-> ''"All these evils I have fought, while you have done nothing but observe! True, I am guilty of interference. Just as you are guilty of failing to use your great powers to help those in need!"''
-->-- '''The Doctor''' defends himself before the Time Lords.

The Doctor, Jamie and Zoe land in the middle of no-man's land during [[WorldWarI World War I]] - or so it seems. They're taken prisoner and tried as spies, with the Doctor sentenced to execution.

Once they manage to escape, (and get captured again, and escape ''again'', and...) they find out a couple of things are out of place: the soldiers don't seem to remember how they got to the front lines, there's a futuristic communications device in the General's quarters, and a redcoat of all people is thrown into a cell with Jamie - one who thinks he's still fighting the highlanders.

It turns out that a race known only as "The Aliens" have kidnapped a number of soldiers from Earth's history, brainwashed them and set them to fighting replicas of their own wars. The survivors will be made into an army capable of conquering the galaxy. They are aided by the War Chief, whom the Doctor recognises as being one of his own race, and who has provided the Aliens with [[FunWithAcronyms Sidrat]]s for transport purposes. However, the War Chief plans to double-cross the Aliens and seize power himself.

The Doctor and friends manage to gather a band of human resistance fighters (who were able to shake off the control of the Aliens and were wreaking havoc) to stop the wargames. The War Chief tries to get the Doctor to help him, but fails, and is shot by the Aliens' commander as repayment for his treachery.

However, the Doctor can't return all the surviving soldiers to their right places, so he calls on his own people, the Time Lords, for help.

They arrive and the Doctor is instantly put on trial for violating one of the Time Lords' prime directives - noninterference in other races' history. The Doctor argues that he has always done good, but to no avail. He is sentenced to exile on Earth, while Jamie and Zoe are returned to their own times, just before they met the Doctor, with their memories wiped. The Doctor is additionally informed that he must change his appearance again... and once the rules of regeneration were later established, these events can be construed as the Doctor's summary execution.

[[DownerEnding Yay.]]

-----

The final episode of this adventure is quite significant. As well as ushering in a new Doctor, and a new era in the show with budget-dictated Earthbound exile, this was the first time that the Doctor's race had been named, and that the reason for the Doctor's fugitive status had been explored. This is also the only time during the show's initial run that the Doctor and all of his companions changed at the same time. It wouldn't happen again for another [[Recap/DoctorWhoS30E17E18TheEndOfTime forty years]].[[note]]With HarsherInHindsight value! [[/note]]

Immediately after this episode aired, a series of official comics was released in TV Comic, exploring the idea of the Second Doctor spending a while longer with Jamie before regenerating. This series saw him living on Earth as well as running errands for the Time Lords with a fully functional TARDIS, before eventually being forced to regenerate. Although the canonicity of these comics (as well as later Franchise/DoctorWhoExpandedUniverse material based on the same idea) is still debatable, the [[http://www.bbc.co.uk/doctorwho/classic/episodeguide/season6b.shtml official BBC policy]] nowadays holds that [[Recap/DoctorWhoS10E1TheThreeDoctors "The Three Doctors"]], [[Recap/DoctorWho20thASTheFiveDoctors "The Five Doctors"]] and [[Recap/DoctorWhoS22E4TheTwoDoctors "The Two Doctors"]] would most logically take place in this "Season 6B" from Two's perspective.

With 10 parts totaling about 4 hours run time, this is the second longest serial (third if you count Season 23 as one whole) behind [[Recap/DoctorWhoS3E4TheDaleksMasterPlan The Daleks' Master Plan]].


