Arjun Acharya, a financially troubled man in his late 30s, unexpectedly inherits his grandfather’s massive ancestral palace, Acharya Niwas, in a remote North Indian town called Mangalpur. Seeing an opportunity to fix his life, Arjun plans to host his sister Meera’s long-delayed wedding at the palace. However, the town is gripped by a terrifying legend—no weddings take place in Mangalpur because a dark, ancient entity abducts brides and brings death to all involved.
