In the quiet, everyday rhythms of her life, Sarah, a socially awkward craft store employee played by Alison Brie, finds solace in two things: her beloved childhood horse and her favorite supernatural crime drama. A gentle soul living a regimented life, her world is carefully managed with the support of her roommate Debby Ryan and a tentative connection with a sweet customer John Reynolds. Yet, Sarah's grip on reality begins to fray as she experiences increasingly vivid and disturbing dreams, sleepwalking episodes, and eerie coincidences that blur the line between her mundane existence and the haunting television series she adores. Directed by Jeff Baena and co-written by Alison Brie, this unsettling drama and psychological mystery follows Sarah's desperate quest for answers as she pieces together fragmented memories and family history, leading her down a rabbit hole where genetics, paranoia, and otherworldly possibilities collide. The film masterfully builds a tone of creeping unease, painting a poignant and sometimes darkly humorous portrait of a woman trying to distinguish haunting truth from terrifying delusion before she loses herself completely.
