Murdered in 1925, Katy Watkins, an eighteen-year-old debutante, finds herself near a worn-down cabin. She doesn’t know where she is, so she heads home and discovers two strangely dressed girls in her bedroom window. When her memory does return, a demon hunts her—this demon is her killer. She walks in the woods trying to get home, stuck in a loop until she meets Lila and Rose. Sixteen-year-old, bipolar Lila has disappointed her family. It was hard for Lila to cope after her father’s suicide, which soon forced Lila, her mom, and her fifteen-year-old sister, Rose, to live with their aunt and uncle in Parkville, Missouri. They discover a ghost tied to an old murder mystery, and Rose begins to film a documentary at a nearby cabin. Rose is possessed by Katy, which makes her sick. In order to save Rose’s life, Lila and Rose help Katy uncover the truth regarding her murder: she was murdered by her sister, not her fiancé as they first suspected. After Katy forgives her sister, she crosses over. Katy’s sister cannot forgive Katy so she remains a demon wandering in her hell forever. Lila and Rosa see their deceased father when Katy crosses, and they forgive him, freeing him from his prison.
