The Movie opens with a crime where a young man is beaten to death with a club in front of his fiancé. Then comes an investigation officer Alexander (Sreenivasan), and an assistant Ramachandran (Vinay Forrt). Though Alexander is intelligent enough to prove crimes unlike he doesn't believe in torturing the accused people to prove crimes. Parallel to this, Harsha Vardhan (Dulquer Salmaan), a man of mystery, lives lonely in a big house, and teaches music to a girl named Sophie. He one day kidnaps and brings an auto driver (Anu Mohan) and tortures him in his house cellar. Alex and Ramachandran take up the case and upon investigation, Alex suspects Harsha. He kills the auto driver, severs his body and then eradicates every single evidence which proved him guilty. Once the severed parts are found, the case heats up further and Alex realizes that it's a well planned murder, only after he finds Harsha had left the city without any notice.
