Amidst the blockbusters and star-studded movies, we sometimes pay less attention to films that don't feature the so-called big names of Bollywood. But when a film's trailer makes you want to know more about the film, it deserves a special mention. The trailer of Nil Battey Sannata, starring Swara Bhaskar, Ratna Pathak, Pankaj Tripathi and Ria, is out and it surely shows that Bollywood has some beautiful gems to offer. The film is the story of a mother-daughter duo. The mother wants her daughter to pass her Class 9 exams and to set an example for her, she herself enrolls in a school to finish her education. The actors have done a beautiful job and we don't see such stories on the silver screen very often. Directed by Ashwini Iyer Tiwari, the film releases on April 22. Watch the trailer here:
