The sudden death of a priest right in front of his teenage son sends people in a frenzy. 11 years later, Nikhil Nair, a forensic expert teaching at the FBI HQ, receives coordinates of an unknown location from a mysterious source only to find out a completely mutilated, tortured and charred body back in India. With a killer responsible for a murder that can make even the toughest cops shudder on the loose, Dr. Dhananjay Rajpoot, a forensic expert is set on a wild goose chase.

The investigation takes a wild turn as Dhananjay finds out the mutilated and charred body found earlier was in fact of his wife - Sandhya. But even before he could come to terms with the inconceivable loss, Dhananjay is arrested for murdering his wife. With the clock ticking, and the pressure mounting, another body with the same mask is recovered from Nagaland.
