As its title hints, Teenage Sex and Death at Camp Miasma is many things all at once.
It's a horror film, of course, a gore-splattered homage to slashers of the past that reclaims problematic tropes which offend and resonate in equal measure. It's also a comedy, poking fun at the absurdity of death and the Hollywood machine alike. But most importantly of all, Jane Schoenbrun's third evocative feature is a love story.
Queer filmmaker Kris (Hannah Einbinder) and scream queen Billy Presley (Gillian Anderson) fall for each other in the actor's remote cabin home.
But as death approaches in the form of a killer literally named Little Death, Kris learns to let go and fall in love with herself too, connecting with her own body at last through the euphoric, intertwined release of orgasm and death.
Wrap this all up in what's clearly a love letter to the titillating pleasures of horror at large and what you're left with is perhaps the strangest yet most romantic film of the year. Who says love can't be profane and profound all at once?
Let's dive to the bottom of the lake in Teenage Sex and Death at Camp Miasma and take a closer look at the hidden meanings that lurk just beneath the surface.
Teenage Sex and Death At Camp Miasma ending explained
Plans for Kris to resurrect the Camp Miasma franchise with Billy's return are soon sidelined when something else is reignited instead.
Secrets are shared as their courtship escalates until it all comes to a head while watching Camp Miasma together, the film Billy herself starred in all those years ago. We too watch the film-within-the-film as we come to learn why Little Death seeks revenge against those who wronged them all those years ago.
Things intensify as we approach young Billy's sex scene. Present-day Billy digs her pencil harder and harder into the sketchbook on her lap until it snaps. At that point, she murmurs one word, "Rise", and then, suddenly, the camera used within the film becomes one with Little Death.
What ensues can only be described as a gleeful massacre where the killer takes centre stage, murdering everyone in their path to the sound of a nifty Counting Crows track called A Long December.
After so many horrors villainised characters who were confused about their gender, Schoenbrun gives the so-called monster a chance to take the wheel and strike back. But the action doesn't stop there. Just as young Billy is about to climax in the film, the power cuts out, pulling us back into the present.
It's there that Kris ends up holding a fraught zoom meeting with the studio she's supposed to be developing this Camp Miasma reboot for. Inspired by the other realm she was transported to watching the film last night, Kris begins to outline her new idea, that there is a hole at the bottom of Lake Miasma where the movies come from, one that predates everything, even the murders that inspired it.
Is it a meta take? You know, like Wes Craven’s New Nightmare?
"The hole is realer than this call," says Kris. "You all are characters in a movie."
She's not wrong, either.
What is happening under the lake?
As Kris speaks, we cut to a Lynchian room at the bottom of the lake where pink walls pulsate as if they were alive. The walls are lined with VHS tapes. Little Death (Jack Haven) stands at the centre, no longer in need of a mask or clothes for that matter either.
"We’re his little playthings," Kris rambles. "We are a movie for him to edit, and he has final cut."
Kris has broken through the fourth wall, not to us, the audience, but to Little Death, realising that he "is creating what we create, through us, as a vessel".
The movies are actually his creation, and what's happening now is just the latest film of his unfolding, building to a climax before it can then be added to the wall of other VHS movies at last.
The idea is that stories are told through us. We are not the architects we think we are.
But how did Kris tap into this higher level of consciousness? The answer lies in a conversation she and Billy shared about that sex scene Kris has long been so obsessed with.
How did Kris figure out the truth?
Like Kris, Billy struggled to enjoy sex after she was sexually assaulted while filming that sex scene in Camp Miasma. As Little Death entered, Billy began to disassociate, imagining the joy of orgasming by watching herself through his eyes, right on the cusp of death.
In doing so, Billy connected to something outside of herself, becoming the killer leering at herself while also being the girl who was watched, both breathing hard for very different reasons. "I caught a signal," says Billy, and then she orgasmed.
