This is a story based of child abusing. In india there is many rude and cruel people like that man. and we should teach a lesson from the lady who fight for a little girl. vidya balan is perfect in this role.she played a role of a lady who suffer from child abusing and when she saw a little girl she remembered her childhood. it is verry nice movie. Arjun rampal is also played a good role in this movie.he is a police officer who helped vidya balan. In first kahani vidya played a role of pregnant lady and her husband was missing but in the second part she helped a little girl and in this movie sujoy ghosh who is the director of this movie.he done a great job in this movie.Kahani 2 is one of the best movie whic I seen this year. After watching this movie I felt so angry to the peoples who do this to his child. Vidya balan played a role of durga rani singh and for save the girl child she changed her name to bidya. In this movie I saw a power of women. A women Can do anything if she want. Overall the movie is awesome.
