Amid incessant rains pounding down on Mumbai, Senior Inspector Arnav Singh Rajput is called to a shocking crime scene. A male body is found dismembered on the steps of a Kaali temple. Drawn into his flesh are symbols of a tantra cult. The desecration of a body at a Hindu place of worship puts the city on edge and divides Arnav’s priorities: stopping a fanatic from killing again and caring for his wife who’s struggling through a challenging pregnancy. Then video footage of the murder is uploaded onto the account of a Bollywood social media influencer, triggering twists in the investigation Arnav didn’t see coming. Caste systems at war. A priest under suspicion. And an anonymous threat that puts his wife’s welfare at risk. When more bodies are found, the savagery of the city begins to surface—and Arnav fears that no one is safe from a bigger storm brewing.
