Chulbul Pandey, a young boy, lives with his younger half-brother, Makkhanchand “Makkhi” Pandey, stepfather Prajapati Pandey and mother, Naina Devi in Laalgunj, Uttar Pradesh. He has a troubled relationship with Prajapati and Makkhi. After 21 years, Chulbul becomes a policeman. Chulbul, who calls himself “Robin Hood” Pandey, still lives with his family. Makkhi is in love with Nirmala, whose father Masterji opposes the relationship. Chulbul falls in love with a girl named Rajjo, whom he meets during a police chase culminating in an encounter.
A corrupt political leader named Chedi Singh meets Chulbul and both quickly become enemies. Makkhi asks Prajapati to arrange his marriage with Nirmala. Prajapati refuses because he needs money to repay the loans he took to make his factory, and he believes that he can acquire money through his son marrying a rich girl. In desperate need of money, Makkhi steals some cash from Chulbul’s cupboard and gives the stolen cash to Masterji, hoping that he will permit Makkhi to marry Nirmala. Meanwhile, Chulbul meets Rajjo and proposes marriage, which she rejects, as she has to take care of her father, Hariya—a drunkard.
Chulbul comes home to find his mother, Naini Devi, dead. He goes to Prajapati to make peace, as he is the only family left. However, Prajapati refuses and despises him as an outcast. Makkhi invites Chulbul to his marriage with Nirmala. Chulbul convinces Hariya to marry Rajjo. Hariya commits suicide, as he knows that Rajjo will not marry anyone while he is alive. Chulbul takes Rajjo to Makkhi’s exuberant wedding. Realising that Makkhi has stolen his money to finance the wedding, Chulbul marries Rajjo in an impromptu ceremony. Masterji feels disgraced and cancels Makkhi’s wedding with Nirmala.
