Mahendhranath aka Mahi, only a few days old when he was born, had to move out from his birthplace with his grandfather. Mahi was the child of Raghunath and Meenakshi, who were in deep love, but he was born before their marriage. Fearing embarrassment, Meenakshi's father Vamadhevan decided to kill the baby without even considering his daughter's situation. He gave the baby to Velayudhan, his family manager to kill the baby, but his conscience wouldn't allow him to do so, and he gave the baby to his grandfather Raman and asked him to run away from there. Raghunath was not aware of Meenakshi's pregnancy, so he went abroad when she was conceived. What will happen when Raghunath comes back from abroad and knows the truth? Will he ever see his son?
