It's been adopted from Abu Ishaque's novel 'Surja Dighal Bari' which is a great work in Bengali literature.
This movie reflects wartime feminine at the time of WW2. Great acting along with unexpected simple flowing of narratives resulted in a impressive film. It sings a story of the Bengali mothers, who use to forget all miseries of thyself in affection to her childs, women who used to hurdle in life in the patriarchal society. And the lust of local influential persons who misbehaves with poor people taking the advantage of their scarcity.
