However, she leaves behind the baby in order to return to Sri Lanka, hoping that her husband is alive and wishing to continue in his footsteps. Nine years later in Madras, a young girl, Amudha lives a happy life with her father, the writer Thiruchelvan (better known by his pen name Indira), her mother, a newscaster and the 'real' Indira, and her two younger brothers, Vinay and Akhil. Amudha is close to her father while being more distant from her mother. On Amudha's ninth birthday, Thiruchelvan reveals to Amudha that she was adopted and her younger brothers are their biological children. Amudha is very disturbed after hearing the news and begins distancing herself from everyone else. Indira's father criticizes their decision, but Thiruchelvan and Indira are certain they have done the right move. Amudha asks her parents about her adoption. Nine years earlier in Rameswaram, Thiruchelvan, then a budding writer, often travels to a refugee camp and writes stories inspired by the people there. During one visit, Thiruchelvan sees a newborn baby girl and writes a short story about her. Indira is his neighbour, and has always been interested in him. Thiruchelvan wants to adopt the girl, but is not allowed to as a single man. He marries Indira and adopts the baby girl, naming her 'Amudha' at Indira's suggestion. A few years later, Indira gives birth to Vinay and Akhil. Still dissatisfied, Amudha requests to meet her biological mother despite Indira's insistence that she can't be found.

Amudha secretly goes to Rameshwaram with her cousin and finds her records. Shocked at her stubbornness, her family rushes there. Thiruchelvan gives in and agrees to take Amudha to Sri Lanka to find her birth mother. Leaving the two boys under the care of Indira's father, the trio travel to Sri Lanka and are meet Dr. Harold Wickramasinghe, a Sinhalese friend of Thiruchelvan who guides them.
