In the bustling city of Indore, DI Arjun Rana, a weary but resolute homicide detective, confronts a series of baffling murders. A wealthy industrialist staged with an antique sword. A student activist posed by the river with an earthen effigy. An elderly archivist silenced amidst his research. The only link: a chillingly precise, microscopic symbol carved onto each victim - an unbalanced scale.

As public fear mounts and political pressure intensifies, Rana realizes he's hunting no ordinary killer. This perpetrator, calling himself 'The Arbiter', operates with scientific sophistication and forensic awareness, driven by a complex historical grievance stretching back two centuries to the era of Holkar rule and Maratha conflict. Rana, aided by tech-savvy SI Priya Sharma, must race against time, delving into fragmented archives, forgotten lineages, and the city's own buried past to understand the Arbiter's narrative before his deadly historical judgment reaches its catastrophic conclusion, timed for a significant anniversary at the heart of Indore itself. Can Rana decipher the secrets history tried to erase before the Arbiter balances the scales forever?
