When Biju, a motherless boy, manages to win Vinodini's affections, he becomes attached to her. This platonic bond is misused by Krishnankutty and Shivaraman, two greedy men who are living off Biju's ancestral property and vast lands. The two fiends brainwash Biju into believing that Vinodini is passionately in love with him, leading to a tragic course of events.
