'''''The Descent''''' is a 2005 British horror film written and directed by Neil Marshall, director of ''Film/DogSoldiers'' and ''Film/{{Doomsday}}''. The film follows a group of six women who embark on a caving expedition and become trapped underground after a cave-in. Things go from bad to worse when they discover that the cave is home to predatory, [[TheMorlocks pale humanoid creatures]] (known as "Crawlers"). As the Crawlers hunt them down, the women embark on a struggle to survive and escape the cave - but that's not their only problem, as the friends' trust in each other slowly begins to deteriorate in the tense, claustrophobic environment. A sequel, ''The Descent Part 2'', was released in December 2009.

Has nothing to do with the video game series ''{{Descent}}''. Nor the novel ''Literature/TheDescent'' by Jeff Long, although there are certainly similarities.

[[DuelingMovies Was released almost simultaneously with two nigh-identical films]]; ''Film/TheCave'' and ''Film/TheCavern''.

-----
!!The original film provides examples of:

* AbandonedHospitalAwakening: Subverted, when Sarah ''seems'' to wake up in an AbandonedHospital after the car accident. After about twenty seconds, it turns out to be a hallucination, she's in a normal hospital.
* AccidentalMurder: [[spoiler:Juno mortally wounds Beth after mistaking her for a Crawler.]]
* ActionGirl: Pretty much the entire group, with the possible exception of [[spoiler:Holly and Beth]], who are killed before they have the chance to kick some ass.
* AnkleDrag: Happens to [[spoiler:Becca]] as she's taken away by a Crawler.
* ArcWords: [[spoiler:"Love each day."]]
* AxCrazy: [[spoiler:Sarah]], eventually.
* {{Badass}}: Almost everyone has their moments, but Juno and [[spoiler:Sarah]] especially apply for this trope.
* TheBechdelTest: With a cast of almost only women, there is almost no mention of men or their love lives except for an offhand reference by Sam of her boyfriend, and [[spoiler: Sarah finding out Juno was having an affair with her late-husband.]]
* BetterToDieThanBeKilled: [[spoiler:Beth [[ICannotSelfTerminate begs Sarah to kill her]], rather than leave her to die slowly from her neck wound, or end up as food for the Crawlers.]]
* BewareTheNiceOnes: [[spoiler:Sarah]].
* [[BigBrotherInstinct Big Sister Instinct]]: Becca is very caring and protective towards her sweet little sister Sam, and to a lesser extent, the rest of the less-experienced caving group. Also, it's fairly subtle, but Beth displays [[BigBrotherInstinct Big Sister Instincts]] towards anyone in the group who needs it - she's constantly looking after the emotionally fragile (due to the death of her husband and child) Sarah, she gives her jacket to Holly after she breaks her leg and helps her stand and walk (along with [[TheMedic Sam]]) and she goes back to help Juno in the crawler fight.
* BreakTheCutie: Losing her family in a car accident does this to Sarah. [[spoiler:Then the events in the cave break her some more.]]
* CaliforniaDoubling: Set in America (aside from the beginning of the movie), filmed in England and Scotland.
* CannibalLarder: Sarah falls into a blood-filled pit with gnawed human and animal bones scattered around it.
* CatapultNightmare: Sarah in the cabin.
* CerebusCallBack: The group picture the group takes of themselves the morning of the caving trip shows up at the end with the credits rolling over it.
* ChekhovsGun:
** [[spoiler:Juno's necklace]]. Also, [[spoiler: Sam's watch]].
** Also the climbing picks. In RealLife, those are only used to climb frozen waterfalls, but they're necessary to the movie as weapons.
** Averted, however, with the massive drill that Becca has attached to her belt (most prominently seen during the scene where she crosses the crevasse). This is pointed out in the director and cast commentary.
