Fighting a war which is very personal and in an obsessive hunt for the girl, Shivani stumbles into the world of debauchery, cruel desires and exploitation and onto a case that will change her life forever. What follows is a cat and mouse game between a fearless cop and a young and ruthless mafia kingpin.

Catch Rani Mukerji in the lead, playing an edge of the seat role of a lifetime, in this raw and gritty film which is a distinct departure from Pradeep Sarkar’s style of filmmaking, suggests Yash Raj Films.

Directed by Pradeep Sarkar and produced by Aditya Chopra, the film Mardaani will release worldwide on 22nd August 2014.
