Varnajalam

Devanathan IPS (Nassar), a retired JCP of Chennai, begins a new life with his family, which includes his brother Shekar (Thalaivasal Vijay), sister-in-law Viji (Kanchana Mendis), and their children. Devanathan buys two large tea estates in Ooty and moves in with his family there. Devanathan's daughter Anitha (Kutty Radhika) is a teenager who wants to become a sincere IPS officer like her father, and his son Ashwin (Anand Samy) is a brilliant yet troubled and antisocial young man. One morning, a young man named Daniel (Srikanth) arrives with a recommendation letter from a recently dead priest, Father Andrews, who is a schoolmate of Devanathan, to apply for a job as a tea estate manager. Daniel slowly becomes a favorite of the family with his good nature, music skills, and along with the fact that he saves Devanathan's life from criminals, and wins the family's heart.

One night, Ashwin scares Devanathan by dressing himself as a stalker. Ashwin got chased by Devanathan and revealed his identity to him, while laughing insanely and madly at Devanathan. The next day, Ashwin drives too fast, almost kills the family from getting hit by a train, frightening them. He then gets into an argument with Devanathan and goes to Daniel's office. Daniel, while acting insanely, inflicts wounds on himself and blames it on Ashwin. Ashwin attempts to confront Daniel over this scene at the hospital that Daniel is recovering from. Daniel created a scene that fabricated Ashwin attempting to murder Daniel for presumably having an affair with Anitha. Ashwin was captured by the ward boys and guarded in the hospital. Daniel was discharged and stayed alone at Devanathan's house. Ashwin escapes his hospital room by locking Shekar, who was guarding him in the washroom, and confronts Daniel again at his home. Daniel starts a fire in the cabin, where all of Devanathan's awards and medals, blaming all of that on Ashwin. Ashwin attempted to stop and expose Daniel but was unsuccessful and is taken to a mental hospital. Daniel disguises himself as Devanathan by wearing his cap and black coat while spying on Viji when she is bathing. She thinks it was Devanathan, and the friction between the brothers starts, which grows to an end level when Shekar leaves the house.

One day, while riding her scooter, Anitha discovers Daniel's jeep and is shocked to see him performing Hindu rituals for a woman named Abhirami (Sadha). Daniel reveals himself to be Shakthivel, raised up by his elder sister Karthiga (Saranya Ponvannan) and brother-in-law (Nizhalgal Ravi). He was academically very brilliant, but when his brother-in-law suffered from paralysis, he voluntarily gave up his school studies and became a painter. He and his sister's daughter Abhirami are in love. Abhirami enrolled herself in a medical college to become a doctor as her wish, while Shakthi covered the expenses and fee payments. Abhirami's parents plan their marriage after Abhirami finishes college. On Devanathan's last day in service, a junior officer, ACP Prabhakaran IPS (Ajay Rathnam), requests him permission to perform an encounter operation on a famous rowdy called Royapuram Guna (Riyaz Khan). Unbeknownst to anyone in particular, Devanathan is under Guna's payroll. Though Devanathan refuses permission, the chief minister overrides him, and the operation is carried out near a bus stop, where Abhirami was standing. Guna escapes due to Devanathan's prior given information to him, but Abhirami is killed in the crossfire of the shootout between Guna and his gang against the police. To save their names, Devanathan places Guna's photo inside Abhirami's work folder and fabricated her as like his lover. Shakthi is innocently arrested and sentenced for about six months in imprisonment for beating up policemen who came to question him and Abhirami's parents for Guna's whereabouts, while Abhirami's parents commit suicide over humiliation of the false fact of Abhirami being Guna's lover. Devanathan retires with honors. Prabhakaran was guest visiting the prison that Shakthi was imprisoned in and revealed to him the truth when confronted by Shakthi and apologizes to him over being unable to do anything to reveal the truth, due to the fact that Devanathan was his superior officer and higher official.

Anitha could not believe it at first, but Shakthi forcibly took her to the guest house that Devanathan brought and showed her him chatting on a escape plan for Guna and his friend, who were hiding in Ooty by Devanathan to escape from the authorities. She was shocked to learn that her father is a murderer and ran away from Shakthi. Guna and his friend are about to escape to Ooty in a vehicle driven by Devanathan himself to avoid unnecessary checking. Shakthi chases them, and when they are about to cross a check post, he shoots at the car. Guna and his friend mistakenly thought it was police firing, so they came out and start firing, which triggers the actual and real police to come to the spot and kill Devanathan and the criminals in the shootout. Shakthi revealed his identity to Devanathan before he died, while stating that having him killed in the same way Abhirami was killed is Shakthi's punishment to him.

At the film's end, Shakthi is seen sitting in a bus leaving Ooty reading an article on a newspaper of Devanathan's death, with Anitha revealing the truth about her father being a criminal to the entire world written in it.

The soundtrack was composed by Vidyasagar.
