B-Town beauty Rani Mukherjee is soon coming up with an action-adventure venture ' Mardaani '. The actress is all set to flaunt her fearless side in this flick, as she plays role of the crime branch officer Shivani Roy. Rani has already garnered loads of praises from all for her new avatar and action stunts in the trailer of ' Mardaani '.

Rani worked with the crime branch officials and various offices in order to get the real picture of their working and absorb the atmosphere. During this, she came across the issue of lack of basic facilities for female crime branch officials, such as no separate washrooms for females in the department. After knowing this, Rani planned to appeal to the Police Commissioners of different cities for providing basic facilities like separate washrooms for female officials in the crime branches. The actress perceived it as an extremely crucial issue that needed to get an immediate attention from the concerned authorities.
