Enter Sathya and Preetha of the S&P Investigation Agency, two detectives who specialize in cases the system leaves behind. Series 1 contains two gripping cases. In the first, a village drowning in land disputes hides a murder carefully designed to frame an innocent man. In the second, a serial killer known only as the Correction Killer is targeting people who escaped justice — using a mental wellness app to hunt victims across Tamil Nadu. Inspired by true events. Based in Chennai and the villages of Tamil Nadu. A crime series that asks: when the law fails, who corrects the world?
