Chhoti Si Baat is an endearing, loveable, comedy about a young man who walks the rocky path of love because his heart is true but timid. Arun (AMOL PALEKAR) falls in love with Prabha (VIDYA SINHA) whom he sees everyday at the bus-stop on his way to work. Not having the courage or know how to express his love, all he can do is follow her to her office and her home and pine from afar. Just as he is wondering what to do next, along comes Nagesh (ASRANI), Prabha's brash young colleague who seems leagues ahead of Arun in his pursuit of Prabha. A now desperate Arun seeks the help of Colonel J.N.W. Singh (ASHOK KUMAR) who tackles the battle of love with the same meticulous planning and ruthless efficiency needed to win a military campaign. He instills in Arun a new self confidence and teaches him the strategies of waging love. Arun returns to Bombay a new man ready to face anything.
