->''"It seems every year I'm at camp someone loses their head."''
-->-- '''Angela'''

'''''Sleepaway Camp III: Teenage Wasteland''''' is a SlasherMovie released in 1989. Shot back-to-back with [[Film/SleepawayCampIIUnhappyCampers its predecessor]], it follows Angela infiltrating a group of campers to continue to exact her brand of "niceness".

[[Film/SleepawayCampIVTheSurvivor Another sequel]] was made... but not without problems.

!!This film has the examples of:

* AdultsAreUseless: Herman and Lily Miranda, who are the adults in charge of the camp, don't even notice that their campers (and each other) are rapidly disappearing, but this can be partly chalked up to the fact that they'd been split into three teams and separated from one another. Still, the uselessness of the two is a big reason why they die.
** Averted by Barney Whitmore, a genuinely nice guy who cares for the campers.
* AffablyEvil: Angela's surprisingly kinder in this film and only kills a lot of people who actually deserve to die. Otherwise, she's reluctant to kill people who caused her no harm unless forced to.
* AllWomenAreLustful:
** Arab actually jokes about sex between the campers and makes fun of how Angela is the only girl to wear a bra.
** Jan enjoys Herman's proposition for sex despite the fact that he's a DirtyOldMan and she's underage.
* AlphaBitch: Cindy
* AssholeVictim: Pretty much everyone who dies except Barney, Greg and Anita. Arab may also be an exception, since the only bad thing she did was curse. Maria may also be exempt due to her never doing anything horrible other than fight with her neglectful parents.
* BigBadWannabe: Riff comes across as this. He acts like he's the bad boy of the campground thanks to his gangster persona, but he naturally gets killed by Angela.
* BikerBabe: Arab comes across as this due to her black leather, casual swearing, and role as a FanserviceExtra.
* BrokenBird:
** Angela comes across as this as she only ever wanted to have a happy summer camp experience, only to have it completely ruined by history repeating itself.
** Maria may come across as one as well due to her troubled home life causing her great depression, her attempts to attend summer camp to overcome her problems, and the fact that she was so cruelly murdered by Angela because the killer needed to steal her identity.
* TheBully: Riff, Snowboy, and Peter stupidly pick on Angela all the time.
* BullyingADragon: ''Everyone'' who interacts with Angela loves to pick on her. This naturally ends with gruesome results for them.
* BusCrash: [[spoiler: Molly didn't survive at the end of the second film.]]
* CarFu: Angel drives over Maria with a garbage truck, and then proceeds to hide and crush her body in its compactor.
* CarryABigStick: Angela interrupts Jan and Herman having sex in a tent, and starts beating and stabbing them with a stick. Snowboy gets the same treatment later.
* CoolOldGuy: Barney Whitmore. While Herman is busy fooling around with a teenage camper and Lily is busy asking the kids to catch their own food (fish) so she can spend more time lazing around, Barney offers the kids hot dogs and bonds with them, [[spoiler:mainly because he didn't have much time to do so with his late son, Sean, from the second movie.]]
* CruelAndUnusualDeath: Angela kills Lily by burying her up the neck and lifting a running lawnmower up and slammed it down on her head.
* DeadPersonImpersonation: Angela steals Maria's identity to infiltrate the New Horizons Camp.
* DeathByRacism: Cindy. She's the most foul-mouthed, racist, xenophobe there ever was and is rewarded with a brutal death.
* DeathBySex: Herman and one of the female campers her screws around with naturally get killed by Angela.
* DecoyProtagonist: The opening makes it seem that we'll be following Maria, but then Angela kills her.
* DirtyOldMan: Herman. He cheats on his wife with an underage teenager.
* DisneyVillainDeath: Technically, Cindy dies thanks to Angela utilizing gravity. Cindy gets suspended by a flagpole, then dropped to her death.
