-->-- '''The Master'''

The TARDIS arrives in the year 2540 on board an Earth freighter which comes under attack. The crew seem to think that the Doctor and Jo, along with the other attackers, are Draconians - a reptilian race who are the major rivals to Earth's empire. The Doctor and Jo, however, can see that the attackers are really Ogrons - the ape-like heavies employed by the Daleks in "[[Recap/DoctorWhoS9E1DayOfTheDaleks Day of the Daleks]]".

The Ogrons overwhelm the shop and steal the cargo, including the TARDIS. The Doctor and Jo are accused of being Draconian spies. The Doctor is sent to a penal colony, while Jo is placed in the care of "the Commissioner from Sirius 4" - actually the Master. The Master rescues the Doctor from the penal colony and imprisons him and Jo aboard his stolen spacecraft, revealing he plans to spark a war between Earth and Draconia using Ogron mercenaries and a hypnotic device that makes the spaceship crews perceive them as whatever they most fear.

However, the ship is intercepted by Draconians and the Doctor is able to convince the Draconian Emperor of the Master's plans before being recaptured by Earth forces, while Jo is recaptured by the renegade Time Lord and taken to the Ogron planet, where the TARDIS has been taken. A Draconian prince who was with the Doctor reveals an Earth General was responsible for the previous war. Wanting to make amends, the General, the Prince, and the Doctor travel to the Ogron Planet and it is revealed that the real force behind the plot is not the Master, but the Daleks, who wish to conquer the Galaxy in the aftermath of the planned war.

The Doctor escapes and manages to get the Prince and General away before being injured in the confusion. Jo helps him to the TARDIS as he sends a telepathic message to the Time Lords.


