A golden thread of life passes through the experiences of refugees over two decades following WWII and also refers to a beautiful Bengali river.
Haraprasad and Ishwar are two moralistic men who attempt to scrape out some semblance of a dignified life for themselves and their dependents in the aftermath of Partition, where the subcontinent was split into two countries (later three), and the crisis that this caused to people who found themselves on the wrong side of borders where different theocratic ideals were playing out. The movie is set in Bengal (Bengal and Punjab were the two provinces that ended up with pieces on either side of the border).
Haraprasad is more of a believer in communal living, whereas Ishwar compromises and becomes a creature of the system. The main issue is that it didn't really matter what you did, leading a dignified and happy life weren't really possible. Human wellbeing is very fragile and our characters here suffer try as they might to readjust to their uprooting.
Director Ghatak tends to follow the stories of the middle classes, perhaps the worse route through life is a downwards one, and many middle class folk simply had their lives destroyed by Partition. The working classes are relatively ignored, although Ghatak is not blind to this: Ishwar can be complacent and there's a scene in a factory where he ignores the important request for leave from an employee, rather absent-mindedly. He had a nickname of "Ocean of thought" at university, the problem here is that as long as we might like to spend time in the idealistic hinterlands of our own minds, this can lead to ignoring others.
Part of Ghatak's charm is that he is self-aware, he knows that long stories of woe are not what people tend to want to watch, and yet he points out that maybe people should be concerned with their conditions, not just trying to momentarily escape them.
The wonderful symbolic cinematography is the best thing about this movie, I would love to see it in the cinema one day. Ghatak is also sensitive to the plight of women and Ishwar tends to have selective hearing towards them or to treat them like children, however well intentioned he may be. Another skill is the ability to evoke with small brushstrokes, The complete injustice of the differential access to politics enjoyed by the rich over the poor, is portrayed in a flash, the character Rambilas casually and callously mentions running for office as he believes the sacred caste system is under threat (the system which keeps him rich and others in grinding poverty and disesteem).
So what exactly is the golden thread? I think the golden thread is hope, the characters live on their hopes, and in admiration of natural beauty. Maybe this is enough. Maybe this is all there is.
