The Seventh Doctor and Ace go to the library on Kar-Charrat to return some (very) overdue books on "Juggling For Alpha Centaurians". The library contains every piece of information from every planet: a collection to rival the Gallifreyan Matrix. Because such knowledge could be dangerous in the wrong hands, the library is hidden from most species by some time tweaking. Its planet is wet, covered in jungle and perpetual rain, and the library itself is located at the top of a waterfall.

The library rarely gets visitors these days, which -- as Ace points out -- might just be because no one knows it exists, and those who do know can't be bothered to climb a waterfall and leap through an undetectable time barrier. The Doctor, meanwhile, checks out the library's new data storage system, which runs on water.

Ace gets bored and wanders back out to the rainy wilderness, where she meets [[GirlOfTheWeek Bev]], a treasure hunter whose entire team was wiped out by a mysterious shouty robot, which certainly won't be important later. Bev herself doesn't do much this serial, but she'll be back later.

They get rather rudely interrupted by a dormant Dalek invasion fleet. The Daleks had been waiting for a way to get into the library (for a rather long time, in fact), and Ace wandering off with the key device was just the opportunity they needed. They clone Ace (which doesn't fool the Doctor), get past the library defenses (which doesn't scare the Doctor) and hack into the water-based data (which... kills the Doctor). Fortunately, the local sapient lifeforms turn out to be the rain itself, and they rescue him from the brink of death by absorbing his mind into their collective consciousness. Unfortunately, the data storage system turns out to be made of the sapient rain and practically lobotomised the species, and the Doctor gets really, ''very'' angry at the library staff when he finds out.

One of the Daleks gets all knowledge of everything ever uploaded into its brain, and Creator/NicholasBriggs gives his hammiest performance yet when the Dalek goes stark raving mad and subsequently decides to use its power for good instead of evil. It's killed by the other Daleks, of course, and the Doctor saves the day.

[[AnachronicOrder From the Daleks' perspective]], the first part of the ''Dalek Empire'' story. It's also Creator/NicholasBriggs' first ever time officially voicing the Daleks in proper, licenced ''Doctor Who'', a job he holds to this day.

In September of 2023 [=YouTuber=] and Whovian Josh Snares released an [[https://youtu.be/iXAScj2O78w?si=SqkUvaVSITfN9R1s animated video]] to be synced with the original audio that's worth checking out.

!!Tropes:
* AndIMustScream: Most of the Phantoms of Kar-Charrat are imprisoned in the Wetworks Facility; the liquid that embodies their sentience is used to store library text. Several manage to retain self-awareness, but many minds have succumbed entirely to the data.
* BodyHorror: A very, ''very'' rare heroic example, as this is the Kar-Charratans' only way to fight back against the Daleks.
* BreakoutCharacter: The first appearance of Bev, who will reappear in "Dust Breeding" and is ''all over'' the Franchise/BerniceSummerfield stories.
* CallBack:
** The Daleks make use of their rarely-seen robot duplicates (as in "The Chase").
** The Test Dalek's acquisition of cosmic knowledge, and thereby [[HeelFaceTurn benevolent wisdom]], somewhat recalls [[Recap/DoctorWhoS4E9TheEviloftheDaleks Alpha, Omega and Beta's infection with the Human Factor]].
* ElementalEmbodiment: The Phantoms of Kar-Charrat have bodies of water.
* EvilMeScaresMe: Ace doesn't like her Dalek clone one bit. Neither does the Doctor.
--->'''Doctor''': She lacks a certain charm.
* LeaveNoSurvivors: As per standard Dalek procedure.
-->'''Elgin:''' Where are the rest of the staff?
-->'''Dalek:''' [[foldercontrol]]

[[folder: All unnecessary human life-forms have been exterminated. ]]

* MoralEventHorizon: InUniverse: The Doctor's disgusted repudiation of Elgin on learning of his genocide of the Kar-Charratans.
* MySkullRunnethOver
* MythologyGag: Bev was named on the basis that a Creator/TerryNation-pastiche story ''had'' to have a character with a one-syllable first name and the surname Tarrant. (cf. Jill Tarrant in "Death to the Daleks", Cal Tarrant in the ''Dalek Annual'', Dev, Del and Dieter Tarrant in ''Series/BlakesSeven'', etc).
* NearDeathClairvoyance: The Daleks' attempt to download the data through the Doctor's brain briefly renders his body inoperative. Just in time, the Kar-Charratans absorb his mind into their midst, and shortly return it to his body.
* OOCIsSeriousBusiness: A Dalek ''doesn't want to exterminate''.
-->'''Test Dalek:''' [[/folder]]

[[folder: The life-forms are non-hostile. They do not require extermination ]]
.
* OutOfTimeOutOfMind: The ''very'' long-term Dalek plan to take over the Library.
* PossessingADeadBody: Bev's Dalek-slain partner Rappell is commandeered by several apologetic Phantoms, who sense the corpse's memories.
* PuppeteerParasite: The Kar-Charratans inhabit water, as in ''they're'' the water. They can do this to humanoids. Subverted in the fact they're friendly, and don't harbor any ill will towards the Doctor and co..
* RobotMe: The Dalek replicant of Ace.
* StarfishAliens: The Kar-Charratans are pretty "out there" even for ''Series/DoctorWho''.
* TokenGoodTeammate: The new lifeform the Daleks create based on the "knowledge of the universe".
* TheVoiceless: Prink never manages to get a word in edgewise until moments before his death.
* WhatMeasureIsANonHuman
