JustForFun/{{The one w|ith}}here the Doctor gets stuck with a coat rack.
----

Tegan wants to see something of humanity's future. So when the Doctor takes the TARDIS to Frontios, where sometime in the distant future the last remnants of humanity huddle together under semi-primitive conditions and occasionally get devoured by the ground or squashed by meteor showers, she insists on going out and checking up on them.

The Doctor, as usual choosing quickly to disregard Time Lord rules about not interfering, tries to help out. The locals, also in the usual way, treat the Doctor as a threat rather than a helper, but Turlough saves him by waving a hatstand in a threatening manner. Then it turns out the problem is giant insect aliens that used to attack Turlough's people too, and he has a prolonged fit of [[ChewingTheScenery scenery chewing]]. Eventually our heroes, together with the more reasonable Frontios-humans, fight the Tractators by [[BriarPatching outwitting]] their only articulate, thinking member, the Gravis. So that's all right. And they'll all get a nice break next, [[BlatantLies promise]].

!!Tropes:

* ApocalypseHow: Apparently the Earth ''collided with the sun'' somehow.
* AllThereInTheScript: Two of the colonists are called Kernighan and Ritchie (see ShoutOut below), but the scene containing the dialogue establishing this was cut.
* TheArk: Brought the humans to Frontios, then promptly crashed, leaving them without their advanced technology.
* BigBad: The Gravis.
* BigCreepyCrawlies: The Tractators.
* BoundAndGagged: Norna in Episode Four.
* BriarPatching: The resolution of the story - the Doctor persuades the Gravis to use his powers to reconstruct the fragmented TARDIS, by pretending that he deliberately broke it up to prevent the Tractators getting hold of it and that the last thing he wants is for the Gravis to reassemble it.
* ColonyDrop: The meteor showers engineered by the Tractators.
* CompanionCube: Rather puzzlingly, the hatstand that's been just standing in the background of the [=TARDIS=] gets a huge spotlight in this story. From the start, the Doctor suddenly acts irritated at its presence and asks Tegan and Turlough if they want to get rid of it. Later, when the [=TARDIS=] is seemingly destroyed, the hatstand is the only thing left from it and Turlough proceeds to use it as an ImprovisedWeapon against an angry mob. At the end, the Doctor repays the Frontiosians' kindness... by gifting the hatstand to them. All in all, by some regards the thing was given a more emotional sendoff than the ''Sonic Screwdriver''!
* CrapsackWorld: Frontios.
* DeadpanSnarker: Five, by this point, has become almost as prone to this as his squabbling companions. E.g. "Oh, marvellous. You're going to kill me. What a finely tuned response to the situation."
* DeathGlare: Tegan manages a serious one when the Doctor, having [[ItMakesSenseInContext passed her off as an android to save her from the Tractators]], throws in a gratuitous bit about having got her cheap because "the walk is wonky and the accent's wrong".
* FamilyUnfriendlyViolence: People are dragged screaming down into the ground, and we see a digging machine controlled by a [[WetwareCPU severed head]]. (The latter scene was actually toned down compared to the script, which had the entire machine made from dismembered human body parts.)
* GeneticMemory: With a large side of IncomingHam, punctuated by [[HeroicBSOD BSOD-ing]].
* GoodSamaritan: The Doctor is trying to obey the rules about non-intervention when he sees there are wounded.
* GravityMaster: The Tractators are powerful enough to displace the TARDIS' walls.
* GravitySucks: And the Tractators use it to swallow people through holes in the ground.
* HeroicBSOD: Turlough has a full-on PTSD breakdown upon seeing the Tractators, and spends a good deal of the rest of the story in some kind of state of shock, due to remembering what they did to his home planet.
* [[HiveQueen Hive King]]: The Gravis. Without him the other Tractators become harmless.
* HollywoodAcid: Turlough spills some acid on the metal floor of the colony ship, which creates a hole almost immediately.
* HumansThroughAlienEyes: Apparently we're quite pathetic compared to Trions, says Turlough. And Tractators, says the Gravis. Even the Doctor gets in on it.
* ImprovisedWeapon: A hatstand, which also, thanks to the Doctor's rambling "Not hat people, are you?" talk, counts as ChekhovsGun. It works, too.
* IWasNeverHere: And the Doctor is most insistent on it.
* LargeHam: Turlough in breakdown mode.
* MadeASlave: The captured humans.
* MistakenForSpies
* NiceJobFixingItVillain: Played literally. The Doctor gets the Gravis to restore the TARDIS, cutting off the Tractators from its influence and rendering it docile enough for the Doctor to dump him elsewhere.
* ObstructiveCodeOfConduct: Time Lord rules about non-interventions go out the window early, for a change.
* OneWordTitle
* PatrickStewartSpeech: Plantagenet delivers one in Episode 1, about how the humans' indomitable spirit will overcome the endless meteor bombardment.
* PluckyGirl: Norna.
* PurelyAestheticGlasses: This story being written by the guy who gave the Fifth Doctor his specs, out they come again.
* RefugeInAudacity: Attempting to protect the Doctor, Turlough takes up the TARDIS' hatstand. Due to a single, small discharge of residual energy from it, the paranoid leaders believe it to be a lethal weapon. He does nothing to dissuade them from the notion.
* RippedFromTheHeadlines: The desolate, Blitz-like setting was influenced by contemporary reports of fighting in Beirut during the 1982 Lebanon War.
* SchmuckBait: How the Doctor dupes the Gravis.
* ShoutOut: One in a deleted scene: two of the guards are called Kernighan and Ritchie, after the authors of ''[[https://en.wikipedia.org/wiki/The_C_Programming_Language The C Programming Language]]''.
* TheSoCalledCoward: "Of course not...I'm Turlough."
* ThinkNothingOfIt: Subverted. At the end, the colony thanks the Doctor for saving them, and he tells them, "Don't mention it." His companion Turlough clarifies, "He means it. Literally." i.e. the Doctor doesn't want the colonists to let the Time Lords find out about it.
* WhatHappenedToTheMouse: Kamelion, who's still supposedly inside the TARDIS at this point, doesn't seem to be a concern when the TARDIS is apparently destroyed.
* WhatMeasureIsANonHuman: "You can't possibly take their side!"
* YouCantFightFate: Turlough's professed motivation for going back.