* DownerBeginning: Admittedly, the beginning seems rather sad for Maria. She's a troubled teenage girl with a strained relationship with her family and wants to go to summer camp to turn her life around. Sadly, she ends up killed by Angela so the killer can impersonate her.
* EyeScream: A cop who's looking over Angela in the ambulance gets a syringe in the eye.
* FantasticRacism: Cindy. This line of dialogue should sum it up.
--> '''(Regarding [[NiceGuy Tony]])'''
--> '''Marcia:''' Isn't he cute?
--> '''Cindy:''' [[KickTheDog He's Mexican!]]
* FauxActionGuy: Barney Whitmore is a trained police officer who vows to kill Angela, but suffers a rather anticlimactic death by getting shot dead.
* FinalGirl: Averted with Marcia, who isn't the sole survivor. She isn't as wholesome as she appears either, [[spoiler:as she reveals to her supposed LoveInterest Tony that she "kinda" has a boyfriend already]].
* FishingForSole: Angela manages to fish out a hockey mask from the water. Right afterward it's remarked that the date is [[Franchise/FridayThe13th Saturday the 14th]].
* FlatCharacter: Campers Anita and Greg get no character development throughout the film and their only purpose seems to be filler roles. This is also the reason Angela kills them.
* GainaxEnding: The story closes out with Angela killing two medics before spouting a one liner as she's taken to the hospital.
* HateSink: 90% of the cast is made up of nothing but the worst kind of people in society. In fact, Angela looks like a ''hero'' in comparison.
* HeroicWannabe: More than a few characters have actually deluded themselves into believing that they're decent human beings.
** Bobby is a privileged jock who wants to become a politician someday and tries to cheer up the campers on his team, but he's really a horndog who wants to bone Angela.
** Cindy is a rich girl who thinks that she's the popular funny girl making camp fun when she's just a hypocritical, racist RichBitch.
** Camp Councilor Lily thinks that she's the TeamMom who'll inspire her campers to have fun, but she's just a short-sighted, hypocritical lazy slacker who couldn't care less about what her campers do.
* HorribleJudgeOfCharacter: The entire camp assumes that Angela is a ShrinkingViolet who's easy to bully because she's too timid to fight back. [[SerialKiller If only]] [[NotSoHarmlessVillain they knew...]]
* {{Hypocrite}}: Camp councilor Lily is a lazy, useless, egotistical old woman who wants to be the BigGood of the summer camp, but she's nothing more than FatBitch.
* ImpaledWithExtremePrejudice:
** Herman gets stabbed through the mouth with a stick.
** Greg and Anita get impaled on axes.
* {{Jerkass}}:
** Gangbanger Riff, pranksters Snowboy and Peter, sarcastic biker girl Arab, sex kitten Jan, privileged jingoistic snob Bobby, racist Cindy.
** Averted by Greg and Anita, even Angela says that they're nice kids. She still kills them anyway, only because she considers them boring.
** Also averted by Marcia and Tony, [[spoiler:the sole survivors of the massacre.]]
* KarmicDeath:
** Peter is killed by his own fireworks that he used to scare Angela earlier. She stuffs one into his nose as he sleeps, and lits fuse.
** Lily, who sat on her ass and did nothing all summer while forcing Angela to take out her own garbage and completely covered up the murders that went on around the camp, ends up buried alive by said serial killer she neglected in her own garbage and horrifically murdered.
* KickTheSonOfABitch: Angela brutally murders all the {{jerkass}} characters who spend their time causing mischief and bully others.
* KillAndReplace: Angela murders Maria to steal her identity in order to infiltrate the new summer camp.
* KillTheCutie: Poor BrokenBird Maria ends up killed by Angela right at the beginning.
* NWordPrivileges: Two instances where this is disregarded. One from Riff (a black camper) to Tony (a Latino). Another with Cindy (a white Southern girl) to Riff.
* NiceGuy: Tony. He's a troubled youth, but he really came to camp to get over his bad life.
* NoEnding: The film simply ends abruptly with Angela sitting in the back of an ambulance alive and well.
