"I hope the biopic will highlight the plight of Indian prisoners lodged in various jails in Pakistan," said Dalbir Kaur, who struggled for years to get her brother out of the Pakistani prison. He died following an attack on him by jail inmates in April 2013 in a Lahore prison.
His sister and family started a campaign for his release saying he was the victim of mistaken identity and had inadvertently strayed across the border in an inebriated state.
"I know the film is being made on a sensitive subject as it also involves two neighbouring countries, but the reality should come out. The plight of our prisoners in Pakistani prisons needs to be highlighted.
"I wish that once the film is released, it becomes a huge success. Even if one prisoner is released from Pakistani jail, I will think that 23 years of my struggle to secure the release of my brother, who could not return to his native land alive, has been successful," Dalbir Kaur, who hails from Bhikhiwind in Amritsar, told PTI over phone.
She said that Prime Minister Narendra Modi should watch the film once it is released.
