Amitabha, a screen-writer from Calcutta on a research trip in the country. When his car breaks down unexpectedly, he is taken in by Bimal, a wealthy tea plantation owner. At Bimal’s house, Amitabha is surprised to find that his benefactor’s wife, Karuna, is the woman he had been in love with years before, and had let down during their student days. The more he learns about Bimal, the more Amitabha realizes that the marriage cannot have been a happy one for Karuna. Amitabha next seeks an opportunity to tell Karuna that he has now the courage to take her away from her husband and thereby atone for his past betrayal.
