What if what you saw wasn't just in your mind? Dr. Meera Sinha, a reclusive psychologist haunted by a tragic past, witnesses something horrifying from her high-rise apartment balcony-what looks like a woman being strangled inside the mysterious new apartment across from hers, 9B. But when the police investigate, they find no signs of struggle. No woman. And the man living there insists he lives alone. Meera is told she's hallucinating. That it's her trauma resurfacing. But she knows what she saw. As she begins her own investigation, Meera uncovers chilling secrets-missing persons, a patient file that shouldn't exist, and a connection between her past and this haunting new mystery. Is Meera losing her grip on reality... or is someone gaslighting her into silence?
