryffen wants to take a look at it but Darius warns him not to . K9 brings him up to date : Starkey used the careers day to get in Department HQ ; Darius and Starkey arrived at Thorne ' s office and discovered the Library card , and when Starkey looked at it he was sucked in . K9 tells Gryffen he thinks it ' s a set - up by Thorne . When Gryffen asks K9 what the next step is , he tells him to get a mirror . At Department HQ , Thorne enters his office and discovers the Library card missing . He looks at CCTV footage and finds Starkey and Darius . When a CCPC arrives , Thorne demands to know how they escaped . The CCPC tells him their orders were to allow them to find their way to his office . Using a mirror , Gryffen , Darius and K9 look at the Library card to find Starkey trapped on a barren planet , calling out for them . K9 tells Gryffen and Darius the Ukkan s are an all - female race of Librarians who mastered — or " mistressed " — the art of archiving . They can reduce a whole world to an infinitely compressed hologram , which they file in their archives as a library card . They do it because nobody else will ; they preserve endangered planets in holographic form . K9 compares it to squashing the data when you zip a file on a computer . This particular card is of the barren planet Urlic . K9 tells Darius they would have to speak to a Librarian to get Starkey out . Gryffen asks him how . K9 doesn ' t know . At Department HQ , June asks Thorne about the Ukkan Library card . He tells her he ' s exploring its properties for use by the Department . June tells him it ' s extremely dangerous and spots the base of the card on Thorne ' s desk . Back at the house , K9 confirms Darius ' observation that the light on the card is blinking faster . Darius answers the door and sees an alien on the doorstep . K9 says she is the Ukkan librarian they ' re looking for . She introduces herself as Yssaringintinka . She goes to take a look at the card , causing Darius and Gryffen to avert their eyes . She assures them she has become immune to the effect of the card over millennia . Gryffen tells her Starkey is trapped on Urlic . She is more concerned about Urlic than Starkey , as his presence threatens the planet with contamination if he leaves anything behind . Gryffen asks if she can get him out . She asks him where the plinth is . He tells her that the card is all that they have . She says she can extract Starkey with a retriever , but only if the card is on the plinth . K9 tells her it ' s at Department HQ . She tells them to go get it , but Gryffen warns her the Department doesn ' t like people dropping in . The Librarian gives everyone purple glasses to allow them to look at the card without being sucked in and so that they can talk to Starkey . They contact Starkey , and he says that he is thirsty because it ' s hot on the planet . They warn him to not leave anything behind . Yssaringintinka states that the card ' s fail - safe will close the portal in two hours . June goes to Thorne ' s office with a warning that Lomax wants to know why Thorne has been interfering with alien technology . As prison numbers are rising , he wants to use Ukkan technology to dump them on other planets . June warns him that LOMAXX wants the card back in twelve hours or Thorne will be forced to resign . Back at the house , Jorjie has arrived . K9 tells the team they have to do a deal with Thorne . They will offer him the card if he gives them the plinth to get Starkey out . Gryffen refuses , saying he hates liars like Thorne . He ' s a scientist and science is the pursuit of truth . K9 tells him that to a machine like himself , truth is just software . Yssaringintinka asks why he is careful with truth when his house is so messy ? " Tidiness comes before truth " . Gryffen is contacted by Thorne , who tells him he has something of his , he wants it back and if he goes to take it by force , people will get hurt . K9 interrupts . Thorne has stumbled across technology he wants to exploit but doesn ' t know how , so he set a trap . He can do nothing with the technology unless he has more information . He tells him about the Ukkan goggles and offers him the Librarian as a consultant . As K9 , Jorjie and Darius go through the tunnels , Jorjie is angry because Darius didn ' t tell her earlier about Starkey ' s plan to infiltrate Department HQ . Darius confirms he didn ' t want her to join in . Jorjie wants a look at the card to make sure he ' s all right . K9 tells her she can ' t . Yssaringintinka has the goggles disabled . Later , they meet with Thorne . Jorjie gives Thorne a pair of protective goggles . The reason Yssaringintinka disabled the goggles is revealed as Darius opens the box containing the card , double - crossing Thorne and sucking him into the card . Thorne has double - crossed them as well . His box contains a brick rather than the plinth . At the house , Gryffen sees Yssaringintinka making his cabinet neater . He tries to make it messy as she puts it back . On Urlic , Thorne is trapped with Starkey . Thorne tells him his plan to turn the planet into a prison colony and the first inmate will be Starkey . Starkey tells Thorne he ' s the second . Thorne is contacted by June . He demands she gets him out of there . June replies that Thorne is not in any place to make demands . June goes to Thorne ' s office in Department HQ and grabs the plinth . On Urlic , as Starkey drinks from his water bottle , Thorne tells him he ' s thirsty as well . Starkey doesn ' t care . Thorne tells him he should be grateful . If it weren ' t for him and the Department he ' d have nothing to rebel against . Starkey remarks that Thorne ' s shirt is " skanky " and he looks like he ' s " selling funeral insurance " . June arrives at the house and gives Yssaringintinka the plinth , with only three minutes until the link is closed . She tells K9 the position Starkey and Thorne are standing is crucial for the extraction . As Starkey and Thorne fight over the water , Yssaringintinka tells them where to stand and the others tell them to stop fighting . Thorne is persistent but Gryffen warns him to do what Yssaringintinka says . She says that the extractor doesn ' t work well with two entities , so they must put their arms around each other . Starkey grabs Thorne and they return to the house . When Thorne threatens to have everyone arrested , Yssaringintinka threatens to erase him if he harms anyone . He deserves erasure for his overdue Library card alone . She tells them that humans don ' t deserve to live on Earth as they have made such a mess of it . Starkey thanks her for retrieving him . She tells him it was her pleasure although the same can ' t be said for Thorne . She asks Gryffen to show her out . On the doorstep she asks him to come back to Ukko with her as they are short of men . He is tempted but passes . He thanks her and she teleports home . At night , as Starkey and K9 go to bed , Starkey asks if he missed him . K9 tells him that as a cybernetic robot he does not experience emotion , much . Starkey asks K9 to turn his night light off . As K9 falls asleep Starkey tells him he missed him . References . " to be added " Story notes . Ratings . " to be added " Myths . " to be added " Filming locations .
