A man embarks on a bloody rampage to save his kidnapped brother.

Legend goes in Siddhpur that anyone who stays in the Shiva temple post sunset, is punished by Lord Kaal Bhairava. Investigating the mysterious death of his brother brings Rahul to the temple.

The series is inspired by a reference to Naag Lok in the Mahabharata where one of the greatest warriors, Arjuna married Ulupi, a Naga princess. She was the one who saved him when he was cursed by the Vasus for killing Bhishma through foul means.
