Thakara (Prathap Pothan) is an orphan. He is mentally immature, but kindhearted. He has a close relationship with Subhashini (Surekha), the dream girl of the village. Thakara was betrayed by the words of Chellappanashari (Nedumudi Venu) and indulges in a physical relationship with Subhashini. Subhashini's father Mathu Mooppan (K. G. Menon) finds out their relation and beats Thakara unconscious. Thakara, fully filled with revenge on Mooppan, runs away. Once he earns enough money to buy a knife, he returns and kills Mooppan. Subhashini refuses to go with Thakara, who proposes to her after killing her father. With no way to escape, Thakara finds his end in front of a running train.
