The Doctor tells Martha that her one trip is over, and she can go home now... unless she wants to travel more. No reason, really, he'd just like to travel more. In fact, he'd like to take her to the future — and how about another planet? Martha is all for it, but throws him by asking if they can visit ''his'' home. Planet of the Time Lords, after all; got to be worth a look? The Doctor finds himself agreeing, fondly recalling the burnt orange sky, mountains covered in red grass, a gleaming city under its mighty glass dome...

... but nah, why would he want to go back there? Better idea: New New New, etc., York. Where drugs are cheap, legal and socially acceptable. Where people inexplicably look like cats. Where traffic never moves. [[Recap/DoctorWhoS28E1NewEarth Where the Doctor also took Rose once.]]

The Doctor even tries to make the same little jokes he made to Rose when he first took her there, but they just don't work as well when Rose isn't around to hear them. By now, Martha's figured out that she's the Doctor's "rebound", and she doesn't like it one bit. Also, the TARDIS has taken them to the undercity slums, where things aren't quite as happy as they are above the smog.

Martha gets kidnapped by a couple named Milo and Cheen so that they can have enough people in their car to get access to the elusive fast lane. The Doctor chases after her... into the Traffic Jam from Hell.

Before he dies of extreme toxic smoke inhalation, though, he gets picked up by [[CatFolk Thomas Kinkaide Brannigan]] and his wife Valerie. Estimated time of arrival? Oh, another six years or so.

The Doctor, not wanting to wait that long, jumps from car to car, and tries climbing down to Martha's spot, but he can only get so far.

Meanwhile, [[Recap/DoctorWhoS4E7TheMacraTerror giant evil crabs that feed off pollution]] have snatched Martha's car out of the air and are hell-bent on eating her. The Doctor quickly recognizes them as the Macra and notes that they've devolved into mindless beasts over time, living in the depths of the motorway. Even if he could get there, there's hardly any way to get back.

The Doctor will not be deterred, but before he can continue he's caught by Novice Hame, one of the cat-nurse-nuns he met during his last trip here. She transports him against his will to the upper city, where the only other remaining "person" is the Face of Boe, the oldest being in the galaxy, who's the only thing powering the motorway and keeping the rest of demi-humanity alive. It turns out that the planet's inhabitants all got wiped out by an unstoppable plague that killed everyone (including itself). And all the motorways are closed, and have been closed for years. All those cars with all their eternal fuel and food supplies are driving in eternal circles around the deadly city smog.

The quarantine placed on the planet was set to last 100 years, so it has to be released manually. The Face gives his life to open up the motorway exits and save Martha. The Doctor opens the gates and all the cars ascend into the bright upper city, with the people inside praising Jehova for saving them from the Macra.

As the Face dies, he imparts his final message, as foreshadowed in "[[Recap/DoctorWhoS28E1NewEarth New Earth]]". The message? "[[Recap/DoctorWhoS29E11Utopia You are not alone.]]"

Martha refuses to leave until the Doctor tells her just what he is and what's going on. The Doctor sits down with her and tells his story from the beginning, starting with "there was a war"...

!!Tropes:

