Raghav and Mythili work for a company that runs ghost-walking tours in the town of Kishkindhapuri. They’re not just colleagues but also a couple. During one tour, they take a group of people to an old radio station, Suvarnamaya. An antique radio suddenly starts functioning, terrifying everyone. Raghav senses a supernatural presence and helps others escape from the haunted place. Soon after, every visitor who entered Suvarnamaya begins dying mysteriously one after the other.
