The film starts with a masked killer entering an apartment and murdering a young couple, Krish and Shruti one cold, rainy night in Coimbatore. Five years later, Deepak, the retired police inspector who lost his leg while investigating the case, receives a call from a friend. The friend's son is adamant on becoming a police officer. So, the friend sends his son to Deepak so Deepak can brainwash him into not joining the force since his parents feels it is too dangerous. When the son arrives, he asks Deepak to tell him how he became crippled. Deepak begins to narrate his story of the final case that robbed him of the job he loved.半晌，他脸上讨好的笑容褪去，转而换上得意阴狠的神色：“没想到啊，陈市首这么快就发觉了，我本来以为还要过一段时间呢。”
