30 years ago, Ranasingam always wanted a son but kept getting daughters. After four daughters with his first wife Vanavan Madevi (Viji Chandrasekhar), Ranasingam sought after 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 (Bhanupriya). Five months after Panchavan became pregnant, Ranasingam’s eldest daughter Mangamma Rani (Mounika) became pregnant out of wedlock and Ranasingam’s family arranged her marriage to her boyfriend, Thamarai Manala Sendayar (Saravanan). With both the stepdaughter and stepmother pregnant, odds went against Ranasingam as Panchavan gave birth to a girl while his elder daughter had a boy. Ranasingam was heartbroken and stopped worrying for a boy child.
8 years later, Vanavan became accidentally pregnant and finally gave birth to a boy, who was named Gunasingam. At the present, Gunasingam is a 27-year-old, 10th graduate, and a contented and happy farmer who practices natural farming and lives in peace. His concerns are:
1. His eldest sister’s husband Thamarai and next sister’s husband Malligai Manala Sendayar have been at loggerheads for a decade, despite being blood brothers. This is due to a court feud over inheritance and is complicated by the fact that Malligai has no pregnancy.
2. He must decide whether to marry either Poompozhil Chellamma (daughter of his third sister) or Aandal Priyadarshini (daughter of his only step-sister), as it is a societal norm in Tamil Nadu, for a man to marry his elder sister’s daughter in rural areas.
