Udaya Geetham

Arun is a singer sentenced to death. He meets Shanthi, a fan, during one of his concerts and she follows him on many occasions both within and outside prison. Arun shows deep animosity towards Shanthi's behaviour and continuously shuns her, but a persistent Shanthi refuses to give up. Maari, an inmate, attempts a prison escape but is stopped by Arun. He tells Arun about his sick daughter, and his inability to pay for her operation. A sympathetic Arun promises to raise funds for the sick child through his next concert, which he also plans shall be his final one.

Leela Chowdhry is the newly appointed Superintendent of Police for the Madras Central Jail, where Arun is imprisoned. Shanthi talks her into getting her married to Arun, who also agrees to it after deeply thinking and deliberating. The wedding takes places in Leela's house. During their wedding night, Shanthi stabs Arun and reveals herself as the sister of Anand, for whose murder Arun was convicted. Anand was Arun's musical partner in their troupe before his murder. Arun claims he was wrongfully convicted and Shanthi, believing him, promises to clear his name.

Leela allows Shanthi and Arun to go to a nearby temple, but sends policemen along with them to prevent Arun from escaping. Shanthi outsmarts them and takes Arun to her home where she imprisons him, much to his dislike. She makes it seemingly impossible for him to escape, until she is able to prove his innocence. Leela is later punished for having let Arun "escape", and simultaneously realises that Arun is her long lost son, becoming heartbroken. However, she remains bound to her duty of capturing Arun, and a manhunt for him begins.

Shanthi later meets Shankar, the real killer of Anand. He admits to the murder, but states that did so because he witnessed Anand sleeping with his wife. Shanthi, knowing that Shankar's wife is promiscuous (it was she who seduced the reluctant Anand), takes him to her and Shankar is angered on seeing his wife with another man in bed. He kills her, but not before she mortally wounds him. Arun, having escaped, is confronted by Leela who he realises is his mother. She allows him to perform his final concert, but has to have him hanged to death him after that. Right after he finishes his concert he is arrested, but Shanthi and Shankar finally arrive and tell the truth about Anand's death, after which Shankar succumbs. Arun's death sentence is revoked.