* ChekhovsSkill: A rather odd aversion. Extreme-sports expert Becca is able, with a great amount of difficulty, to climb across the roof of a cavern using a long rope and several [[http://en.wikipedia.org/wiki/Carabiner carabiners.]] This is set-up for later when the much less experienced Sam has to do it with about three feet of rope, one carabiner, and no gloves to protect her hands. Realistically, she can't, [[spoiler:and then a crawler comes.]]
** Also, the impending graduation of Sam from medical school while the women are at the cabins came in handy in two major situations.
* {{Claustrophobia}}: Not present in any of the main characters, but the scene where the group is squeezing through an ''extremely'' tight tunnel - not to mention the fact that Sarah gets stuck in it - can invoke this in viewers.
* CoversAlwaysLie: One version of the cover is a fan servicey pose of all girls forming a skull while wearing tight revealing outfits, (an ode to Creator/SalvadorDali's Skull Women.) Most of the characters were wandering in the dark covered in blood and wearing full protective gear, anyone expecting hawtness to occur would be mildly disappointed.
** One of the promotional images shows all the characters sans helmets and wearing sleeveless tops. In actuality, not everyone loses their helmets (Sam keeps hers on all the time), and Sarah and Beth are the only characters to strip down to their vest tops.
* CreepyChild: Sarah's constant hallucinations of Jessica arguably qualify.
* CruelAndUnusualDeath: Poor [[spoiler:Becca]] arguably recieves the slowest, most painful death in the film - a Crawler rips open her stomach and starts devouring her innards while she is still alive. ''Ouch''.
* CruelTwistEnding: [[spoiler:The UK Ending. Sarah merely hallucinated escaping the cave; there is no exit. All along the characters have only been descending further down, without any way out. Waking up right where she lost consciousness, Sarah goes on to imagine her dead daughter sitting in front of her with a birthday cake, as the crawlers are homing in on Sarah to eat her alive.]]
* CynicismCatalyst: Sarah becomes depressed and withdrawn after losing her husband and daughter in a car accident. [[spoiler: The fact that she's already emotionally fragile may have contributed to her later [[AxCrazy axe-craziness]].]]
* DangerTakesABackseat: Sort of. More like [[DangerTakesABackseat Danger Takes A Passenger Seat]]. [[spoiler:(Although this moment turns out to be one of Sarah's hallucinations.)]]
* DeathByPragmatism: Justified with [[spoiler:Juno.]] She was [[spoiler:murdered]] after she accidentally [[spoiler:fatally wounded Beth]] and then ran away. Sarah found out, but she ''didn't'' know it was an accident...
* DevelopingDoomedCharacters: Pulled off successfully. The crawlers don't arrive until halfway through the film, but most critics appreciated that because the time was spent character building and establishing the decaying trust within the group and sense of claustrophobia. Some even complained that the crawlers showed up at all to interrupt the caving drama.
* DownerEnding:
** The original UK ending: [[spoiler:Everyone dies. Sarah cripples Juno and leaves her for the crawlers, then [[HopeSpot imagines escaping]]. [[CruelTwistEnding She wakes up]], hallucinates that her daughter is there, and gives up to stay with the hallucination.]]
** The US ending: [[spoiler:After injuring Juno, Sarah really does escape, and hallucinates Juno's creepy looking ghost is there with her. She's an AxCrazy murderer, her family and friends are all dead, and there are still strong implications that she's just imagining this and is still in the cave.]] Considering they changed the ending because it was too bleak, there isn't that much of a difference.
* DramaticNecklaceRemoval: Happens after [[spoiler:Juno accidentally pickaxes Beth through the throat]] - as she collapses, [[spoiler:Beth]] rips [[spoiler:Juno]]'s necklace from her.
* DyingMomentOfAwesome: [[spoiler:Sam gets her throat slashed by a Crawler]]. Just before she dies, however, she gets a sudden burst of adrenaline and stabs the Crawler, causing it to plummet into the crevasse below. [[spoiler:As it turns out, there was water below and the Crawler doesn't actually die at that point (Juno finishes the job), but it still counts as a seriously {{Badass}} moment for Sam]].
