A body is found wrapped in plastic and dumped by a drain. Arun Kumar dreams of making a serial killer film and has been carefully doing research. Under pressure from his mother, he takes a police job from his brother-in-law. Beating suspects is standard operating procedure. A school girl goes missing in an apparent abduction. Arun investigates the case on his own but his disbelieving superior relies on the standardized beatings. A psycho is murdering young female students and leaving behind creepy doll's heads. Arun falls for his niece's teacher Viji.

This is a Tamil crime thriller mystery. I like most of this with a few minor reservations. I like the lead. The murder mystery is good but it does get a bit campy with the reveal of the killer. The climatic battle is part superhero and part camp action. The twist is obvious although I didn't figure that the mother would like that. The camp value in all that is higher than expected. It doesn't really fit the brutal gritty realism of the serial killing. Then there is the section of hilarious comedy with the initial meeting with Viji. Don't get me wrong. It's very funny but it doesn't fit the rest of the movie. This film has differing tones that don't always fit together. As for the police beatings, I think it's a great setup to Arun's dislike of this police tactic. Then when they are holding the suspect in the hospital, they start beating him up with Arun's approval. It seems counter to Arun's view on police beatings. All in all, I like most of this even with some of the problematic elements. It's a compelling crime thriller mystery.
