Mardaani 2 Trailer: Rani Mukherji's film promises to be gritty investigating thriller.

The first trailer for Mardaani 2, a stand-alone sequel to 2014’s fact-based thriller, has been released. Starring Rani Mukerji as a cop, the film appears to be a cat-and-mouse thriller inspired by real events.

The trailer opens with stats revealing to the viewer that more than 2000 rapes are committed in India by boys under 18 years of age every year and that these are only the ones that are reported. We watch a young girl hitch a ride home, followed by the screen cutting to black, with only her screams rattling in our ears as the Yash Raj Films logo pops up.

Mardaani 2 is based in Kota, Rajasthan, where a serial rapist is on the loose. While the trailer never really seems like a sensitive treatment of the subject - there are glimpses of the shocking crime and its aftermath - it takes another surprising turn when it turns into a thriller.

The criminal leaves her clues and threatens to commit more crimes, prompting her to put together a crack team and leave no stone unturned in nabbing him. 

Mardaani 2 is directed by Gopi Puthran and also stars Vikram Singh Chauhan. The film is slated for a December 13 release.
