Some say it's a true story, presenting certain aspects of the Kashmiri situation. But there can be artistic liberties and interpretations taken for cinematic purposes.
Well, without having read 'the call girls novel', it might deal with themes like the social perception of call girls. It could show how they navigate a world that often stigmatizes them. Maybe it also delves into their dreams and hopes beyond their profession, like any other human being.
There could be a call girl who, while in the business, started writing a diary about her experiences. Eventually, she used those writings to create awareness about the hardships and the complex lives of women in such professions. This led to some positive changes in how society views them.
The 'Kashmiri Files' delves into the real story of the Kashmiri Pandits. During the 1990s, Kashmir witnessed a great upheaval. Kashmiri Pandits, who had been an integral part of the Kashmir valley for centuries, suddenly found themselves in a very dangerous situation. Militant groups were operating in the area, and the Pandits were seen as easy targets. There were killings, kidnappings, and a general atmosphere of fear. The movie shows how families were torn apart, how their cultural and religious heritage was in jeopardy. It also shows how the exodus of the Pandits was not just a physical movement but also an emotional and cultural rupture for them. They lost their homes, their communities, and in many ways, their identity that was so closely tied to the Kashmir valley.
The Kashmiri Pandits have a long and complex history. They are the original Hindu inhabitants of Kashmir. In the early 1990s, they faced a mass exodus from the Kashmir Valley due to a rise in militancy. Militant groups targeted them, leading to widespread fear. Many were forced to leave their homes, properties, and a way of life they had known for centuries. Their displacement has been a great tragedy, and efforts are still being made to help them resettle and regain their lost heritage in Kashmir.
I don't know the main characters in 'the call girls novel' as I haven't read it. But they could be the call girls themselves, maybe a particularly memorable one among them. There might also be characters like their clients, or people in their personal lives such as friends or family.
