Vivek takes a job as the manager of Karunalayam, a retirement home. He meets a young woman called Akhila, who had sent her stepfather to jail for abusing her mentally ill mother, and they fall in love. Karunalayalam is financially in a bad state and the owner Eraadi wants to sell it off, but Vivek tries his best to save the retirement house, since the residents have nowhere else to go. Akhila's father is Siddharthan, who was poor and married Akhila's mother for money and her properties, as she was from a very wealthy family. As Akhila's grandfather died, Siddharthan learned that Akhila's grandfather did not gave any share of the properties to Akhila's mother. Siddharthan then leaves them. Akhila's uncle comes to Karunlayam to take Akhila and her mother to the tharavad (ancestral home). Vivek is saddened when Akhila leaves from karunalayam, one of the mothers in karunalayam asks him whether he loves Akhila to which he replies that he is not so lucky. Vivek plans to sell his kidney for 5 lakhs for saving the karunalayam home. Eraadi learns about this, and feels sympathy for Vivek so Eraadi gives all his properties to Vivek. At last Akhila and her mother go to karunalayam with two surprises for Vivek; one is to give a blank cheque to Vivek for keeping the mothers safe in Karunalayam and second is to fix the date for engagement of Akhila and Vivek.
