Rashmi, a young woman, is assaulted by a masked man and later diagnosed with AIDS. Shamed and isolated after being ordered into quarantine by the authorities, she takes her own life in despair.
Meanwhile, Police Commissioner (Navin Nischol) and his daughter Richa (Satabdi Roy) visit a remote village, where they meet Avinash (Uttam Mohanty), a local villager. Avinash becomes infatuated with Richa and follows her to the city, determined to pursue a relationship. In an attempt to build his confidence in sexual matters, Avinash seeks out a group of women associated with Devyani's gang, engaging in casual encounters.
After reuniting with Richa, Avinash suddenly experiences throat pain. A doctor diagnoses him with AIDS, leaving him devastated. Fearing quarantine, Avinash imprisons the doctor to prevent the news from spreading.
Consumed by anger, Avinash embarks on a violent revenge spree, targeting the women he believes infected him. He confronts Mrs. Dayal, a woman desperate for a child due to her husband's infertility. Upon learning she is pregnant, Avinash spares her. However, Mrs. Dayal is later killed by Devyani, but her baby survives.
His quest for vengeance ultimately leads him to Devyani Kamath, the leader of the gang. In a final confrontation, Avinash assaults her, but shortly afterward, she is killed in a bomb explosion.
In his dying moments, Avinash expresses his final wish to Richa, asking her to protect their unborn child from him and entrusting the child's future to her care.
