The subject of Rani Mukerji starrer 'Mardaani' had been kept under strict wraps as the makers felt that as a subject it was inherently very controversial.

However, we now hear from sources that the film is based on human trafficking. 

Not just that, sources close to the film unit say there have been a lot of high profile human trafficking stories that 'Mardaani' has taken inspiration from. 

While the makers are touting it to be a work of fiction, there is a tone of reality in every scene.
 
At the time when the script was being developed, the team working on it went back to older police files to incorporate it in the film.

Rani will be seen in a never seen before avatar playing the role of a cop in the film and there is a lot of excitement at YRF for this project.

Spokesperson of Mardaani says, "The central subject of the film is based on human trafficking. Writers have drawn inspiration from reality however no one knows which cases".
