After retirement from Indian Railways, as station master, Raghavan Nair (Thilakan) is back at his home. His long cherished dream to spend his retired life with his family consisting of his wife (Kaviyoor Ponnamma), three sons and two daughters gets a blow after seeing his two sons brawling each other over their political differences. Prabhakaran (Sreenivasan (actor)), the elder one is a staunch leftist, and an active worker of the Revolutionary Democratic Party (RDP), which has just lost the Kerala state Assembly elections and relinquished office. Prakashan (Jayaram), popularly known as KRP, his younger brother is involved with the Indian National Secular Party (INSP), which has now come to power. Though they are both educated, neither has any plans to earn a living on their own and are fully immersed in petty politics, sponging off their parents for their needs.
