the main theme. By this machine any one can make anybody sleep for hundreds of years. Everybody wants to have the unique machine by any means. Who will get that machine, that is the suspence. Key characters in the film are Soumitra Chatterjee, Biplab Chatterjee, Monu Mukherjee, Kharaj Mukherjee, Ramaprasad Banik, Joy Sengupta, Master Sourav Banerjee etc. Every actor and actress has performed their best. While watching this film the story, the camera, the background music sometimes remind great Satyajit Ray. Master Sourav Banerjee's acting especially bags appreciation.
