Hossian Miya is a Bengali Muslim trader who offers his community an idealistic vision: He wants to establish a little utopia on an island in the Padma delta and offer them a better life there.

He would be fishing, except that the fish he usually catches have been driven away by a big storm. In the process of getting the cargo, he gets to see what the colony is like and, even though he is fully aware of the gripes of a former colony member and the limitations of it, comes to share some of the utopian vision.

Kuber tells his wife "Padda amago joto daay abar totoi loy". The storm wreaks havoc in the village. Hussian Miya offers to lend a helping hand to the villagers. He does so, but in return he takes their thumb impressions as proof of his help so that he can use it later to exploit them. Meanwhile, Kuber's daughter's marriage breaks down. Rasu proposes to marry her. Even though Rasu was close to Kuber, he refuses to accept the match because of the age difference between them. Rasu becomes furious and threatens to ruin Kuber.
