The film stars Parambrata Chatterjee, Paoli Dam, Soumitra Chatterjee and Santu Mukherjee.  This film is set against the background of the Naxalite movement.  Based on a 1980s novel by Samaresh Majumdar, the film sets itself up, quite self-consciously, within a certain tradition of films, namely radical political Bengali cinema of the 1970s and 1980s.  It thus establishes an intertextuality and a certain connection with them.  By situating itself and the story it has to tell, within this matrix of the 1970s radical Bengali cinema, Ghose anchors the film squarely within that time.  The mood and the events certainly, but even the way black and white shots are used, underlines a somewhat documentary – and thus temporally limited – way these sequences are put to use.
