There, the dutiful son is peremptorily ordered to marry Susheela, daughter of a hapless widow. Ramesh refuses, confesses that his heart belongs to another. But the widow's fervent plea softens him ultimately. And he concedes, albeit with a heavy heart. The wedding takes place with due ceremony; and Ramesh sets out with his bride on a river boat journey back to Kolkata.
