Singaravelan "Velan", on his birthday, tames a wild bull by just talking to him. He seems to share a special bond with animals as he works in his farm filled with animals. Later that day, his mother, Parvathy, calls him and decides to tell him the truth about his late father. Velan, in his imagination, thinks that his father was killed by four goons (as is the case of many Tamil cinema then) but soon learns that his father did actually die of a brain illness like he had been told before. But, he had died heartbroken that his marriage with Velan's mother was not accepted by her sister-in-law and they had broken all links. Further, they believe that it was Parvathy's curse that killed her brother and sister-in-law in a car accident and they get a promise from the guardian, that their daughter should not be married to Parvathy's son. Velan's mother reveals that it is Velan's duty to get married to her brother's daughter Sumathi to bring the separated family back together. Armed with only a picture of the girl when she was four, he leaves for Madras to fulfill his mother's wishes.
