Prathap, a police officer in
Bangalore, lives with his sister Lakshmi. They were raised by Pratap's superior, Chowdhary, who treats them as his own children. One day, Prathap and Chowdhary investigate the murder of a man named Dheerajlal and discover a diary. It reveals Dheerajlal’s real identity as Shankaralal who had been involved with a criminal gang led by Rathanlal and Peter, that ran a
child trafficking racket. After witnessing the gang’s brutal activities, including an
acid attack on a child, Shankaralal had felt guilty and decided to leave the gang. Prathap seeks Chowdhary's approval to go
undercover and bring down the gang. He travels to
Mumbai, and meets Nandanlal from the
Mumbai Police Department. Nandanlal reveals that Rathanlal and Peter died in an accident 25 years ago. Prathap meets his new superior, Chakravarthy, who explains that Inspector Gopal Rao, had been assigned to capture Rathanlal and Peter but had also died in the same accident. Prathap finds out that Nandanlal is connected to Shankarlal. Prathap gets captured by crime bosses Robert and Jeevanlal, who demand to know the reason for inquiries about Rathanlal and Peter. Prathap discovers that Nandanlal is working with them. Prathap fabricates a story and joins the gang, to escape execution. He learns about the gang's operations but his deception is exposed. In a bid to protect himself, Prathap uses Shankaralal’s diary to prove his knowledge of the gang’s activities. Nandanlal reveals that Jeevanlal and Robert are actually Rathanlal and Peter, who faked their deaths after killing Gopal Rao in a car accident. Prathap reveals that Shankaralal's death was orchestrated by Rathanlal and Peter. Prathap escapes with the help of Nandanlal. Nandanlal kills Peter to avenge his father's death but is later killed by Rathanlal. Prathap meets Chakravarthy, presents his findings, and plans to raid the gang’s hideout. His sister Lakshmi who arrives in Mumbai to meet him is confronted by Vijay (Rathanlal's son). Lakshmi kills Vijay in self-defense. Vijay's associates capture Lakshmi. Prathap arrives at the hideout to find Lakshmi dead. Enraged, he attacks Rathanlal and his associates. Prathap unmasks himself and declares that he is Gopal Rao’s son who had suffered an acid attack. He then violently confronts a terrified Rathanlal, who dies. ==Cast==