* DwindlingParty
* EyeScream: Between this and ''Film/TwentyEightDaysLater'', killing an enemy by pushing its eyes in with your thumbs has apparently become the British horror symbol for "I've turned [[spoiler:psychopathic and metaphorically become one of the monsters."]]
** Earlier, [[spoiler: Sarah]] takes out the female Crawler by stabbing her in the eye with an animal horn.
* FaceRevealingTurn: One of Sarah's nightmares has her daughter being seen from behind, who suddenly turns around to reveal the face of a Crawler.
* FanDisservice: Sarah spends a good deal of the last part of the film in her tight vest top after shedding her other layers, and covered in sweat. She also happens to be covered in blood from head to foot. (Others may see this as FanService, if you're into that kind of thing...)
* FinalGirl: Until the sequel changed the canon, Sarah [[spoiler:made herself into the FinalGirl. And then died, as a consequence of not having Juno around to help her, snap her out of her crazy hallucinating reverie, or rage-fuel her badassery and survival instincts. Oops.]]
* {{Fingore}}: It's hard to make out, but, when [[spoiler:Becca]] is being dragged to her death, her fingernails scrape across the ground, ripping off at least one of them in the process.
* {{Foreshadowing}}: Before they enter the cave, Becca reels off a list of things commonly experienced by cavers, such as hallucinations and claustrophobia, among others. Most, if not all of these things happen down there.
** It's shown that Sarah is taking some form of (prescribed) psychiatric medication in a blink-and-you-miss-it scene at the cabin... none of which she takes with her due to Juno's lie about the difficulty of the cave system, thinking that it'd be a day trip.
** [[spoiler:Juno and Paul's affair]] is heavily foreshadowed several times before it's revealed:
*** The opening has Paul [[spoiler:helping Juno with her helmet and sharing a few tender looks with her.]] His distraction in the car can also be put down to his troubled thoughts on the matter.
*** Juno has a necklace that she plays with at one point and later kisses for luck before crossing the crevasse. [[spoiler:It turns out Paul gave it to her as a gift.]]
*** In the cabin, Sarah quotes Paul's personal motto. [[spoiler:This causes Juno to give her a look. Juno's aforementioned necklace has said motto engraved on it.]]
*** "We ''all'' lost something in that crash."
** See also ShownTheirWork / ViewersAreGeniuses below.
* FreakOut:
** Happens to [[spoiler:Sarah]] ''twice'': first time is when [[spoiler: she loses her husband and daughter in a horrific car accident one year prior to the caving trip]], and the second is when she [[AxCrazy completely snaps]] after being attacked by the Crawlers, being forced to watch said Crawlers partially devour the corpse of [[spoiler:Holly]] directly in front of her, and then granting [[spoiler:Beth's]] ICannotSelfTerminate request by [[spoiler:bashing her head in with a rock]]. Then there's the small fact that she mistakenly believes that [[spoiler:Juno deliberately stabbed Beth through the throat]]. The result of all this, combined with her first FreakOut, is not pretty.
** Following Sarah's claims ([[CassandraTruth initially dismissed as hallucinations by the rest of the group]]) that she saw "a man", Becca has a smaller-scale FreakOut when the team stumbles across [[spoiler:the Crawlers' feeding ground]], declaring "Oh, '''fuck it!'''" and hysterically screaming out for help on the off-chance that someone else may be down there to help them.
* FreezeFrameBonus:
** One of the first sightings of a Crawler is [[spoiler: right after the tunnel collapse, on a ledge when Sarah is sweeping the cave with her flashlight.]] It's visible for barely one second.
