Obviously Big B is the central character but all the characters have played very important role especially Taapsee, Kirti and Piyush Mishra. Piyush have argued very interestingly with the defense lawyer, Amitabh Bacchan in the court of law.
This is a story of 3 girls reside outside home in a pg. Incidentally one day they go for a party and there one of them hits a guy with a bottle as the guy tries to assault her sexually. Here the story begins. Then the boys start blackmailing her and eventually the case went to the court. Big B plays a role of a well known lawyer. At the end of the film Big B leads the case.
The story is based on the behavior of our society which is nicely drawn in the course of the court room drama. We should learn how the women must be treated.
