Plot
As K9 and Starkey make their way by the River Thames to Fish Starkey explains Fishing to K9 who considers it Inefficent as he could easily take out all the fish with his Photon Beam. Two CCPCs then halt them, asking them what they are doing. K9 then explains fishing to them, they like K9 don't understand it and go. As Starkey and K9 arrive they find several fish dead on the floor. As Starkey prepares to touch it, K9 warns him not to as he has detected an unknown alien substance. Starkey then manages to swipe one of the dead fish with his net which accidently hits K9, causing some of his body to sparkle red. At the Gryffen House Jorjie is singing to some music and she elbows Darius who is carrying a pile of books. Gryffen then spots him, Darius tells him the books could be interesting to look at but he obviously isn't telling the truth. Gryffen asks him if he was going to sell the books, Darius denies it but Gryffen tells him to pick them up and take them back to the Library.

Jorjie then starts singing again, Gryffen has to raise his voice to get her attention and tells her to quieten down. As Darius goes to the Library to return the books, he turns round to see two aliens who appear and then dissappear. At Gryffen's House Starkey takes readings of the toxin on the dead fish. Gryffen is shocked at the results of the unusual chemical composition. Gryffen asks Starkey to search through the database as the toxin is definitly extraterestrial. Darius comes in and tells them of his encounter with the aliens, and questions the weird sparkling on K9. Gryffen takes a look at it. Starkey finds a match ,Chenium a corrosive byproduct from the manufacture of Qualon 37, used in the manufacture of inter-dimensional starships. K9 then estimates if it builds up in the food chain, 85% of life in the Thames Valley will die.

In June's office Drake is talking to a CCPC through a Department computer, who tells him the prisoners are withholding information they need, Drake orders them to be more persuasive. June arrives and asks why he's here and speaks to him about his special security unit. She tells him how she sent her squad to investigate possible alien activity but were turned back by Drake's unit. She warns that alien threats are above all other Department operations, and if her squad is blocked again she will inform LOMAXX. Drake is then contacted by the CCPC who tells him the aliens won't stop talking, Drake then tells June he won't "upset" her squad again. He then tells her he has business to attend to, she then leaves.

K9 and the team go to point where the toxin is entering the river, Starkey then spots the same aliens as the ones imprisoned and who Darius saw, they knock Starkey to the ground. When he complains about his eyes they take him to Gryffen's house where Gryffen takes a look and determines it to be a strong case of vertigo and that his eyesight will return to normal soon. Starkey tells Jorjie he is fine but Gryffen gets him a bucket ("Just in Case") when he starts to feel sick. When Darius asks who the aliens that appeared were, K9 looks them up on his file. He recognises them as the Medes, a species that can project themselves as Avatars when they cannot psyhically be in a certain area. They decide to go to the source of the pollution, although Darius has doubts. K9 goes through the drains as Darius and Jorjie follow him through the streets, Gryffen and Starkey monitor them.

K9 feels uncomfortable and his transmission starts to break up. In Drake's office June finds the missing schematics for a Fallen Angel on his computer. When Drake arrive she asks him his interest in the ship, he replies the entire Department wants to know where its located. When she asks him about the featured detail on the top, he replies he has no idea and tells her to leave as he has business to attend to. Before she does so she warns him he best not be revealed to be in possession of the ship. Drake then contacts the CCPC who tells him the aliens aren't cooperating, Drake then authorises the use of torture. June then goes to Gryffen's house and contacts him, he then goes downstairs to meet her. She shows him a blueprint of the Mede starship and the molecular refractor on the top, she tells him Drake is exploiting it. She goes on to tell him that its Drake and not the Department who is using this, Gryffen says why as Drake is head of security. She tells him that the molecular refractor gives the ship the ability to dematerialise and with this he could use it to spy anywhere and not be seen by anyone, even LOMAXX.

As K9 searches he tells Darius and Jorjie the fumes are interfering with his inertial compass, Jorjie then spots a factory. They both make their way to there, Jorjie contacts Starkey who tells her Gryffen is talking to her mother downstairs. Jorjie wonders wether she should press on, Starkey tells her to do so. Jorjie then moves on, as Darius slowly follows. Gryffen and June analyse a image of the Mede Avatar, the Avatar is nowhere to be seen in infa-red vision. Gryffen wonders why the Medes project themselves when the can dissapear and reappear, June suggests its due to the abscence of the refractor. When Starkey insists Gryffen tells June the situation, Gryffen informs her that Darius, Jorjie and K9 are looking for the source of the pollution in North West 12. June then contacts her and warns her to get out but she and Darius are apprehended by CCPCs.

June decides to go there, Starkey follows but Gryffen warns he must not go because he hasn't fully recovered. As Gryffen tries to stop Starkey, Starkey leaves the house and Gryffens Agoraphobia kicks in, causing him to shut the door. Darius and Jorjie are tied up, Darius tries to break free by gnawing at Jorjie's rope. While searching, K9 calls out if anyone is responding. Gryffen responds but can't understand him, K9 then sees the Medes as Avatars. They tell him to come with them, he responds in their language, they take him to the source of the pollution. He enters the factory and spots the workers casting the Chenium, and finds Darius and Jorjie and blasts their rope. They run but are met by a CCPC, they turn the other way while K9 blasts it. Darius and Jorjie get the gates and are captured. June then interrupts with a command override, the CCPCs then take the workers away.

Starkey meets up with K9, who asks him to help him deliver the molecular refractor to the Medes. K9 tells June that Drake had the Medes locked up, K9,Starkey and June then visit the Medes in their cell. She gives them the refractor and apologises the what Drake did to them and informs them they are free to go. The Medes then reply that they need to do one more thing before they leave, and that thing is to clean up the pollution. They also repair the damage to K9 and leave in their ship. After noting the "Awesome" day they had, Starkey asks K9 if he wants to go fishing. K9 cheerfully refuses and chuckles along with Jorjie.

Production errors

 * While other episodes do try to use matte paintings to establish some London landmarks, this episode's exteriors aren't really treated in any way. It is blatantly obvious, especially as the characters are at the river side, that they're not anywhere close to the Thames. Tropical trees can easily be seen on the other side of the river, and the wide shots don't reveal any architecture that even slightly resembles London. Much of the action also takes place under a bridge that runs parallel to the river — something that doesn't exist in London. This story is set in 2050, which is 40 years in the future. Its possible that London has changed a lot in those 40 years.
 * When K9 cheerfully refuses Starkey's offer to go fishing at the end of the episode, the lights on his face that go on when he speaks don't flash.

Continuity

 * This episode establishes that the reason this K9 unit's language is laced with so many English colloquialisms is that the 5000 Earth movies on his memdrive have influenced his mode of expression.
 * This episode definitively establishes that K9 has some sort of on-board linguistic database, as he is able to talk to the Medes. This point was never particularly clear in his (or his successors') usage in Doctor Who, since he would have ostensibly had access to TARDIS translation circuit. Moreover, he's never been shown to use other languages in The Sarah Jane Adventures.