** The ''very first'' sighting of a Crawler can be seen very, very briefly in the scene where [[spoiler:Juno lights up a flare for the first time and throws it into the middle of the cave]]. It is very difficult to spot without pausing and looking closely. According to [[WordOfGod Neil Marshall]], this is actually a continuity error - the Crawler is one of the film crew. When this mistake was spotted, rather than remove it digitally, [[ThrowItIn the crewmember's face was deliberately whitened to bring it out more]], thus making him look like a hiding Crawler.
*** In the same scene, a Crawler can be seen [[spoiler: to the left-hand side of the screen when Sarah is looking around]] for a few seconds.
* FreudWasRight: As is jokingly (or perhaps not) stated in the director and cast commentary on the DVD, several people have believed that this movie is all about sex, what with the little white men chasing sweaty women down dripping wet tunnels...
** Invoked by Neil Marshall on the DVD "Beneath the Scenes", where multiple jokes are made about how similar a piece of the cave is to a certain part of the female anatomy. To wit - "Sometimes a cigar is just a cigar!"
* GenreShift: From PrimalFear to SlasherMovie.
* {{Gorn}}: It's not excessive, but is definitely present in a few scenes.
* GoryDiscretionShot: [[spoiler:Happens when Paul and Jessica are killed. We see a pole emerge from the back of Paul's headrest complete with blood splatter, and Jessica's death isn't shown at all - the only indication of her death is her blood seeping out from under the car.]]
** Later, when [[spoiler:Sarah puts Beth out of her misery by smashing her head with a rock]], the camera angle and the darkness prevent the viewer from getting a clear look at the event. Seeing the full result would have probably killed one of the saddest moments in the film.
** The death of the child Crawler.
* GroinAttack: Towards the end, Juno repeatedly knees the Crawler she's grappling with in the crotch.
* HeroicBSOD: A deleted scene has Becca go through this after [[spoiler: seeing her sister get killed by a crawler]], desperately shrieking out that every step further down these caves is another step closer to hell.
* HotTeacher: Beth, the English teacher, who also manages to use her knowledge to recognize cave paintings.
* AHouseDivided: The whole group is somewhat mad at Juno for lying to them and bringing them down to an unexplored cave that was much more dangerous than they were expecting. However, it's water under the bridge once they meet the crawlers. That is, until Sarah [[spoiler:finds out what Juno did to Beth, and she doesn't know it was an accident, plus a recent discovery of Juno's extracurricular activities with her husband, and she's also feeling a bit AxCrazy... The result is not pretty.]]
* HowlOfSorrow: [[spoiler:Sarah]], after she has well and truly [[HeroicBSOD lost it]].
* ICannotSelfTerminate: [[spoiler:Beth, after being accidentally stabbed through the throat by Juno, begs Sarah to kill her, lest she die slowly and painfully or be ripped apart by the Crawlers.]]
* IdiotBall: Subverted. Almost every named character makes at least one mistake leading to their own death or someone else's. Usually, it's only one mistake, and it's pretty believable given circumstances. The only named character who doesn't do this is [[spoiler: Jessica, Sarah's daughter]].
* ImAHumanitarian: [[spoiler:The Crawlers could technically be considered cannibals, as they are, according to [[WordOfGod Neil Marshall]], evolved cavemen]]. There are several hints of this throughout the film.
* ImpaledWithExtremePrejudice: [[spoiler:Both Paul and Jessica get this courtesy of some poorly-tied-down metal poles at the beginning of the movie. Later, Sarah has a nightmare in which a metal pole suddenly flies through the cabin window and through her head.]]
* InfantImmortality: Averted in Jessica's case. The death of the child Crawler may also count.
* JumpScare:
** Starting with the bats and going on from there.
** There's an even earlier one when Sarah has her nightmare in the cabin.
* TheKillerInMe: [[spoiler:See ThroughTheEyesOfMadness below for details.]]
* KillTheCutie: [[spoiler:Sam]].
* KillEmAll:
** [[spoiler:Everyone who gets a speaking part dies, two of them within the first five minutes. To be fair, there are only eight people in the whole cast. Playing humans, at least.]]
