Basu Chatterjee is one of the few movie directors in Hindi filmdom who make simple yet absorbing films. Rajnighandha is no exception. It excels in its linear narration. Writer Manu Bhandari�s story Yehi Sach Hai inspired this delectable movie in which the boy-next-door Amol Palekar and his co-artiste in many a film, Vidya Sinha have done convincing parts. The movie had reasonably good run and did not disappoint at the box office.
Sanjay(Amol Palekar) is a happy-go-lucky young man in Delhi who is not very mindful of punctuality. He is also forgetful. Deepa (Vidya Sinha) is in love with him. In Bombay, where she is present for an interview, she comes face to face with Navin (Dinesh Thakur) , an old acquaintance with whom she had an acrimonious tiff. His meticulousness in everything he does and his caring attitude makes Deepa sway towards him. She is at a loss what to do with her life.
When she returns to Delhi, she concludes that her first love is the best and thinks of marrying Navin. She also gets a letter that she got her job in Bombay. Sanjay appears at her door to tell her of his promotion at the same time. Deepa now changes her mind and decides to marry Sanjay.
This is one of the many movies that Basu Chatterjee usually made sans mega stars and no pretensions. These movies did a world of good for Amol Palekar who later became a distinguished film maker himself.
