1958. Mrinal Sen movie. Based on short story 'Chini Feriwala' by Mahadevi Verma. An unusual plot set in the 1930s. A Chinese immigrant in Calcutta who makes his living Chinese silk, makes friends with a rich progressive, politically active lady. When she calls him her brother he reciprocates her affection, having lost his younger sister in China. The story shows their platonic love, how society misunderstands them, how they treat it with maturity. Interesting characters.
