Ashes (2020)

The walk from school of two sisters will be altered when the youngest takes an unexplored path into the woods that leads her to a disquieting abandoned institution. Mesmerized by the building, the girl founds a scorch sketch book that warns about a menacing presence surrounding her, but her innocence doesn’t let her see that her life is in danger.

Unfortunately the movie Ashes is not yet available on HBO Max.
