[[caption-width-right:344:"Oh, come on Governor! My [[ImpossiblyCoolClothes coat]] couldn't possibly be grounds for a hanging!" [[note]][[TakeThat Yes, yes it is.]][[/note]]]]

After the TARDIS breaks down in the middle of nowhere, the Doctor quickly decides that his life is over now and he'll be stuck in dead space for the rest of his regenerations. Peri convinces him to actually read the TARDIS manual for a change, which tells him that he could get the ship working again using some {{Unobtanium}} from the nearby CrapsackWorld of Varos. They land right in the middle of an execution. Timing is everything!

Being executed is Jondak the Rebel, who was trying to lead a fight against Varosian society. The government is something like mob rule crossed with BreadAndCircuses -- everyone's television is also a voting device. Since there's not a lot of food and entertainment left, society is hungry for any kind of distraction, and people's tastes have gotten ever more bloodthirsty. To distract the workers and discourage uprisings, public executions are carried out in a DeathCourse full of nastily fatal traps, the video footage of which is then sold to anyone willing to buy it. The current governor, who's constantly in danger of being executed through the TV voting system himself, sees no way out and has long since become accustomed to the way life on Varos works.

So the Doctor and Peri bogart with Jondar, picking up his wife, fellow rebel Areta, along the way, and make their way through the DeadlyGame. They are separated, trapped, recaptured, nearly killed, etc., until finally the governor convenes the Doctor and Jondar to the Gallows Room and begins to turn Peri into a bird unless the Doctor explains just why he's there.

The Governor and his guards all do a tentative HeelFaceTurn once they realise the Doctor may hold secrets of the outside world. However, they're also being extorted by a sort of fish-dwarf named Sil, a representative of the Galatron Mining Corporation. The Doctor is ''most'' annoyed that Peri is turning into a bird, even after he's revealed that the Varosians' zeiton ore is much more valuable than they'd been led to believe. Fortunately, the process is reversible. Now the group hobbles towards the exits, neatly avoiding the poisonous plants and the cannibals. In the end, the Governor is able to tell Sil where to stick his outrageous prices (as well as his invasion fleet) and announces a new golden age of prosperity, without any more entertaining DeathTrap executions. The people watching TV look positively crestfallen.

!!Tropes

* AgonyBeam: Used on Jondar.
* AmbiguousEnding: The ending seems positive, but the final scene adds a note of uncertainty, making it clear that the general population of Varos may be unable to accept living without their TorturePorn.
* AntiVillain: The Governor.
* ArsonMurderAndJaywalking: Peri complains that Six caused three electrical fires and a power failure, nearly collided with a storm of asteroids, got lost in the TARDIS corridors twice, wiped the memory banks of the flight computer, jettisoned three quarters of the storage hold and burned her cold dinner.
* BalefulPolymorph: Peri's forced transmutation into a bird creature.
* BondOneLiner: "Forgive me if I don't join you." -- said by the Doctor to some guards who are dying in an acid bath.
* BreadAndCircuses
* CrapsackWorld
* CuttingTheKnot: Faced with a complicated console and no idea which switches will deactive the transmogrificaton, Six simply shoots the console. (This became one of his defining moments for his CharacterDevelopment in AudioPlay/BigFinishDoctorWho.)
* DeadlyGame
* DeathCourse
* DramaticUnmask: When the Doctor rips off Quillam mask, and reveals the mess underneath.
* EveryoneCallsHimBarkeep: Neither the Governor nor the Chief Officer is ever referred to by name.
* EvilChancellor: The Chief Officer to the Governor. Slightly unusual example, in that it's immediately clear to both that the Chief Officer is both (a) the real power and (b) utterly venal, but unfortunately the Varosian system of government means the Governor's all but powerless.
* FamilyUnfriendlyDeath: A guard falling into a pool of acid (mostly notable because the Doctor seems to make a [[BondOneLiner mean-spirited quip]] about it afterward).
* GreekChorus: Arak and Etta, who are watching from their home.
* HeyItsThatGuy: Etta is [[Film/{{Brazil}} Mrs. Buttle]]. Jondar is [[Series/RobinOfSherwood Robin Hood]] to the Chief Officer's [[Series/MaidMarianAndHerMerryMen Prince John]], and the guard who throws in with the rebellion near the end is Will Scarlett (each from a different TV version of the Robin Hood legend).
* HobbesWasRight
* ImAHumanitarian: The mad escaped prisoners in the tunnels.
* MadScientist: Quillam, complete with a mask to hide his disfigurement.
* NonIndicativeName: The story features just about every negative human motivation except vengefulness.
* PenalColony: Varos used to be one of these. It's partly what makes it [[CrapsackWorld such a charming and lovely place in the present]].
* ProfessorGuineaPig: Quillam.
* PunchClockVillain: The Chief Officer.
* ReasonableAuthorityFigure: The Governor is in many ways a decent, fair and honourable man who genuinely just wants to do right by his people. Unfortunately, he's essentially a figurehead faced with a corrupt and venal [[EvilChancellor Chief Officer]], a ruthless and (literally) slimy CorruptCorporateExecutive and a system of government which is basically ''Series/TheXFactor'' voting system operated by a disengaged and unthinking population which can actually physically torture or even kill the Governor if he receives enough "no" votes. This tends to make things tough for him.
* LaResistance
* ServantRace: Sil's two flunkies are the only two black actors in the serial, which raises some UnfortunateImplications.
* SoWhatDoWeDoNow: Arak and Etta, at the very end.
* SpannerInTheWorks: The Doctor only lands on Varos in the first place because the TARDIS only has enough power for one flight and it's the nearest source of zeiton-7 he can find. He just happens to arrive during Jondar's execution, which creates a chain of events which ends up bringing down Varos' corrupt government.
* StrappedToAnOperatingTable: Peri and Areta, in the transmutation machine.
* TelevisedTorture: As both entertainment and warning.
* {{Unobtanium}}: The zeiton-7.
* VideoNasties: Sil likes making people watch these, and selling them to depraved residents of other planets.
* WalkingShirtlessScene: Jondar.
* YourMindMakesItReal: One of the deadly traps.
** Also basically how the transmutation machine works; it latches on to a thought in the subject's mind (say, "I want to be free!") and mutates the subject into a warped expression of that desire (turning them into a bird-creature so they can "fly away").