* AbsurdlySharpClaws: The Macra can be found at the bottom of the motorway in New New York. In the "fast lane" you can reach speeds of up to thirty miles per hour! (Usually taking six years to get to Brooklyn from Queens!) However, this comes with a risk: the potential of being sliced and mauled by the Macra. What's even scarier is that you only really get to see these claws above the fumes.
* ActionPrologue: The episode begins with a couple's flying car on a motorway being attacked by an unseen menace.
* AdventurerOutfit: Brannigan is wearing goggles, a scarf and a leather jacket. He's basically a suburban dad.
* AdultsAreMoreAnthropomorphic: We meet an interspecies couple — human female and catman male. They recently had a litter of children who all look like normal kittens (because they were all played by kittens).
* AliensOfLondon: Despite being New New York, everyone there (barring Brannigan and the news anchor) sounds very British due to the TARDIS' TranslationConvention.
* AlienSky: As the episode ends, the Doctor describes Gallifrey's sky, and the way when the red of the sun hit the silver trees it looked like the sky was on fire...
* AllThereInTheManual: As to how the Macra ended up in the motorway in the first place, they were in New New York's zoo, and got free when everyone else died.
* AlwaysSaveTheGirl:
-->'''Brannigan:''' This Martha... she must mean a whole lot to you.\\
'''The Doctor:''' Hardly know her. I was too busy showing off.
* AmericanGothicCouple: The couple in the opening who are attacked by the Macra look like this, but they are far from stoic. They are terrified.
* ApocalypseHow: ThePlague from the Bliss drug has wiped out literally everyone on New Earth who wasn't sealed off in the Undercity or, in the Face of Boe and Novice Hame's case, protected by the Face's smoke, making the disaster a ApocalypseHow/Class2. If Novice Hame's statement that "everything perished, even the virus in the end" is taken literally (since we only see the metal city and don't see if the apple grass from New Earth's previous appearance is still alive), then the disaster is more of a ApocalypseHow/Class5 for everything outside the Undercity.
* ApologeticAttacker: Martha's kidnappers frantically say "sorry" to the Doctor even as they drag Martha off.
* ArtImitatesArt: Ma and Pa were based on the farming couple in the painting American Gothic, both having identical hairstyles, glasses and fashions.
* TheAtoner: Novice Hame, the cat nun assistant to the Face of Boe, was the survivor out of the three named cat nuns from "[[Recap/DoctorWhoS28E1NewEarth New Earth]]".
* BackForTheDead: The Face Of Boe, last seen at the beginning of the previous series, returns in time to sacrifice himself to rescue the people trapped on the motorway.
* BigBad: The Macra are the main threat, although they didn't cause the situation, it just works to their advantage.
* BigWordShout: [[SayMyName MAAAAAAAARTHAAAAAAAAAAAA!]]
* BinarySuns: The Doctor talks about Gallifrey's in the beginning.
* CatFolk: The Sisters of Plenitude weren't the only inhabitants of New New York to be cat-people, and in this episode we see several more, most prominently Brannigan.
* ContinuityNod:
** [[Recap/DoctorWhoS4E7TheMacraTerror The Macra]]. From a MissingEpisode, no less.
** The Doctor asks for the Duke of Manhattan, who he met on his previous visit.
** One of the car drivers is a completely red dude — we saw another one in "[[Recap/DoctorWhoS28E1NewEarth New Earth]]".
** Part of the Doctor's description of Gallifrey matches that of Susan's from "[[Recap/DoctorWhoS1E7TheSensorites The Sensorites]]".
* CrapsackWorld: The other side of New New York isn't a nice place. Due to the exhaust buildup the air is filthy, millions of people are trapped in their cars for ''years'' (if they ever get to their destination at all), and if you go down into the fast lane you stand a very good chance of being eaten by the Macra.
* TheCityNarrows: The other side of New New York is less dazzling than the previous.
* CuteKitten: The cute factor is the most likely reason for an anthropomorphic cat and a demi-human woman having a litter of seemingly ordinary kittens. It's likely that Catkind children all look like this and become more anthropomorphic as they age.
* DeadHandShot: The prologue has one as one of the car inhabitants slaps their bloody hand against the screen while being killed by the Macra.
* DeathOfAChild: The second car on-screen to fall victim to the Macra is a car carrying two young twins.
* DiscoDan: The Cassini "sisters"; they're old ladies born in the far future and they still decorate their car stereotypical for the 30s-40s.
* DominantSpeciesGenes: We briefly meet a [[CatFolk Catman]] and human female husband and wife, who have a litter of kitten offspring.
* DrugsAreBad: Both Martha and the Doctor are unamused by a street populated by drug-dealing booths that sell everything from "Happy" to "Forget" to "Honesty", and a contaminated batch of "Bliss" killed all of New Earth's population apart from New New York's undercity.
* ElephantInTheLivingRoom: No one wants to talk about why they've never seen any emergency vehicles.
* EverybodysDeadDave: A virus that started off in a drug spread across the entirety of New Earth, killing everyone it came into contact with. The people in the undercity survived because they were sealed off before the virus could get to them, and Novice Hame only survived because of the Face of Boe.
