Plot

The film opens with a flashback showing a feud between the families of Sathyaprathapan and Bhavani. Sathyaprathapan's sister and Bhavani's cousin are in love. The murder of Bhavani's cousin Vishnu is wrongly blamed on Balagangadharan, father of Sathyaprathapan. Sathyaprathapan's sister commits suicide and Sathyaprathapan turns against his father, who dies soon. He starts to help Bhavani's family and mortgages his own house to finance her factory. Feelings of love develop between Sathyaprathapan and Bhavani. But Bhavani's greedy father wants to destroy Sathyaprathapan's family and tries to take their home. That is when Parameshwara Pillai (Sathyaprathapan's uncle) shows up. Sathyaprathapan's mother requests Pillai to prove Balagangadharan's innocence. Pillai and Sathyaprathapan find Kuruvilla who had witnessed the murder being committed by the goons sent by Bhavani's father. Meanwhile, Sathyaprathapan's mother faints and dies in the hospital. While in the hospital, his mother tells how Balagangadharan had a different wife and he should ask them forgiveness. He storms into Bhavani's house and accuses her dad of destroying his family, also trying to make her understand the truth but she does not believe him and stands by her father. Then Sathyaprathapan says he does not love her any more and vows that he will never trust a woman and remain a bachelor forever.
