The movie starts with the popular girls of Reagan High fake-kidnapping one of their group, Liz Purr (Charlotte Ayanna), as part of her seventeenth birthday, only to find when they arrive that she has choked to death on the jawbreaker candy that they used to gag her. Alpha Bitch Courtney Shayne (McGowan) then leads the others to create an elaborate cover story that would paint Liz's death as an accident resulting from a kinky sexual encounter and get them off scot-free.
One of the girls, Julie Freeman (Gayheart), struggles to come to terms with what they've done and is summarily shunned by Courtney and her lapdog, Marcie Fox (Benz). On top of this, she is replaced by the geeky Fern Mayo (Greer), who Courtney transforms into the glamourous Vylette in return for the girl's silence. But the attention lavished upon "Vylette" soon goes to Fern's head and she begins to encroach on Courtney's position as the Queen Bee, only to discover exactly why that was a bad idea as she is publicly humiliated. Meanwhile, when Julie is given a box of Liz's possessions, she stumbles upon something that will prove to be Courtney's downfall just as she prepares to accept the title of Prom Queen that Liz's death left her free to claim.
Tropes in this film include:
- The '90s: Jawbreaker encapsulates the trends that were popular during the decade, such as fashion, articles and objects, Talk Shows talking about how "the crowd influences on others", the use of Dawson Casting on behalf of the movie's cast, Marilyn Manson having a cameo in the movie...
- Accidental Murder: Liz's cause of death? Choking on a jawbreaker that her friends (specifically, Courtney) used to gag her while fake-kidnapping her. The duct tape didn't help.
- Adults Are Useless: So no principals or teachers have a problem with the girls parking directly in front of the school?
- Asshole Victim: Subverted with Liz, who was a genuinely sweet, friendly girl. However, Courtney does her best to make her seem like this, making up a story for the police about Liz seducing older men and bringing them back home to have sex with.
- Backstabbing the Alpha Bitch: Fern, as Vylette, once when she realizes that she has the power to overshadow Courtney, takes advantage of the attention given to her. That's when Courtney knocks her down a peg.
- Bare Your Midriff: The three main characters (see the film poster above) and most female characters have worn outfits that leave their midsection exposed.
- Because You Were Nice to Me: Fern's liking of Liz was because she was nice to her. Even helping her gather her homework together when Liz's posse knocked it down.
- Casting Gag: Liz's parents are played by William Katt and P.J. Soles, who played Tommy and Norma in Carrie (1976), one of the major inspirations behind this film.
- Chekhov's Gun: The Polaroid camera and Liz's birthday card.
- Class Princess: Liz was described by the narrator as the Princess Di of Reagan High, ruling with kindness, which really pissed off her Alpha Bitch friend, Courtney, and which made her early tragic death all the more awful.
- Deadly Prank: The premise of the film. Courtney and the others were going to surprise Liz for her 17th birthday, while kidnapping her, since the prank has gotten popular with others high schoolers... until the "joke" was on them. Generally, the prank wouldn't have been lethal but Courtney just had to use that jawbreaker without running it by Marcie and Julie first.
- Death by Sex: Courtney tries to set up Liz's death as such. Either to pin her up as being abused or her not being "so innocent and pure as she was thought to be". The catch? It fooled the police. At first, anyway.
- Did Not Think This Through: Courtney never stopped to consider the danger of stuffing a jawbreaker inside Liz's mouth before taping it shut until it was too late. Julie immediately calls out Courtney's stupidity after they learn what's making the lump in Liz's throat.Courtney: It was supposed to be for fun. I just didnt want her to scream I thought a jawbreaker would be funny.
Julie: You gagged her with a jawbreaker?!

- Erotic Eating: Courtney uses it as part of sex play with her boyfriend, using a popsicle. Just to make him mime on what he wants her to do to him.
- Establishing Character Moment: The opening shot of the film is Courtney, Marcie, Julie, and Liz walking down the hallway, while Fern drops some papers in front of them. While the other three walk past without so much as a passing glance, Liz stops to help Fern pick up her things. This establishes her as the Nice Girl of Courtney's Girl Posse, making her death much sadder.
- While Julie doesn't stop to help like Liz, she still steps over Fern's dropped papers rather than walking over them, a subtle hint that while not as nice as Liz, she could still be kinder than Courtney and Marcie.

What have you done, Courtney?! What have you done?
Courtney: It's just what I had to do, dear.
Julie: What? Destroy another life, Courtney?
Courtney: Life's a bitch, then you die.
Julie: No honey, you're the bitch!

- Make Way for the Princess: The entire high school makes way for the breathtaking entrance of the Girl Posse.

- Smoking Is Glamorous: Fern starts to smoke after "becoming" Vylette.
- Shrinking Violet: Fern is your standard shy and quiet girl from High School that is not as beautiful as the Girl Posse and would be unnoticed by the crowd and the rest of her classmates.

And this makes her more confident... and it works pretty well, even with a name such as Vylette.
- Stalker with a Crush: Fern Mayo was this to Liz Purr. She even calls her "The Cat's Meow"
- The Sociopath: Does Courtney mourn Liz's death? Just a little. Does she care about incriminating an unknown loser whom she had sex with, just to convince the police that neither she nor her "friends" were related to the case? Nope!
