The plot is about a helpless girl Mary, left orphaned by the Tsunami. Father Puthusserry, a kind-hearted priest, builds a small house for her on church property and gets her a job as a salesgirl in a textile showroom. She lives there with her grandfather Charlie.
But Mary's grandfather, a drunkard, always takes away the money she earns. Mary's only relief is her friends Roy, Solomon and Shalom. She just manages to drag herself on through this rather dull and dreary existence, nursing all kinds of hopes in her heart. And then, all of a sudden, something good happens to this hapless girl!
