In the heart of the Appalachian mountains, Sarah lives a solitary life with her reclusive, moonshining father, Jedediah.
His "special brew" draws rough men seeking an unnatural high, but also emits strange, unsettling sounds and a cloying, metallic scent that prickles Sarah's skin.
Her mother, Martha, died years ago, a mystery Jedediah dismisses.
Sarah's growing unease explodes into terror when she glimpses grotesque, pale "human forms" within her father's rickety still house.
Her dread turns to horror after a stranger, Caleb, reveals a chilling truth: her mother wasn't just dead-she was the first "Source" for Jedediah's vile concoction.
Jedediah, sensing her prying, drags Sarah into the reeking still house, forces her to touch a pulsing, disturbing "mash," and unveils a horrifying family "legacy," subtly threatening that she is destined to become a "Source" herself.
Caleb, her supposed ally, then reveals his own sinister agenda: not to save, but to control the monstrous operation, leaving Sarah truly alone.
This isn't tradition; it's a waking nightmare.
Sarah is consumed by absolute horror and a sickening realization: her own mother was tortured for this brew, and now she is next. How could her father be such a monster, and why is she caught in this grotesque fate?
Determined not to become the next victim, Sarah confronts her monstrous father, only to witness Caleb's brutal murder.
But just as Jedediah moves in for the kill, a terrifying, primal force-long imprisoned, yet impossibly alive-begins to stir from the cellar's depths, ready to exact its terrifying, final reckoning.
My name is Sarah. I live way up in the Appalachian mountains with my pa, Jedediah.
The homestead is old, falling apart mostly.
Pa makes moonshine.
Not just any moonshine, he calls it his "special brew."
Men from all over the hollows, rough men, loggers, miners with no mines, they come for it.
They say it' s potent, gives them a kick, makes them feel young again.
They always go to the still house with Pa, a rickety shed set off from the main cabin, deeper in the woods.
Hours later, they come out, faces flushed, eyes bright.
But over time, they look...drained. Always needing more.
I' ve never seen how he makes it.
Never seen the "ingredients."
Pa says it' s a family tradition, his secret.
He says Ma, Martha, died years ago. A mystery.
I' m starting to wonder about that. About a lot of things.
The air around the still house always smells funny.
Sweet, but also like something else, something I can' t name.
Something that makes the back of my neck prickle.
The men come at odd hours, their trucks rattling up the dirt track.
Pa meets them, his face grim, gaunt.
He' s not a big man, but he has a way about him, a dark shine in his eyes that makes even those rough customers quiet down.
He leads them away, and I stay in the cabin.
"Not for young girls to see, Sarah," he always says.
His voice is low, like stones rubbing together.
I' m almost twenty, not a girl. But I don' t argue.
Not with Pa.
The money from the brew keeps us fed, keeps the roof, leaky as it is, over our heads.
But there' s a coldness to it, a coldness that seeps into the cabin even on hot summer nights.
I watch them go, and a knot forms in my stomach.
What happens in that still house?
What makes that brew so special, so craved?
And why does the thought of it make me feel sick?
Pa has rules. Lots of them.
The biggest one: stay away from the still house.
Especially when he' s "tending to the mash," or when customers are around.
"It's men's business, Sarah. Delicate work."
That' s what he tells me.
But I hear things.
Late at night, when the wind is low, sounds drift from that shed.
Moans. Sometimes a soft cry.
It' s not animal, not quite.
"Just the brew settling," Pa says if he catches me listening. Or, "The mountain winds play tricks on your ears, girl."
His eyes get hard then, a warning.
Sometimes, the customers, when they' re leaving, full of Pa' s brew and false cheer, they' ll say things.
Lewd things, under their breath, but I hear them.
"Jedediah' s got some fine stock back there."
"Keeps 'em fresh, he does."
If Pa hears, and I' m nearby, he gets furious.
His face darkens, and he' ll snap at them, "Mind your tongues! Show respect!"
It' s strange, his anger. It' s not about me, not really. It' s like they' re talking about something sacred to him, something he owns.
And then there's the other rule, the strangest one.
When my monthly time comes, Pa gets real agitated.
"Womanly scents can spoil the brew, Sarah. Turn it sour."
He forbids me from going anywhere near the still house then.
Says I have to stay in the cabin, or go far down the mountain.
Spoil the brew? How?
It makes no sense.
But the fear in his eyes when he says it, that' s real.
It makes my own unease grow, a cold vine wrapping around my heart.
The sounds, the comments, Pa' s strange fears... it' s all connected to that still house, to his "special brew."
And to Ma.
He says she died. But the way he talks about her sometimes, possessive, almost like a fanatic... it' s not how you talk about the dead.
It' s like she' s still here, somehow.
A part of his secret.