* BBCQuarry: Of course the Ogron planet is another rock quarry.
* BlatantLies: The Master claims nobody wants peace more than he does.
* BorrowedCatchphrase: The Doctor borrows the Master's "Oh no, you don't" when the latter tries to get his gun back.
* CallBack: The Master, after capturing the Doctor, mentions the Doctor visiting him when he was [[Recap/DoctorWhoS9E3TheSeaDevils imprisoned by UNIT]]. A bit later in this same scene, the Doctor masks his attempt to escape by droning on about everything that happened to him since [[Recap/DoctorWhoS6E7TheWarGames his exile]].
** Incidentally, he relates the trial [[HerCodeNameWasMarySue a little differently]] from the version the audience remembers.
* CharacterOutlivesActor: Roger Delgado was to make one last appearance after this serial as The Master in a story where he ultimately [[HeroicSacrifice gives his life]] [[RedemptionEqualsDeath to save the Doctor and the universe]]. However, after completing this serial, Delgado was killed in a car crash in Turkey. The last we see of the Master is his dastardly escape after shooting the Doctor. The character would not be seen again until "[[Recap/DoctorWhoS14E3TheDeadlyAssassin The Deadly Assassin]]", when he would be a dessicated, nearly-unrecognizable husk some four years later.
* CliffhangerCopout: PlayedWith. The ending of Part 5 has the Master (after failing to the normal way) turn on the hypnosound as a means of taking over Jo's mind ([[Recap/DoctorWhoS8E1TerrorOfTheAutons again]]). Episode 6 has Jo ''struggling'' not to succumb, and ultimately holds out long enough for the Master to just turn it off and order her taken away.
* ContinuityCavalcade: When the Master subjects Jo to the fear inducing machine, she sees him as [[Recap/DoctorWhoS10E2CarnivalOfMonsters a Drashig]], [[Recap/DoctorWhoS9E4TheMutants a Solonian]] and [[Recap/DoctorWhoS9E3TheSeaDevils a Sea Devil.]]
* CouldSayItBut: The Draconians get around ordering anything illegal like this.
-->'''Aide:''' Prisoners have been known to escape, your Highness.
-->'''Prince:''' Not without help. And that would be a grave act of hostility. I could not possibly countenance such a plan.
-->'''Aide:''' But should two escaping prisoners seek sanctuary in this Embassy, it would be uncivilised to turn them away.
-->'''Prince:''' (pause) I must not detain you longer. No doubt you have duties demanding your attention?
* ContinuousDecompression: The door of a spaceship is open, and the crew still have time to slowly come from another room and close the door before they run out of air.
* DangerouslyGenreSavvy: The Master seems to know most tricks in the book.
* DeadpanSnarker: After the Master tries to convince the Draconians he's peaceful, the Doctor asks him whether he feels sick.
* DeliberateValuesDissonance: Between the humans and Draconians. Draconians don't allow females to speak publicly, humans have a female president. Humans are quick to accuse, Draconians- at least the elders- are more reserved and reasonable.
* FalseFlagOperation
* FantasticSlur: Dragon, for Draconians.
* FeudalFuture: The Draconians feature an emperor and nobles.
* FriendlyFire: While on the way to the Ogrons planet, the Earth ship is attacked by Draconians. The Draconian Prince says the Officer will be punished, but the Doctor points out they are infringing on Draconian space.
* {{Foreshadowing}}: The Master's chest badge hints at the nature of his employers; it's a stylised Dalek.
** The monster that scares the Ogrons away in the last episode also appears as a statue before we get any explanation.
* FreezeFrameBonus: The screen in Madam President's office first shows a news message.
-->Reports are coming in of Anti-Draconian riots in Tokio. No loss of life but property extensively damaged. In several other cities-
** Later on, it shows a list of the Doctor and Jo's crimes.
* GeneralRipper: The crazy and paranoid General Williams is one of these, as contrasted to the more reasonable Earth President. Subverted later on in the story however, as it turns out that the incident that led to his hatred of the Draconians actually came about from a misunderstanding, and from then on he acts far more reasonably towards them.
* GenreSavvy: The Master knows better than to take the Doctor's almost certain death for granted.
* HijackedByGanon: Done '''twice'''. The Ogrons are quickly revealed to be working for the Master, who turns out in the final episode to have been working for the Daleks.
* HoldingTheFloor: To distract the Master from the Doctor's escape, Jo relates about her entire life to the camera.
* HypnoticEyes: Unfortunately for the Master, Jo has learnt how to resist this, by filling her mind with {{nursery rhyme}}s -- the Master gives up out of sheer annoyance.
* IKnowWhatYouFear: The Master's hypnosound causes this. Humans and Draconians see each other. Jo sees a creature from a past adventure.
** LettingTheAirOutOfTheBand: What happens to the Master's [[BackgroundMusic BGM]], in conjuncture with the above trope.
* KarmaHoudini: The Prison Governor and Cross, both of whom conspired to assassinate the Doctor and make it look like an escape attempt gone bad.
* TheManBehindTheMan: The Master is revealed as the Ogrons' employer. He is, in turn, working for the Daleks.
* TheMaster
* MindProbe: When one is used on the Doctor it ends up being destroyed when General Williams refuses to accept it as truth. The Doctor talks of a NoodleIncident where he was captured by the Medusoids and broke the mind probe. He was freed when the Medusoids ran out of mind probes.
* NoodleIncident: 2 are quite prominently mentioned by the Doctor. While on the way to the 3rd intergalactic peace conference he was captured by the Medusoids, hairy one-eyed jellyfish, and under the Mind Probe truthfully told them he was on his way to meeting a giant rabbit, a pink elephant and a purple horse with yellow spots. The machine self-destructed from this, and he was freed when the Medusoids ran out of mind probes. Later he reveals he was made a nobleman of Draconica by the 15th Emperor who ruled 500 years ago, when he saved the Draconians from a plague from space.
* NoSeatBelts: Averted in the cargo ship, though the design isn't that appropriate for a space ship.
* OhCrap: The Doctor and Jo immediately know something is wrong when the Master becomes agreeable during their meeting with the Draconian Emperor.
* OnceAnEpisode: The Doctor, Jo or either one is imprisoned by one of the various factions who appear in this serial.
* PsychicStatic: How Jo resists the Master's initial mind control attempt.
* ReasonableAuthorityFigure: Both the president and the emperor.
* RightMakesMight: The Master claims that he's not afraid at one point due to this trope. Since he's very much in the wrong, it's really the tracking signal on him that his minions are following that reassures him.
* ShoutOut: The Master is reading ''Literature/TheWarOfTheWorlds''.
* SpaceClothes: Both Earth-men and Draconians have clothes with big shoulder pieces and collars.
* SpaceColdWar
* SnakeTalk: The Draconians have a somewhat subdued version of snake talk, mostly hissing if a word ends on an 's' sound only.
* StageWhisper: The professor and Cross discuss an escape plan standing barely a few feet away from a guard. But then again, Cross wasn't really trying to get the professor free, so the guard could have known it was a trap.
* TheStarscream: The Master.
* TitleDrop: "The treaty between our two empires established a frontier in space. We have never violated that frontier."
* UnspokenPlanGuarantee: When the Doctor explains to Jo how they will escape from their cell, all he says is: "So this is what we're going to do..." Cut to execution of the plan.
* VSign: The standard greeting among Peace Party members.
* WarForFunAndProfit: A classic example of the trope, as the Master uses a whole bunch of {{False Flag Operation}}s to try to provoke war between Earth and Draconia.
* WhatAreYouInFor: But the prisoner asking it already knows everybody is a political prisoner.
* WhipItGood: The Doctor chasing the Master around a spaceship with a belt. Yes.
* WireFu: The 'weightless' scenes on the outside of the spaceships are done with [[SpecialEffectsFailure (quite visible)]] wires.
* WomenAreWiser: Of all humans, Madam President is at least somewhat willing to listen to the Doctor's explanation of things, unlike the men who surround her.
* {{Wutai}}: Draconia is basically feudal Japan in space with reptile people.
* {{Zeerust}}: The spaceships' cockpits don't exactly look modern, but the designs do contribute to the appearance of rugged space cruisers designed carrying out grunt work rather than looking flashy and comfortable.