* NoGoodDeedGoesUnpunished: Angela spares Marcia and Tony's lives, only to have Marcia thank her by stabbing her and leaving her to bleed out.
* NoHoldsBarredBeatdown: Angela beats Jan to death.
* NumberedSequels: With a subtitle.
* OffWithHisHead:
** Angela kicks Arab inside a tent, and chops off her head as she tries to crawls out of it.
** Lily gets her head sliced off by a lawnmower.
* OlderThanTheyLook: A lot of characters lampshade how Angela (who's impersonating Maria) doesn't look like a teenager.
* OnlyKnownByTheirNickname: Snowboy. He never gets referred to as anything else
* ParentalNeglect: Maria is not cherished by her parents at all. Which makes her death all the more tragic.
* PetTheDog: Angela decides to let Marcia and Tony live at the end of the film. This comes back to bite her in the ass when Marcia attacks and (possibly) kills her.
* PoliticallyIncorrectVillain: Cindy is a rich, white girl who harshly criticizes all the ethnic characters in the film.
* ReallyGetsAround: Jan is very eager to sleep with DirtyOldMan Herman.
* RichBitch: Cindy
* ShipperOnDeck: Angela lets Marcia and Tony go because she thinks they look like a nice couple.
* ShoutOut:
** The privileged campers are named after ''Series/TheBradyBunch'' kids, while the less privileged campers are named after characters from ''Theatre/WestSideStory'', including the disguised Angela going incognito "as Maria"
** One of the girls manages to fish up [[Franchise/FridayThe13th a hockey mask from the lake at the summer camp.]]
** Camp owners Herman and Lily Miranda are named after Herman and Lily Munster of ''TheMunsters''.
* SirSwearsALot: Half the cast casually swears like there's no tomorrow.
* SlidingScaleOfComedyAndHorror: Admittedly, the film does a decent job at making you laugh and terrifying you with gruesome murder.
* TheSociopath: Peter and Riff come across as dangerously psychotic. Riff casually threatens to kill others if they piss him off while Peter loves throwing lethal firecrackers at girls for shits and giggles.
* StraightEdgeEvil: Angela does not smoke, drink, or use illegal drugs and if she catches doing any of those things, look out!
* ThoseTwoBadGuys: Snowboy and Peter both pull pranks on Angela all the time. Coincidentally, they both die together as well.
* ThoseTwoGuys: Anita and Greg are usually seen together.
* TitleDrop: Snowboy chants how the summer camp is a "Teenage wasteland."
* TooDumbToLive:
** In the beginning, Maria is being chased down by a semi-truck attempting to run her over. Instead of running towards a crowd of people on the street to call for help, she chooses to run down a dark alley where nobody can see her, unsurprisingly getting killed.
** The newscaster buys drugs off of a minor teenage girl she knows absolutely nothing about and drives into the center of an uninhabited forest to get high, naturally dying of poisonous products.
** The entire camp completely ignores the blood red spray paint across the girl's cabin stating that "Angela is back'' and make absolutely nothing of it until it's too late.
* TokenMinority: Each group of campers has at least one African-American, one Latin American, and one Asian-American. The underprivileged group actually has two African-Americans in Anita and Riff.
* UnwillingSuspension: Angela does this to Cindy by hoisting her up a flagpole. She then lets go of the rope, causing her to die by falling..
* YouKilledMyFather: Turns out Sean from the second movie had a vengeful father (he is not TheHero so he is killed anticlimactically after confronting Angela)
* YourCheatingHeart:
** Herman cheats on his wife with an underage teenage girl.
** [[spoiler: Marcia reveals to her summer love Tony that she already has a boyfriend.]]
* WhatHappenedToTheMouse: Tawny the reporter confirms the Camp Rolling Hills massacre death count at [[spoiler:19, meaning Molly didn't survive the previous movie.]]
* YourHeadASplode: Peter gets his head blown off by one of his own fire crackers.
