This realistic social drama delves into the life of Achuthan Nair (Thilakan), an honest police constable, and his loving family, consisting of his wife Ammu (Kaviyoor Ponnamma), two sons and two daughters. Achuthan Nair wants his elder son Sethumadhavan (Mohanlal) to become a police inspector.
He shares a cordial and amiable relation with his son. Sethu is engaged to Devi (Parvathi), the daughter of Krishnan Nair (Sankaradi), his maternal uncle. One day, for charging a petty case against the son of a Member of Legislative Assembly, Achuthan Nair is transferred to Ramapuram police station.
The family also shifts to Ramapuram. Keerikadan Jose (Mohan Raj), a hardcore criminal, rules the market of Ramapuram by extorting money from all traders. One day, Achuthan Nair tries to intervene in a scuffle and he is beaten brutally by Keerikadan. Sethu, who was in the market, witnesses it and saves his father by attacking Keerikadan and his goons. Keerikadan gets severely wounded and is admitted in hospital.
The entire market celebrates the fall of Keerikadan and finds a new savior in Sethu. His friends misuse this opportunity by creating a brawl in the local pub. Achuthan Nair is deeply disturbed by this and accuses Sethu of slowly turning into a criminal. Despite all his efforts to stay away from crime and violence, gradually Sethu finds himself dragged into issues only to get targeted by various criminal elements. Having been labelled by society as a 'violent criminal', will Sethu ever succeed in returning to a happy and peaceful family life?