* EvolutionaryLevels: The Doctor wonders if the Macra have devolved, considering they used to be intelligent but now they're just huge mindless monsters.
* EvolutionaryStasis: Despite being said in previous episodes to have changed, the humans still look human.
* FateWorseThanDeath: Going to the motorway is grim indeed. Sitting in the eternal traffic jam, going round and round year upon year upon decade, with the only interaction being with whoever you already have with you or can phone. And everyone goes to the motorway in the end.
* FirstTimeInTheSun: After spending their lives on an underground motorway, the inhabitants of New New New (etc.) York are enthralled when the Doctor fixes the transport system so that they can fly up into the sky and city for the first time.
* FlatWhat: Martha's displeased and surprised reaction to the length of time a ten-mile/sixteen-kilometre journey will take.
* FlyingCar: In sufficient abundance to result in three-dimensional multi-lane motorways and horrifying flying traffic jams.
* {{Foreshadowing}}: The Face of Boe's last words:[[note]]foreshadowing both the return of the Master and, much more indirectly, that the Face is Captain Jack in the future.[[/note]]
-->"I must. But know this, Time Lord: YouAreNotAlone."
* FormerlySapientSpecies: In the ages since their first appearance, the Macra have "devolved" (in the Doctor's words) since their first appearance from powerful, mind-controlling creatures to beasts who live only to feed.
* FuturisticSuperhighway: The Doctor returns to the planet New Earth to discover one of these in the city of New New York stuck in a massive traffic jam because the entire population of the rest of the planet died in a virulent plague, and the undercity, including the motorway, was sealed off to protect the population. Afterward, there wasn't enough power to reopen it. If that wasn't bad enough, there are devolved Macra which escaped from the zoo living on the bottom of the pollution-choked tunnel waiting to snatch anyone who tries to use the 3-person "fast lane".
* GiantEnemyCrab: The Macra. They can be found at the bottom of the motorway in [[NewNeoCity New New York]] (on New Earth). In the "fast lane", you can reach speeds of up to thirty miles per hour! (Usually taking six years to get to Brooklyn from Queens!) However, this comes with a risk: the potential of being sliced and mauled by the Macra. What's even scarier is that you only really get to see the claws above the fumes.
* HalfHumanHybrid: Brannigan has children with a human woman. They look exactly like normal kittens.
* HandOrObjectUnderwear: The woman in the "nudist" car is holding a magazine when the Doctor drops in.
* HappilyMarried: There are two (maybe three) married couples in this episode and they all get along well for being stuck together in a small car for decades.
** Brannigan and Valerie playfully bicker.
** The Cassinis hold hands during the hymn.
* HeroicSacrifice: The Face of Boe sacrifices himself to provide enough energy to open up the motorway in which the last surviving citizens of New New York are trapped, releasing them from both the doomed fate of driving on the motorway forever and from being preyed on by the Macra below. Specifically, this saves the life of Martha and numerous other minor characters met throughout the episode who are stuck in cars on the motorway with no escape.
* HoodHopping: The Doctor does a three-dimensional version to find Martha in the traffic jam.
* HypocriticalHumour: Brannigan refers to the Cassinis as "sisters", claiming that he's a traditional type despite being a catman married to a humanoid.
* IAteWhat: Martha is disgusted to learn that food in the cars is made from recycled waste, after taking a few bites of a cracker offered to her.
* InterspeciesRomance: The Brannigans. She's demi-human, he's a cat-man; their kids are a litter of kittens ([[RuleOfCute who can say "Mama"]]).
* LaserGuidedAmnesia: "Forget", with variable amounts of amnesia dependant on just how much the buyer wants to forget. The Doctor and Martha meet a young woman buying some when her parents have gone to the motorway, and are unable to stop her applying the patch.
* LiarRevealed: At the end, the Doctor is forced to come clean about the fact that he's the LastOfHisKind, which he had previously been trying to keep Martha unaware of.
* MuckMonster: The Macra live in and feed on car smog.
* NakedPeopleAreFunny: As the Doctor tries to track down the carjackers who took Martha, one of the couples occupying the cars he climbs through is a pair of nudists. He doesn't hang around long enough to bother giving them an alibi.
* NationalStereotypes:
** Irish Catman.
** That one guy who ''really'' went out of his way to look [[IAmVeryBritish British]]. Bowler hat, something about manners...
* NewNeoCity: New New New New New New New New New New New New New New New New York. Again.
* NoAntagonist: A rare ''Doctor Who'' story with no sentient villain. Even the virus that wiped out the entire population of New Earth has long since perished, having had no one left alive to infect and propagate itself with.
* NoodleIncident: The Doctor's meeting with Music/JanisJoplin that led to her giving him his BadassLongcoat is only mentioned in brief.
* NoProductSafetyStandards: The future society nearly collapsed because of drugs that "blissed" you to death.
