A 14-year-old forlorn Kalyani delivers a boy in seclusion, fearing societal backlash and incapacity. She abandons him, heavy-hearted, placing him inside a moving goods train, which a slum dweller finds. The slum procures him as their common child, naming him Surya and they collectively raise him honest. He grows up, intolerant of injustice especially to the poor, though he wonders why his biological mother had impetuously abandoned him. A yellow shawl was the only identity he had of his mother, which she had placed him in when casting him away.
