This forest isn't charted on any map. Every car breaks down at its treeline. Mina's is no different. Left stranded, she is forced into the dark woodland only to find a woman shouting, urging Mina to run to a concrete bunker. As the door slams behind her, the building is besieged by screams. Mina finds herself in a room with a wall of glass, and an electric light that activates at nightfall, when the watchers come above ground. These creatures emerge to observe their captive humans and terrible things happen to anyone who doesn't reach the bunker in time.

As a young, queer couple who flip houses, Charlie and Eve can’t believe the killer deal they’ve just gotten on an old house in a picturesque neighborhood. As they’re working in the house one day, there’s a knock on the door.

As soon as the strangers enter their home, uncanny and inexplicable things start happening.

Deep in the heart of Appalachia stands a crooked farmhouse miles from any road. The Morrows keep to themselves, and it's served them well so far. When girls go missing off the side of the highway, the cops don't knock on their door. Which is a good thing, seeing what's buried in the Morrows' backyard. But 19-year-old Michael Morrow isn't like the rest of his family. He doesn't take pleasure in the screams that echo through the trees.

Near an isolated mansion lies a beautiful garden. In this garden grow luscious flowers, shady trees...and a collection of precious “butterflies” - young women who have been kidnapped and intricately tattooed to resemble their namesakes. Overseeing it all is the Gardener, a brutal, twisted man obsessed with capturing and preserving his lovely specimens.

It was a mistake to trust him. Shivering and bruised, a teen wakes up on the side of a dirt road with no memory of how she got there—or who she is. The police don’t know where she came from until a frantic man arrives at the station. He’s been searching for her for hours. He has her school ID, her birth certificate, and even family photos.
