Anand Verma resides in a modest home with his wife Sumitra and their two young sons Vijay Verma and Ravi Verma. He is a principled and well-respected trade union leader, who leads struggling labourers on a strike as they are depending on him to better their lives with concessions from their owner Badri Prasad. However, Prasad retaliates by kidnapping Anand's family and forcing him to sign a contract giving away the labourers' rights, in order to save his family's lives. When the striking labourers learn about Anand's actions, they all curse him and thrash him nearly to death, unaware that Anand was blackmailed to do so. The labourers even persecute Anand's family, and some of them drunkenly capture Vijay and tattoo his left arm with the Hindi words "मेरा बाप चोर है” (English: ("My father is a thief"). Unable to bear the humiliation, Anand escapes from the town and decides to spend his remaining life aimlessly traveling in trains, abandoning his family for whom he had abandoned his principles and ideals. In desperation, Sumitra brings Vijay and Ravi to Mumbai and resorts to low-wage manual labour to raise her sons alone. Their home is on the footpath under a huge bridge that is home to millions of homeless urban poor.

As Vijay and Ravi grow up in the slums of Mumbai, Vijay has an acute awareness of his father's humiliation, for he has been victimized for his father's supposed misdeeds, and is reminded of his past by the ever-present tattoo on his arm. He also refuses to enter a temple, stating that he wishes to chart his own destiny and not beg for it from the deities. Vijay Verma starts out as a shoeshiner and later becomes a dockworker in his youth, sacrificing his own education in order to enable Ravi to study. On the other hand, Ravi is a perfect citizen and is unwavering in his commitment to law and righteousness. Although he is unable to obtain gainful employment, Ravi romances Veera, the daughter of DCP Narang, by whom he is sent for police training and soon earns the rank of Sub-Inspector. In the process of fighting for his rights, Vijay refuses to pay the weekly extortion to the henchmen of the shipyard owner Samant, who is also a crime boss. Vijay proceeds to thrash several of Samant's henchmen, causing his mother Sumitra to berate him. Vijay sarcastically asks her whether she expects him "also" to escape like a coward, implying that he criticises his father's actions, causing a perturbed Sumitra to slap Vijay and half-heartedly defend Anand. The news of Vijay’s beating of Samant’s men reaches Samant's rival, Mulk Raj Daavar, who hires Vijay to protect his smuggled gold bullion that has been thrice hijacked by Samant. Vijay sells the information to Samant to help him hijack the gold bullion, takes the money from Samant, then captures the gold bullion from his warehouse and hands it over to Daavar, who rewards Vijay with a huge sum of money, allowing him to purchase a palatial home for his family.
