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. Dismissing the curse as superstition, Arjun pushes forward with wedding preparations, only to encounter increasingly sinister supernatural events within the palace. As the truth behind Acharya Niwas begins to unfold and his father arrives with a horrifying secret, Arjun must confront an evil far more powerful than he imagined to protect his family and survive the wedding that could seal their fate.
