There is no belief without believers. A young woman, 'Oorvazi', born into Zoroastrianism, the religion of her forefathers leaves the isolation of her remote home when her grandfather with whom she lives alone dies. He leaves her a mysterious message and an even more mysterious book. Oorvazi journeys to Mumbai, the city where the dwindling Zoroastrian community, an endangered species of believers lives. She is welcomed in her aunt's house by her aunt's adopted son who confesses that he still loves her. The meaning of the mystery her grandfather has left her with is revealed in layers as Oorvazi comes across figures from the historical past of the Zoroastrians. The mystery of the book too is revealed. Are these figures and the magical book real or figments of a philosophical imagination? Does her quest end in love or in understanding - or are these interchangeable or ultimately the same?