** That is, until the sequel changed this. [[spoiler:Sarah gets it together enough to stagger out of an entrance to the cave, albeit with amnesia about the last two days.]]
* LeftForDead: [[spoiler:Beth]] and [[spoiler:Juno]].
* LetsSplitUpGang: Subverted, as it's not intentional and done in a moment of panic. [[spoiler: Later averted, as everyone gets back together at some point, though not all at once.]]
* MamaBear: The first female Crawler seen in the film appears shortly after Sarah kills the Crawler's child. Upon learning that her child is dead (after a surprisingly sad moment of the Crawler desperately and pitifully nudging the body), she immediately goes berserk.
* ManBitesMan: It's a bit hard to make out due to the lighting, but, during the climactic fight sequence, [[spoiler:Sarah]] bites off a Crawler's ear and doesn't spit it out until she's finished fighting.
* MatchlightDangerRevelation: It is only when [[spoiler:the night vision on Holly's camcorder is switched on]] that a Crawler is seen up close for the first time.
* TheMedic: Sam, who is a med student. Because of this, she can help treat injuries the best she can, and also examine the crawler's biology and try to recognize how they function.
* MercyKill: [[spoiler:Sarah reluctantly performs one on Beth at the latter's [[ICannotSelfTerminate insistence]].]]
* TheMistress: [[spoiler: Juno]] is deeply implied to have been having an affair with Sarah's husband. When [[spoiler:Beth handed Sarah Juno's necklace]] she whispers that is was from him, as it has his personal motto engraved in it.
* MoodWhiplash: The opening. It goes from Sarah, Juno and Beth white water rafting and having a great time, to less uplifting when Sarah wondering why her husband is acting oddly, to downright horrific when the car crash happens.
* MookHorrorShow: By the end the women have become so desperate and hateful of the Crawlers that they start ripping them apart with even more viciousness than the Crawlers themselves ever showed. You almost feel sorry for the little freaks.
* {{Morlocks}}: The crawlers. Morlock creator H.G. Wells is one of Neil Marshall's favorite writers.
* MsFanservice: Juno spends most of the film in a tight red climbing top, unzipped to reveal a hint of cleavage, and still looks hot when covered in sweat, dirt and blood. Being played by Natalie Mendoza helps.
* NeckSnap: Juno does this to a Crawler.
* NightmareSequence: Sarah has a lot of them.
* NotQuiteDead: [[spoiler:Beth.]]
* NotSoDifferent: [[spoiler:Sarah's brutality and extremely savage fighting towards the end is symbolic of how she's becoming more like the Crawlers.]]
* NothingExcitingEverHappensHere: Holly is annoyed that Juno is taking them to Borham Caverns, a cave system for tourists, as she believes it will be boring. It later turns out that [[spoiler:Juno deliberately led them to an unknown cave system instead]].
* NothingIsScarier:
** For some of the jump scares, it's fairly easy to tell that something bad is going happen soon. We don't know what, where or exactly when, so being somewhat forewarned only makes it that much more frightening.
** For the first 2/3 of the film, pretty much ''nothing does happen'', instead relying on the atmosphere of the cave itself to create the sense of dread. For this reason, many find this actually ''scarier'' than the Crawlers.
* OhCrap:
** The facial expression isn't seen, but the tone of voice says it all: "Dead animals! ''Hundreds'' of them!"
** Earlier, there's the looks on Sarah and Beth's faces when [[spoiler:the cave tunnel starts to collapse]].
--> '''Beth:''' Okay, fuck the rope bag. ''Move! Move! MOVE!!''
* PuppyDogEyes: Holly achieves this shortly before [[spoiler:she falls down a pit and breaks her leg.]]
* RedemptionEqualsDeath
* RockBottom: After Sarah gets stuck in a tight passage, Beth tries to calm her down, saying that the worst thing that has happened to Sarah has already happened, and generally implies that nothing bad is going to happen again. They are wrong.
