Rani, 36, will be seen playing the role of a cop in the film directed by Pradeep Sarkar.
Apparently, the makers of the movie have taken inspiration from high-profile human trafficking stories. While the makers are touting it to be a work of fiction, there is a tone of reality in every scene.
"The central subject of the film is based on human trafficking. Writers have drawn inspiration from reality however no one knows which cases," spokesperson of 'Mardaani' said in a statement here.
The movie is directed by Sarkar, who last directed Rani in 'Laaga Chunari Mein Daag' (2007). 'Mardaani' produced by Yash Raj Films, will be released on August 22.
