I'm not entirely sure who 'Indu Sarkar' specifically is without more context. There could be many people with this name. It could be an individual known in a particular community, a local figure, or someone with a more personal story. More details would be needed to accurately tell the'real story'.
The story of Indu Sarkar is said to be inspired by real-life events during the Emergency period in India, but it's not directly based on a specific individual.
I'm not entirely sure which specific 'Sarkar real story' you are referring to. There could be many stories or movies named Sarkar. It might be about a political drama, a family saga, or something else entirely.