With that, the lake opens up and light pours out, transforming the snowy winter of "reality" into a summer fantasy. It's not so much a fantasy as it is the true reality they now inhabit, crossing over into the world of the original film that Billy starred in and Kris grew up watching.
They're not just following a script though. As Little Death advances with a spear in hand, Kris asks what she should do next. Billy's response? A push down the hill, forcing Kris to run from him for real.
"Sorry, I’m like, I’m a fan, obviously," she says to the killer. That's when Kris strips down to her T-shirt and underwear, running off through the woods in slow motion.
With that '80s synth pulsing in time to her breath and the braless heft of her shirt, Kris has finally surrendered herself to the film completely, becoming the Final Girl she always idolised.
How do Kris and Billy escape Little Death?

People from Kris's life appear then, including her girlfriend, Mari (Jasmin Savoy Brown), and Mari's boyfriend, Thor (Aren Buchholz). They end up the same way that Kris’s agent (Sarah Sherman) and the studio execs from earlier do; with a spear pushed through various organs.
Note how the latter die just as they ask Kris to make her reboot a "little bit more commercial," mirroring Schoenbrun's own pressures as a filmmaker in real life.
Meanwhile, Billy has been lighting candles and laying rose petals on a bed in Bunk 5, waiting for the climax. And climax they do, but not before Billy urges Kris to do what she did all those years ago, to watch herself through the eyes of Little Death.
That's when we suddenly approach the pair from the killer's perspective as Kris narrates everything that's happening. "Billy, I don’t want to die," she says before begging, "Billy, please don’t leave me." Fear and arousal and death intertwine as Little Death plunges his spear through Billy and Kris who lies underneath Billy on the bed.
Surprise and pain and pure ecstasy dance across Kris's face as the blood erupts.
And then stillness.
Satisfied, Little Death carves a 15th notch into the wall, corresponding with the number of Miasma films he has created. We see that creation firsthand then as the pink wall below the lake pushes out a new VHS tape that stars Kris and Billy on the sleeve.
Both women tapped into the desires that were broadcast from this room, tying together their struggles with disassociation and sex until they gave in and found a new path forward. Together.
Did Kris and Billy really die?
Death is not the end of their journey. Morning comes and the pair awake.
They did die, but they are reborn now, newer versions of themselves no longer burdened by shame.
Kris and Billy walk through the woods together and wind up at the gas station where our story began. Still covered in blood, they walk the aisles and fill their trolley with all kinds of candy. A man in the station stares at them aghast, shaking his head at the state of them. The woman behind the till also stares, but in awe, before complimenting Kris and Billy on their outfits.
They no longer have a care in the world. By giving into their desires and the essence of who they are at their core, Kris and Billy are able to let their freak flag fly with sheer abandon. They're not "normal" and they like it that way.
Outside, something important suddenly dawns on Kris .
"He’s still down there, you know. At the bottom of the lake. He’s still hungry. Can you feel it? He’ll be back soon to feed again."
This warning, much like the one given at the end of Camp Miasma: Part VI, should be worrying, but instead, Kris smiles at this realisation. So too does Billy.
Notice how this final scene uses the "split diopter" trick that Kris called out earlier when she was watching the original Camp Miasma. This old lens trick can hold two perspectives in sharp focus at once. This time, simultaneously focusing on Kris in the foreground and Billy behind her. The pair hold equal footing now, sharing a new outlook following their "little death".
What does it all mean?

Where sex and desire once equaled death, the opposite is now true. In fact, all these assumptions that the horrors of yesteryear perpetuated, that pureness will keep you alive, that queerness is monstrous, are dismantled entirely by the end.
Schoenbrun goes out of their way to deconstruct the very same genre that they clearly love, peeling back academic layers to reveal more primal urges that lurk beneath, much like the desire that Little Death represents waiting still under the lake.
In short, you can dissect the film all you want, but at the end of the day, only two things really matter: "Flesh and fluids."
