Perunazhi Gunasingam is a modern-day wealthy farmer who lives happily with his family and his father, Ranasingam.
Thirty years ago, Ranasingam always wanted a son but kept getting daughters. After four daughters with his first wife, Vanavan Madevi, Ranasingam sought a new bride to beget a son. Afraid of losing her status to a stranger, Vanavan arranged a marriage between Ranasingam and her younger sister, Panchavan Madhevi. Five months after Panchavan became pregnant, Ranasingam’s eldest daughter, Mangamma Rani, became pregnant out of wedlock, and Ranasingam’s family arranged her marriage to her boyfriend, Thamarai Manala Sendayar. With both the stepdaughter and stepmother pregnant, the odds went against Ranasingam as Panchavan gave birth to a girl while his elder daughter had a boy. Ranasingam was heartbroken and stopped worrying about a boy child.
8 years later, Vanavan became accidentally pregnant and finally gave birth to a boy named Gunasingam. Now Gunasingam is a 27-year-old, 10th graduate, and a contented and happy farmer who practices natural farming and lives peacefully. His concerns are:
However, problems arise when Gunasingam falls head over heels for Kannukiniyal “Iniya”, the daughter of a rich man, Thillainayagam, whose sister Ranasingam had suddenly left during his engagement to oversee the birth of his fourth daughter. Despite resistance from Iniya’s family, Ranasingam agrees to the match, provided that Gunasingam must convince his sisters that he cannot marry their daughters. Also, Iniya’s uncle, Kodiyarasu, was jailed for the work of Gunasingam and seeks to get revenge by killing him. When Chellamma learns of Gunasingam’s decision, she attempts suicide but is saved.
Panchavan vacates Ranasingam’s house because she feels that her elder sister continuously commits injustices against her, like arranging her marriage without her permission, getting Panchavan’s only daughter married to an ill drunkard who died within a year, and now refusing to marry her granddaughter, Andal, to Gunasingam. As revenge, Kodiyarasu offers to marry Chellamma, and that offer is accepted. Thamarai is willing to attend the marriage only if his brother does not; the same goes for Malligai. Finally, Gunasingam gathers all his relatives to his grandmother’s function and convinces them after a moving speech. Later, Kodiyarasu is thrashed by Gunasingam and returned to prison. Meanwhile, Gunasingam’s brothers-in-law amend their dispute, and everyone attends Gunasingam’s wedding to Iniya.
A year later, Gunasingam and Iniya give birth to a girl and choose to adopt permanent birth control to ensure that past events do not repeat themselves.
