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. A man stands there with his family, claiming to have lived there years before and asking if it would be alright if he showed his kids around. People pleaser to a fault, Eve lets them in. As soon as the strangers enter their home, uncanny and inexplicable things start happening.

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.

It’s the house of their dreams. Former marine Harry and his wife, Sasha, have packed up their life and their golden retriever, Dash, and fled the corporate rat race to live off the land in rural Idaho. Their breathtaking new home sits on more than forty acres of meadow, aspen trees, and pine forest in the Teton Valley. Even if their friends and family think it’s a strange choice for an up-and-coming pair of urban professionals, Harry and Sasha couldn’t be happier about the future they’re building, all by their lonesome.

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.
