We just saw Aishwarya Rai welcome the Duke and Duchess of Cambridge to Mumbai for the first time and now we finally get to see her back on the big screen. The trailer for her new upcoming biopic ‘Sarbjit’ has just been released and shows Aishwarya in a whole different light.

The film is based on the real life story of Sarbjit Singh, played by Randeep Hooda, who was an Indian farmer sentenced to death in Pakistan on charges of terrorism and spying but always maintained his innocence. Aishwarya plays his sister Dalbir Kaur, who fights unsuccessfully to get her brother released from prison.

The film focuses on the plight of Sarbjit’s family as they try everything to free him from jail. The film also showcases life inside Pakistani jails and how inmates are treated. According to reports, Sarbjit was kept in solitary confinement for 19 years in a room so cramped he couldn’t even stand upright. He was eventually killed by other jail inmates in April 2013. Based on the trailer, the film exposes the injustice and torture suffered by Sarbjit and his family. Both Randeep and Aishwarya give steller performances. Watch the trailer below!

When asked about her decision to take on the role of Dalbir, Aishwarya said this. “When Omung Kumar (the director of the film) came to me with the subject, it was an immediate yes. How can we walk away from telling such a story? This story needed to be told.” As for how she prepared to play Dalbir, Aishwarya revealed she had met the real Dalbir during the making of the film. She didn’t want to meet her before the making of the film as she wanted to stay true to the vision Omung had for her role. “When I am playing real life chartacters, it is important for me to stay true to the director’s vision and narrative.”

The film will be available on screen on May 20, 2016.
