Staring:- Arjun Sarja, Prasanna, Sruthi Hariharan, Varalaxmi Sarathkumar
Ranjith Kalidoss (Arjun) is a Deputy Superintendent of Police (DSP) in CB-CID, who along with his partners Inspector Joseph (Prasanna) and Inspector Vandana (Varalaxmi Sarathkumar), takes on high-profile cases and closes them successfully. Counter to his high intensity job, Ranjith has a peaceful family life with a wife Shilpa (Sruthi Hariharan), daughter Oviya (Baby Swaksha), younger brother Sandeep (Vaibhav), and their family dog Rocky. Ranjith's boss assigns his team a task to pursue a group of five criminals, who continue to avoid justice with their influence and power. Ranjith suggests a more direct approach to taking them out, but his boss declines to go along with it.
Before they could pursue the current assignment, they get dragged into another mystery. A parcel arrives at the police station one day that contains a small horse doll hanging on a noose. The figure has four holes but otherwise no other clues. Not thinking much of it, the team decides to ignore it. A few days later, a local communist leader goes missing. He is later found in warehouse hanging from the ceiling, tortured, shot, and his face covered in an animal mask, very much like the doll they received.