* NothingIsScarier: We don't really see the Macra beyond their claws and [[ByTheLightsOfTheirEyes eyes]]. Makes it all the more terrifying whenever they peel open a car like a tin can and eat the people inside.
* OneDrinkWillKillTheBaby: When Martha finds out that Cheen is pregnant, she rips off Cheen's Honesty patch in disgust.
* OneSteveLimit: Cheen's boyfriend isn't the first [[Recap/DoctorWhoS28E3SchoolReunion Milo]] to appear in the new series.
* OneWordTitle: "Gridlock".
* PoliceAreUseless: A call to the police gets the Doctor put on hold. A call to the Cassinis reveals that there ''aren't'' police.
* ThePlague: The Bliss Virus began as a recreational drug and then mutated. It turned deadly and spread to the entire population, only dying when it couldn't reach the motorway.
* PlanetOfHats: All of the cars the Doctor passes through have obvious themes, be they white décor, Harajuku fashion, hippy nudism, red décor, or stylish fifties Britain.
* {{Pun}}: "If it's any consolation, Valerie, right now I'm having kittens."
* RuleOfThree: In order to use the fast lane, you have to have three passengers. Lie to the computer, and your car is shut down. In TheTeaser, the woman of the AmericanGothicCouple believes that her husband lying to the computer about there being three people aboard is the reason for their plight, and the entire reason Martha is kidnapped is so that the couple she's with can get to the fast lane.
* RussianReversal: In New New New New New New New New New New New New New New New York, carjackers steal ''you''.
* SameCharacterButDifferent: The Macra were originally hyperintelligent, spacefaring crab monsters with hypnotic powers. They return forty years later as much bigger crab monsters that are no longer sapient and have no psychic powers. The Doctor claims that they've devolved into dumb animals over billions of years in the far future.
* SawItInAMovieOnce: Martha persuades the driver of an air car to shut down all systems (including the much-needed air purifier) so that the large monsters in the poisonous fog won't find them.
-->"I saw it on a film. They used to do it in submarines. The trouble is, I can't remember what they did next."
* SelectiveObliviousness: Everyone is aware on some level that they've not seen any sign from the government and/or the people on the surface for over 20 years, but it takes some serious prodding from the Doctor before they even start to acknowledge the ElephantInTheLivingRoom.
* SequelEpisode: The final part of the "New Earth" trilogy.
* SeriesContinuityError: In "[[Recap/DoctorWhoS28E1NewEarth New Earth]]", the Doctor says the titular planet is in the galaxy [[https://en.wikipedia.org/wiki/Messier_87 M87]]. In this episode, he says it's 50,000 light-years from the former location of Old Earth. That's a difference of over ''fifty million'' light-years, even accounting for the episodes being set five billion years in the future.
* ShoutOut:
** According to WordOfGod[[invoked]], the concept of an endless traffic jam in a dystopian city is a shoutout to Mega-City One in ''ComicBook/JudgeDredd'', and the man with the bowler hat is based on Max Normal, a supporting character in the comic.
** Sally Calypso is an homage to [[ComicBook/TheBalladOfHaloJones Swifty Frisko]].
** Ma and Pa at the start of the episode are based on the farming couple in the painting ''American Gothic'', both having identical hairstyles, glasses and fashions.
** Apparently, the Doctor's coat was a gift from Music/JanisJoplin.
** Brannigan's appearance was based on "Ratz", the CGI disembodied cat's head that was a "virtual presenter" of CBBC's ''Series/LiveAndKicking'' in the early 1990s.
* TheSlowPath: It's been several decades for Novice Hame and only a year or so for the Doctor since they last met, something Hame points out.
* SongOfPrayer: The people stuck in the Motorway sing hymns, particularly "The Old Rugged Cross", as a way to keep up their spirits. After the Doctor finally releases the exits, they start singing "Abide With Me", a hymn asking the Lord to come and stay for a time.
* TakeThat: To metropolitan traffic jams in general, London in particular. The people on the Motorway think travelling 5 miles in 12 years is making good time.
* TeleportationSickness: "Rough teleport. Ow."
* TookALevelInKindness: The Doctor, following his [[HeelRealisation realising how badly he's treated Martha]], comes clean with her about Gallifrey.
* UnusuallyUninterestingSight: The people on the underground motorway are disturbingly blasé about the fact that nobody ever gets anywhere, that there's no police, and that the news doesn't do anything special. Martha needs to take a bit of time to adjust to this. This helps to make people never question ''what'' happened: the surface got wiped out by a virus.
* VillainDecay: Deliberately invoked. After a few billion years, the Macra devolved into a much less intelligent form, so instead of being invisible puppet masters (like the Silence would be later in New Who), they're just giant crabs living on car fumes.
* WhatTheHellHero: Martha gives the Doctor a minor one, making it clear that she will not stand for his lying and obfuscating.
* YouAreNotAlone:
** So says the Face of Boe.
** Everyone in the traffic jam; they're stuck in a dismal situation, but form a genuine community in spite of that. This is most obvious during the hymn scene.
--->'''Brannigan:''' You think you know us so well, Doctor. But we're not abandoned. Not while we have each other.