!!Tropes
* TheAestheticsOfTechnology: This story subverts the usual BillionsOfButtons control panels by having the [=SIDRATs=] controlled with oddly-shaped fridge magnets. In a way, it somewhat foreshadows the touch-screens of the iPad and smart-phones (specifically, how one can touch, drag, and manipulate the icons on a screen).
* AffectionateGestureToTheHead: The Doctor kisses Zoe on the forehead in part 1.
* AllThereIsToKnowAboutTheCryingGame: It's the end of an era in many ways, and the first appearance of the Time Lords... but that's only at the end of a very long story which explores a war mystery and a conspiracy. Unfortunately, it now tends to be seen as loads of episodes of messing around before the Time Lords show up.
* UsefulNotes/AmericanCivilWar: One of the war zones.
* ArmyOfTheAges
* AsYouKnow: [[DefiedTrope Defied]] in the fifth episode. The chief scientist reminds the Doctor that the recruits, one of whom the Doctor was posing as, already know what the 'great plan' of the War Chief is. The Doctor doesn't bother asking him for specifics since it would blow his cover.
* BackForTheFinale: In part 10, Claire Jenkins briefly returns as Tanya from ''The Wheel in Space'', welcoming Zoe back as the latter returns to her own time.
* BaitAndSwitch: The Time Lords offer the Doctor a HopeSpot, by saying that they've accepted his plea that there is still evil that needs to be fought and he has a part to play in that. Then they inform him he's going to be exiled to 20th century Earth for as long as they deem proper, his knowledge of how to operate the TARDIS will taken from, and he will be put through a forced regeneration.
* BaitAndSwitchGunshot: Twice. The first time is during the Doctor's execution (a member of the firing squad is shot instead), the second is when the commander of the American civil war wants to shoot a rebel (he is shot by a half-brainwashed member).
* {{Bandito}}: Arturo Villar.
* BangBangBANG: The usual opening of a [[Creator/PatrickTroughton Troughton]] episode plays... his face melts into "DOCTOR WHO", and then, with thunderous and overwhelming clattering, the title cards appear, interspersed with StockFootage of UsefulNotes/WorldWarOne machine guns in action.
* BavarianFireDrill: The Doctor has been convicted of espionage in wartime and has escaped from prison. He is not in uniform, or even a proper suit, and he has a gaping hole in the knee of his trousers, and yet manages to bluff the prison commander for a solid chunk of time just by knowing what to say and shouting loudly.
* BittersweetEnding: Jamie and Zoe make it out alive. The Games are shut down. The War Lord and his cronies are killed. The War Chief [[TheNthDoctor seemingly]] dies. But, as the Doctor watches the Time Lords return Jamie and Zoe to their own times, promising they'll never forget him, he sighs in surrender, knowing [[LaserGuidedAmnesia they will]]. The Doctor is executed for his [[MysteriousPast various crimes]], and sent in exile to earth, stripped of his knowledge of time travel. [[GainaxEnding The final scene of the second Doctor's tenure is him tumbling into seemingly eternal darkness, screaming in horror as the Time Lords punish him.]]
* BookEnds: The serial begins and ends with the Doctor's execution.
* CallBack
--> '''Doctor''': ''Jamie, I need to pick this lock. ''
--> '''Jamie''': ''[[Recap/DoctorWhoS6E6TheSpacePirates Oh with a tuning fork?]]''
** During the Doctor's trial by the Time Lords, he shows them some of the most dangerous monsters he has been fighting, among them the Cybermen, Daleks, Ice Warriors and Yeti.
* CoolVersusAwesome: [[UsefulNotes/WorldWarOne British army]] versus [[UsefulNotes/AmericanCivilWar Union army]]! [[UsefulNotes/TheRomanEmpire A Roman century]] chasing [[UsefulNotes/WorldWarOne a British ambulance]]! [[UsefulNotes/AmericanCivilWar Union and Confederate troops]] versus [[UsefulNotes/TheMexicanRevolution Mexican Revolutionaries]]! [[ArmyOfTheAges All of them]] versus Aliens and Steve Jobs!
* ComfortingComforter: Jamie, to a sleeping Zoe.
* DastardlyWhiplash: The War Chief is a traditionalist, at least as far as his grooming habits go.
* DownerEnding
* EarlyInstallmentWeirdness: When told he must sacrifice one regeneration, the Doctor's only concern is what he'll look like in his next life. This looks very strange to those who watched [[Recap/DoctorWhoS30E17E18TheEndOfTime "The End of Time"]], where Creator/DavidTennant's Doctor fears his imminent death and considers regeneration a close approximation of death. Unless he's stalling for time...
** CharacterDevelopment. Coupled with the fact that at least the Time Lords and the potential for rescue still existed when Two was forced to regenerate and exiled.
** And the Doctor was only on his second body, as opposed to his [[DoctorWhoS33E13TheNameOfTheDoctor eleventh]], of thirteen.
* EnemyMine: The Resistance includes soldiers from opposing sides, starting with Jamie and the Redcoat.
* EvilCounterpart: The War Chief [[LateArrivalSpoiler is a Time Lord]] scientist who stole a Tardis and [[{{Foreshadowing}} is serving as scientific adviser to a military program]], and [[MookHorrorShow is trying to keep things at the base steady while hostile aliens surround it and attempt to penetrate its defenses.]]
* {{Foreshadowing}}:
** Boy, [[Recap/DoctorWhoS7E1SpearheadFromSpace the Doctor sure seems to work well with the military]], doesn't he?
** Likewise, [[Recap/DoctorWhoS8E1TerrorOfTheAutons this rival renegade Time Lord]] with the DastardlyWhiplash grooming habits and black nehru jacket and the MindControl powers certainly seems like a character archetype worth seeing again.
* FourEyesZeroSoul: All of the aliens exert their MindControl by using glasses
* FromBadToWorse: The TARDIS lands in UsefulNotes/WorldWarOne. [[SerialEscalation And then it gets worse.]]
