Muthiah, a farmer, manages to tame Neelamani, a bull owned by Maragatham, the daughter of a wealthy man. After Muthiah's victory, Maragatham challenges him to participate in a Rekla race. Muthiah participates and emerges victorious, and Maragatham falls in love with him. Muthiah's mother, while happy about the accolades her son has won, believes he is too playful and advises him to marry and live more responsibly. Muthiah's uncle agrees to talk to Maragatham's father and fix Muthiah's marriage with Maragatham, but has plans of his own. Instead of Muthiah, he finalises Maragatham's marriage with his spoilt son Velu.

On the day Maragatham is supposed to marry Velu, she and Muthiah elope and marry, and eventually have a son, Manickam. Maragatham inherits her father's wealth following his death. One day an elephant goes out of control, but Muthiah manages to overpower it, saving princess Indu in the process. She develops a liking for Muthiah and invites him and his family to the palace. Velu is jealous of Muthiah and, seeking to tarnish Muthiah's image, he spreads rumours about him and the princess. Eventually, Muthiah is forced to overpower a bull whose horns are laced with poison. Despite that, he succeeds and continues to live prosperously with his family.