* RuleOfSymbolism: When [[spoiler:Sarah]] unleashes her HowlOfSorrow, the action cuts back to Juno, Becca and Sam, who hear a Crawler scream. The sounds are edited so it sounds as though [[spoiler:Sarah's]] scream has suddenly changed into that of one of the Crawlers'. Later (in the original UK ending), [[spoiler:Sarah]] rises from the floor of the cave in a manner ''very'' reminiscent of the way a Crawler would move.
* SceneryPorn:
** The shots of the river during the prologue, the shots of the Appalachian Mountains, and the first cave chamber.
** SceneryGorn: The Crawlers' chambers.
* ShooOutTheClowns: The first of the group to go is [[spoiler: Holly, the crazy awesome chick.]]
* ShoutOut:
** "[[ImADoctorNotAPlaceholder I'm an English teacher]], not fucking Franchise/TombRaider."
** The music in the scene where Juno and Sarah move through the caverns by flare light bears unmistakable resemblance to Morricone's theme from ''Film/TheThing1982''.
** The scene where the team climbs the rockface into the feeding chamber is an almost shot for shot replication of the scene in ''Film/{{Alien}}'' where Lambert and Kane climb up to meet the Space Jockey.
** The overhead shot of Beth and Sarah driving to the cabin is a visual reference to the film version of ''Film/TheShining''.
** There are many subtle references to ''Film/{{Deliverance}}'' peppered throughout the film, such as the rafting scene, Juno's red suit, and others.
** A possible (and less gruesome) ShoutOut to Neil Marshall's previous film, ''Film/DogSoldiers'', occurs when Sam has to push [[spoiler:Holly's]] splintered bone back into her leg - in ''Film/DogSoldiers'', Cooper has to push Wells' intestines back into him.
** Another, very subtle, ''Film/DogSoldiers'' reference, doubling as a MythologyGag: When Sarah discovers an old helmet in the cave, a closer look reveals the name "Oswald" written on the brim. This is a reference to Eddie Oswald, the character mentioned by Wells in ''Film/DogSoldiers''. Neil Marshall has mentioned that he plans to reference Eddie Oswald in all of his films.
* ShownTheirWork / ViewersAreGeniuses: Extremely subtle cues exist to foreshadow plot points.
** [[spoiler: The first crawlspace is clearly limestone, notoriously treacherous for cave-ins if not reinforced by more stable minerals. Given the close proximity to a riverbed, it's not unreasonable to assume it's just a thin coating... in a level 2 cave.]]
** The Crawlers have the auditory ShoutOut to the ''Franchise/{{Predator}}'' series. [[spoiler: They're similar to the clicks dolphins make, and are a very early tip-off that they use sonar.]]
** Also noteworthy how no one stops to [[AsYouKnow exposit on]] how various caving techniques work, e.g. the use of a lighter to find air currents.
* SickeningCrunch: Occurs when [[spoiler:Holly]] breaks her leg.
* TeamMom: While Juno leads the group, it's Becca who reassures them and makes sure they're doing everything safely.
* TearsOfBlood: Near the end of the film, [[spoiler:when Sarah hallucinates the presence of Juno's ghost, the latter has blood seeping from her eyes]].
* ThroughTheEyesOfMadness: [[spoiler:Since Sarah was hallucinating without a doubt at several separate points, there is a popular theory that the cave monsters were all in her mind and [[TheKillerInMe it was her that killed all her friends]]. The director originally put a crawler silhouette into the first hallucination sequence (which took place outside the cave) but had it edited out because he wanted to leave it more ambiguous.]]
* TooDumbToLive:
** [[spoiler:Beth]] walks very slowly up to within arm's reach of an ice-pick wielding [[spoiler:Juno]], and chooses never to say or do anything to announce her presence. [[spoiler:Juno mistakes her for a crawler and puts the pick through her neck.]]
** [[spoiler:Holly.]] Yes, run ahead of your fellow spelunkers in an unknown cave system! And you're surprised you fell in a hole?!
