''Resident Evil: Extinction'', the third film in the live-action ''Franchise/ResidentEvil'' film franchise, takes place a few years [[Film/ResidentEvilApocalypse after the events at Raccoon City]]. The world has become a desolate wasteland after the global spread of the T-Virus, and Alice has become a recluse due to fears concerning psychic abilities created by her own T-Virus infection. During her seclusion, she intercepts a transmission that mentions Arcadia, a place in Alaska alleged to have no trace of the T-Virus.

Meanwhile, a group of survivors led by Carlos, LJ, and [[Videogame/ResidentEvil2 Claire Redfield]] struggle to stay alive in the zombie-infested wastelands. Alice joining the group and the news of Arcadia come as a spotlight through the darkness, but with only meager supplies and makeshift vehicles, the survivors are left wondering how to reach the safe haven.

While Alice and her crew work to figure out a way to Arcadia, Umbrella scientists in an underground laboratory begin running experiments on domesticating zombies. One of them, Dr. Isaacs, needs Alice's blood to concoct a new strain of the T-Virus--and it just so happens that Alice is in the "neighborhood"...

[[Characters/ResidentEvilFilms Character Sheet here]].

----

!! ''Resident Evil: Extinction'' contains examples of the following tropes:

* AfterTheEnd: In ''Extinction'', the T-virus has contaminated and destroyed nearly all life on Earth.
* AGoodWayToDie: Carlos Oliveira is bitten by a zombie, so he decides to clear a way into Umbrella's desert compound for the other survivors. He does that by driving (and crashing) a tanker truck into a giant horde of zombies, then triggering an explosion that destroys a large portion of the zombie horde surrounding the compound. The best part? He finds a marijuana joint (well after the whole survivor convoy ran out of cigarettes) and manages to take a puff just before he blows up.
* AllThereInTheManual: The fate of Angela Ashford, last seen at the end of ''Apocalypse'', is revealed in the novelization of ''Extinction'': [[spoiler:Dr. Isaacs uses Umbrella's cybernetic control over Alice to force her into bringing Angela to him. He reveals that Angela's blood is of no use to him--her T-Virus strain is different from the one ravaging the world--and orders Alice to kill Angela. Alice puts a bullet through Angela's head.]][[note]]''The novelization is considered non-canon to the films, though.[[/note]]
* AlternativeForeignThemeSong: The Japanese version of ''Extinction'' uses [[http://www.youtube.com/watch?v=2CchbmYkyGE "Last Angel"]] by Koda Kumi as the theme song.
* AssholeVictim: No one sheds a tear when Alice gets the rednecks torn apart by their own zombie dogs.
* ApocalypseHow: Class 5, in progress.
* AttemptedRape: Some post-apocalyptic rednecks set up a fake DistressCall which ensnares Alice. They looked as though they were about to rape her until she {{neck snap}}s one of them and they decide to feed her to the dogs.
* AudibleSharpness: Alice's knives.
* BadassLongcoat: Alice rocks a particular awesome one throughout the film.
* BigDamnHeroes: Alice gets one when she shows up and uses her psychic powers to kill off the [[GoddamnedBats crows]] attacking the convoy.
* BlackDudeDiesFirst: Betty is first female survivor to die, while LJ is the first male survivor to die.
* BondOneLiner: When Isaacs gets sliced to pieces by the laser grid, the Alice clone says, "Yeah, you're the future, all right."
* CharacterDevelopment: It may just be five years of surviving a ZombieApocalypse, but [[EthnicScrappy LJ]] seems like a lot less of a "gangsta" and seems to take things more seriously.
* CloningBlues: [[spoiler:Guess what, Alice? You just got a whole army of... yourself.]] Oddly enough, [[spoiler:one of them wakes up just in time to save the real Alice from the laser trap.]]
* DeathByAdaptation: [[spoiler:Carlos survives the events of ''Resident Evil 3''. He dies in this movie.]]
* DeathByIrony: Dr. Isaacs spends all his time killing Alice clones and experimenting with the anti-virus. In the end, he gets killed by Alice clones and the anti-virus.
* DualWielding: Alice's paired kukri knives.
* DwindlingParty
* DyingMomentOfAwesome: [[spoiler:Carlos blowing up a truck to [[TakingYouWithMe take a whole bunch of zombies down with him]] while doing a J.]]
* EliteMooks: Dr. Isaacs' enhanced zombies are faster, stronger, and supposedly smarter than the regular variety.
* {{Expositron 9000}}: The White Queen.
* GunsAkimbo: Alice wields pretty much all her guns this way. Unlike the prior film in the series, Carlos and LJ seem content to just use one gun.
* HeelFaceTurn: The White Queen technically undergoes one of these. It just barely qualifies as her programming was designed to prevent the spread of the T-virus and try to control the epidemic as best she could. As an AI, she has no loyalty to Umbrella beyond what is programmed into her. Since Umbrella didn't think to do this, she turns on them as she quickly concludes that Umbrella is only going to make the outbreak worse if allowed to continue existing.
* HeroicBSOD: Alice, though this is a result of Umbrella's mind control.
* HallOfMirrors: LJ ends up shooting at a zombie's reflection. The zombie was actually ''[[OhCrap behind him]]''.
* {{Hologram}}: This is how the heads of Umbrella meet. Alice uses it at the end of the third movie as well.
* HeroicHost: Alice and the T-virus.
* IdiotBall: LJ deciding to hide his infection and put everyone in danger, despite being competent enough to survive for five years in a zombie apocalypse.
* ItCanThink: After being injected with a serum from Alice's blood by Isaacs, some of the zombies regain the ability to remember and think, as one zombie remembers how to use a camera and a cell phone.
* MesACrowd: The third film introduces many Alices. The fourth film [[spoiler:promptly disposes of them all.]]
* NeverTrustATrailer: The trailer for ''Extinction'' started out with a [[http://www.youtube.com/watch?v=PHP0euSxWlQ commercial]] for UsefulNotes/LasVegas.
* NewPowersAsThePlotDemands: The T-virus, a virus that turns humans and animals into zombies, can now somehow also cause a severe enough global drought to dry out the oceans. It is notable that the drought was {{retcon}}ned out of the subsequent films.
* PsychicPowers: Alice gets these from the T-virus.
* PsychicNosebleed: Alice.
* QuestForIdentity: Alice has shades of this.
* RagnarokProofing: Not perfect, but the film does show what a years worth of post-apocalypse decay can do.
* RaisingTheSteaks: The crows.
* RoomFullOfZombies: The ClownCar trailer full of zombies.
* ScarfOfAsskicking: Alice's badass scarf which she wears with her equally badass duster jacket.
* SequelHook: [[spoiler:It ends with Alice finding the rest of the clones of her that Umbrella was using for their experiments... and they're waking up.]]
* SyntheticPlague: The release of the T-virus in ''[[Film/ResidentEvilApocalypse Apocalypse]]'' caused mass death by the time of ''Extinction''.
* VivaLasVegas: The crew stop off here.
* ZombieApocalypse
* ZombieGait: Averted, subverted, inverted, played straight, played for laughs and everywhere inbetween.
