-> ''You're sorry for me aren't you? I'm perfectly all right, you know. I don't care if nobody ever comes. I'm fine. I'm perfectly all right!''
-->-- '''Vicki''', who is not all right

The Doctor, with Ian and Barbara still in tow, arrives on the planet Dido some time in the 25th century. The planet is home to a crashed Earth spaceship, with two survivors on board: the paralysed Bennett and the young orphan Vicki. Both are fearful of a native monster called Koquillion, who has apparently killed the other members of the expedition.

Ian and Barbara soon run into Koquillion, and the Doctor explains that despite Koquillion's spiky exterior, the natives of the planet are extremely friendly. This one isn't, though, but before the Doctor can investigate, he and Ian are unceremoniously placed in a DeathTrap. With a rabid beast lurking below.

While they escape, Barbara is hidden by Vicki, and tries to come up with a plan. Vicki keeps trying to reassure her new friend that a plan won't be necessary, since the rescue crew is due to arrive in a few days. But Barbara doesn't want to wait that long and goes off to find her friends, shooting the rabid beast in the process... only to discover that it was Vicki's tame pet, the only close friend the girl had left in her life.

The Doctor mediates between a very distraught Vicki and his humans, and decides to have a good long talk with Bennett. He finds out that Koquilion is in fact Bennett in disguise (he's not really paralysed, of course), and he has killed the other crew members in order to conceal a murder he committed earlier. He's also been killing the native Didonians, and believes he has in fact wiped them out -- but a confrontation with two Didonians causes him to fall to his death from a high cliff. The Didonians have had enough of outsiders for a very long time, so they make sure the rescue team never arrives. It doesn't need to, since the Doctor misses Susan so much that he agrees on taking Vicki along.

!!Tropes

* AdoptTheDog: The Doctor was already NeutralNoLonger during "The Sensorites", but this episode sees him ''inviting'' someone into his TARDIS.
* ArtisticLicenseGunSafety: Vicki checks the load on her flare pistol, and readies it while pointing it directly at Barbara's face.
* BeardOfEvil: Bennett.
* DeathByIrony: Bennett tries to kill Barbara by pushing her off a high cliff while disguised as a Didonian in a ceremonial garb. When the real Didonians came out to confront Bennett, they indirectly cause him to fall off a high cliff and die.
* DirtyCoward: Bennett, he's reluctant enough to get into a fight with an old man when he thinks he has the advantage, but when confronted by two young, fit and very very angry Didonian survivors he just backs away in terror.
* DisneyVillainDeath: Bennett is so shocked by the appearance of the people he thought he'd killed that he backs away over a cliff edge.
* DontYouDarePityMe: See the page quote.
* ExpositionVictim: The Doctor foolishly does this with Bennett and comes very close to getting killed. He defends himself well, though.
* GettingCrapPastTheRadar: Some of Ian's mocking mispronunciations of "Koquilion" verge on this.
* HandsOffMyFluffy: Barbara shoots Vicki's pet monster because she thinks it's attacking her.
* HeroicBSOD: At the start of the serial, the Doctor habitually asks Susan to help him with the TARDIS, only then realising that his beloved grand-daughter really has left. The akward few seconds of the Doctor helplessly standing in silence [[TearJerker really sell it]].
* HumansAreTheRealMonsters: Bennett is the true main antagonist of the serial. However he is clearly not any sort of [[TheSociopath standard]]
* ImStandingRightHere: The Doctor comes out of the TARDIS to tell Ian and Barbara that he ''can'' hear what they're saying about him right outside.
* LiteralCliffhanger: The story ends with the TARDIS materializing at the edge of a cliff, only to tumble over.
* MetaTwist: By this point fans had gotten used to the shows not so realistic costumes for aliens, so the reveal that Koquilion is really just costume and the Didonians actually look like normal humans, is actually a pretty good surprise.
* NeverOneMurder: Bennett murdered a single crewman, to cover up his crime he killed the rest of the crew and then committed genocide against the peaceful Didonians's. He likewise tries to kill The Doctor, Ian and Barbara when they arrive.
* ObfuscatingDisability: Bennett.
* ProperlyParanoid: Vicki only not really.
* RecycledSoundtrack: To save money, the score is reused from "[[Recap/DoctorWhoS1E2TheDaleks The Daleks]]"., which Christopher Barry had partially directed. He selected pieces from episodes one and four through seven of that serial.
* ScoobyDooHoax: The spiky alien look is just ceremonial garb.
* ShoutOut: To avoid revealing that Koquilion was another character in disguise, the first episode credits showed him as being played by "Sydney Wilson". This was a joint Shout Out to the two BBC executives responsible for ''Series/DoctorWho'', Donald Wilson, the Head of Series and Serials, and Sydney Newman, the Head of Drama.
* SpaceClothes
* TheSociopath: Bennett is one of the most disturbed examples in the shows whole history, content to commit mass murder to the scale of outright genocide to save himself. What's most scary is just how casual he is about what he's done.
* {{Zeerust}}: Apparently tape recorders will still be in use in the 25th century.
