Rakesh Dhawan (Akshay Kumar) is a cool scientist who masks his shrewd intelligence behind jokes and songs. He dreams big and isn’t afraid to take blame for someone else’s mistakes. Life goes on, just the way it should, he says. Yet, when he gets badgered by Tara Shinde (Vidya Balan) into believing they can send the Mangalyan to Mars despite the failure of Geosynchronous Satellite Vehicle Launch of 2013 – he cannot resist the need to right the wrongs. Alongside him is a team of women comprised of characters played by Taapsee Pannu, Sonakshi Sinha, Nithya Menen, and Kirti Kulhari; supported by Sharman Joshi.
