Balram "Ballu" Prasad, a wanted criminal, is apprehended by Inspector Ram, who is investigating the criminal activities of Roshan Da, Ballu’s mentor. During interrogation, Ballu refuses to disclose information about Roshan Da. While in custody, he escapes with assistance from his associates, which leads to public criticism and Ram's suspension.
To help restore Ram’s reputation, his fiancée and fellow officer, Inspector Ganga, volunteers for an undercover assignment. Disguised as a street performer, she locates Ballu and gradually earns his trust. Through their interactions, she learns about his history and the circumstances that led him to a life of crime.
Ballu develops romantic feelings for Ganga, unaware of her true identity. Upon discovering she is a police officer, he feels betrayed and becomes hostile. Despite this, Ganga continues her mission and refuses to withdraw from the assignment.
Meanwhile, Ram visits Ballu’s mother, Aarti, who reveals that Ballu and Ram were childhood friends. She explains how Roshan Da exploited their family’s difficulties and manipulated Ballu into believing that the police were responsible for his sister, Sunita’s death. This misinformation fueled Ballu’s tendencies to turn to a life of crime.
As the manhunt for Ballu intensifies, Ganga assists him in escaping during a police pursuit. She is subsequently arrested and charged with aiding a fugitive, damaging her professional standing and public image. Ballu, now in hiding, reunites with his mother but is attacked by Roshan Da, who views him as a threat.
Inspector Ram leads a police operation against Roshan Da. During the confrontation, Ballu learns the truth about his sister’s death and Roshan Da’s involvement. Ram kills Roshan Da during the operation, while Ballu manages to flee.
Learning that Ganga is on trial for assisting him, Ballu voluntarily returns, confesses to his crimes, and testifies that Ganga acted under official orders. His testimony leads to Ganga’s acquittal. Ballu is sentenced to life imprisonment.
