Absolute laugh riot this movie. Made well ahead of its time. It's a kind of situational comedy attempted in Andaz apna Anna.
Well about the movie. There are group of corrupt officers who mistakely assume a orcehestran member to be of top CBI officer. To please him they try everything that's possible and what follows is hilarious turn of events.
Main star of this movie is Late Om Prakash. Watch out for his reaction when he confesses of taking bribes to astrologer.
