Doodh Ka Karz

Sapheran Parvati, along with her newborn son, Suraj, watches helplessly as her husband, Gangu, is wrongly accused of theft, and then beaten to death by Raghuveer Singh, Bhairav Singh, and Sampath. She cremates his body, nurses a snake and Suraj, and swears to avenge Gangu's death. She is looked after by Dharma Lohar, who assists her in bringing up Suraj. Years later Suraj has grown up, Parvati is all set to avenge Gangu's death and get him married to Dharma's daughter, Kajri.
