Thangadurai, Vishnu's father, wants to raise him to be cautious, but Vishnu wants to see the world and despises Thangadurai's overprotection, so he leaves home and works on an estate while claiming to be an orphan. Vishnu is raised as the estate owner's son. In the meantime, Vishnu develops feelings for Radha. Everything is going well for Vishnu until his adoptive father Rajamanikkam brings him a picture and demands that he kill the person in it to demonstrate his love for him. The man explains that he wants them killed since they killed his kid, which is why. Vishnu concurs right away but is startled to see Thangadurai in the picture.