* GlassesPull: How General Smythe exerts MindControl over his inferiors. His German/Confederate equivalent uses a Monocle Pull.
* GodzillaThreshold: When it becomes clear that, despite having brought the Games to a screeching halt, the Doctor cannot actually fix the situation that has resolved all on his own, he's forced to call upon the Time Lords to sort things out and to punish the guilty. [[HeroicSacrifice Including himself.]]
* GrandFinale: For the Creator/PatrickTroughton era.
* TheGuardsMustBeCrazy: At every level of the exercise. The guards at the prison let Jamie and the Redcoat prisoner escape because of a fake tussle, and almost let the Doctor [[BavarianFireDrill talk his way right into their corridors and then right back out.]] Later, a pair of the War Lords' guards seemingly fail to notice the Doctor directly in front of them as he's sneaking down a hall.
* HamToHamCombat: Put the security chief and the War Chief in one room. Watch as they argue and completely devour the scenery.
* HoistByHisOwnPetard: The Doctor uses these exact words (almost) of the scientist whom he turns the processing machine on.
* InsignificantLittleBluePlanet - [[LampshadeHanging Lampshaded]] by the Time Lords.
* KangarooCourt: During the court-martial, the Doctor is allowed to question the witnesses, but they aren't allowed to answer. When this doesn't convince the two other jury members, Smythe just {{MindControl}}s them.
* LargeHam: A few characters get moments. The Security Chief would be a Ham if he ever figured out that he wasn't a Dalek. Villar is a textbook Ham.
* MindControl
* MistakenForSpies: systematically, by every single group of people they meet.
** Including the Aliens' Security Chief - who is half-right. (The Doctor is not working with the War Chief, but he IS a member of his race.)
* MookHorrorShow: If you squint a little, this is a Base Under Siege story with the Doctor and the humans as the monsters.
* MysteriousPast: As befitting his [[EvilCounterpart role in the story]], the War Chief has a mysterious past involving the circumstances of his leaving Gallifrey and how he knows the Doctor. Amongst the intriguing clues, he recognizes the Doctor immediately on sight, and is also familiar with the Doctor's professional work on Gallifrey. Later ExpandedUniverse works suggest either EveryoneWentToSchoolTogether or else he's [[CompositeCharacter actually the first appearance of the Master.]]
* TheNthDoctor: [[PlayingWithATrope Played with.]] We see several possible faces for the Doctor to take, complete with his objections to them, and we see him [[EpilepticTrees maybe]] begin to regenerate, but the actual change from Troughton to Pertwee never happens onscreen.
* OhCrap
* OurDoorsAreDifferent: The Security Chief's door is designed to evoke a guillotine blade.
** The [=SIDRATs'=] doors slide outward rather than to one side.
* ReasonableAuthorityFigure: [[SufficientlyAdvancedAliens The Time Lords]], guardians of history. They sort out the troubles with the Games and return the survivors to their correct times with LaserGuidedAmnesia to keep the events secret. Sure, they also find the Doctor guilty of [[AlienNonInterferenceClause meddling in the affairs]] of the less advanced races, but they [[{{Understatement}} basically give him parole and community service.]] Also, considering we see in this serial how dangerous a renegade Time Lord can be, their non-interference except for very important events makes sense.
* RefugeInAudacity: The Doctor pretends to be a prison inspector from the ministry.
* SdrawkcabName: SIDRAT. The [[Literature/DoctorWhoNovelisations novelisation]] gives us a [[FunWithAcronyms backronym]]: They're Sidereal Interdimensional Robot All-purpose Transporters.
* SlouchOfVillainy: The War Lord. The War Chief tries to imitate it.
* TheStarscream: The War Chief plans to overthrow the War Lord. He is RewardedAsATraitorDeserves.
* StarterVillain: Smythe acts as the main antagonist for the first few episodes before his superiors reveal themselves.
* StayInTheKitchen:
--> '''Jamie''': ''Lady Jennifer I don't think you should come.''
--> '''Lady Jennifer''': ''Because I'm a woman?''
--> '''Jamie''': ''Yea... No! Err... Well, in a way yes.''
** Arturo refuses to listen to anything Zoe says and mocks Jamie for "listening to a woman".
* StockEpisodeTitles: 14 uses.
* StuffBlowingUp: The story is seemingly set in UsefulNotes/WorldWarOne, so yes. Also, the Doctor "picks a lock" this way.
* SummonBiggerFish
* TapOnTheHead: Zoe takes out the sergeant with a vase of flowers. Unlike most uses, however, the Doctor checks to make sure he's okay afterwards. Jamie also knocks out a few soldiers this way.
* ValuesDissonance: [[{{In-Universe}} In-story]], between the soldiers from each different time zone.
* TheWallsAreClosingIn: Done to the occupants of a SIDRAT (including the Doctor).
* TrrrillingRrrs: The Mexican characters do this constantly, and the War Chief does so too every now and then.
* WarIsHell: [[ExactlyWhatItSaysOnTheTin Pretty much.]]
* WellIntentionedExtremist: The War Chief tries to come across as one, claiming if the Galaxy is conquered there can be peace.
* WhatHappenedToTheMouse: Lady Jennifer disappears about halfway through. Later, Lieutenant Carstairs says he wants to look for her, but he disappears (in a more literal sense) before he can. WordOfGod on the DVD commentary says that when they returned to Earth, he did find her. And married her.
* WhamEpisode: The Doctor's race is named for the first time, and he's forcibly regenerated and exiled to Earth. The next episode will air with a completely different cast (except for a [[Creator/NicholasCourtney guest star]] promoted to full cast member), a different premise, a new backstory for the character, [[ArtShift and in color.]]
* UsefulNotes/WorldWarOne: "The War Games" opens here -- or so it seems.
