Ravi Varma (Sreenivasan), Kesava Pillai (M. G. Soman), Prabhakara Varma (Karamana Janardhanan Nair) and Rajaraja Varma (Maniyanpilla Raju) seek methods to kill King Udaya Varma Thampuran (Nedumudi Venu) to usurp his wealth. Udaya Varma's wife Bhagirathi Thampuratti (Kaviyoor Ponnamma) has fallen into depression after the untimely death of their son Unni. She is locked up at home and looked after by Udaya Varma's daughter Radha (Gautami). Ravi Varma and the group fear that Udaya Varma might will his wealth to Radha, being his adopted daughter, who is believed to be born of an illicit relationship of Thampuran's maid with another servant. The group is helped by Cheriyachan Thampuran (Thikkurissy), a blind cousin of Thampuran, who also eyes King's wealth. He advises the group on the plans to eliminate the King upon condition of sharing the wealth with him. As per his advice, Ravi Varma travels to Mumbai in search of a killer. There he meets Jamal (Mammukoya) who helps him. He introduces Ravi Varma to Abdhullah (Mohanlal), who is a singer in Mumbai. Abdhullah is in need of money and upon persuasion from Ali, goes to Kerala planning to kill Thampuran.
