A movie by Taylor Compton

A struggling children's book author and his rebellious teenage daughter move into a house they've inherited and find mysterious dolls in the attic. The father and daughter soon learn that the dolls have a sinister - and deadly - past.

Set in Colorado’s Rocky Mountains, the story follows Nadia the night before her childhood home is sold. High on mushrooms, she and her friends inadvertently open a portal, plunging them into the astral-plane. There, she must face The Horned One, an ancient keeper of the land and of the water. To return to her body, Nadia must come to terms with her responsibility to her homeland and the water that it protects.
