Roti made in the early 1940s inspired by the German Expressionism, is a real critique of Indian society with prophetic insight. It deals with two models - one of a millionaire, possessed by money and power in an industrial civilisation, the other of a tribal couple living in a primeval state of nature. The millionaire is saved by the couple after an air crash, the tribal couple emigrate to the city, do not find happiness and return. The millionaire is ruined in the city, tries futilely to find salvation among the tribal.
