This is a movie about Ramesh, a college student and his widowed mother Nandhini, and how their normal life takes a turn when a minister named Nadeshan, who has a grudge against them, is found murdered and they get suspected for the murder. But they are proven innocent because of city police commissioner Idiyan Kartha, with the help of CI Vigneshwaran and Nadeshan's twin, Dineshan. They find out that Minister Thankappan was the one behind the killing of Nadeshan, as Nadeshan mocked him for wanting to become the minister and Dasappan, who was the witness, helped him cover his crime. Finally, Ramesh is reunited not only with his mother, but also Julie and her friend. DGP Chandrakumar is disappointed not only that IG Stephen Tharakkan arrests him because of the pressure from the minister to arrest Thankappan.
