Sarabjit Singh died after a brutal attack by jail inmates in a Pakistani jail in 2013. He was convicted of terrorism and spying by a Pakistani court and sentenced to death in 1991 but the government had stayed his execution for an indefinite period in 2008. 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.
The film also stars Richa Chadha and Darshan Kumaar in pivotal roles.
Directed by Omung Kumar, 'Sarbjit' is slated to release on May 20.
