After Billoo's widowed mother, Kamla, passes away, he goes to live with Parvati and Shankar, and their three children, Ravi, Jyoti and Pinky. Billoo watches as Shankar gets killed by a goon, Than Than Tiwari, and swears to avenge this after fulfilling his responsibility of looking the rest of the family. First he drives a cycle-rickshaw, then makes sacrifices and purchases an auto-rickshaw to ensure that Ravi gets a good education and becomes a Collector, and that Jyoti and Pinky get educated and married. Jyoti then gets married to wealthy Vijay and moves out, while Pinky becomes abusive and befriends Munna Tiwari. Things get worse after Ravi decides to marry wealthy Nisha T. Mirchandani, refuses to study any further and moves out. But more shocks and trauma are to follow after Nisha becomes pregnant and decides to keep Parvati as her maid, takes-over Parvati's ancestral home - thus not only rendering Billoo homeless, unable to marry Asha, his childhood sweetheart, and never be able to fulfill his vow of vengeance.