** TropesAreNotBad, however, and [[spoiler:Beth]] was very likely either in shock or trying to avoid drawing the attention of the Crawlers, while [[spoiler:Holly]] was already well-established as a reckless sort.
* TookALevelInBadass: [[spoiler:Sarah]], after the events in the cave cause her to snap.
* VasquezAlwaysDies: [[spoiler:Holly. Though as everybody dies, it's more like Vasquez dies first.]]
* VomitIndiscretionShot: Happens towards the end when [[spoiler:Sarah unwinds the car window to vomit on the road.]]
* WeHardlyKnewYe: Paul and Jessica.
* WhatCouldPossiblyGoWrong: The RockBottom example above, and also Juno's comment about how the women needn't worry about getting lost because she (Juno) has "never been lost in (her) life".
* XMeetsY: ''[[Literature/TheDescent Jeff Long's The Descent]]'' Meets ''[[Creator/HPLovecraft Lurking Fear]]''

-----
!!The sequel provides examples of:

* ActionSurvivor: When Sarah sees Dan and Rios being stalked unawares by a Crawler, she doesn't attack the Crawler or try to shout out a warning. Rather, she [[spoiler:tackles Rios and keeps her from making a sound while the Crawler attacks and kills Dan, then stealthily grabs Greg's supplies off of his body while the Crawler drags his corpse away.]]
* AssholeVictim: [[spoiler: Sheriff Vaines]]
* BadassGrandpa: Sheriff Vaines gets a jump scare with a Crawler leaping out screaming. His reaction? Punch it in the face and knock it down.
* CallBack: [[spoiler:Rios']] escape is nearly a shot-for-shot remake of the first movie's ending.
* ChainedHeat: Vaines chains himself to Sarah partway through the movie to keep her from running away.
* CoversAlwaysLie: Not so much the cover, but the blurb, which promises "a new tribe of crawlers, inbred, deformed and even more viciously feral". Nope, same old Crawlers as the first movie.
* CruelTwistEnding: See ShockingSwerve.
* DownerEnding: [[spoiler: KillEmAll, much like the original.]]
* FinalGirl: Elen
* HeroicSacrifice: [[spoiler: Sarah, she starts screaming to protect Elen from crawlers and gets eaten by them]]
* HollywoodDarkness: The sequel forgoes pitch-blackness for silhouette shots in most cases
* NeverFoundTheBody: Exploited to [[strike:not]] explain [[spoiler:Juno's]] survival after the events of the first movie.
* NotQuiteDead: Much like Beth in the first movie, [[spoiler:Greg]] proves to be not quite dead when he grabs [[spoiler:Juno]] on their way out.
* RedemptionEqualsDeath: [[spoiler:Sarah and Juno]] have learned from each other that the easiest way to survive is to make sure that the others die. By the end of the film, they've both executed self-sacrifices to allow others to live.
* RevisedEnding: Based on the [[DVDCommentary Director's Commentary]] and an [[http://hubpages.com/hub/THE-DESCENT-2-coverage early script review]], the ending may have originally lacked its current ShockingSwerve. If so, it was definitely a failed AuthorsSavingThrow.
* SenselessSacrifice: [[spoiler:Greg]] tackles one of the Crawlers into a chasm to give [[spoiler:Cath]] a chance to get to the other side whereupon she's killed by a Crawler on the other side. Admittedly, he was probably dying at the time due to having had the side of his neck torn out.
* ThisIsADrill: Greg uses a power drill in his kit to kill one of the crawlers by drilling into its head.
* TookALevelInBadass: Once she recovers her memory, Sarah regains all of her levels in Badass. [[spoiler:Juno]] isn't far behind.
* VasquezAlwaysDies: [[spoiler:Juno and Sarah.]]
* WildChild: [[spoiler:Juno]] initially seems to have reverted to this in her survival. She gets better.
