Subarnarekha is an Indian Bengali film directed by Ritwik Ghatak. It was produced in 1962 but was not released until 1965. It was part of the trilogy, Meghe Dhaka Tara (1960), Komal Gandhar (1961), and Subarnarekha (1962), all dealing with the aftermath of the Partition of India in 1947 and the refugees coping with it.

From http://filmref.com/: Ritwik Ghatak's films are deeply haunted by the specter of the Partition of Bengal in 1947, and this sense of dislocation and self-inflicted human tragedy created by artificially imposed social division casts a pervasive sentiment of despair, instability, and perpetual exile through all the rended families and uprooted ancestral communities of Subarnarekha. Opening to the chaotic image of a pair of young, displaced teachers, Haraprasad (Bijon Bhattacharya) and Ishwar (Abhi Bhattacharya) inaugurating a makeshift village school at a refugee colony that has been established on the grounds of landowner's estate, while a low caste woman, seeking alms nearby, is forcibly separated from her son, Abhiram (Sriman Tarun) when she is rounded up into a truck and summarily ethnically cleansed from the colony by the landowner's hired thugs under the guise of religious orthodoxy enforcing caste segregation, the turbulent - and ultimately irrevocable - separation between mother and child serves as a potent metaphor for the trauma of the Partition itself, as Bengal is torn apart by religious and social sectarianism in the aftermath of the country's independence from the British.
