Master Dinanath is an ex-freedom fighter. When he gets Thakur Pratap Singh arrested for arms smuggling, he has Master's wife Bharati and young daughter Priti kidnapped and also turns his locality's public against him. Dinanath escapes with his young son Raju and they settle into a slum named Bharat Nagar. Meanwhile, Bharati contracts leprosy and escapes from her kidnappers, leaving her daughter Priti in a friend's care. Dinanath is led to presume that his wife and daughter are dead. Bharati Nagar is ruled by four underworld dons, each representing a different Indian community. Dinanath persuades them to live in harmony and once they settle their differences, the four dons use Dinanath's stay in Bharat Nagar to cover up their own illegal activities. Fast Forward to 15 years later, the year is 1962. Dinanath's now grown-up son Raju turns out to be the opposite of his father by being drawn into the underworld, committing crimes to earn money with his father unaware of what he does. Raju starts working for Thakur Pratap Singh, unaware that Thakur had once kidnapped his mother and sister many years earlier which caused their separation. Will Raju find out what Thakur did to his family? Will Dinanath find out his son is not what he thinks he is? And will Dinanath ever find his wife and daughter again?
