A little girl is told by her parents that she is adopted. Determined to find her birth mother, her family eventually agrees to take her to Sri Lanka, where they encounter the militant group known as the Tamil Tigers.

'Okkadu Migiladu' is the story of displaced Sri Lankan Tamilians who find themselves stuck with the tag of 'refugees' all their lives. The mistreatment they face both in India and Sri Lanka, with either country refusing to accept them as their own, forms the crux of the story.

Rajini, a Sri Lankan Tamil girl, narrates the horrific tale of why she had to leave her homeland and become a refugee in India.
