Output: Vijay Kumar Vijay is the honest and sincere DCP of Chennai. He takes up a case involving the rape and subsequent death of an IT employee Raji. He finds out that the rapist is Ashwin, the son of Labour Minister Vanamaamalai J. Mahendran. Vijay kills Ashwin and reveals himself as the murderer to Vanamaamalai, who swears to take revenge on him for killing his son. Meanwhile, Vijay falls in love with a medical student Mithra Samantha Ruth Prabhu and both eventually get married and lead a happy life. But, Vijays happiness is shortlived as Vanamaamalai, his younger brother Ratnam Azhagam Perumal and their henchmen barge into his house one night and kill Mithra and Vijays mother Raadhika. They even brutally assault Vijay and attempt to drown Vijays baby daughter Niveditha aka Nivi in the bathtub. The dying Mithra manages to rescue Nivi and asks Vijay to take care of her, but not before making him promise that he will quit the police and be a peaceful and loving father to Nivi, following which she dies in Vijays arms. Vijay fakes his death, changes his name to Joseph Kuruvilla and moves to Kerala with Nivi and his constable friend Rajendran Rajendran to protect Nivi from Vanamaamalai and his gang. Five years later, Vijay is leading a happy life in Kerala with Nivi Baby Nainika, who is now in kindergarten, and is running a bakery with Rajendran. As per Mithras dying wish, he gave up violence and raises Nivi to be nonviolent. He meets Annie Amy Jackson, Nivis class teacher, and both become good friends. Annie soon finds out about that Joseph is none other than the late Vijay Kumar, but Vijay warns her not to tell Nivi about it. One day, while Nivi is going on an excursion, the brakes of the school bus in which Nivi is travelling fails and the bus plunges into the backwater. Vijay, with the help of Annie, Rajendran and the local people, manages to rescue Nivi and the other children. He finds out that Vanamaamalai, who has found out that he and Nivi are still alive, is responsible for the bus plunging into the backwater in order to kill Nivi. Enraged, he decides to abandon his nonviolent principles and destroy Vanamaamalai and his gang once and for all. Vijay, posing himself as the ghost of Vijay Kumar, starts eliminating Vanamaamalais henchmen onebyone. He first kills an inspector Karikalan Stun Siva, who is one of Vanamaamalais henchmen and was present at the night when Mithra was killed. The police are baffled at the murder as it was done within the police station, and refuse to believe that Vijay committed the murder, since they think that he is dead. The mysterious deaths continue, with Vijay pushing Ratnam to his death from a highstorey building being constructed by him. Vanamaamalai is accused of killing Ratnam since both had fallen out, forcing him to go into hiding. Finally, Vijay allows himself to be captured by Vanamaamalais henchmen in order to enter his hideout. After eliminating Vanamaamalais henchmen, Vijay kills him. The police soon arrive at Vanamaamalais hideout, only to see his dead body hanging from the ceiling, and with nobody else around, his murder also gets sensationalised in the media as a mysterious murder. It is soon revealed that the Chennai commissioner of police Sibi Chakravarthi Prabhu Ganesan is aware that Vijay is alive and secretly reemploys him in the police to reduce crime in Chennai in his ghost form, taking advantage of the fear the negative elements of the society have for Vijay, while publicly denying that he is still alive. A few years later, Vijay, an older Nivi Divya Saasha, Annie and Rajendran have moved to Ladakh, with Vijay having changed his name to Dharmeshwar. But he continues to work secretly for the CBI, eliminating crime in his ghost form.
