Mahanadhi

Krishnaswami (Kamal Haasan) lives a comfortable life in a village with his children and mother-in-law. Lured by the greed to make more money, Krishnaswami falls an easy prey to the trap set by Dhanush (Hanifa). Krishnaswami starts a chit fund with Dhanush as his partner who runs off with the money, leaving Krishnaswami to face the wrath of the depositors. He is proved guilty and sent to jail. His young children are looked after by his mother-in-law but as time passes by, they fall into bad days. Their only source of comfort is Yamuna (Sukanya), whose father (Poornam Viswanathan) happens to be the cell-mate of Krishnaswami. The old lady dies and Krishnaswami's children are left to fend for themselves. The daughter is forced into prostitution by Dhanush while the boy joins a road-side circus. On being released from jail, Krishnaswami alongwith Yamuna and her father try to trace out the children. While the son is located easily, the search for daughter takes them to the brothels in Calcutta city. Framed in a murder case by Dhanush, Krishnaswami decides to take the law into his hands and kills Dhanush and his accomplice.
