While going through a difficult divorce from her domineering, businessman husband, Alexandra moves back into her old childhood brownstone home, where she sets out to uncover dark family secrets from when she was a young girl, involving her Aunt Judith's murder and her mother's descent into insanity. The only clue is a key to a mysterious secret room that lies within the house. As a series of bizarre and unsettling incidents prod Alexandra to investigate her past, she finds herself wandering deeper into danger as her past comes back to haunt her.
Unfortunately the movie Forbidden Secrets is not yet available on HBO Max.
