31 December 2010: At 11:59 pm, a sudden bomb blast occurs in London, killing several people.

After a year, A blind man named Kenny Thomas lays flowers on the memorial and mourns someone's death during the bomb blast. He is provided with secret details by a mysterious woman. Kenny then takes a taxi driven by Sathyan, a comical Tamilian. He drops Kenny at a place and waits for him to return, but Kenny goes inside, kills a person and throws him down.

Seeing the corpse, Sathyan flees; Kenny is shown to produce a sound from his mouth to find his way, which is later shown as echolocation. Kenny plays the piano in a church, and as he is blind, he has many people care for him. In the meantime, he carries out two more murders, taking the same taxi driven by the innocent Sathyan, following instructions from the mysterious woman.

Sara Vinayagam, a British-born Anglo-Indian woman, wins the Miss London title, and to build her social profile, she goes to Kenny's church and acts like she is helping out there. Initially, Kenny does not like her, but eventually, they become friends. Sara's father is a doctor, who supports Kenny. Inspector Veerakathi, a British Tamil citizen, is the officer in charge of investigating the murders.

As the autopsy of the murdered victims takes place under Sara's father, Veerakathi visits him and learns about Kenny, who is admitted there for a small accident. Veerakathi initially suspects Kenny but is not convinced. Sathyan is found at all the murder locations, and the police arrest him; suspecting his involvement in the murders. Sathyan manages to find a picture of Kenny from a local newspaper and informs Veerakathi.

Sathyan is released and meets Sara. Both of them go to a place (one that she learns of from Kenny's phone, which he missed during a fight with local thugs). They reach there in time to see Kenny almost kill a steel company owner named Victor. Kenny flees the scene after sensing them and takes Sathyan's taxi to escape. Due to his blindness, he runs the taxi into a river, along with Sathyan and Sara. They get out and reach the riverbank. While escaping, Sara and Sathyan are stopped and confronted by Geetha, who reveals Kenny's real identity:

Past: Kenny was a RAW officer in India, whose real name is Shivakumar. Shiva and his close friend Sharath completed various missions for the government. Shiva married Meenakshi, a conservative eye doctor in Delhi. Initially distant, as time goes by, both became closer to each other, albeit without expressing love for each other. Meenakshi had decided to express her love to Shiva on New Year's Day (which turns out to be his birthday).
