Prasanna is a young man who indulges in several revolutionary activities against the wishes of his father Mahendran, a widower. After Prasanna tells him that, due to the price of rice increasing, he stole rice from a lorry, distributed it to the poor and set fire to the lorry before the police arrived, a disgusted Mahendran helps the police arrest him, widening the already existing rift between them. After his release, Prasanna opts to stay away from his hometown, Bangalore, and reaches Madras.
