Set on the Bihar-Bengal border, where Marwari businessmen - a powerful Hindi-dialect community of entrepreneurs much disliked throughout India - and Rajputs of warrior caste (from Rajasthan) have both settled. The central character of Narsingh (Soumitra Chatterjee), is a disillusioned, frequently drunken Rajput reduced in status to an ill-educated taxi driver. Proud and hot-tempered, with a passion for his 1930s Chrysler, Narsingh is offered work transporting tins of ghee for Sukhanram, a shady merchant, and finds himself drawn against his better judgement into trafficking opium.
