The play revolves around Sivaraman, (Kathadi Ramamurthy) a retired official, who desires to stay in an old-age home rather than with his son, and his efforts to help a young couple to adopt a child.
The curtain goes up with Shankar Mahadevan’s ‘Eka dhanthaya vakra thundaya gowri thanayaya deemahi’ playing in the background, and Ganesan (Sivaraman’s son) entering his office while talking to his wife Girija over the phone.
Ganesan gets miffed at her when she tells him his father Sivaraman should be sent to an old-age home. Listening to this exchange, Ganesan’s colleague Nandini offers to take care of his father. Though Ganesan initially hesitates because Sivaraman has dementia, (or that is what he makes everyone believe), he eventually agrees and shifts his father to Nandini’s house, much against her family’s wishes. Sivaraman’s arrival turns things for worse initially.
While Nandini’s mother-in-law Lalitha taunts her for refusing to have a child, Sivaraman overhears Nandini and her husband Vignesh talking about adopting a child. To help the young couple succeed in their mission, Sivaraman comes up with a plan. He involves an astrologer (Ganapathy Shankar) to make the mother-in-law agree to their decision.
