Newlyweds Tricia and Ethan are house-hunting in the middle of a brutal, blinding winter storm when they find themselves stranded at a massive, isolated estate that once belonged to Dr. Adrienne Hale, a renowned psychiatrist who vanished without a trace years ago. Trapped inside by the weather, Tricia stumbles upon a hidden room containing audio transcripts of every single patient session Dr. Hale ever recorded. As Tricia listens to the tapes late into the night, she uncovers a chilling web of lies, psychopathic admissions, and severe structural deceptions connecting the patients to the doctor's disappearance, realizing they are not alone in the house.
